September 17, 2005 TRACEROUTE6 8

### NAME

traceroute6 - print the route IPv6 packets will take to the destination

### SYNOPSIS

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

### DESCRIPTION

-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 network, 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
