Strange routing issue on HPUXi v2

[William E Howard]

I tried posting this earlier, but I think whatever it was ate it, since it is no longer there.

Running an rx2620 in my lab environment. Trying to get it up on the network. For some reason, it is unable to see the gateway or anything beyond it, but the local segment comes back fine.

Able to ping and telnet within subnet, but unable to ping gateway nor can anything beyond gateway ping it. Other machines (windows only) have no problem.

Have run set_parms numerous times, verified netconf and netstat, both look ok.

System Info Below:

don't put information in ROUTE_MASK field.

ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="192.168.97.1"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

Still if you do have problem then move /etc/rc.config.d/netconf file and then use set_parms to recreate it.

IT_2007, I had tried that. I added the ROUTE_MASK since it didn't work without it and it was just a test.

I did finally manage to track it down. Issue was with my switch, set to ignore IP's above a certain number for security purposes. Network guy never told me about that little 'feature' he had setup.
