Re: Unable to su as a user, I get: Cannot execute /bin/bash: Permission denied

that...i get an xterm window pop up and it states the same thing :
Cannot

Er... have you by any chance tried checking out the permissions for
that file? It'll be executed by the user, not root. Try 766.


That should probably be 755 , not 766, you really dont want /bin/bash
writeable by anyone but root.

su root /bin/sh
then chmod a+x /bin/bash

i think someone has been messing with you.

Also to be a right prat, chmod a-x `which chmod` (don't do it, but i've
always been tempted to try it.....)

Worth noting that in runlevel 1 you get a root sh , so you could put it
right that way as well.
