If you still cannot connect, you can try these:
1) open etc/ppp/peers/kppp-options and remove the # in front
of noauth if it is there.
2) open etc/ppp/pap-secrets and make sure your isp username
and password are there, again with no # in front of the line.
3) open etc/ppp/peers/provider and first make sure the correct
modem is listed, mine is on com port 2 so my line reads
/dev/ttyS1. Then this is the biggie because this line was very
wrong on mine. The chat script line should read :
connect “/usr/sbin/chat -v -f /etc/ppp/peers/provider”
That should do it.
By the way when putting settings in kppp (click configure button)
i used PAP and CR/LF and CRTSCTS and 115200 and /dev/ttyS1(which in
my case is com port 2).
Also do not use lock and if you really have to, change everything logged in as root.
