username and password in that dial box, then it's not working perfectly. I
am getting error like "Your Server dose not Respond to Network
request.Please contect your administrator" -- Error 650.
My aim is enebling AUTOPPP. I am using mgetty. in login.config, inittab
and mgetty.config I have given all below settings.
