Does anyone know of an easy way to scan for issues with path mtu discovery along a hop path? E.g. if you think someone is black-holing along a route, or even on the endpoint host, could you use some obscure nmap flag to find out for sure, and also to identify the offending hop/router/host? What tool would you use to test for this, and how would you do such a test?
Patrick, tracepath on Linux and mturoute on windows will tell you what is the path's mtu. If I remember correctly, mturoute gets confused by some of the icmp messages. -- Marcin Antkieiwcz
