Help! Can't su knoppix in chrooted files system.

[rickenbacherus]

It says-

Can't sudo, must be setuid root.

But I am root and I'm using su knoppix. I thought I could set a root passwd as you normally would and so I used passwd root. Then this trouble started and I can't become knoppix anymore. What should I do to fix it?

Not sure what you mean by "can't become Knoppix anymore" Have you done a hard drive install? If so log in as root, open a term and do this:

adduser <someusername>

And just enter BillyJimJoeBob or whatever username you want. Follow along and you'll have a username you want instead of Knoppix. Then as root you'll need to add your new username to /etc/sudoers and the new user will be able to do thigs as root. Here is my /etc/sudoers file:

# sudoers file.
#
# This file MUST be edited with the "visudo" command as root.
#
# See the man page for details on how to write a sudoers file.
#

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root	ALL=(ALL) ALL

glenn	ALL=NOPASSWD: ALL

This way I can just use sudo and not have to enter a password each time.

If you want to change root password then log in as root and run passwd. It simplifies things.

HTH (If I've totally misunderstood you post back).
