Ping server on a specific port

The ping command is used to check if the source computer can reach a specific destination computer. It’s a simple way to verify that a computer can communicate with another computer or network device.

The only drawback is that you can’t ping on specific ports, as Ping is using ICMP which doesn’t have the concept of ports. Ports belong to the transport layer protocols like TCP and UDP. However, you could use nmap to see whether ports are open or not:

nmap -p 80 example.com

The output will look like this:

nmap -p 80 google.de
