Need Help Diagnosing PPP Connection Failure



All,

I'm running into difficulty testing an AT&T Wireless EDGE PC card (Sony Ericsson GC82) modem on Debian GNU/Linux 3.0 (Woody). I'm running PPP 2.4.2+20040202-0.backports.org.1. I'm using the "debug" and "nodetach" options in my configuration file. I've got an Ethernet connection established on eth0, and am attempting to establish a PPP connection using the modem. I remove the default route with "ip route delete" prior to starting PPP. When I run "pon," the output is as follows:

OK
AT+cfun=1
OK
AT+cgreg=1
OK

+CGREG: 1

I'm concerned about the following messages in particular:

rcvd [LCP EchoRep id=0x0 magic=0x4f835e98]

rcvd [PAP AuthAck id=0x1 "PAP access OK"]


I'm able to verify the establishment of a new default route using "route -n". I can ping www.yahoo.com. However, ultimately, the script aborts with an error. What to do? I'd appreciate any suggestions offered.

Thanks.

Michael
