Unable to PING server

[ManagerJay]

We have two Linux servers on our network. We can ping Server1 from Server2, but we cannot ping Server2 from Server1. Both have internal ip addresses in the 10.129.X.X range with a subnet mask of 255.255.255.0.

I remember reading somewhere, that a vendor had a problem with their ping program, but I cannot remember where I read it, or who the vendor was.

Server1 is a RedHat 6.2 server. I am not sure of the version on Server2 since it is supplied by an outside vendor and I do not have access to the OS.

Additionally, when pinging other network devices from Server1 I will have a response time of 4356.7 ms or higher. Then the times will slowly drop until they return to the 1.9 ms range. Pinging the same network devices from other workstations, etc. will result in a 1.9 ms range repsonse time.

Any help would be greatly appreciated.

Thanks,



Jay

Has Server2 been defined in /etc/hosts or /etc/resolv.conf on your DNS server?

Yes, the server and its alias is defined in /etc/hosts.

You've got a netmask specified that says the first three octets of the IP addresses are the network. Is the first "X" in each servers IP address the same?

On the ping question, it is RedHat that has the problem. I read somewhere that you can regress to an earlier version of ping without any problems, but I can't remember the specifics

I got ahold of the vendor last night and they were able to telnet in and take a look at the server. They found they had made a mistake setting up the network card.

Everything is working fine now (that I have had time to test).

Thanks for your help.
