Here is a short post to check port [TCP/UDP] connectivity from a Linux server. A TCP/IP network connection may be either blocked, dropped, open, or filtered. These actions are generally controlled by the IPtables firewall the system uses and is independent of any process or program that may be listening on a network port. Test jBoss port 8080 with curl. This scenario shows that connection is refused (probably because there’s no service running on that port). IMPORTANT: you would probably get a different message if firewall blocks the 8080 port. Connection refused is a clear sign that port is accessible, but nothing’s responding on it. The Test-NetConnection cmdlet displays diagnostic information for a connection. It supports ping test, TCP test, route tracing, and route selection diagnostics. Depending on the input parameters, the output can include the DNS lookup results, a list of IP interfaces, IPsec rules, route/source address selection results, and/or confirmation of connection establishment.

To instruct Nmap to scan UDP ports instead of TCP ports (the –p switch specifies ports 80, 130, and 255 in this example): nmap –sU –p 80,130,255 192.168.0.1. Run a fast scan on the target system, but bypass host discovery. (Host discovery uses ping, but many server firewalls do not respond to ping requests. This option forces the test On the server itself, use netstat -an to check to see which ports are listening. From outside, just use telnet host port (or telnet host:port on Unix systems) to see if the connection is refused, accepted, or timeouts. On Windows 7 or Windows Vista the default option 'telnet' is not recognized as an internal or external command, operable program or batch file.
