Use Traceroute

Traceroute is often used for network troubleshooting. By showing a list of routers traversed, it allows you to identify the path taken from your computer to reach a particular destination on the network. It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this, it will tell you how long each 'hop' from router to router takes. This can help identify routing problems or firewalls that may be blocking access to a site.

• To perform a traceroute on an IP address or hostname:

1. Choose Operation > Network Interfaces > Traceroute.
2. Enter the IP address or hostname of the target you wish to check in the Traceroute Target field.
3. Select: Optional.
   

   Option	Description
   Verbose	Verbose output, which lists received ICMP packets other than TIME_EXCEEDED and UNREACHABLEs.
   No DNS Resolution	Does not resolve addresses to host names.
   Use ICMP (vs. normal UDP)	Use ICMP ECHO instead of UDP datagrams.

4. Type values for how many hops the traceroute command will use in outgoing probe packets (default is 30), the UDP destination port to use in probes (default is 33434), and the size for the traceroute packets. If left blank, defaults will be used. Optional.
5. Click Traceroute in the bottom right-hand corner of the window.
6. Press Ctrl+C or Ctrl+Q to terminate the traceroute session. A Return? prompt appears; press Enter to return to the Traceroute menu. The Return? prompt also appears when Traceroute terminates due to “destination reached” or “hop count exceeded” events occur.
