How to check if a port is open on destination workstation

With Ping utility, you can check if a host is up and running, but you can’t ping ports on remote systems (Ping is using ICMP which resides one layer above transport layer protocols like TCP and UDP).

Solution:

You could use nmap to see whether ports are open or not

nmap -p <port> <domain>  eg
nmap -p 8080 yourDomain.com
