Add guest user

I would like to add a guest user , however, I would like the guest be able to read his home directory only ! What shall I do ?

I am running RedHat9.0 GNOME !

i don't think this can be done, for you must be able to read /usr/bin, /usr/lib etc to be able to run anything for that user (a desktop manager for starters!). the only way is to create, perhaps an entire system in a hidden folder (eg. /home/user/.sys/)..... no that won't work either!

Well, one could put the user in a chroot-jail

Cheers,

Check out the various options for restricted shells. Both bash and (I think) ksh have a way that they can work in restricted mode (don't allow a user to cd or run any command outside his $PATH). If you grep for rbash you'll find some good info, I think. I'm not sure if this will prevent the user from ls'ing other dirs though, so it may not be as secure as a chroot jail, but easier to set up.

so you can "chroot /home/user" and have a working system still???? no, that's just too tricky surely.
