Backgorund - I'm a linux noob and yellow dog is my first working distro.

I have everything set up but would like to netowork my PC. When I set up the PC I set the security level to 'high' and now I can't set it to any other level even when I am looged in as root. Therefore I can't network or browse the internet via a gateway machine.

I believe the security manager on yellow dog linux is the same as red hat.

I am guessing I am going to have to change this at the command line but I have no idea how.

Any help would be appreciated

What do you mean you cant set it to any other level, are you getting an error?

just use <tab> and <spacebar>

and ok and exit.
