traceroute
The traceroute command displays the route a packet travels to reach a remote host on the network. The syntax is
> traceroute [-r] host
Important Flags -i : Specifies a network interface for outgoing packets.
This is useful in system with more than one network interface.
-r : Bypasses normal routing tables and attempts to send directly to an attached host.
For example
> traceroute -r 152.106.50.27
The output could be
Tracing route to zeus.rau.ac.za [152.106.50.27] over a minimum of 30 hops
1 3ms 3ms 4ms xylan-40.rau.ac.za [152.106.240]
2 14ms 3ms 5ms 152.106.9.241
3 12ms 26ms 2ms zeus.rau.ac.za [152.106.50.27]
Another example is
traceroute -r issc.rau.ac.za
This command is called tracert in Windows.
