TweakCoH question
Submitted by Flux Wraith on Sun, 10/03/2004 - 11:09am.
When running a tracert off of TweakCoH, it always gets to the 10th hop just fine (so-7-0-0.edge1.washington1.level3.net), but then it always times out. I'm certain the servers are up, as I just logged on, so why does it always time out here?

I wanted to add that this is only an issue with the tracert program that MS includes with windows.
I believe that Unix traceroute does not use Echo to do either ping or trace, so that it should succeed. I will likely be coding my own in the future just haven't had time just yet.

Well...its simple.Echo is
Well...its simple.
Echo is Message number four (4 or is it 8?) in the ICMP protocol.
Its something that typically people turn off response for on a server when its behind a firewall so it can remain anonymous on the internet and not be ferreted out. This will kill all Ping and Tracert (which is just, basically though not quite, a layer on Ping) requests.
When I first wrote TweakCoH during beta, they had not yet turned off Echo on the servers, so I had the feature added in.
Now that its turned off, you can only tracert as far as you can manage to ping an IP along the way.
And the fact that you go through level3 at all is great -- Level 3 has one of the best infrastructures in the entire nation, and also one of the most up to date and recent.
