traceroute

This program attempts to trace the route an IP packet would follow to a remote host by launching UDP probe packets with a small ttl (time to live) then listening for an ICMP time exceeded reply from a gateway.

Probes start with a ttl of one and increase by one until we get an ICMP port unreachable (which means we got to host) or hit a max (which defaults to 30 hops and can be changed with the -m flag). Three probes (change with -q flag) are sent at each ttl setting and a line is printed showing the ttl, address of the gateway and round trip time of each probe. If the probe answers come from different gateways, the address of each responding system is printed. If there is no response within a five second timeout interval (changed with the -w flag), an asterisk (*) is printed for that probe.

For IPv4 (-4 flag) or IPv6 (-6 flag) tracerouting can be forced using the appropriate flag. By default, the program tries to resolve the name given and automatically choose the appropriate protocol. If resolving a host name returns both IPv4 and IPv6 addresses, traceroute uses IPv4.

Usage

traceroute [-dFInrvx] [-f first_ttl] [-g gateway][-i iface] [-m max_ttl] [-p port] [-q queries]

[-ssrc_addr] [-ttos] [-wwaittime] [-zpausemsecs] host Table 2-5 traceroute Options

Option	Description
-4	Force IPv4 tracerouting.
-6	Force IPv6 tracerouting.
-f	Set the initial time-to-live used in the first outgoing probe packet.
-F	Set the don’t fragment bit.
-d	Enable socket level debugging.
-g	Specify a loose source route gateway (8 maximum).
-i	Specify a network interface to obtain the source IP address for outgoing
	probe packets. This is normally only useful on a multi-homed host. (See the
	-s flag for another way to do this).
-I	Use ICMP ECHO instead of UDP datagrams.
-m	Set the max time-to-live (max number of hops) used in outgoing probe
	packets. The default is 30 hops (the same default used for TCP
	connections).
-n	Print hop addresses numerically rather than symbolically and numerically
	(saves a nameserver address-to-name lookup for each gateway found on
	the path).
