Traceroute
Where ping will only tell you if it reached its destination and came back successfully, traceroute will show each step of its journey to its destination and how long each step takes. If ping finds an outage between two points, traceroute can be used to locate exactly where the problem is.
To use traceroute on an Windows PC
1. Go to a DOS prompt. Typically you go to Start > Run, enter “cmd” and select OK.
2. Enter “tracert fortinet.com” to trace the route from the PC to the Fortinet website.
To use traceroute from an Apple computer
1. Open the Terminal.
2. Enter traceroute fortinet.com.
3. The terminal will list the number of steps made. Upon reaching the destination, it will list three asterisks per line. Press Control+C to end the attempt.
To use traceroute on a Linux PC
1. Go to a command line prompt.
2. Enter “/bin/etc/traceroute fortinet.com”.
The Linux traceroute output is very similar to the MS Windows traceroute output.
