I need to run a few more Linux server securely, but haven’t got the extra machines to run it on. VMware tend to slow the virtual servers a bit too much, especially if you’re running a lot of it. So I started to look at [ User Mode Linux ] (UML).

To my surprise, if your existing server runs Debian stable (woody), and you have backports.org listed as one of its software repository, then installing UML is as easy as “apt-get install user-mode-linux”. Nice ! thanks to (I think) Matt Zimmerman for this. /usr/share/doc/user-mode-linux/README.Debian also has some extra pointers.

This will keep me busy for days for sure. I’ll post any UML-related tutorials here as soon as I have it ready. Stay tuned.

If you have been wishing to start learning to become a Linux sysadmin (system administrator), but has been put off by the requirements (need to boot to Linux: but VMware to expensive, setting up coLinux too hard for you, etc). there’s an easier way now.

[ LinuxZoo ] gives you a (virtual) server, running Linux, for FREE. You just need to register with them to get it. What’s more, it even gives you tutorials to help you learn, and quizzes to test your newfound knowledge.

Kudos to the LinuxZoo crew for this service.
