udev renames you network interfaces
Sometimes udev renames your devices. This happened to me when upgrading a server, eth0 suddenly became eth1 and vice-versa. Of course, this broke nearly all firewall scripts on the server… There is a nice explanation how to get udev to name your devices the way you want.

VMWare Server on Ubuntu 8.04
A nice tutorial for getting free VMWare Server 1.0.5 running on Ubuntu 8.04.
As I definitely should post more on my blog, I now try to start a new series: “Nice to know”. It will be a collection of interesting things I consider memorable but which don’t deserve their own blog-post.
Tricke allows you to limit bandwith for processes that do not support bandwith limitation out-of-the-box. It works by preloading and simulating the socket API. You use it as a wrapper when starting the process, like trickle -d 80 someapp.
You can use it to limit rsync speed for instance (thanks to http://www.yak.net/fqa/404.html): rsync -auvPe “trickle -d 80 ssh” user@host:/src/ /dst/
VMWare Tools and Kernel 2.6.24
VMWare Tools out of the box do not install on kernel 2.6.24 (as used in Ubuntu 8.04 for instance). A possible solution is described here. It is based on using the open-source version of the VMWare tools (open-vm-tools).
By default, VMware Workstation 5.x use a memory mapped file for backing the RAM of the simulated machines. This eases the pressure on the system’s page file. If you host the virtual machine on an external drive, however, this can become a bottle neck, especially if the external device is slow (e.g. USB 1.1, flash, etc.).
As described in this VMware Knowledge Base Article, you can turn of VMWare’s behaviour to use a memory mapped file and force it to use the system’s paging mechanism instead. To do so, you just have to add
to your virtual machine’s configuration file (.vmx).
