This wiki is a community-maintained resource about everything there is to know about IPFire.
MTR or "My Traceroute" combines the functions of Traceroute and Ping in one tool.
MTR can be installed as an IPFire addon over the console with:
pakfire install mtr
or over the IPFire web interface via Pakfire
MTR works over the ICMP execution (ping) with a Time-To-Live Value (TTL) starting with 1 to the first hop (router).
Hereby the expired time of the packet are recognized and the packet will be discarded and a ICMP-response "Time-to-live exceeded" will be send back to the sender.
The next request becomes a TTL of 2 and so on. The information of each hop (routers) will be collected by the increased TTL-values and shows the way of the data packages to the target host.
MTR starts then again to display over a time progression the average of "Best-case" and "Worst-case" values.
For a simplified output use the following command over the console of IPFire or use an ssh-connection for a remote shell:
mtr www.ipfire.org
this should give an similar output like this back:
