It utilizes the IP protocol's time to live (TTL) +field and attempts to elicit an ICMP TIME_EXCEEDED response from each +gateway along the path to the host. + +Main features: +- Full support for both IPv4 and IPv6 protocols +- Several tracerouting methods, including: + * UDP datagrams (including udplite and udp to particlular port) + * ICMP ECHO packets (including dgram icmp sockets) + * TCP SYNs (in general, any TCP request with various flags and options) + * DCCP Request packets + * Generic IP datagrams +- UDP methods do not require root privileges +- Ability to send several probe packets at a time +- Ability to compute a proper time to wait for each probe +- perform AS path lookups for returned addresses +- show ICMP extensions, including MPLS +- perform path MTU discovery automatically +- show guessed number of hops in backward direction +- command line compatible with the original traceroute +- and much more, see traceroute(8) + +This code was written from the scratch, using some ideas of +Olaf Kirch's traceroute, the original implementation of Van Jacobson +(which was long used before) and some current BSD's ones. + +This traceroute requires Linux kernel 2.6 and higher. + +You can try to contact the author at <Dmitry at Butskoy dot name> . + + +Good tracerouting! + +Dmitry Butskoy + |
