Tracepath : traces path to a network host discovering MTU along this path

TCP/IP command. Trace path to host and report the Maximum Transmission Unit (MTU.) A simplified version of traceroute without options meant for use by unprivileged users. If specified, it will use port to send UDP probe packets. host is the destination hostname or the IP number of the host to reach.

It  traces path to destination discovering MTU along this path.  It uses UDP port or some ran-dom port.  It is similar to traceroute, only does not not require superuser privileges.  It has one option -n which does not resolve ip addresses into their DNS counterparts.

command : Tracepath

Example :

$tracepath smartproteam.com

1?: [LOCALHOST]                              pmtu 1500
1:  dest111111                   0.411ms
2:  dest2222       asymm 1   0.390ms pmtu 1480
2:  dest33333               463.514ms reached

Resume: pmtu 1480 hops 2 back 2

first column shows TTL of the probe, followed by colon.

second column shows the network hop.

rest  of  line shows miscellaneous information about path to the corresponding network hop.

last line summarizes information about all the path to the destination
