Setting up HTB on CentOS 6

Setting up HTB on CentOS 6

The Hierarchical Token Bucket Quality of Service (HTB QoS) system is a great tool to use for controlling the bandwidth of a network link, especially when you have a bunch of doggs on your network that love to use up all the internets they can get! Lets take a look at a quick and simple […]

Installing PS3 Media Server on CentOS 6

Installing PS3 Media Server on CentOS 6

So after recently rebuilding one of the servers in my dogghouse, I realized that I hadn’t installed a uPNP/DLNA AV media server. Previously I had been using Fuppes, but the lack of active development and some other quirks made me re-think what I wanted to use. So, after comparing available packages, I decided to give […]

Lockd and Statd NFS Errors

Lockd and Statd NFS Errors

The other day, the NFS clients at the pound stopped working correctly. Programs that use a NFS share for caching data or locking files (such as Firefox) stopped working without any explanation. My doggs were also unable to compile any programs, which led to a lot of barking and growling from all of them!
