i managed to get KNOPPIX installed on a compaq presario. It has a wirless pcmcia card. I have tried to launch kwifiManager from the knoppix menu and I get prompted for the root password with this dialog:
Code:
The action you requested needs root privileges.  Please enter root's password below or click Ignore to continue with your current privileges

Command:  kdesu '--' 'sudo' 'kwifimanager'
When I enter the root password it says 'The program 'SU' is not foud; make sure your PATH is set correctly.

When I try to open a terminal window to check/set the path, i get the error:

Code:
Konsole is unable to open a PTY (pseudo teletype).  It is likely that this is due to an incorrect configuration of the PTY devices.  Konsoles needs to have read/write access to the PTY devices.
Is there some sort of configuration I neglected to set up?
