Is it possible to use tcptraceroute to probe a certain port? The documentation in the man pages seems to suggest that the '-p' port flag is for UDP, and when used with tcptraceroute, is for specifying the source port?
How do I specify the destination port? (eg. 443, or 500)
Thanks
man traceroute ; traceroute -T -p 443 www.example.com
not working for you?
