I just found this nice little tool; -- -- -- scamper is a program that is able to conduct Internet measurement tasks to large numbers of IPv4 and IPv6 addresses, in parallel, to fill a specified packets-per-second rate. Currently, it supports the well-known ping and traceroute techniques, as well as radargun, ally and mercator. (On some other OS it also supports sting, and parts of tbit). -- -- --
this has loads of features, for example detecting load-balanced paths, determining maximum MTU at various hops on a path, etc. see the manuals for more information. it does privsep; there will be an accompanying user.list commit for the unprivileged user account. $ sudo scamper -c 'trace -M' -i 2a01:348:108:108:a00:20ff:feda:88b6 traceroute from 2001:4b10:1002:100:21b:21ff:fe2d:f70c to 2a01:348:108:108:a00:20ff:feda:88b6 1 2001:4b10:1002:100:20d:b9ff:fe04:a330 0.483 ms [mtu: 1500] 2 2001:4b10::2 13.109 ms [*mtu: 1450] 3 2001:4b10:0:8007::1 13.616 ms [*mtu: 1450] 4 2001:7f8:4::999e:1 14.053 ms [*mtu: 1450] 5 2a01:348::27:1:1 15.032 ms [*mtu: 1450] 6 2a01:348:0:4:0:3:1:1 14.773 ms [*mtu: 1450] 7 2a01:348:108:108:a00:20ff:feda:88b6 15.610 ms [*mtu: 1450] the "on some other OS" features need to use the OS's firewall to prevent the OS from seeing responses to certain types of packets, this currently only supports ipfw. OK?
