CentOS 6/7 IPSec/L2TP VPN client to UniFi USG L2TP Server

Working with CentOS quite a lot I have spent time looking for configurations that work for various issues, one I have seen recently that took me a long time to resolve and had very poor documentation around the net was setting up an L2TP VPN.

In Windows or iOS its a nice simple setup where you enter all the required details and it sorts out the IPsec and L2TP VPN for you, In CentOS this is much different.

Mikrotik OpenVPN Server with Linux Client

I spent quite some time trying to get the OpenVPN Server working on the Mikrotik Router with a Linux client, It caused some pain and I didnt want others to go through that. I have therefore written this guide, taking you from certificate creation all the way to VPN connectivity.

For this tutorial I will have SSH to my Mikrotik (you can use a winbox terminal), I have chosen not to use WinBox for the configuration as its easier to deploy this way.

Graylog2 CentOS Installation

I recently required a syslog server that was easy to use with a web interface to monitor some customers firewalls. I had been looking at Splunk but due to the price of this product it was not a viable option for what I required.

After a little searching I came across Graylog2 which is an open source alternative to Splunk and is totally free! You only need to pay if you would like support from them.

Teamspeak 3 with MySQL on CentOS 6.x (before 3.0.11.1)

NOTE: As of Version 3.0.11.1 this tutorial is no longer applicable. I will soon re-write this to accommodate the latest version.

By default Teamspeak 3 uses a SQLite database, most people tend to use this however for those of us that prefer MySQL there is a way to change it.

Follow this small tutorial to create a Teamspeak 3 Server on CentOS 6.x using a MySQL Database!
