Hi,

I have an host running Knoppix 3.8.1 from CD: I started the Knoppix Terminal Server on it.

I have another host: I booted it off the Terminal Server using PXE.

Knoppix booted up fine on the client host, but when I tried to start a root session (su -), sudo didn't work, I got the following error message:
sudo: must be setuid root
That prevents you running any root task with sudo on the client host.

Here is an excerpt from the sudo FAQ:
Sudo must be setuid root to do its work. You need to do something like `chmod 4111 /usr/local/bin/sudo'. Also, the file system sudo resides on must *not* be mounted (or exported) with the nosuid option or sudo will not be able to work. Another possibility is you may have '.' in your $PATH before the directory containing sudo. If you are going to have '.' in your path you should make sure it is at the end.
Indeed, if I issue the 'mount' command, I see that the /cdrom filesystem is mounted on the host client via NFS from the Terminal Server with the nosuid option.

I need to run some root tasks (e.g. mount a local partition) on the client host.

How can I fix the problem or workaround it?

Thanks.
