Re: Cal you telnet to an IBMi host on ports that you think you will be using for MQ and Connect DIrect if the host doesn't have the services running?

Hello Laurence,

I'm not sure what information telnet can provide

See my second message from yesterday. There I explained the details.

so the firewall rules appeared to be fine but they were still getting connection refused. That led me to consider nobody was listening.

My daily routine (also administering Firewalls for customers) is quite different. Experience proves that most errors are not a firewall problem. Before I even consider logging into the firewall for checking, I request a netstat check. Saved me a lot of unnecessary work.

:wq! PoC
