Traceroute Problem
I have an HP machine (hp 11.11) and a linux machine, both are in the same network with no firewall in between.
When i do traceroute Linux from the HP box it keeps timing out but the other way around (linux to hp) works fine.
I tried traceroute form HP box to another machine in same network (and subnet) and it works fine, its just this linux box that it keeps timing out..
Please advice...

Re: Traceroute Problem
traceroute -d linux also gives the same output:
traceroute -d persephone
traceroute to persephone.sbsint.com (12.20.194.27), 30 hops max, 40 byte packets

Re: Traceroute Problem
Can you try another nic?? Also did you check if iptables in in play or not?? If yes, disable it for tests and do it. Also is there a firewall in between??

Re: Traceroute Problem
there is only one nic on the hp machines, i have tried the -d,w, v etc options with trace route but there is no difference in the output.
The strange part is that the hp machine and linux box can talk to each other.
When i do a ping on either of the 2 machines i get a response.
I dont understand this coz, both ping and traceroute sends ICMP packets, so why is one working and the other not??

Re: Traceroute Problem
Thankyou for your reply.
I tried using traceroute -i lan0
The funny part is that if traceroute was broken of somehting it should not work for other machines either, but it does, when i do a traceroute to any other machine it goes throught perfectly..
is this something to do with linux machines?
