traceroute 161
hop count of 0 or 1. This can occur if the destination uses the maximum
hop count value from the arriving packet as the maximum hop count in
its ICMP reply. The reply does not arrive at the source until the destination
receives a traceroute packet with a maximum hop count equal to the
number of hops between the source and destination.
An asterisk (*) indicates that the timeout period expired before MSS
received a Time Exceeded message for the packet.
If Traceroute receives an ICMP error message other than a Time Exceeded
or Port Unreachable message, MSS displays one of the error codes
described in Table 36 instead of displaying the round-trip time or an
asterisk (*).
Table 36 describes the traceroute error messages.
