LinuxLoader have tried to make the ultimate server guide to Kubuntu. 25 pages of everything – enjoy!
Read the massive guide here
lthough we support Kubuntu, the process is same for all these great Distros. In fact, back in the day, Debian was created for building Servers FIRST. It's a stable secure platform that can do a great job. Weather its serving web content, mail, or just local files, these great distros are up to the task!! So complete the basic build first then choose the type of server you want to build.
