tracepath Command on Linux: Trace Network Paths
The tracepath command on Linux traces a path between the host and a network address and tries to discover what the MTU (Maximum Transmission Unit) is. Tracepath is a good substitute for traceroute.
It also has a similar command for IPv6: tracepath6.
Example:
$ tracepath www.kernel.org 1: ns1.certificacaolinux.com.br (72.26.225.74) 0.306ms pmtu 1500 1: 72-26-224-1.meganetserve.net (72.26.224.1) 134.005ms 2: no reply 3: no reply 4: no reply 5: isc.sjc06.atlas.cogentco.com (154.54.13.218) 5.693ms 6: int-0-2-0.r1.pao1.isc.org (149.20.65.18) asymm 4 5.010ms 7: pub2.kernel.org (204.152.191.37) asymm 5 3.635ms reached Resume: pmtu 1500 hops 7 back 5It tries to find the average response time of each step in the path and returns the final MTU, the number of hosts for packets to go from the host to the destination and tries to predict the number of hosts from the destination to the host if the route is asymmetric (there is more than one path).

After years of watching professionals waste hours on simple tasks because they didn't know the right Linux tools, I decided to teach.
Today I'm the author of most of LPI's official Learning Materials and mentor to over 14,000 certified students.
That was just one piece. The course teaches the whole path — from your first command to exam day.
