So I have a Telnet Server running (Example: 192.22.50.70:2300)

Now for Node Red all I want to do is send a "Telnet command" that will test to see if port 2300 is open on IP address 192.22.50.70 and return a simple "True or False".

I started this project a while back and moved away from it but now I need to again move forward, can someone help to get me started?

Thanks

TELNET is for interactive sessions. It isn't well suited to the kind of thing you appear to want to do. Depending on your OS, there are other tools that would serve you better.

If you are using a linux based system, you could try to use an `exec` node with a command like:

```auto
timeout 2 bash -c "</dev/tcp/192.22.50.70/2300"; echo $?

```

it will return 0 if successful.

I moved on to a different approach again, due to equipment (Hardware).

Thanks again.
