traceroute
It will print the route packets take to network host
Usage: traceroute [-adFIlnSvx] [-A address_family] [-c traffic_class]
[-f first_hop] [-g gateway [-g gateway ...]| -r] [-i iface]
[-L flow_label] [-m max_hop] [-P pause_sec] [-p port] [-Q max_timeout]
[-q nqueries] [-s src_addr] [-t tos] [-w wait_time] host [packetlen]
Some output symbol descriptions:
- ! the ttl (hop limit) value in the received packet is <= 1.
- !H host unreachable.
- traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 40 byte packets1 172.16.0.250 (172.16.0.250) 0.679 ms !H * 0.594 ms !H
- !X communication administratively prohibited.
- ICMP (ICMP6) unreachable code N.
- !F The associated gateway is broken.
- !N network unreachable.
- !P protocol unreachable.
- !S source route failed. It is likely that the gateway does not support source routing.
- !T unreachable for the specified TOS (type-of-service).
- !U source host isolated or precedence problem.
- !A host unreachable for a reason other than lack of an entry in the routing table.
- !B packet too big.
- !E destination is not a neighbor.
- !R unrecognized next header.
