hello,

this is an example output of tracepath with a specified pktlen:

Quote:

# tracepath -l 28 10.100.100.4
Error: length must be >= 28
# tracepath -l 29 10.100.100.4
1: 10.0.0.1 0.464ms
2: 10.100.100.1 9.557ms
3: somehost.com 15.503ms reached
Resume: pmtu 29 hops 3 back 62


I did not know that 28 is not >= 28 :)

Sorry mate, but 28 *is* greater than OR EQUAL to 28

Cheers

This is net-misc/iputils-20100418-r1 - tracepath claims that ! 28 >= 28.
