You want to test a network port, on a remote system - over TCP/IP. Maybe this is a new setup, or you want confirmation it is working. Perhaps the firewall rules have just been changed!

A nice small bit of Perl code that I’ve used thousands of times! In fact I’m running it in most of my production environments,
as a check that the a process is not only running - but also responding. Yep, you could just use telnet - but some systems have that taken off for security. Additionally it is n’t as easy to program telnet - I know, I know - you can with expect.

Here is just a one liner, but you can easily incorporate this into a script. perl -MIO::Socket -e '$socket=IO::Socket::INET->
new(Proto=>tcp,PeerAddr=>$ARGV[0],PeerPort=>$ARGV[1]);
if($@) { print "Failed: $@\n" } else { print "Succeed\n"; }' host port
