Routing problems
I'm running 3.4 on a machine with 2 fxp interfaces. The kernel is
GENERIC with RAID and DUMMY_NOPS enabled (that's it).
I had fxp0 plugged in and everything was running fine. I then decided to
use fxp1 instead. So I moved hostname.fxp0 to hostname.fxp1 and
rebooted. Same network cable (different NIC), same IP, etc.
After that, I now get "No route to host" for every tcp connection I try
to make (icmp and udp work fine). For example:
# ftp 129.128.5.191
ftp: connect: No route to host
ftp>
However:
# ping 129.128.5.191
PING 129.128.5.191 (129.128.5.191): 56 data bytes
64 bytes from 129.128.5.191: icmp_seq=0 ttl=239 time=34.350 ms
--- 129.128.5.191 ping statistics ---
1 packets transmitted, 1 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 34.350/34.350/34.350/0.000 ms
#
Any ideas? I'm thinking I missed something when I moved NICs, but I'm
pretty sure this doesn't make sense.
I've even tried explicitly adding a route going 129.128.5.191 -> router
and I still get the same behaviour.
