Sometimes you need to use a VPN connection to grant access to remote network resources and for that you use a VPN, but if you don’t want all of your client traffic to go through the VPN link, you’ll need to setup your VPN to connect in a “split tunnel” mode. Here’s how to do it on Ubuntu.

Many services and programs out there produce log files as an audit trail for everything they are doing, however few have a function which removes these files as they outlive their usefulness.

If you have been an admin for any length of time, you have certainly discovered situations where a server spikes in CPU use or memory utilization and/or load levels. Running `top` won’t always give you the answer, either. So how do you find those sneaky processes that are chewing up your system resources to be able to kill ‘em?
