OK, I set up a fileserver/printserver in my school LAN for my students to save/print their work. They typically login via ssh or an X client.

My problem is that when I intalled KNOPPIX as DEBIAN (20031119) on the hdd I added users with adduser. However, every one can see everyone else's home dirs and read the contents of their files. Is there a way to prevent this when I create a user? I mean all files created by my students are rw-r--r-- (ie: chmod 644) and their executables are rwxr-xr-x (ie: chmod 755). Can I make everyone their own group so they can read only their own files or have the files saved rw------- or rwx------?

TIA,
AJG
