We have a set of 8 servers, all running tru64 v5.1a, pk2. They are all
connected to multiple nets, but all share a common net as well:
Server1 server2 server3 server4 server5 server6 server7 server8
| | | | | | | |
----------------------------------------------------------------
server1/server2/server3 can all reach server8 and vice-versa.
server4/server5/server6/server7 can *NOT* reach server8, nor can server8
reach them.
server4/server5/server6/server7 can reach server1/server2/server3 and
vice-versa.
server1->server7 all know to go out the shared network to reach server8.
server8 knows to go out the shared network to reach server1->server3,
but tries to go out a different default route to reach server4->server7,
even when responding to pings/ssh/tcpdump packets coming in the shared
common network from the problematic servers.
server8 also knows the correct MAC address of *all* the servers on the
shared common network, and the correct IPs associated with those MAC
addresses.
There is nothing odd in /etc/routes or "netstat -r" output on *any* of
the servers, either the ones that *can* communicate or those who
*cannot*.
I'm baffled. If this wasn't a prod env. I'd reboot the d*mn server8, but
that's not an option. Anyone have any suggestions/insights???
