strange ping problem

hi
i have a strange ping problem under redhat 9
i have a big response time from one of my computers (192.168.1.249) when i'm pinging it from my redhat machine, if i'm pinging the same machine (192.168.1.249) from any other host i get normal responses
and i also can ping normally from that machine (192.168.1.249) to the redhat box
i restarted the redhat box but didn't help
i have no firewall rules for my interior network
thank's guys

what's your big response time?
what os & cpu is running on .249?
is it the same route for all machines?

tell us little more about the used nic's & how your network looks like.

sl mritch.

i had from 50 ms to 400 ms response times
i had 2 gateways configured on that machine and after i removed one of them i had normal response: 0.3-0.8 ms
but i still don't know what the problem was

Greetings
My *guess* would be a malfunctioning NIC on the RH9 system. It's just a theory, my best attempt while not knowing your network.

i don't think the NIC is bad because i can ping normaly the rest of my network
but thank's anyway

if you route through two gw check which way the package went - i think it made a few tries to find it's destination and pingpong'd some wrong routes on either the first ore the second gw. do a traceroute. do you *need* to specify more gw's?

it could be something like this but i still don't understand why it happened, because the two machines are on the same network and it shouldn't use any gateway to ping the redhat box
but windows 98 is full of surprizes
