After our vendors have setup a certain test environment, we need to go in to perform connectivity testing between PC to servers and also between servers.

The problem is that we run a range of tests to telnet between 2 nodes on several ports and this is a manual and rather tedious process.

Does anyone know of a small tool or script that I can take input on the range of ports to be test and will run an automated range of testing against those ports? All I need to do is to validate whether a TCP connection can be established from the source PC / server to the target server IP address / port.

Thanks, Wong
