What Program Has This Port Open
How do I associate an open port with a running program?
eg: what is listening on port 22?# lsof -i :22 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME sshd 1318 root 3u IPv4 2444 TCP *:ssh (LISTEN) sshd 7665 root 4u IPv4 166534123 TCP netbackup:ssh->router:918 (ESTABLISHED) sshd 19710 root 4u IPv4 554877146 TCP netbackup:ssh->router:853 (ESTABLISHED)
# lsof -i :smtp COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME sendmail 25860 root 4u IPv4 66767220 TCP *:smtp (LISTEN)
# ss -tln State Recv-Q Send-Q Local Address:Port Peer Address:Port Process LISTEN 0 4096 127.0.0.1:199 0.0.0.0:* LISTEN 0 128 0.0.0.0:22 0.0.0.0:* LISTEN 0 128 [::]:22 [::]:*
- -l means listen
- -t means tcp ports
- -n means show numbers rather than names

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
