Hello all. I have a problem which strikes me as most strange, and
this is the best group I can find to look for help.
I've got a box running the 1.2.13 kernel. It has an ethernet
interface to the LAN (3Com 3C509B -- works like a champ one its PnP is
diabled), and a couple of modems making SLIP connections. As of
mid-December, it was doing just what it should: packets routed across
the interfaces quite nicely.
Now it has stopped. Each interface works fine -- I can ping the
outside world through the SLIP links. I can send mail through the
SLIP links. I can do anything through the LAN interface. But it just
will not forward packets between the two. I haven't changed the
kernel. In fact, I rebuilt the kernel from sources which haven't been
touched, and it's still behaving this way.
The only wrinkle on this story happened in late December, when the box
crashed twice from power outages. Each time, it came back just fine.
The disk is OK by fsck. But ever since (though I don't have the
timing well isolated), it will not forward packets.
Anyone know what's going on? Anyone know a way I can log packet
traffic on both interfaces, to be absolutely sure packets aren't
crossing? I'm just at a loss at this point.
Please e-mail replies to me, as well as posting.
Thanks,
