NAME

traceroute6 — print the route IPv6 packets take to network host

SYNOPSIS

DESCRIPTION

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

The options are as follows:

-A

Look up the AS number for each hop address. Uses the DNS service described at http://www.team-cymru.org/Services/ip-to-asn.html.

-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 only 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.

EXIT STATUS

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