Ping a Port: To check if a port is open on a network, use the `telnet` command. For example, type `telnet [hostname] [port]` in your command line. Replace `[hostname]` with the IP address or domain name and `[port]` with the port number you want to check. This method works on most systems. Alternatively, for a more detailed scan, you can use a tool like `nmap`.
