Thanks Dennis. Hey..... I finally understand what ports are. Wikipedia told me. Am I correct in my understanding that tey are a connection between an ip address and a service?

/etc/services list common ports and services.  See man services.  Of
course, you can configure a service to run on a non-standard port.  In
the case of SSH (sftp is part of the SSH package) the port is configured
in /etc/ssh/sshd_config.

Nmap can be used to find open ports on a server but should only be used
if you understand the legal implications of its use.
