How to get your MySQL Munin Graphs working

I run a few cPanel servers and run Munin as my resource monitor. At the time I wrote this the version included with cPanel was munin 1.24. Ever since I have installed the plugin from cPanel it would monitor MySQL upon first install and then stop if the server was reboot. Uninstalling and reinstalling would once again get Munin to monitor MySQL but having to uninstall and reinstall just for a reboot, just did not seem like something that you should have to do. After many months of on and off testing this is the fix I have come up with.

Automatic Proxy Configuration

WebDav Autoversioning

A while back I stumbled upon a lesser known feature of SVN and WebDav, but didn’t have the time to blog about it until now. WebDAV and SVN is an exceedingly useful tool as we all know, and pretty damn easy to setup, see here. But what if you could have everything entered into the WebDav repository automatically versioned into a repository. Well you can! And the good news is, it’s really really easy.

Make SSH connections with PHP

by 3 others
Not everyone knows about PHP's capabilities of making SSH connections and executing remote commands, but it can be very useful. I've been using it a lot in PHP CLI applications that I run from cronjobs, but initially it was a pain to get it to work. The PHP manual on Secure Shell2 Functions is not very practice or thorough for that matter, so I would like to share my knowledge in this how to, to make it a little less time consuming setting this up. In this article I'm going to assume that: * You're running Debian / Ubuntu If not, you will have to substitute the package manager aptitude with whatever your distribution provides * You're running PHP 5 If not, just replace php5 with php4 everywhere * You have basic knowledge of PHP & server administration * You already have PHP installed

SSH Port Forwarding

SSH also has a wonderful feature called SSH Port Forwarding, sometimes called SSH Tunneling, which allows you to establish a secure SSH session and then tunnel arbitrary TCP connections through it. Tunnels can be created at any time, with almost no effort and no programming, which makes them very appealing. In this article we look at SSH Port Forwarding in detail, as it is a very useful but often misunderstood technology. SSH Port Forwarding can be used for secure communications in a myriad of different ways. Let's start with an example.
