F-50 wont talk to network 1

[marvin51796]

I have a RS/6000 F-50 with a PCI nic installed on it running aix 4.3.3. I can ping myself via IP or hostname, but i cant ping anything on the network. I show the system as being active on the port.
Any help would be creatly appreciated.
thanks

You might need to set your default gateway. To check:

netstat -rn | grep default

If you get no output, or the default gateway address is the F-50's address, then:

/usr/sbin/route add default <gateway IP address>

I checked that it is setup for the correct default gateway and has the correct subnet mask for the network.

Does your network equipment have ICMP Echo/Reply forwarding disabled?

Can you ping the F-50 from elsewhere on the network?

I am not sure about the ICMP or how to check that...I am a HP-UX guy sorry....no I cant ping the F-50 from elsewhere.
Thanks for the help

ICMP Echo/Reply are the packets that make up a ping.

Try a traceroute to the host you want to ping:

/usr/bin/traceroute <host>

might yield some clues.

Make sure the NIC on the RS/6000 is set for a specific media speed, not auto_negotiate.

traceroute just came back with alot of 1****, 2**** and that was it...no errors or anything....the card is set to 100 full, and the lights on the nic are on.

(in no particular order)

If you can, move a device (desktop computer, maybe) that you know can talk to the network to the port that the F-50 is on, and see if it still works.

Are the lights on the NIC and the switch/router showing activity?

Have you tried flushing the route table? You'll have to add the default gateway back in afterwards.
