[opensuse] su no longer working

I've been doing some rearrangement on my system (SUSE 11.1) using the command su in order to run root required commands. All of a sudden the su command no longer works. The following is an example of what has happened: eck@linux-dria:~>su Password: linux-dria:/home/eck # df linux-dria:/home/eck # cd / linux-dria:/ #ls -lag linux-dria:/ # Notice that nothing happens. What might of happened to cause this? I can login to one of the virtual terminals as root and there is no problem. Thank for any ideas, Terry -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
