75uses the IPv6 protocol hop limit field to elicit an ICMPv6 TIME_EXCEEDED 76response from each gateway along the path to some host. 77.Pp 78The only mandatory parameter is the destination host name or IPv6 address. 79The default probe datagram carries 12 bytes of payload, 80in addition to the IPv6 header. |
81The size of the payload can be specified by giving a length 82(in bytes) 83after the destination host name. |
84.Pp 85Other options are: 86.Bl -tag -width Ds 87.It Fl d 88Debug mode. 89.It Fl f Ar firsthop 90Specify how many hops to skip in trace. 91.It Fl g Ar gateway --- 27 unchanged lines hidden (view full) --- 119.Ar Src 120specifies the source IPv6 address to be used. 121.It Fl v 122Be verbose. 123.It Fl w Ar waittime 124Specify the delay time between probes. 125.El 126.Pp |
127This program prints the route to the given destination and the round-trip |
128time to each gateway, in the same manner as traceroute. 129.Pp 130Here is a list of possible annotations after the round-trip time for each gateway: |
131.Bl -hang -offset indent |
132.It !N |
133Destination Unreachable - No Route to Host. |
134.It !P |
135Destination Unreachable - Administratively Prohibited. |
136.It !S |
137Destination Unreachable - Not a Neighbour. |
138.It !A |
139Destination Unreachable - Address Unreachable. |
140.It !\& |
141This is printed if the hop limit is <= 1 on a port unreachable message. 142This means that the packet got to the destination, 143but that the reply had a hop limit that was just large enough to 144allow it to get back to the source of the traceroute6. 145This was more interesting in the IPv4 case, 146where some IP stack bugs could be identified by this behaviour. 147.El 148.\" --- 14 unchanged lines hidden --- |
