Can someone please assist me with doing source port scanning with nmap? I've
read the MAN page and do not see this switch listed.

Is it --source-port <port number>?

Thanks

Hey there the option you need is -g, here is an example:

nmap -sS -O 192.168.0.0/16 -g 53

This will set the source port to 53, and use a standard synscan withhost detection.
