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

NAME
     traceroute6 - print the route IPv6 packets take to network host

SYNOPSIS
     traceroute6 [-dIlnrv] [-f firsthop] [-g gateway] [-m hoplimit] [-p port]
                 [-q probes] [-s src] [-w waittime] host [datalen]

DESCRIPTION
     The traceroute6 utility details the route IPv6 packets take to reach a
     network host.

     The options are as follows:

     -d      Debug mode.

     -f firsthop
             Specify how many hops to skip.

     -g gateway
             Specify an intermediate gateway (traceroute6 uses a 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 on-
             ly numeric addresses if -n is specified.

     -m hoplimit
             Specify a maximum hoplimit.

     -n      Do not resolve numeric addresses.

     -p port
             Set UDP port number to port.

     -q probes
             Set the number of probes 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
             network, an error is returned.  This option corresponds to the
             SO_DONTROUTE socket option; it can be used to ping a local host
             through an interface that has no route through it (e.g. after the
             interface was dropped by a routing daemon).

     -s src  Specify the source IPv6 address to be used.

     -v      Be verbose.

     -w waittime
             Specify the time delay between probes.

     The traceroute6 utility exits 0 on success, and >0 if an error occurs.

HISTORY
     The traceroute6 command first appeared in the WIDE Hydrangea IPv6 proto-
     col stack kit.
