Watchroute is a continuous traceroute which continually pings and updates the list of possible hosts between you and a target system. IP addresses which are not present on the most recent route will be grayed out and denoted with an x in the TTL column. All IP addresses seen are pinged continually, with the three most recent results displayed.
Usage: watchroute [-d][-h ttl][-w ms] target
-d : Do not resolve DNS names
-h 8 : for instance, use a maximum ttl of 8
-w 2000 : for instance, use a timeout of 2000ms
-v : print version and exit
-n 5 : for instance, quit after 5 traceroutes
-r 3 : for instance, redact any hop with TTL <= 3
-s : suppress extra output
