Question restrict access of a user to two directories only
Hi all,

I am using RHEL 5.0

I need a user say test to have full access to two directories, say /tmp1 & /tmp2 only other than his home directory.

I do not want to change his login shell which is ksh or bash by default.
Moreover, he should not even have read access of other directories.

Pls help!!

Thanks in adv,
VIKAS

For the user test to be able to run some utilities he may need read access to some files perhaps in /etc or /lib.

Your best bet is to chroot this user - put the user in chroot jail, creates links in his home directory to /tmp1 & /tmp2. This is what is often done with ftp accounts to lock them into completely known file trees
