How to backup and restore a MySQL database on Windows and Linux

April 21, 2019 by Simon

Why backup and restore

This is a quick guide demonstrating how you can backup and restore a MySQL database on Windows and Linux using Adminer.

You may need to know how to backup a restore a database for a number of reasons..

e.g

Send the database to someone to debug or give feedback while learning.
Move the database from a local machine to the cloud
Move the database from cloud vendor A to cloud vendor B
etc.

Having a backup of the VM is good but having a backup of the database too is better. I use UpCloud for hosting my VM’s and setting backups is easy. But I cannot download those backups.

Murphy’s Law

“If anything can go wrong, it will”

The most important reason for taking a backup and knowing how to restore it is for disaster recovery reasons.

Backup (the easiest way) with Adminer

Adminer is a free PHP based IDE for MySQL and other databases. Simply install Adminer and save the file on your local computer or remote web server directory.

FYI: The Adminer author Jakub Vrana has a patron page, I am a patron of this awesome software.

Snip from Adminers website. “Adminer (formerly phpMinAdmin) is a full-featured database management tool written in PHP. Conversely to phpMyAdmin, it consist of a single file ready to deploy to the target server. Adminer is available for MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, Firebird, SimpleDB, Elasticsearch andMongoDB.”

TIP: The file would be publicly accessible to anyone so don’t save it to a common area, obfuscate the file, protect it of delete the file when you are done using it.

Once Adminer is installed load it in a web browser, login with your MySQL credentials. Once you login you will see all databases and an Import and Export menu.

Adminer main screen, all databases and import and export menu.

tbtest is a simple database with one table and 4 fields (ID, Key, Value and Modified)

.Click Export to open the export screen.

Export screen showing a list of databases and export options

Click Export, a SQL file will be generated (this is the export of the database).

Here is a save of the file:
https://fearby.com/wp-content/uploads/export.txt

Exported view of https://dev.mysql.com/doc/workbench/en/wb-admin-export-import-management.html

Its that simple.

If I add a binary blob file to the table and upload a PNG file lets see how the export looks.

Screenshot o the new table with a blog field in Adminer UI

Let export the database again in Adminer and check out the output. I used Sublime Text editor to view the export file.

New Export shows the binary file in the Backup SQL file

Restore (the easiest way) with Adminer

OK lets delete the tbtest database and then restore it with Adminer. I used Adminer to delete (DROP) the database.

Database “dbtest” deleted.

Now lets create a blank database to restore to (same name).

Database created.

Now lets import the database backup using Adminer.

Click Import, select the backup file and un-tick Stop on errors.

Import screenshot, dxtest selectded, Restore file selected, stop on errors disabled

TIP: The 2MB next the the choose file button is defined by your web server and PHP configuration. If you are trying to import a larger database (e.g 80MB) first increase the limits in your web server and PHP (via php.ini).

The Import (restore should take seconds)

The database was imported from a backup, all tables and records imported just fine.

Bonus methods.

On Ubuntu use this guide to backup from the command line. If you use the Oracle MySQL Workbench read this.

I hope this helps someone.

Setup a Certification Authority Authorization (CAA) DNS record(s) to prevent https cert issue/misuse

March 18, 2019 by Simon

On February 22nd 2017 CAA’s that issue https certificates are required to check what CAA’s are allowed to issue HTTP’s certificates for a website. To limit who can create HTTP’s certificates for your site all you need to do is specify a number of DNS records.

DNSSEC

Before adding DNS CAA records ensure you have enabled DNSSEC for extra security, this is not needed to setup CAA records but it’s a good idea.

DNSSEC Explained

Read my post here on setting up DNSSEC with Cloudflare here.

Namecheap allows you do set DNSSEC with 1 click (making the above guide not required unless you use Cloudflare).

Testing DNSSEC

First, test DNSSEC on your website here: https://dnssec-analyzer.verisignlabs.com/ (I already have DNSSEC enabled)

I use Namecheap for buying domains and HTTP’s certs (you can buy a new domain here). Namecheap allow you to easily enable DNSSEC and CAA DNS records.

Read Namecheap’s CAA guide here.

Scott Helme tagged a great write up on CAA here.

CAA is probably the best bang for buck you’re going to get! https://t.co/pvThaQ8qFl
— Scott Helme (@Scott_Helme) March 14, 2019

Testing CAA (on your website)

Go to https://dev.ssllabs.com/ssltest / and scan your website

https://dev.ssllabs.com screenshot showing a domain input box

You will see if CAA is enabled after the https test is complete (scroll past the rating)

In my case CAA records were not detected.

Adding DNS CAA records at Namecheap

I logged into Namecheap, clicked Manage domain and clicked the Advanced DNS tab

Screenshot showing Namecheap Advanced DNS screen.

I click Add New Record (DNS), then I selected CAA

Screenshot of add NDS CAA record at Namecheap

Here are records for my main domain (allowing Comodo/Sectigo HTTP’s certificates only)

Type, Host, Value, TTL

CAA Record @ 0 issue "comodoca.com" Automatic
CAA Record @ 0 issue "comodo.com" Automatic
CAA Record @ 0 issue "usertrust.com" Automatic
CAA Record @ 0 issue "trust-provider.com" Automatic
CAA Record @ 0 issue "sectigo.com" Automatic

Here is my record allowing a sub domain (allowing Lets Encrypt HTTP’s certificates only)

Type, Host, Value, TTL

CAA Record audit.fearby.com 0 issue "letsencrypt.org" Automatic

It is also possible to setup email alerts of CAA violations where CAA’s support it. I setup a [email protected] email alias.

Type, Host, Value, TTL

CAA Record audit.fearby.com 0 iodef "mailto:[email protected]" Automatic
CAA [email protected] 0 iodef "mailto:[email protected]" Automatic

Image of my final Namecheap DNS config.

Screenshot os Namecheap DNS entries (table below)

Test CAA Records

I visited https://dev.ssllabs.com/ssltest / and performed a final scan.

Pass 🙂

I do have real time remote server monitoring reporting on https presence and uptime, read the post here.

Plug(s)

Warning

I had an issue where I failed to update my DNS (and define a CAA record) for the sub domain used for Nixstat reporting. I was receiving this error.

dev.ssllabs.com was reporting the cert expired?

The awesome chat support (Vincent) over at Nixstats found out it was because I did not have CAA record for the sub domain allowing “letsencrypt.org” to generate certs.

Created CAA record for status.feabry.com (CAA 0 issue "letsencrypt.org"

If you manually renew a Lets Encrypt cert with the following command without a CAA record you will see an error

> certbot -q renew

Error Output

Attempting to renew cert (subdomain.fearby.com) from /etc/letsencrypt/renewal/
subdomain.fearby.com.conf produced an unexpected error: Failed authorization procedure.
subdomain.fearby.com (http-01): urn:acme:error:caa :: CAA record for
subdomain.fearby.com prevents issuance. Skipping.
All renewal attempts failed.

DNS additions and changes take a while to propagate so monitor Whats My DNS for change status

https://www.whatsmydns.net/#CAA/status.fearby.com

Thanks for reading.

For simplicity I have removed all sub domain CAA settings for records and only set global ones

Updating NGINX to the development branch to get more frequent updates and features over the stable branch

November 20, 2018 by Simon

Updating NGINX to the development branch (on Ubuntu) to get more frequent updates and features over the stable branch

Aside

I have a number of guides on moving away from CPanel, Setting up VM’s on UpCloud, AWS, Vultr or Digital Ocean along with installing and managing WordPress from the command line. View all recent posts here https://fearby.com/all/

Now on with the post

Warning

Backup your Nginx and Server before making any changes. The Nginx development branch is quite stable but anything can happen. If your site is mission critical then stay on the stable branch.

Nginx Branches

By default, you will most likely get the stable branch of Nginx when instaling and updating Nginx. I have been running the stable version for the last few years but was made aware of a DDoS vulnerability in Nginx.

Here is a good write-up on development merges into the stable branch.

Nginx Updates

Widely-used #Nginx server releases versions 1.15.6 and 1.14.1 to patch two HTTP/2 implementation vulnerabilities that might cause excessive memory consumption (CVE-2018-16843) & CPU usage (CVE-2018-16844), allowing a remote attacker to perform #DoS attackhttps://t.co/1Z3JoghoBr pic.twitter.com/qQ3pOFD1Lk
— The Hacker News (@TheHackersNews) November 9, 2018

I was aware recently of a DDoS bug affecting Nginx and the recommendation was to update ot Nginx 1.15.6 development branch (or 1.14.1 stable branch).

A few days ago no 1.14.1 update was available but a 1.15.6 was, should I switch to the development branch to get updates earlier?

Reminder to update your #nginx installations to the 1.14.1 stable or the 1.15.6 mainline versions for critical security patches released this week. #NGINXPlus customers, see instructions for updating based on the patch released 10/30 https://t.co/KitsOWIJkb

    *) Security: when using HTTP/2 a client might cause excessive memory
       consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).

    *) Security: processing of a specially crafted mp4 file with the
       ngx_http_mp4_module might result in worker process memory disclosure
       (CVE-2018-16845).

    *) Feature: the "proxy_socket_keepalive", "fastcgi_socket_keepalive",
       "grpc_socket_keepalive", "memcached_socket_keepalive",
       "scgi_socket_keepalive", and "uwsgi_socket_keepalive" directives.

    *) Bugfix: if nginx was built with OpenSSL 1.1.0 and used with OpenSSL
       1.1.1, the TLS 1.3 protocol was always enabled.

    *) Bugfix: working with gRPC backends might result in excessive memory
       consumption.


Changes with nginx 1.15.5                                        02 Oct 2018

    *) Bugfix: a segmentation fault might occur in a worker process when
       using OpenSSL 1.1.0h or newer; the bug had appeared in 1.15.4.

    *) Bugfix: of minor potential bugs.


Changes with nginx 1.15.4                                        25 Sep 2018

    *) Feature: now the "ssl_early_data" directive can be used with OpenSSL.

    *) Bugfix: in the ngx_http_uwsgi_module.
       Thanks to Chris Caputo.

    *) Bugfix: connections with some gRPC backends might not be cached when
       using the "keepalive" directive.

    *) Bugfix: a socket leak might occur when using the "error_page"
       directive to redirect early request processing errors, notably errors
       with code 400.

    *) Bugfix: the "return" directive did not change the response code when
       returning errors if the request was redirected by the "error_page"
       directive.

    *) Bugfix: standard error pages and responses of the
       ngx_http_autoindex_module module used the "bgcolor" attribute, and
       might be displayed incorrectly when using custom color settings in
       browsers.
       Thanks to Nova DasSarma.

    *) Change: the logging level of the "no suitable key share" and "no
       suitable signature algorithm" SSL errors has been lowered from "crit"
       to "info".


Changes with nginx 1.15.3                                        28 Aug 2018

    *) Feature: now TLSv1.3 can be used with BoringSSL.

    *) Feature: the "ssl_early_data" directive, currently available with
       BoringSSL.

    *) Feature: the "keepalive_timeout" and "keepalive_requests" directives
       in the "upstream" block.

    *) Bugfix: the ngx_http_dav_module did not truncate destination file
       when copying a file over an existing one with the COPY method.

    *) Bugfix: the ngx_http_dav_module used zero access rights on the
       destination file and did not preserve file modification time when
       moving a file between different file systems with the MOVE method.

    *) Bugfix: the ngx_http_dav_module used default access rights when
       copying a file with the COPY method.

    *) Workaround: some clients might not work when using HTTP/2; the bug
       had appeared in 1.13.5.

    *) Bugfix: nginx could not be built with LibreSSL 2.8.0.


Changes with nginx 1.15.2                                        24 Jul 2018

    *) Feature: the $ssl_preread_protocol variable in the
       ngx_stream_ssl_preread_module.

       ignored if the number of worker processes was specified after the
       "listen" directive.

    *) Bugfix: when using OpenSSL 1.1.0 or newer it was not possible to
       switch off "ssl_prefer_server_ciphers" in a virtual server if it was
       switched on in the default server.

    *) Bugfix: SSL session reuse with upstream servers did not work with the
       TLS 1.3 protocol.


Changes with nginx 1.15.1                                        03 Jul 2018

    *) Feature: the "random" directive inside the "upstream" block.

    *) Feature: improved performance when using the "hash" and "ip_hash"
       directives with the "zone" directive.

    *) Feature: the "reuseport" parameter of the "listen" directive now uses
       SO_REUSEPORT_LB on FreeBSD 12.

    *) Bugfix: HTTP/2 server push did not work if SSL was terminated by a
       proxy server in front of nginx.

    *) Bugfix: the "tcp_nopush" directive was always used on backend
       connections.

    *) Bugfix: sending a disk-buffered request body to a gRPC backend might
       fail.


Changes with nginx 1.15.0                                        05 Jun 2018

    *) Change: the "ssl" directive is deprecated; the "ssl" parameter of the
       "listen" directive should be used instead.

    *) Change: now nginx detects missing SSL certificates during
       configuration testing when using the "ssl" parameter of the "listen"
       directive.

    *) Feature: now the stream module can handle multiple incoming UDP
       datagrams from a client within a single session.

    *) Bugfix: it was possible to specify an incorrect response code in the
       "proxy_cache_valid" directive.

    *) Bugfix: nginx could not be built by gcc 8.1.

    *) Bugfix: logging to syslog stopped on local IP address changes.

    *) Bugfix: nginx could not be built by clang with CUDA SDK installed;
       the bug had appeared in 1.13.8.

       sockets to work with datagrams on Linux.

    *) Bugfix: in memory allocation error handling.

Development branch changes are made every few weeks and stable branch changes are made less often.

Updating Nginx

Normally you update Nginx bu running an update and upgrade

apt-get update && apt-get upgrade

Restart Nginx for good measure

/etc/init.d/nginx restart

Checking NGINX Version

nginx -v
nginx version: nginx/1.14.1

Changing your repository to the development branch

I changed ot the development branch by running

sudo add-apt-repository ppa:nginx/development

Update and upgrade Nginx

apt-get update && apt-get upgrade

Restart Nginx for good measure

/etc/init.d/nginx restart

Checking NGINX Version

nginx -v
nginx version: nginx/1.16.6

Removing the stable Nginx repository

Run this command to remove the stable branch of Nginx

sudo add-apt-repository -r ppa:nginx/stable

Check to see if the development branch is listed

grep -r --include '*.list' '^deb ' /etc/apt/sources.list* |grep nginx
/etc/apt/sources.list.d/nginx-ubuntu-development-bionic.list:deb http://ppa.launchpad.net/nginx/development/ubuntu bionic main

How to install PHP 7.2.latest on Ubuntu 16.04

November 17, 2018 by Simon

How to install PHP 7.2.latest on Ubuntu 16.04/ Ubuntu 18.04/Debian etc/

I have a number of guides on moving away from CPanel, Setting up VM’s on UpCloud, AWS, Vultr or Digital Ocean along with installing and managing WordPress from the command line. PHP is my programming language of choice.

PHP has a support page that declares the support date ranges and support types: http://php.net/supported-versions.php

A version of PHP is either actively supported, security fix supported or end of life. Read this post to check WordPress for PHP compatibility.

From time to time vulnerabilities come up that require PHP updates to be applied.

Multiple flaw found in #PHP, most severe of which could allow arbitrary code execution
Affected Versions:
PHP 7.2 —prior to 7.2.5
PHP 7.1 —prior to 7.1.17
PHP 7.0 —prior to 7.0.30
PHP 5.0 —prior to 5.6.36https://t.co/TtiqXePoHu
Upgrade to the latest version of PHP immediately
— The Hacker News (@TheHackersNews) May 1, 2018

#PHP 7.2.12 has been released https://t.co/iNXGYTs0PX
— Neustradamus (@neustradamus) November 9, 2018

Source Link here

I have guides on setting up PHP 7 here on Digital Ocean, here on AWS and here on Vultr. I have tried upgrading to PHP 7.1 in the past with no luck (I forgot to change something and rolled back to 7.0).

FYI: I have a guide on setting up PHP child workers so the output from some commands below may be different than yours. Here are the steps I performed to install PHP 7.2 alongside 7.0 then switch. to 7.2.

Backup your system

Do perform a Snapshot or Backup before proceeding. Nothing beats a quick restore if things fail.

Note: Use this information at your own risk.

Updating php 7.2.12 to 7.2.12

Update your Ubuntu systems

apt-get update && apt-get upgrade

Updating from an older php (e.g 5.x, 7.1, 7.1 to say 7.2.12)

Backup PHP

cd /etc/php
zip -r php7.0backup.zip 7.0/

Install Helper

This software provides an abstraction of the used apt repositories. It allows you to easily manage your distribution and independent software vendor software sources. More Info

apt-get install python-software-properties

Add the main PHP repo (more information)

add-apt-repository ppa:ondrej/php

Update the package lists

“In a nutshell, apt-get update doesn’t actually install new versions of the software. Instead, it updates the package lists for upgrades for packages that need upgrading, as well as new packages that have just come to the repositories.” from here

apt-get update

List Installed Packages (optional)

dpkg -l

Install PHP 7.2

apt-get install php7.2

Install common PHP modules

apt-get install php-pear php7.2-curl php7.2-dev php7.2-mbstring php7.2-zip php7.2-mysql php7.2-xml

Install PHP FPM

apt-get install php7.2-fpm

Update all packages (may be needed to update from php 7.2.4 to 7.2.5)

sudo apt-get upgrade

Edit your NGINX sites-available config

sudo nano /etc/nginx/sites-available/default
# I set: fastcgi_pass /run/php/php7.2-fpm.sock;

Edit your NGINX sites-enabled config

sudo nano /etc/nginx/sites-enabled/default
# I set: fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;

I edited these lines

location ~ \.php$ {
    ...
    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    ...
}

Edit your PHP config (and make desired changes)

sudo nano /etc/php/7.2/fpm/php.ini

Edit your PHP pool config file (as required). See this guide here.

e.g.

> cgi.fix_pathinfo=0
> max_input_vars = 1000
> memory_limit = 1024M
> max_file_uploads = 8M
> post_max_size = 8M

sudo nano /etc/php/7.2/fpm/pool.d/www.conf

Make sure you set: listen = /run/php/php7.2-fpm.sock

Set PHP 7.2 as the default PHP

update-alternatives --set php /usr/bin/php7.2

Check your PHP version

php -v

Reload PHP

sudo service php7.2-fpm reload

Reload NGINX

nginx -t
nginx -s reload
/etc/init.d/nginx restart

Check the status of your PHP (and child workers)

Add two factor auth login protection to WordPress with YubiCo hardware YubiKeys and or 2FA Authenticator App

October 28, 2018 by Simon

Here is a quick guide to show you how to add two-factor auth login protection to WordPress with YubiCo hardware YubiKeys and or 2FA authenticator app

Using the Yubico YubiKey NEO hardware-based two-factor authentication device to improve authentication and logins to OSX and software

October 4, 2018 by Simon

This post aims to show you how you can use a Yubico YubiKey NEO hardware-based two-factor authentication device to improve authentication and logins to OSX and other software and services.

Background

Although I am a developer I do like security related topics and I try and do as much as I can to secure my systems and applications. Reading the Multi-Factor Authentication Wikipedia page has all the details on Multi-Factor authentication.

I have been a big fan of 1Password to generate strong and unique passwords for separate accounts for a while now. Read my guide on upgrading from a standalone 1Password licence to a 1Password subscription. I love generating unique and complex passwords with 1Password.

But what happens if someone gets access to my 1password vault? Yubico has a catalogue of support services that I can use Yubikeys with to have, 1password is one supported service 🙂

I want to add Yubico protections with these services.

macOS Logins (DONE)
macOS Screensavers (DONE)
1Password (DONE)
Dropbox (DONE)
Twitter (DONE)
Google (DONE)
Google GSuite (DONE, WAITING TO VERIFY)
Google GMail (DONE)
Google Analytics and AdSense (DONE)
Github (DONE)
Thunderbird Email (DONE)
Debian servers in the cloud (SSH) (DONE)
Ubuntu servers in the cloud (SSH) (DONE)
Securing WordPress (DONE)

Etc

Final Warning

Do not attempt to activate Two Factor Authentication on a system unless you…

A) Have backups of your data
B) Have backup methods of getting into your account(s)

Murphy’s Law: “Anything that can go wrong will go wrong”

You never know when a Two Factor Authentication Key may die or an Authenticator app or a Mac/PC may stop working so always have a backup method just in case.

General

General Yubico YubiKey Setup guides https://www.yubico.com/setup/

Buying a Yubico YubiKey

International visitors can buy a YubiKey from the official store here. Australian readers can buy a key locally here. I grabbed 2x YubiKey YubiKey Neo 4 (with NFC) for $50 USD (about $75 AUD) each.

This blog post will aim to show how you can set up a primary key and backup key for use on macOS and other apps to add hardware-based two-factor authentication to logins.

Authenticator Apps

You can use Google Authenticator, Yubico Authenticator or freeOTP from https://freeotp.github.io

Plugging the YubiKey into macOS Mojave

First I read this guide: https://www.yubico.com/works-with-yubikey/catalog/macos/

1) I plugged in my Yubico Neo key into my USB slot.
2) I closed the Keyboard setup window that appeared (I guess the YubiKey is a kind of a keyboard to allow inserting of challenge-response character streams into apps and websites).

3) I followed the basic troubleshooting page and confirmed that the key was being detected (yes it was.)

4) I followed this guide to test U2F functionality and this guide to test OTP functionality. Web pages and Google Chome can talk to the plugged-in YubiKey(s).

I was prompted to register a UTF deice (and create an account)

I was prompted to (insert) and touch my Yubico key.

Google Chome asked for some permissions first.

FYI: Chrome 67 is recommended to securely allow the reading of UbiKey’s from web pages. Only allow sites you trust access to your USB devices and use a modern browser.

Success, Chrome could now see my YubiKey and my device was now verified.

Technical data is available to let you know what is going on in the background. I am not going to break down how this works but Yubico has in-depth whitepapers and documentation if you are interested.

Nice

Configuring OSX

I logged into my Mac with the account that I was going to secure.

I performed a complete time machine backup before proceeding. If you lock yourself out you will need to restore OSX from a Time Machine backup.

I Read the “Using Yubico Pluggable Authentication Module (PAM) with Challenge-Response” login guide: https://www.yubico.com/wp-content/uploads/2016/07/yubico_YubiKeyMacLoginGuide_en.pdf

I downloaded the Download the YubiKey Manager

I downloaded the yubikey-manager from here so I could configure the keys to use “HMAC-SHA1 Challenge-Response”.

Oops, I downloaded the wrong tool, good to know this one exists though.

I will update what this tool does in future (update firmware?)

I Downloaded the Yubikey Personalization Tool

I went back to the Yubico download page and downloaded the Personalization tool.

Many options are available here.

It’s time to configure a primary and backup (duplicate YubiKey) for use with macOS etc.

Enable Challenge Response

I opened the YubiKey Personalization Tool, Inserted my primary key, clicked the Settings tab, and in the Logging Settings group, selected Log configuration output and Yubico format.

I then clicked on the Challenge Response Tab, clicked the HMAC-SHA1 button, selected Configuration Slot 2, ticked “Program Multiple YubiKeys“, changed the “Parameter Generation Scheme = Same for all Keys“, Selected “Fixed 64 byte input” under “HMAC-SHA1 Parameters” and generated a new key (wrote it down).

Under “Configuration Protection” then I selected Enable Protection” I then visited here and generated a 6 digit string to convert to hex array (with spaces (e.g: “70 61 73 73 77 64”)).

Warning: If you set an access code and later forget it, you cannot make any programming changes to this YubiKey. You would need to buy another YubiKey.

I clicked on Write Configuration

If you chose Configuration Slot 1 you will receive a warning about not saving over Configuration Slot 1 due to Yubico VIP/Symantec, I personally do not trust Symantec or the https://vip.symantec.com/ service due to Symantec issuing non-compliant certificates for use on websites. Yubico allows you to swap configuration slots if want to keep the configuration data.

On the output of the first write, I was prompted to save a file. I saved this to “secretkey.csv” onto the Desktop.

When the write to my primary key was successful, I ejected it then inserted my backup key and wrote the same configuration data to it too (on Configuration Slot 2).

Testing the HMAX-SHA1 Challenge

I open the YubiKey Personalization Tool, then click the Tools tab and click Challenge Response. Choose Configuration Slot 2, I selected HMAC-SHA1. I typed a sample input challenge (e.g “hello world”) and clicked Perform.

I noticed the Yubico key touch panel was flashing. I pressed the button, then a response appeared below the input textbox. I copied this response text then insert your second key and perform the same test so I could compare the responses (they should be the same). They were.

If the responses don’t match rewrite the configuration to your primary and secondary keys and ensure the same key and secret was used for both keys.

FYI: I rewrote configuration a few times until I got it right.

Installing the Pluggable Authentication Module (PAM) on macOS

I re-read the Mac login guide here as I don’t want to lock myself out of my Mac.

I opened the Yubico Software Download page here and clicked Computer Login Tools and downloaded the PAM for Mac.

I installed the PAM package and verified the package installation with this command.

ls -al /usr/local/lib/security

Output:

Text Output:

> drwxr-xr-x 3 root wheel 96 9 Oct 10:29 .

> drwxrwxr-x 74 simon admin 2368 9 Oct 10:29 ..

> -rwxr-xr-x 1 root wheel 143172 20 Apr 21:13 pam_yubico.so

Backup macOS

Again I ensured my Mac was backed up with Time Machine.

I logged in to my Mac with the account I wanted to be protected with the Yubico YubiKeys.

I ran the following command in terminal

mkdir –m0700 –p ~/.yubico

I double checked that my Yubico key(s) were set up for challenge response (above).

I inserted my Uubico key and ran this command

ykpamcfg -2

Feel free to read the “ykpamcfg” manual here. The yubico-pam source code is located here.

Output:

The contents of “/Users/simon/.yubico/challenge-#######” looked like (I replaced 232 random chars with #’s below). The filename ended with my keys serial number.

v2:########################################################################################################################################################################################################################################:10000:2

Next, I was supposed to copy the challenge output from ykpamcfg to /var/root/.yubico/challenge-[YUBIKEY SERIAL NUMBER] with this command..

sudo cp /var/root/.yubico/challenge-[YUBIKEY SERIAL NUMBER] /Users/[USERNAME]/.yubico

But I had this error.

No such file or directory

Weird as the source file existed?? macOS issues?

I Opened /Users/[USERNAME]/.yubico/challenge-[YUBIKEY SERIAL NUMBER] in the nano editor (sudo elevated process) and saved the file to /var/root/.yubico/challenge-[YUBIKEY SERIAL NUMBER].

I reopened my terminal and verified the contents of /var/root/.yubico/challenge-[YUBIKEY SERIAL NUMBER]. The file is now there.

Permissions on the file is “-rw——-“. Good.

I inserted my second backuP key and re-ran “ykpamcfg -2” and copied the file to “/Users/simon/.yubico”

I verified the file contents

sudo cd /var/root/.yubico/
ls -al

Output

Text Output:

> drwxr-xr-x 4 root wheel 128 9 Oct 09:50 .
> drwxr-x— 12 root wheel 384 9 Oct 09:39 ..
> -rw-r–r– 1 root wheel 244 9 Oct 09:50 challenge-#######
> -rw-r–r– 1 root wheel 244 9 Oct 09:42 challenge-#######

Snip from: https://www.yubico.com/wp-content/uploads/2016/07/yubico_YubiKeyMacLoginGuide_en.pdf

“Program at least two YubiKeys when implementing a requirement for authentication with a YubiKey on your Mac. If you configure only one YubiKey and something happens to the YubiKey, you must restore the Mac from a Time Machine backup that you created before editing the authorization file before you can log back in to your account. ”

Reading the guide regarding multiple accounts (setting up a Key for each login). I have 5 logins on my Mac but when this works I will disable the other accounts from logging in.

Enable the use of the Yubico key when the screensaver is deactivated on macOS

I opened a terminal and edited “/etc/pam.d/screensaver ” (I use the easier nano editor)

sudo nano /etc/pam.d/screensaver

I added this line

auth       required       /usr/local/lib/security/pam_yubico.so mode=challenge-response

auth[7 spaces]required[7 spaces]/usr/local/lib/security/pam_yubico.so mode=challenge-response

I saved the file ( [CTRL+O], [CTRL+X] ) and exited nano.

I tested my screensaver and no extra protection was provided (the screensaver just exited).

I rebooted, still no change?

I reinstalled the PAM module.

Silly me, I needed to enable the password on the screensaver to then activate the /etc/pam.d/screensaver entries.

I enabled the screensaver passwords

I am now prompted to enter my password and inset and tap my Yubico Key on screensaver exit (on both keys). Awesome.

Next, I need to enable this at macOS login.

Enable the use of the Yubico key at macOS Login

I edited /etc/pam.d/authorization file with nano in the terminal

sudo nano /etc/pam.d/authorization

I added the same line as was added to the file /etc/pam.d/screensaver

auth       required       /usr/local/lib/security/pam_yubico.so mode=challenge-response

auth[7 spaces]required[7 spaces]/usr/local/lib/security/pam_yubico.so mode=challenge-response

I saved the file ( [CTRL+O], [CTRL+X] ) and exited nano.

Now let’s log out and test this.

It’s working.

Excellent

Add Two Factor Authentication to 1Password

Here is a guide on using the Yubico YubiKey with 1Password. This directed me to https://support.1password.com/yubikey/

I downloaded the Yubico Authenticator app on macOS and installed it.

After I inserted my primary Key I received a “No Credentials Found”message.

I logged into https://my.1password.com/signin and clicked My Profile.

I clicked More Actions then Turn On Two-Factor Authentication

I added the generated QR code details to the Android Authenticator and macOS Yubico Authenticator app. At first, I could not scan the QR code in macOS (was Mojave blocking this?), I manually entered the details (after confirming them from the Android app QR code scan).

Details:

Issuer: 1Password
Account Name: my.1password.com
Secret Key: ###################
Time: 30
Algorithm: SHA-1
Period: 30
Digits: 6

Now, 1Password web and the desktop app are asking for the 2-factor code (generated in the Yubico Authenticator app after I insert my YubioKey).

Nice

I logged off and I was not prompted for my Two Factor code?

Snip from: https://support.1password.com/two-factor-authentication/

“Your 1Password account is now protected by two-factor authentication. From now on, you’ll need to enter a six-digit authentication code from your authenticator app when you sign in to 1Password on a new device.”

I logged in to 1Password from Google Chrome on Android and indeed I was prompted for a two-factor auth code form the Yubico Authenticator app (with a KubiKey inserted).

Add Two Factor Authentication to Dropbox
I read https://www.yubico.com/works-with-yubikey/catalog/dropbox-personal/. Dropbox also has setup instructions here.

I logged into Dropbox and went to Settings then Security then clicked Add next to Security Keys

I started the Wizard, entered my Dropbox password, then inserted my YubiKey.

Name the Key

I added my Primary and Backup Key(s)

I logged out and back in and no Security Key prompt?

I am using Chrome and had cleared past browsers from the Dropbox list of web browsers at https://www.dropbox.com/account/security

I discovered that I need to set the primary authentication method to Use Mobile App (My Bad, it would be nice if Dropbox set this as default after I added the keys).

I added the Dropbox QR code to the Yuboico Authenticator app

I was asked to enter a 6 digit code from my Yubico Authenticator app to verify the working link. I inserted my YubiKey into my machine to show the code.

Now Dropbox is configured 🙂

Success

I now have to insert my primary key when logging into Dropbox

I need to find a way to copy my Authenticator credentials to my Backup Key from my Primary key

Add Two Factor Authentication to Twitter

I read https://www.yubico.com/works-with-yubikey/catalog/twitter/ (Setup Instructions)

1) Login to Twitter

2) Open your Settings and Look For Security

3) Click Start

4) Enter Your Password

5) Accept and enter any SMS codes if you set up SMS Two Factor codes via SMS

6) Click “Review your login verification methods”

7) Click “Setup Key”

8) Insert Your YubiKey and follow the prompts to activate it.

9) Now the key will be requoted to log in to Twitter

Testing Two Factor Login to Twitter

I logged out of and back into Twitter but the SMS Two Factor Authentication method was still active?

I tried to disable the SMS method in Twitter but two factor was disabled altogether and the registered key was deleted. I re-added my key 🙁

I solved this by choosing “Choose a different verification method” when logging in then choosing “Use your security key“, Twitter then accessed my YubiKey and further login attempts used the key instead of SMS 🙂 I could use an Authenticator code but they YubiKey touch method is quicker.

Done

It would be nice if Twitter allowed multiple keys to be used to log in?

Add Two Factor Authentication to Google, Google cloud, Gsuite etc

I read https://www.yubico.com/works-with-yubikey/catalog/google-accounts (Instructions https://myaccount.google.com/).

Adding two Factor authentication details to Google was not easily accessible at Google so I Googled (lol) this https://support.yubico.com/support/solutions/articles/15000006418-using-your-yubikey-with-google

I loaded: https://myaccount.google.com/signinoptions/two-step-verification/enroll-welcome

I clicked Get Start

I clicked Choose Another Option (not SMS Two factor)

Clicked Security Key

As prompted I inserted my key and allowed access to it.

I named the Key

I repeated the steps and added my 2nd key.

Done

I logged out my https://myaccount.google.com and logged back in and I was prompted to insert my YubiKey

Nice

I did try and login to my google GSuite account at https://admin.google.com but it did not prompt me to insert a key. I will do this next.

Add Two Factor Authentication to GSuite

I logged into the GSuite admin interface at https://admin.google.com/ I generated some backup codes in case I need them in the future.

I checked my main admin user account and I could see the 2 google security keys synced through from Google.

I then searched GSuite for “Two Factor” and loaded the “Enforcement” Page

I enabled “Turn On Enforcement Now”

I enabled “Only Security Keys”

I logged out and back into https://gsuite.google.com/ TWICE and no security key prompt.

Silly me: I forgot to click save at the bottom of the screen and it appears there is a 24-hour delay?

Add Two Factor Authentication to GMail

This is already done (above), GSuite email takes up to 24 hours to become active, GMail is instant.

Add Two Factor Authentication to Google Analytics

I can’t see an option to turn Two Factor Auth on in Google Analytics 🙂

I did send feedback to the Google Analytics team.

Add Two Factor Authentication to Google Adsense

I can’t see an option to turn Two Factor Auth on in Google Adsense either 🙂

I did send feedback to the Google AdSense team.

Add Two Factor Authentication to Github

I logged into Github, opened my Settings and clicked Security then Enable two-factor authentication

Click Setup using an app save the recovery codes.

Open the Yubico Authenticator app (ensure you can see the QR Code in GitHub)

In the Yubico Authenticator, App click File then Scan QR Code

The GitHub details should be added to the Authenticator

Two Factor via authenticator tokens is enabled and now I can see a Keys options,

I clicked Add next to security keys then Register New Device, I gave the key a name then clicked Add.

I added both keys then I Logged out and back in and two factor was enabled by YubiKey 🙂

Telstra promised Fibre to the house (FTTP) when I had FTTN and this is what happened..

July 28, 2018 by Simon

This post is for Telstra (to help a 10+-week investigation into Telstra NBN issues).

This post has been split up to make this page load faster: Read [Part 1] [Part 2] [Part 3] [Part 4] [Part 5]

Unresolved Issues with Telstra

Telstra promised Fibre to the premises but delivered fibre to the node (deceptive bait and switch?)
Data stability issues remain.

Status

TIO deadline (16th of August) passed 7 days ago (no resolution). Still waiting for assistance for the TIO (at least 6-week wait from the TIO ticket creation)
Telstra deadline passed (23rd August) with no resolution.
Escalating Federally (Federal cannot help until the TIO case is closed, Telstra will not close TIO case)
Telstra added a 2-week deadline to transfer the phone line (phone line back).
Have I been blacklisted by Telstra 13 22 00 support number (and reps says talk to your case manager)
Data stability issues remain

I was already with NBN (FTTN, ISP Name redacted) on a 50/20 Megabit plan and Telstra promised fibre to the house (FTTP) instead of FTTN and this is what happened (still unfolding…).

Telstra NBN (FTTN)

You can read my change over from ADSL 2 to NBN posts here. I was paying for a 50 Megabit Down and 20 Megabit up plan and it was not very after 5 months. I am not into torrenting unless downloading essential Raspberry Pi images or Linux ISO images. I needed a faster and more reliable internet connection and phone line.

My landline was down for 30 days and because I had a stroke recently (all good touch wood) a working phone line is very important. My previous provider said they can’t escalate issues unless the data line is completely down. Some days the internet was fine other days it was terrible.

I was sent a number of routers from my previous ISP to try an diagnose the dead landline and bad NBN speeds.

I was sick of the poor speeds of FTTN NBN. I was frequently talking to my previous NBN provider and had to perform daily router reboots. Some days NBN 50 Megabit seemed like being on a modem on a good day or ADSL1 on a bad day.

All support calls with my previous ISP support usually went one of two ways

We cannot escalate this issue (dead landline/slow data speeds) to NBN because your router is “syncing” (all be it slowly and with a dead landline).
We will send you a new router (mostly with experimental firmware?).

The landline stopped working and we got used to rebooting the router multiple times a day.

NBN is having troubles?

NBN woes signal boom in fixed wireless broadband internet (1 in l 6 NBN connections fail.

I was left thinking that I was being offered fibre to the house (FTTP – fibre laid up my driveway).

Telstra promise of Fibre (FTTN)?

Street to the house cabling (Fibre).

Fibre to the house sounds awesome.

Exiting my contact with my previous ISP

I asked my previous ISP to release me from the contract I was in (given the ongoing issues)

My previous ISP called and said that I can leave the contract 🙂

2nd Telstra Inquiry (and switchover to FTTN)

On the 3rd of July 2018, I contacted Telstra Chat to confirm fibre again and to switch over if it was fibre.

Upgraded to Wordfence Premium to get real-time login defence, malware scanner and two-factor authentication for WordPress logins

July 23, 2018 by Simon

This is a quick post that shows how I upgraded to Wordfence Premium to get real-time defence feeds, malware scanner and two-factor authentication for WordPress logins

Aside

If you have not read my previous posts I have now moved my blog to the awesome UpCloud host (signup using this link to get $25 free UpCloud VM credit). I compared Digital Ocean, Vultr and UpCloud Disk IO here and UpCloud came out on top by a long way (read the blog post here). Here is my blog post on moving from Vultr to UpCloud.

Buy a domain name here

Now on with the post.

What is Wordfence

WordFence is a free WordPress plugin (install guide here) that helps protect your WordPress site by logging and blocking bad events. I was a big fan of the Wordfence sister program called GravityScan (before it was retired)

Read my review of the free Wordfence plugin here.

I was using Wordfence free to

Whitelist logins for known IP’s (read my guide on whitelisting IPs here)
Block known bad IPs from the Wordfence global network (but with a 30-day delay)
Create a firewall
Rate limiting page requests
Scan my site for malware
Ability to see past failed logins (and ban them)
Ability to block/ban users who try and login form new IP’s
Force strong WordPress account passwords
Set ban thresholds
Have I Been Pwned breached password checks
Much more

Install and set up Wordfence (Free)

Read my guide here to learn how to setup Wordfence (Free).

Malware Infections

Your website is often scanned and ranked for safety by sites like Norton Safe Web, Google, Trend Micro, Kaspersky Virus Desk, SiteGuarding etc along with search engines. Having malicious files on your site will affect your site Search EnginOptimizationio (SEO).

I had a 5-year-old scan of a subdomain (that was hosted on a CPanel Host). The subdomain had false positives for malware.

Working to remove the false positive was a lengthy process.

You should aim to stay off the radar or many site scanning, check VirusTotal often to keep your self-updated as to the status of your website. Wordfence will hopefully detect real malware issues automatically in the future.

https://sitecheck.sucuri.net/ is a good site that can aggregate your sites safety ratings.

WordfFence Free v Premium

Prices (USD)

WordFence Premium

Read about some benefits of Wordfence Premium here.

Real-time firewall rules and malware signatures
Global Wordfence premium IP blacklist
Priority server processing for premium customers
Two Factor Authentication (only if you don’t use whitelisting I found out)

Buying a Wordfence Premium API Key

Login to https://www.wordfence.com/dashboard/
Click Buy More API Keys
Enter your Payment Details

>Thanks, your card information has been updated. You can now go to your API Key Manager and create and manage your Wordfence API keys.

Now you can buy an API key and copy and paste the API ey o to your Wordfence plugin.

Wordfence Firewall

Wordfence does a great job at showing failed/successful, top blocked IP’s

Wordfence Malware Scanner

Wordfence premium has schedulable scans with real-time malware signatures

Scan Progress

Testing the scanner

Wordfence says “A Wordfence scan examines all files on your WordPress website looking for malicious code, backdoors, shells that hackers have installed, known malicious URLs and known patterns of infections.”

I created an eicar.txt test file (information on eicar here (slightly modified so I don’t get tagged again b virus scanners)) to test the Wordfence malware scanner

echo 'X5O!P#removed#X54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*' > /www-root/eicar.txt
sudo chown www-data:www-data eicar.txt

I enable scanning of files outside of WordPress

I rescanned my site with Wordfence

Result: Nothing??

I logged a support ticket to see if this is right?

Update: Wordfence support replied and said “Thanks for writing in. We do detect the EICAR test file, but scans don’t scan file types that aren’t dangerous on a site by default, since scans would waste a lot of time on files that aren’t exploitable.“

I disagree a virus is a virus.

Wordfence says “A Wordfence scan examines all files on your WordPress website looking for malicious code, backdoors, shells that hackers have installed, known malicious URLs and known patterns of infections.”

I guess “all” does not mean “all”?

Wordfence support said EICAR files are detected if I rename the file to php. I renamed the file and to enabled “Scan images, binary, and other files as if they were executable“.

I started a new scan

> Scan Failed
>The scan has failed because we received an unexpected response from the Wordfence servers. This may be a temporary error, though some sites may need adjustments to run scans reliably

🙁

I scanned my system with ClamAV and it found the EICAR file.

clamscan -r --bell -i /www-root

Result:

/www-root/eicar.txt: Eicar-Test-Signature FOUND

ClamAV found the virus.

Setting up Two Factor Authentication (work in progress)

Add your desired user and number

Click Enable User

Wait for the text message and activation code (on your phone)

Enter the activation code and press Activate

The two-factor authentication should be activated

List of two-factor authorization enabled users.

I logged out of WordPress and logged back in but the two-factor auth did not work, I logged a support Ticket with my theme maker and WordFence.

Update: Wordfence Support “Wordfence > Tools > Two Factor Authentication options there is an option for Enable Separate Prompt for Two Factor Code which you could disable and try.“

This fix did not work. I sent a 2nd diagnostics report to Wordfence.

Wordfence support said

>When our two-factor authentication feature allows you to login bypassing the need to enter the authentication code it is typically because of these possible reasons:

> 1) The user has whitelisted their IP address in the advanced firewall option “Whitelisted IP addresses that bypass all rules“.

>2) Another plugin, or possibly a theme, that creates non-standard WordPress behaviour such as user role and capabilities modification, or that modifies the login flow process in some way.

It appears my IP whitelist was disabling the two-factor auth feature 🙁

I’d rather keep the two-factor auth along with keeping the whitelist (just in case my whitelist IP is known and used).

Refund

I asked Wordfence for a refund (given)

Conclusion

Pros

Protects and blocks bad logins
Real-time blocked IP and malware feeds

Cons

Almost $140 Australian dollars a year
A scan does not detect eicar.txt test virus files (ticked logged), renamed to eicar.php and still no luck.
Two-factor auth (authenticator and SMS) does not work (ticket logged)
Wordfence support resolve/close support tickets with no confirmation from the user.
Two Factor Auth is disabled if you whitelist IPs 🙁

Is Premium worth it? Yes if you want “Real-time firewall rules and malware signatures” (and don’t whitelist your IP).

I hope this guide helps someone.

Setup a dedicated Debian subdomain (VM), Install MySQL 14 and connect to it from a WordPress on a different VM

July 21, 2018 by Simon

This is how I set up a dedicated Debian subdomain (VM), Installed MySQL 14 and connected to it from a WordPress installation on a different VM

Aside

Buy a domain name here

Now on with the post.

Fearby.com

I will be honest, fearby.com is my play server where I can code, learn about InfoSec and share (It’s also my stroke rehab blog).

There is no faster way to learn than actually doing. The problem is my “doing” usually breaks the live site from time to time (sorry).

I really need to set up a testing environment (DEV-TEST-LIVE or GREEN-BLUE) server(s). GREEN-BLUE has advantages as I can always have a hot spare ready. All I need to do is toggle DNS and I can set the GREEN or BLUE server as the live server.

But first I need to separate my database from my current fearby.com server and setup up a new web server. Having a Green and Blue server that uses one database server will help with near real-time production website switches.

Dedicated Database Server

I read the following ( Should MySQL and Web Server share the same server? ) at Percona Database Performance Blog. Having a separate database server should not negatively impact performance (It may even help improve speeds).

Deploy a Debian VM (not Ubuntu)

I decided to set up a Debian server instead of Ubuntu (mostly because of the good focus on stability and focus on security within Debian).

I logged into the UpCloud dashboard on my mobile phone and deployed a Debian server in 5 mins. I will be using my existing how to setup Ubuntu on UpCloud guide (even though this is Debian).

TIP: Sign up to UpCloud using this link to get $25 free UpCloud VM credit.

Deploy a Debian server setup steps:

Login to UpCloud and go to Create server.
Name your Server (use a fully qualified domain name)
Add a description.
Choose your data centre (Chicago for me)
Choose the server specs (1x CPU, 50GB Disk, 2GB Memory, 2TB Traffic for me)
Name the Primary disk
Choose an operating system (Debian for me)
Select an SSH Key
Choose misc settings
Click Deploy server

After 5 mins your server should be deployed.

After Deploy

Setup DNS

Login to your DNS provider and create DNS records to the new IP’s (IPv4 and IPv6) provided by UpCloud. It took DNS 12 hours to replicate to my in Australia.

Setup a Firewall (at UpCloud)

I would recommend you set up a firewall at UpCloud as soon as possible (don’t forget to add the recommended UpCloud DNS IP’s and any whitelisted IP’s your firewall).

Block everything and only allow

Port 22: Allow known IP(s) of your ISP or VPN.
Port 53: Allow known UpCloud DNS servers
Port 80 (ALL)
Port 443 (ALL)
Port 3306 Allow your WordPress site and known IP(s) of your ISP or VPN.

Read my post on setting up a whitelisted IP on an UpCloud VM… as it is a good idea.

UpCloud thankfully has a copy firewall feature that is very handy.

After I set up the firewall I SSH’ed into my server (I use vSSH on OSX buy you could use PUTTY).

I updated the Debian system with the following command

sudo apt update

Get the MySQL Package

Visit http://repo.mysql.com/ and get the URL of the latest apt-config repo deb file (e.g “mysql-apt-config_0.8.9-1_all.deb”). Make a temp folder.

mkdir /temp
cd /temp

Download the MySQL deb Package

wget http://repo.mysql.com/mysql-apt-config_0.8.9-1_all.deb

Install the package

sudo dpkg -i mysql-apt-config_0.8.9-1_all.deb

Update the system again

sudo apt update

Secure MySQL

You can secure the MySQL server deployment (set options as needed)

sudo mysql_secure_installation

Enter password for user root:
********************************************
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: No
Using existing password for root.
Change the password for root ? ((Press y|Y for Yes, any other key for No) : No

... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have

testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Yes

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : No

... skipping.
By default, MySQL comes with a database named 'test' that

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Yes
Success.

All done!

Install NGINX

I installed NGINX to allow Adminer MySQL GUI to be used

I ran these commands to install NGINX.

sudo apt update
sudo apt upgrade
sudo apt-get install nginx

I edited my NGINX configuration as required.

Set a web server root
Set desired headers
Optimized NGINX (see past guides here, here and here)

I reloaded NGINX

sudo nginx -t
sudo nginx -s reload
sudo systemctl restart nginx

Install PHP

I followed this guide to install PHP on Debian.

sudo apt update
sudo apt upgrade

sudo apt install ca-certificates apt-transport-https
wget -q https://packages.sury.org/php/apt.gpg -O- | sudo apt-key add -
echo "deb https://packages.sury.org/php/ stretch main" | sudo tee /etc/apt/sources.list.d/php.list

sudo apt update
sudo apt install php7.2
sudo apt install php-pear php7.2-curl php7.2-dev php7.2-mbstring php7.2-zip php7.2-mysql php7.2-xml php7.2-cli php7.2-common

Install PHP FPM

apt-get install php7.2-fpm

Increase Upload Limits

You may need to temporarily increase upload limits in NGINX and PHP before you can restore a WordPress database. My feabry.com blog is about 87MB.

Add “client_max_body_size 100M;” to “/etc/nginx/nginx.conf”

Add the following to “/etc/php/7.2/fpm/php.ini”

post_max_size = 100M
upload_max_filesize = 100M

Restore a backup of my MySQL database in MySQL

You can now use Adminer to restore your blog to MySQL. Read my post here on Adminer here. I used Adminer to move my WordPress site from CPanel to a self-managed server a year ago.

First login to your source server and export your desired database then login to the target server and import the database.

Firewall Check

Don’t forget to allow your WordPress site’s 2x Public IP’s and 1x Private IP to access port 3306 in your UpCloud Firewall.

How to check open ports on your current server

sudo netstat -plunt

Set MySQL Permissions

Open MySQL

mysql --host=localhost --user=root --password=***************************************************************************

I ran these statements to grant the user logging in on the nominate IP’s access to MySQL.

mysql>
GRANT ALL ON databasenmae.* TO [email protected] IDENTIFIED BY '***********sql*user*password*************';
GRANT ALL ON databasenmae.* TO [email protected] IDENTIFIED BY '***********sql*user*password*************';
GRANT ALL ON databasenmae.* TO [email protected] IDENTIFIED BY '***********sql*user*password*************';
GRANT ALL ON databasenmae.* TO [email protected] IDENTIFIED BY '***********sql*user*password*************';

Reload permissions in MySQL

FLUSH PRIVILEGES;

Allow access to the Debian machine from known IP’s

Edit “/etc/host.allow”

Additions (known safe IP’s that need access to this MySQL remotely).

mysqld : IPv4Server1PublicAddress : allow
mysqld : IPv4Server1PrivateAddress : allow
mysqld : IPv4Server2PublicAddress : allow
mysqld : IPv4Server1PrivateAddress : allow

mysqld : ALL : deny

Tell MySQL to listen on

Edit “/etc/mysql/my.cnf”

Added..

[mysqld]
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
language = /usr/share/mysql/English
bind-address = DebianServersIntenalIPv4Address

I guess you could change the port to something random???

Restart MySQL

sudo service mysql restart

Install a second local firewall on Debian

Install ufw

sudo apt-get instal ufw

Do add the IP of your desired server or VPN to access SSH

sudo ufw allow from 123.123.123.123 to any port 22

Do add the IP of your desired server or VPN to access WWW

sudo ufw allow from 123.123.123.123 to any port 80

Now add the known IP’s (e.g any web servers public (IPv4/IPv6) or Private IP’s) that you wish to grant access to MySQL (e.g the source website that used to have MySQL)

sudo ufw allow from 123.123.123.123 to any port 3306

Do add UpCloud DNS Servers to your firewall

sudo ufw allow from 94.237.127.9 to any port 53
sudo ufw allow from 94.237.40.9 to any port 53
sudo ufw allow from 2a04:3544:53::1 to any port 53
sudo ufw allow from 2a04:3540:53::1 to any port 53

Add all other rules as needed (if you stuff up and lock your self out you can login to the server with the Console on UpCloud)

Restart the ufw firewall

sudo ufw disable
sudo ufw enable

Prevent MySQL starting on the source server

Now we can shut down MySQL on the source server (leave it there just in case).

Edit “/etc/init/mysql.conf”

Comment out the line that contains “start on ” and save the file

and run

sudo systemctl disable mysql

Reboot

shutdown -r now

Stop and Disable NGINX on the new DB server

We don’t need NGINX running now the database has been imported with Adminer.

Stop and prevent NGINX from starting up on startup.

/etc/init.d/nginx stop
sudo update-rc.d -f nginx disable
sudo systemctl disable nginx

Check to see if MySQL is Disabled

service mysql status
* mysql.service - MySQL Community Server
Loaded: loaded (/lib/systemd/system/mysql.service; disabled; vendor preset: enabled)
Active: inactive (dead)

Yep

Test access to the database server in PHP code

Add to dbtest.php

<em>SELECT guid FROM wp_posts</em>()<br />
<ul><?php

//External IP (charged after quota hit)
//$servername = 'db.yourserver.com';

//Private IP (free)
//$servername = '10.x.x.x';

$username = 'username';
$password = '********your*password*********';
$dbname = 'database';

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = 'SELECT guid FROM wp_posts';
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo $row["guid"] . "<br>";
    }
} else {
    echo "0 results";
}
$conn->close();
?></ul>
Done

Check for open ports.

You can install nmap on another server and scan for open ports

Install nmap

sudo apt-get install nmap

Scan a server for open ports with nmap

You should see this on a server that has access to see port 3306 (port 3306 should not be visible by non-whitelisted IP’s). Port 3shouldoudl not be seen via everyone.

sudo nmap -PN db.yourserver.com

Starting Nmap 7.40 ( https://nmap.org ) at 2018-07-20 14:15 UTC
Nmap scan report for db.yourserver.com (IPv4IP)
Host is up (0.0000070s latency).
Other addresses for db.yourserver.com (not scanned): IPv6IP
Not shown: 997 closed ports
PORT     STATE SERVICE
3306/tcp open  mysql

You should see something like this on a server that has access to see port 80/443 (a web server)

sudo nmap -PN yourserver.com

Starting Nmap 7.40 ( https://nmap.org ) at 2018-07-20 14:18 UTC
Nmap scan report for db.yourserver.com (IPv4IP)
Host is up (0.0000070s latency).
Other addresses for db.yourserver.com (not scanned): IPv6IP
Not shown: 997 closed ports
PORT     STATE SERVICE
80/tcp   open  http
443/tcp   open  https

I’d recommend you use a service like https://pentest-tools.com/network-vulnerability-scanning/tcp-port-scanner-online-nmap# to check for open ports. https://hackertarget.com/tcp-port-scan/ is a great tool too.

https://www.infobyip.com/tcpportchecker.php is also a free port checker that you can use to verify individual closed ports.

Hardening MySQL and Debian

Read: https://www.debian.org/doc/manuals/securing-debian-howto/ap-checklist.en.html

Configuring WordPress use the dedicated Debian VM

On the source server that used to have MySQL edit your wp-config.php file for WordPress.

Remove

define('DB_HOST', 'localhost');

add (read the update below, I changed the DNS IP to the Private IP to have free traffic)

//Oriinal localhost
//define('DB_HOST', 'localhost');

//New external host via DNS (Charged after quota hit)
//define('DB_HOST', 'db.fearby.com');

//New external host via Private IP (Free)
define('DB_HOST','10.x.x.x');

Restart NGINX

sudo nginx -t
sudo nginx -s reload
sudo systemctl restart nginx

Restart PHP-FPM

service php7.2-fpm restart

Conclusion

Nice, I seem to have shaved off 0.3 seconds in load times (25% improvement)

Update: Using a Private IP or Public IP between WordPress and MySQL servers

After I released this blog post (version 1.0 with no help from UpCloud) UpCloud contacted me and said the following.

Hello Simon,

I notice there's no mention of using the private network IPs. Did you know that we automagically assign you one when you deploy with our templates. The private network works out of the box without additional configuration, you can use that communicate between your own cloud servers and even across datacentres.

There's no bandwidth charge when communicating over private network, they do not go through public internet as well. With this, you can easily build high redundant setups.

Let me know if you have any other questions.

--
Kelvin from UpCloud

I will have updated my references in this post and replace the public IP address (that is linked to DNS record for db.fearby.com) and instead use the private ip address (e.g 10.x.x.x), your servers private IP address is listed against the public IPv$ and IPv6 address.

I checked that the local ufw firewall did indeed allow the private IP access to MySQL.

sudo ufw status numbered |grep 10.x.x.x
[27] 3306                       ALLOW IN    10.x.x.x

On my new Debian MySQL server, I edited the file /etc/mysql/my.cnf and changed the IP to the private IP and not the public IP.

Now it looked like

[mysqld]
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
language        = /usr/share/mysql/English
bind-address    = 10.x.x.x

(10.x.x.x my Debian servers private IP)

On my WordPress instance, I edited the file /www-root/wp-config.php

I added the new private host

//Oriinal localhost
//define('DB_HOST', 'localhost');

//New external host via DNS (Charged after quota hit)
//define('DB_HOST', 'db.fearby.com');

//New external host via Private IP (Free)
define('DB_HOST','10.x.x.x');

(10.x.x.x my Debian servers private IP)

Alos on Debian/MySQL ensure you have granted access to the private IP of the WordPress server

Edit /etc/host.allow

Add

mysqld : 10.x.x.x : allow

Restart MySQL

sudo systemctl restart mysql

TIP: Enable UpCloud Backups

Do setup automatic backups (and or take manual backups). Backups are an extra charge but are essential IMHO.

Troubleshooting

If you can’t access MySQL log back into MySQL

mysql --host=localhost --user=root --password=***************************************************************************

and run

GRANT ALL PRIVILEGES ON *.* TO [email protected]'%' IDENTIFIED BY '***********sql*user*password*************''; FLUSH PRIVILEGES;

Reboot

Lower Upload Limits

Don’t forget to lower file upload sizes in NGINX and PHP (e.g 2M) now that the database has been restored.

I hope this guide helps someone.

v1.0 Initial Post

Adding two sub domains (one pointing to a new UpCloud VM and the other pointing to an NGINX subsite) on Ubuntu 18.04

June 27, 2018 by Simon

Here is how I added two subdomains (one pointing to a new UpCloud VM and the other pointing to an NGINX subsite) on Ubuntu 18.04

If you have not read my previous posts I have now moved my blog to the awesome UpCloud host (signup using this link to get $25 free credit). I compared Digital Ocean, Vultr and UpCloud Disk IO here and UpCloud came out on top by a long way (read the blog post here). Here is my blog post on moving from Vultr to UpCloud.

UpCloud performance is great.

Buy a domain name from Namecheap here.

Goal(s)

Setup 2x subdomains on https://fearby.com

– Sub Domain #1: https://test.fearby.com (pointing to a dedicated UpCloud VM in Singapore for testing).

– Sub Domain #2: https://audit.fearby.com (pointing to a sub-website on the NGINX/VM that runs https://fearby.com )

Let’s set up the first Sub Domain (dedicated VM) and SSL

Backup

Do backup your server first.

I created a second server ($5 month or $0.07c hour 1,024MB Memory, 25GB Disk, 1024 GB Month Data Transfer) at UpCloud. If you don’t already have an account at UpCloud use this link to signup and get $25 free credit ( https://www.upcloud.com/register/?promo=D84793 ). Read my blog post on why UpCloud is awesome and how I moved my domain to UpCloud.

Once I spun up a second server I obtained the IPv4 and IPv6 IP addresses of the new “test” VM from the UpCloud dashboard.

IPV4 IP: 94.237.65.54
IPV6 IP: 2a04:3543:1000:2310:24b7:7cff:fe92:468c

DNS

These DNS records were already in place with my DNS provider (Cloudflare).

A fearby.com 209.50.48.88
AAAA fearby.com 2605:7380:1000:1310:24b7:7cff:fe92:0d64

I added these DNS records for the subdomains.

I added a new A NAME record for the new shared NGINX subdomain (for https://audit.fearby.com), this subdomain will be a sub-website that is running off the same server as https://fearby.com

A audit 209.50.48.88
AAAA audit 2605:7380:1000:1310:24b7:7cff:fe92:0d64

I added another set of records for the new dedicated VM subdomain (for https://test.fearby.com)

A test 94.237.65.54
AAAA test 2a04:3543:1000:2310:24b7:7cff:fe92:468c

I waited for DNS to replicate around the globe by watching https://www.whatsmydns.net/

Setup a Firewall

On the new dedicated https://test.fearby.com VM, I installed the ufw firewall.

sudo apt-get install ufw

I configured the firewall to allow minimum ports (and added whitelisted IP for port 22 and added UpCloud DNS servers). I will lock this down some more later.

TIP: If your ISP does not offer a dedicated IP try a VPN. I use https://cyberghostvpn.com on OSX and Android.

Firewall rules.

sudo ufw status numbered

[12] 25 (v6)                    DENY IN     Anywhere (v6)

I enabled the firewall.

sudo ufw enable

sudo ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/default

Lets Encrypt SSL

I have previously setup Lets encrypt on Ubuntu 16.04 but not 18.04. Certbot had info on setting up Lets Encrypt for 14.x 16.x and 17.x but not 18.x

Full credit for the SSL steps goes to @Linuxize ( tips on setting up Lets Encrypt on Ubuntu 18.04 ). Check out https://linuxize.com/

I installed Lets Encrypt certbot

Let’s get a certificate

sudo certbot certonly --agree-tos --email [email protected] --webroot -w /var/lib/letsencrypt/ -d test.fearby.com

Certificates have been created 🙂

ls -al /etc/letsencrypt/live/test.fearby.com/

drwxr-xr-x 2 user user 4096 Jun 26 11:30 .

lrwxrwxrwx 1 user user   42 Jun 26 11:30 privkey.pem -> ../../archive/test.fearby.com/privkey1.pem

Now lets edit “/etc/nginx/sites-available/default” on https://test.fearby.com VM and add the cert paths.

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        listen 443 ssl http2;
        listen [::]:443 ssl http2;

        if ($scheme != "https") {
                return 301 https://$host$request_uri;
        }

        ssl_certificate /etc/letsencrypt/live/test.fearby.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/test.fearby.com/privkey.pem;
        ssl_trusted_certificate /etc/letsencrypt/live/test.fearby.com/chain.pem;

        include snippets/ssl.conf;

        #ssl_stapling on; # Requires nginx >= 1.3.7
        # add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";

        add_header X-Frame-Options DENY;
        add_header X-Content-Type-Options nosniff;
        add_header X-XSS-Protection "1; mode=block";

        root /www-root/;

        include snippets/letsencrypt.conf;

        index index.html;

        server_name test.fearby.com;

        location / {
                try_files $uri $uri/ =404;
        }
}

Reload NGINX

sudo systemctl reload nginx

sudo nginx -t
sudo nginx -s reload
sudo systemctl reload nginx

Now let’s setup the second subdomain (subsite off https://fearby.com) and SSL

I already have NGINX on https://fearby.com set up a second site.

DNS

We have already setup a DNS record for https://audit.fearby.com (above)

Firewall

Already configured at https://fearby.com

SSL

Because I had an existing Comodo certificate on https://fearby.com I am going to repeat the steps above to generate a new certificate but save the NGINX config to /etc/nginx/sites-available/audit.fearby.com (this activates the second site)

TIP: Follow the Linuxize guide here (for creating ssl.conf, letsencrypt.conf etc config files), Do a backup and restore if need be.

I created a new Diffie–Hellman key

mkdir -p /etc/ssl/certs/
sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

Let’s get a certificate

sudo certbot certonly --agree-tos --email [email protected] --webroot -w /var/lib/letsencrypt/ -d audit.fearby.com

Configure NGINX

Map requests to http://audit.fearby.com/.well-known/acme-challenge to /var/lib/letsencrypt/.well-known ( Read the linuxize post for detailed steps ).

mkdir -p /var/lib/letsencrypt/.well-known
chgrp www-data /var/lib/letsencrypt
chmod g+s /var/lib/letsencrypt

I created a new NGINX site ( /etc/nginx/sites-available/audit.fearby.com )

#proxy_cache_path /tmp/nginx-cache keys_zone=one:10m;#
server {
        root /www-audit-root;

        # Listen Ports
        listen 80;
        listen [::]:80;
        listen 443 ssl http2;
        listen [::]:443 ssl http2;

        # Default File
        index index.html index.php index.htm;

        # Server Name
        server_name audit.fearby.com;

        include snippets/letsencrypt.conf;

        location / {
                try_files $uri $uri/ =404;
        }

        ssl_certificate /etc/letsencrypt/live/audit.fearby.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/audit.fearby.com/privkey.pem;
        ssl_trusted_certificate /etc/letsencrypt/live/audit.fearby.com/chain.pem;

        ssl_dhparam /etc/ssl/certs/auditdhparam.pem;

        ssl_session_timeout 1d;
        #ssl_session_cache shared:SSL:50m;
        ssl_session_tickets off;

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA38$

        ssl_prefer_server_ciphers on;

        ssl_stapling on;
        ssl_stapling_verify on;

        #resolver 8.8.8.8 8.8.4.4 valid=300s;
        #resolver_timeout 30s;

        add_header Strict-Transport-Security "max-age=15768000; includeSubdomains; preload";
        add_header X-Frame-Options SAMEORIGIN;
        add_header X-Content-Type-Options nosniff;

        if ($scheme != "https") {
                return 301 https://$host$request_uri;
        }
}

I created a symbolic link of the config file

sudo ln -s /etc/nginx/sites-available/audit.fearby.com /etc/nginx/sites-enabled/audit.fearby.com

Reload NGINX

sudo systemctl reload nginx

sudo nginx -t
sudo nginx -s reload
sudo systemctl reload nginx

How to test the certificate renewal

sudo certbot renew --dry-run

Automate the renewal in crontab (every 12 hours)

I set this crontab entry up on https://fearby.com and https://test.fearby.com

crontab -e
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew --renew-hook "systemctl reload nginx"

Conclusion

Yes, I haVe 2 subdomains (1x dedicated VM and the other is a sub-website off an existing server) with SSL certificates.

Troubleshooting

If you are having troubles generating the initial certificate check that you have not blocked port 80 and don’t have “Strict-Transport-Security” heavers enabled.

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: yoursubdomain.domain.com
   Type:   unauthorized
   Detail: Invalid response from
   http://yoursubdomain.domain.com/.well-known/acme-challenge/_QA3jblEydx5mE8I8OdRsd2EdHIj4R-przLlmg_w6Tc:

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address.

I re-ran the certbot command but pointed to the real /www-root (not/var/lib/letsencrypt/)

Create a new

mkdir /www-root/.well-known/
mkdir /www-root/.well-known/acme-challenge/
sudo certbot certonly --agree-tos --email [email protected] --webroot -w /www-root -d yoursubdomain.domain.com
