Introduction

Traceroute is the program that shows you the route over the network between two systems, listing all the intermediate routers a connection must pass through to get to its destination. It can help you determine why your connections to a given server might be poor, and can often help you figure out where exactly the problem is. It also shows you how systems are connected to each other, letting you see how your ISP connects to the Internet as well as how the target system is connected. Traceroute is not installed by default in MEPIS 8, but is available from the repos.

Usage

To run traceroute, open a terminal and type:

traceroute server.name

Here is some sample output from the first link below:

By default, traceroute makes 30 "hops" (jumps from server to server down the line). Follow the first link below on how to read and use the output.

There is also a package that combines traceroute and ping available from the repos called mtr that presents the output in a very readable GUI.
