How can start restricted bash from /etc/passwd

wvsa — Wed, 04 Oct 2006 17:51:57 GMT

Greetings all;

Running redhat linux and would like to have a user run restricted bash (bash -r) when they login. Trying to figure out how I can do this, have seen references to rbash but have not seen rbash for redhat linux.

Thanks in advance for your help!

Shalom Norm,

You can install rbash as a binary and if it works set it as a shell in /etc/shells and then use it in /etc/passwd as the shell

Hello Stephen;

Where can I get rbash, could not find it via up2date, did not find it on the redhat site. Thanks for your input.

IMHO,you don't need to install rbash:

cp /bin/bash /bin/rbash

and then edit /etc/passwd respectively (i.e. setting /bin/rbash as shell for certain account).

In fact, there is no need to copy the bash to rbash, just create a symlink and set that shell in the passwd file:

ln -s /bin/bash /bin/rbash

Gentlemen;

The link of /bin/bash to /bin/rbash worked! That was exactly what I needed.

Thanks so much.
