traceroute problem

rayres · 06-11-2002, 11:36 PM

I am running redhat 7.3 If I use the MY TRACEROUTE program that comes with redhat traceroute seems to work fine. If I use traceroute from the command promt or xtraceroute it does not works at all.. Ping does work to the internet and everywhere else.. All firewall is turned off
I just get this when using traceroute from the command prompt

you may be tracerouting wrong host, or host that has echo blocked

This appears to be a network problem. The *** here means that for these TTLs ( 1,2,3 in this case) there was no ICMP TTL exceeded message received from the intermediate hops.

There can be many possibilities, check ur network setup/conectivity using icmp ping or evem tcp pings(use nmap or xnmap in case icmp filtering is being done somewhere).

This is usually a reverse-DNS issue. If you use the option -s and then add your IP, so that traceroute knows where to have the packets echoed back to, then you should get return times.
