I only changed my settings to that of what is on my Slackware default setup. e.g

chmod u+s /usr/sbin/pppd
chmod u+s /usr/bin/kppp

I can dial up fine and connect. But nothing happens. Even though I am connected, when I try to access any site I get an error message saying site not found.

I added myself to the dialout group, but it doesn't make any difference.

Any ideas?
