easy way to scan for issues with path mtu discovery?

Hi all, 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? Seems to me this happens often enough that someone has already figured it out, so I am trying not to reinvent the wheel. All I can think of would be to handcraft packets (which is laborious at best). Google has not been kind to my researches so far. I appreciate any help! --Patrick Darden _______________________________________________ firewall-wizards mailing list firewall-wizards () listserv icsalabs com https://listserv.icsalabs.com/mailman/listinfo/firewall-wizards
