.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility
|
|
uses the IPv6 protocol hop limit field to elicit an ICMPv6 TIME_EXCEEDED
|
|
response from each gateway along the path to some host.
|
|
.Pp
|
|
The only mandatory parameter is the destination host name or IPv6 address.
|
|
The default probe datagram carries 12 bytes of payload,
|
|
in addition to the IPv6 header.
|
|
The size of the payload can be specified by giving a length
|
|
(in bytes)
|
|
after the destination host name.
|
|
.Pp
|
|
Other options are:
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
Debug mode.
|
|
.It Fl f Ar firsthop
|
|
Specify how many hops to skip in trace.
|
|
.It Fl g Ar gateway
|
|
Specify intermediate gateway
|
|
.Nm (
|
|
uses routing header).
|
|
.It Fl I
|
|
Use ICMP6 ECHO instead of UDP datagrams.
|
|
.It Fl l
|
|
Print both host hostnames and numeric addresses.
|
|
Normally
|
|
.Nm
|
|
prints only hostnames if
|
|
.Fl n
|
|
is not specified, and only numeric addresses if
|
|
.Fl n
|
|
is specified.
|
|
.It Fl m Ar hoplimit
|
|
Specify maximum hoplimit, up to 255.
|
|
The default is 30 hops.
|
|
.It Fl n
|
|
Do not resolve numeric address to hostname.
|
|
.It Fl N
|
|
Use a packet with no upper layer header for the probes,
|
|
instead of UDP datagrams.
|
|
.It Fl p Ar port
|
|
Set UDP port number to
|
|
.Ar port .
|
|
.It Fl q Ar probes
|
|
Set the number of probe per hop count to
|
|
.Ar probes .
|
|
.It Fl r
|
|
Bypass the normal routing tables and send directly to a host
|
|
on an attached network.
|
|
If the host is not on a directly-connected network,
|
|
an error is returned.
|
|
This option corresponds to the
|
|
.Dv 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).
|
|
.It Fl s Ar src
|
|
.Ar Src
|
|
specifies the source IPv6 address to be used.
|
|
.It Fl U
|
|
Use UDP datagrams for the probes.
|
|
This is the default.
|
|
.It Fl v
|
|
Be verbose.
|
|
.It Fl w Ar waittime
|
|
Specify the delay time between probes.
|
|
.El
|
|
.Pp
|
|
This program prints the route to the given destination and the round-trip
|
|
time to each gateway, in the same manner as traceroute.
|
|
.Pp
|
|
Here is a list of possible annotations after the round-trip time for each gateway:
|
|
.Bl -hang -offset indent
|
|
.It !N
|
|
Destination Unreachable - No Route to Host.
|
|
.It !P
|
|
Destination Unreachable - Administratively Prohibited.
|
|
.It !S
|
|
Destination Unreachable - Not a Neighbour.
|
|
.It !A
|
|
Destination Unreachable - Address Unreachable.
|
|
.It !\&
|
|
This is printed if the hop limit is <= 1 on a port unreachable message.
|
|
This means that the packet got to the destination,
|
|
but that the reply had a hop limit that was just large enough to
|
|
allow it to get back to the source of the traceroute6.
|
|
This was more interesting in the IPv4 case,
|
|
where some IP stack bugs could be identified by this behaviour.
