Traceroute Timing out


I have instaled the newest trace route package and everytime I use it the second hop and anything after times out and comes up as *. My ping works just fine. I just cannot seem to get traceroute to work.

It could be your (or your ISP's) router/firewall limiting packets. ping uses ICMP by default, traceroute on my system uses UDP by default.

On my box, it doesn't use a single port, each connection goes out to a different port.

If it's your firewall doing the blocking, you can configure iptables to allow outbound UDP traffic and incoming UDP traffic for established connections. To check if it's your router, have you tried a traceroute to it and then a traceroute to something just outside (like your ISP's mail server)?

I have traced to my router and it works but anything outside of my router does not work, including my isp's mail server.

When Tried to traceroute to my dns I got this.

jmw5208@jmw5208-linux:~$ traceroute cns.summitpark.pa.pitt.comcast.net
traceroute to cns.summitpark.pa.pitt.comcast.net (68.87.75.194), 30 hops max, 52 byte packets
1 192.168.0.1 (192.168.0.1) 0.212 ms 0.214 ms 0.280 ms
2 * * *
3 * * *
4 * * *
5 * * *
6 * * *
7 * * *
8 * * *
9 * * *
10 * * *

I used the escape key to stop it at ten or it would have just kept going and my dns is no more than 6 hops from where I am.
