TRACEROUTE6(8)						    BSD System Manager's Manual 					    TRACEROUTE6(8)

NAME
traceroute6 -- print the route IPv6 packets will take to the destination SYNOPSIS
traceroute6 [-adIlnrv] [-A as_server] [-f firsthop] [-g gateway] [-m hoplimit] [-p port] [-q probes] [-s src] [-w waittime] target [datalen] DESCRIPTION
-A Turn on AS# lookups and use the given server instead of the default. -a Turn on AS# lookups for each hop encountered. -d Debug mode. -f firsthop Specify how many hops to skip in trace. -g gateway Specify intermediate gateway (traceroute6 uses routing header). -I Use ICMP6 ECHO instead of UDP datagrams. -l Print both host hostnames and numeric addresses. Normally traceroute6 prints only hostnames if -n is not specified, and only numeric addresses if -n is specified. -m hoplimit Specify maximum hoplimit. -n Do not resolve numeric address to hostname. -p port Set UDP port number to port. -q probes Set the number of probe per hop count to probes. -r Bypass the normal routing tables and send directly to a host on an attached network. If the host is not on a directly-attached net- work, an error is returned. This option can be used to send probes to a local host through an interface that has no route through it (e.g., after the interface was dropped by route6d(8)). -s src Src specifies the source IPv6 address to be used. -v Be verbose. -w waittime Specify the delay time between probes. EXIT STATUS
The traceroute6 command exits 0 on success, and >0 on errors. SEE ALSO
ping(8), ping6(8), traceroute(8) HISTORY
The traceroute6 command first appeared in WIDE hydrangea IPv6 protocol stack kit. BSD
September 17, 2005 BSD
