TraceRoute is a graphical version of the common Windows networking utility "tracert". It's main purpose is to find the bottleneck
in the connection between your machine and a remote host. This can be useful for troubleshooting timeouts when connecting to a remote machine.
Say you have a really slow ping (>500ms) to www.yourdomain.com. Now you want to find out if it's your web server, or if it's one of your ISP's routers.
First you will enter "www.yourdomain.com" for the host field in the TraceRoute toolbar.
You can keep the default packet size, timeout, and count (maximum number of routers to go through).
Now you simple click the "Trace" button, or choose "Trace" from the File menu.
First TraceRoute will lookup the hostname, so it may take a few seconds to start, then you should see a line indicating the ping status of
the first router on your way to www.yourdomain.com. If you see "timeout" in the results, then either you need to increase your timeout value,
check your internet connection, or that router is down. Otherwise you should see the time in milliseconds that it took to send and receive an
ICMP message from the first router. After this, you will see a line for each router that comes next until you finally get a ping from www.yourdomain.com.
Now you can look to see which of the routers has the highest time, and that is your bottleneck. You can also click the check box to look up each hostname
on the way to your web server. This will give you a good idea of which ISP is having the problem.
The timeout value is in milliseconds, so 1000 milliseconds is equal to 1 second.
In general, 1000 milliseconds should be more than enough time to do a ping.
The packet size is good for testing how long it takes to send larger packets, for instance, if you know that you usually send and receive
large packets of 4096 bytes (4k), then you can use that for your size, and increase your timeout value,
then see exactly how long it takes to send/receive a packet of that size.
The count value is for setting the maximum number of hops to go through before reaching the host.
