i'd like to add a user that will conect to my host by FTP and execute some commands, but I want to limit his activity to a specific folder (he can't even leave that folder) and also limit his commands (he can't create files, delete anything, etc...). Thnx people.
OK, but what if I wasn't using ftp ? How to reduce the commands a normal user can execute ? But thnx for the answer above, guess it solves the issue for this special case...
I found a JAIL script in PERL that does all the boring stuff like copying bash into the folder so that it works, and copying dependencies. It's doing what i wanted, but there's still one doubt...If I use CHROOT, how can I do so that when the user logs in the chroot runs and makes his / the folder I want...
Yes this perl script should do the job but I prefer to do it myself. Makejail?
To check if he is really chrooted, make a ps, take the pid of his bash. then go in /proc/<pid>
and look at the file root. this file should point to the root of the chroot.
Should display
root->/jail/
