I just installed Knoppix 3.3 (from CDs purchased from TuxCDs.com), and I'm having the worst luck getting it to connect.

I'm able to connect to my ISP with no problems if I boot from the CD. But when I install to the hard drive, I can't connect as the Knoppix user. Or rather, I connect, but nothing happens. The graph displayed by the "details" button is flat, and the in/out byte count doesn't change beyond a few handshake bytes.

I've tried creating a new user (with adduser), in case I messed up the "Knoppix" user, but the new user can't even bring up KPPP for some reason. I click on the program, but nothing happens -- program appears to terminate quietly.

Meanwhile, root seems to work fine, either logged in or using the "Modem Dialer" option under "Network/Internet" from the pengin-in-a-circle toolbar icon.

Is there some sort of file permission problem, perhaps? If that's the problem, a chmod should take care of it (right?).

And it would be nice (though not essential) to get the new login working on the new login, just so I can have a clue. This is my first experience with Linux, and while I can see the power, I've still got to convince the rest of the local user community (that is, my wife and kids).

Thanks!
