While I haven't done much debugging in this area, (haven't had a lot of time recently), I have two systems that started having the same problem once I upgraded from 2.2.7-stable to 2.2.8-stable. (I know these aren't -current, but the merge of the ppp code was brought over for 2.2.8) The first system I upgraded is using an Adtran ISDN "modem" connected through a serial port. The system was working perfectly for about 15 months (since installation) until I upgraded the box to 2.2.8-stable. Now, when the line is dropped, ppp doesn't "see" the carrier lost and just sits there. For a quick fix, I just wrote a script that resets ppp if it can't ping a known server on our end. At first I thought it could be hardware failure until I updated another 2.2.7-stable box to 2.2.8-stable. (This one is using a USR Courier V.90 modem and has been working fine for about a year.) When the same thing happened (modem dropped carrier, ppp didn't pick it up) I started to think it wasn't a hardware failure. It's unlikely that both of these systems started failing at the same time, especially when the problem happened immediately after upgrading to 2.2.8-stable. Regardless, I'd be happy to run specific debug logs and send them to you if you want. Jaime Bozza Nucleus Communications, Inc.
