Re: Allow FTP in, but not shell login




Try setting the shell to /bin/true (and make sure this is listed in /etc/shells). /bin/true returns a zero result and exits. It allows you to "log in" via daemons that require a valid shell, yet won't allow telnet-style access (no real shell, just a "true" result).

I change mine to /bin/false.  It runs and gives a nonzero return code.

If you try to su to a user with a shell set to /dev/null, what happens?
/bin/false just exits the su, even from root.
