How to's?
 

Hey just wondering does anyone know anywhere i can get some how to's on these subjects?

Setup permission for users so i don't have to log into root to do stuff

Setup a network across computer, from linux to windows

Setup a VPN

For the first, you're looking at Sudo or the "sticky bit" and $PATH variable.

The second relates to Samba, the linux <--> windows sharing tool.

Both in the LQ's 'Answers' section (now called Tutorials) and by frequent use of the 'Search' button you should be well-rewarded.

#3 would be openswan.
