Im trying to install some kind of "quota" for my users on my server.

Ive been messing around with quota, but i can't get it working. Im planning to sell web hosting but i need to limit the amount of space a user can have.

my file structure:



I need to initialize quota for /home/user1 and /home/user2.

If it helps, my /etc/fstab is:
proc  /proc       proc    defaults    0    0
none  /dev/pts    devpts  rw          0    0
  • Ubuntu Server 11.04
  • Hosted on a VPS

Thanks for any help you can offer
