Tracert Question

Can't really remember, it's been awhile, but I seem to remember using the tracert command to pinpoint problems in my connection to game servers. Correct me if I'm wrong.

Aside from Linden issues with connection problems, server issues, sim issues, the list goes on--problems on their end, in other words--I'm wondering about using the Windows tracert command to see if I'm slowing down somewhere in between me and the server I'm trying to connect to.

From playing previous online games, I used tracert (I think it was tracert) to pinpoint connection issues on my way to the game server in question--and had success with my ISP in re-routing my connection around problem in-between servers.

I would like to make sure I'm getting the best path, least packet loss, possible to the Linden servers.

Is tracert the thing that would show me this, or is there another command or program available, or are there SecondLife specific tools to help me see what's happening on the way to Linden's servers?

If tracert is the thing, how do I get the Linden/Sim server info to plug into the tracert command to follow my path?

I also seem to remember a gui Windows program that did something like this, showing you each server you went through to get where you were going in order to find the bottlenecks. Anyone know of this, or something similar? Something that will run on Windows 2000.

Tracert is the program that will tell you the path your packets are taking FROM you TO linden labs (note, theoretically it may not be the same route back, but in 99% of cases it will be)

It will also indicate at what stage along that route packet loss appears to be occurring, but, this can be a very misleading figure, since traceroute uses ICMP packets which are handled differently by routes than TCP or UDP packets (which the game uses), so just because a router is dropping ICMP does not necessarily mean that it will drop your actual game packets.

There is indeed a widows-friendly traceroute - I believe that WinMTR ( http://winmtr.sourceforge.net/ ) is the one recommended in the SL wiki, it is definitely a good app.

If you do find what looks like a problem using traceroute, post up the results you're getting here, as there are several people on the forum who have skills and experience in reading and interpreting such logs :)

Oh, the server at the game end to point it at is data.agni.lindenlab.com which is on the same network as the live grid sim servers.
