I have install the New version of RH (6.1) I configure mi wvdial.conf correctly. When I tray to connect an error has report. pppd n01 my modem (US Robotics S. external) call correctly my ISP, the PAP negotiation is correct, i see the message of my ISP! but I wait 2 second and the connection go down! I suppose that is a pppd Bug!
This is not a bug , try changing "lock" to "noauth" in /etc/ppp/options Although if you have a Nic on the same system, and a default gateway configured on that , after dialing the machine won't be able to switch and send the packets through the ppp0 interface. If you ever know how to fix this let me know via email please walsh
