Previously I did a post on how to have some Fun With IPv6 Words, and how to generate an IPv6 word list, but one request I keep getting is for a smaller list of just the funny IPv6 words.
An Intro to DNS
I always find it amazing how little so many people in IT actually know about DNS. Well, today I’m going to give you a brief overview of the basics of DNS, the Domain Name System. We’ll call this, an “Intro to DNS!”
SSH Proxy Through Multiple Servers
Yesterday, a young pup at the pound asked me about hopping a proxy across multiple machines. Well, running a SOCKS5 proxy through multiple SSH servers isn’t all that hard, and can be fun at the same time! Today we will take a look at how to proxy through one or more SSH servers!
Fun With IPv6 Words!
If you have spent any time with IPv6 addresses, you may have realized that there are many different words that you can spell within an IPv6 address. So, let’s take a look at all the different IPv6 words we can spell!
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 […]
Blocking Services with Fail2Ban
There are many different methods of securing a publicly accessible server, and one of the best things a system administrator can do is use fail2ban to dynamically block potential attackers before they can do any damage.
Setting up an IPv6 Tunnel
So, you want to access IPv6 websites, but your ISP does not provide native IPv6 access? Well, here are some instructions for setting up a 6in4 IPv6 tunnel with Hurricane Electric!

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 […]
Radvd and DHCPd6 Server Configuration fo...
I’ve been using radvd for a while now to hand out IPv6 addresses to all the different devices in my Dogghouse, and I thought that it would be nice to have a working dynamic DNS setup for IPv6, in the same way as I have DDNS for IPv4.
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!
