| 1. | How can I change my default shell ?
|
|
Use the command chsh or edit /etc/passwd
|
| With root user rights, enter the command yast
then System Administarion->User administration select the user you
want modified with F3 function key and when you come
to login shell again press F3 and select the shell and
finish. When you login as that user you can have the shell you have
assigned in YaST |
| The interactive way to deal with it is through usermod. Something
like (don't quote , read the man page):
# usermod -s USER /qualified/path/to/shell
|
| 2. | How can set the user to a restricted shell ?
|
|
Simply give the user /usr/bin/rbash instead of
/usr/bin/bash as a login shell. If bash is either
called with the -r parameter or as
rbash, it will react as restricted shell. See
info bash for further documentation.

This is what I came up with after playing with things for a few
minutes.
