[KLUG Members] restricted bash

[Peter Buxton]

Just checking: am I nuts or should this work?

/bin/rbash is a symlink to /bin/bash. According to the man page, if bash
sees that it is called as rbash, it should run restricted: i.e., it should
run as if it had been called as 'bash -r'.

It does not do this on my Debian box. It does not do this on someone
else's RH 8.0 box. It sets the BASH and SHELL vars right, but is not in
restricted mode. This makes it impossible to set restricted accounts in
/etc/passwd. 'bash -r' does work properly. I suppose if we set a block in
/etc/profile:

if [ $BASH == /bin/rbash ] ; then
  exec bash -r
fi

that would work, but really, it should already -- unless I am missing
something important.
