Subject:   problems with the ep (ethernet) driver? 2.2.[67]
Message-ID:  <m10FOro-00080sC@mailbox.reptiles.org>

next in thread | raw e-mail | index | archive | help

we have a core router running 2.2.7.
it has 2 PCI de ethernets, a PCI vx ethernet and an ISA ep ethernet.

we have interior router running 2.2.6 with PCI de ethernets.

the interior machine is connected to the ep ethernet of the core machine.

recently, we swapped out the previous core router (was NetBSD with ed ethernet)
for the above machine.

since the swap, gated (running on both machines) seems to lose contact
and the interior machine (and/or the core) decides that it can't pass
packets over the route.

oddly enough, if i fire up a tcpdump on the core router ep interface,
packets start flowing instantly.

my feeling is that for some reason, kicking the ep driver into promiscuous
mode causes gated to retrun to normal operation.

is there some bug with the ep driver, and promiscuous mode?
or is it possibly a bug in gated, misinterpreting the ep driver?
