Hi,

I'm curious why you think you need a port number for this ping extension. Ping is a diagnostic procedure that can be used with any port, and placing payload into the packet sent to elicit the ICMP response doesn't change that.

In other words, ping isn't a protocol.

Also, with regards to TCP ping, do you envision your payload data to be placed inside the SYN?
