Here is another one that you may find useful to do after a default install of probably any Linux server, Disabling extra stuff from loading at startup. Ubuntu loads a ton of them and many I do not use at all. Since when do you need joystick or sound support on a server anyway? Anyways, here are some I disable and how I disable them.
Continue readingOK, I promised a friend some time ago that I’d post all of my post-install procedures and I’ve not quite followed through with that so I’m doing a few before finishing up my three part post on the “Home Hacker’s Network”. These are all just little hacks I’ve come across and modified to suit my needs. I like this one a bunch as it gives me a nice shell prompt when I login as well as when I use screen (although the gnu screen configuration part is mutually exclusive to the shell modification part).
So lets get started…
Continue readingOn a headless server that you have at home or for testing I like to make sure that all security updates and trivial updates are done automatically. A good sys admin will shy away from this practice for a good reason, updates can mess things up. In a production environment or where the server setup is very complex I can understand the need to manually run updates. For me, well I’m lazy when it comes to my home machines and generally don’t have too complex of setups. Also, in my experience, I’ve hardly ever seen an apt security or trivial update cause any harm (desktop linux I have seen issues though). That being said, I like to force security and trivial updates to happen daily.

If you followed the first post in this series you are technically now ready to start loading up images and making labs of your own. You will need to get your hands on some IOS images (legally of course).But which IOS should you use?
Continue readingGNS3 is a frontend for dynagen (which is a scripting language for dynamips). Getting it to work nicely in Ubuntu was a bit of a pain in the arse but I was able to get it to work in a manner I’m happy with. This setup will essentially encapsulate a large portion of the install to one directory in /opt. Some libraries and executables will be installed through apt though, but not many. I previously wrote part of a writeup for this on Ubuntu 7.10, I’d ignore that in favor of this one which is much more up to date and polished.
