Traces the route taken by packets to reach network host. traceroute attempts tracing by launching UDP probe packets with a small TTL (time to live), then listening for an ICMP "time exceeded" reply from a gateway.
host is the destination hostname or the IP number of host to reach.
packetsize is the packet size in bytes of the probe datagram. Default is 38 bytes.
Turn on socket-level debugging.
Set the TTL for the first probe packet.
Set the "don't fragment" bit.
Set a loose gateway.
Specify the interface for outgoing packets.
Set maximum time-to-live used in outgoing probe packets to
max-ttl hops. Default is 30 hops.
Show numerical addresses; don't look up hostnames. (Useful if DNS is not functioning properly.)
Set base UDP port number used for probe packets to
port. Default is (decimal) 33434.
Specify the protocol to use: UDP, TCP, GRE or ICMP.
Set number of probe packets for each time-to-live setting to the value
n. Default is 3.
Bypass normal routing tables and send directly to a host on an attached network.
src_addr as the IP address that will serve as the source address in outgoing probe packets.
Set the type-of-service in probe packets to tos(default 0). The value must be a decimal integer in the range 0 to 255.
Verbose; received ICMP packets (other than
PORT_UNREACHABLE) will be ...
