Is this server IP + PORT reachable from my server? (using Telnet)

Question

I am not so into networking and I have the following doubt. I have to test if a specific port on a server it can be reached from another server (or if there is something that is blocking the request as a firewall).

I am trying to use telnet on this port:

telnet SERVER_IP PORT.

This is what I am obtaining:

So what it means? Is it reachable? The thing that makes me suspicious is this Trying SERVER_IP...

Answer 1

This means that it is trying to connect.

A successful connection message would look like:

Connected to www.example.net.
Escape character is '^]'.

If you wait long enough for unsuccessful connection, you might get error messages like:

Could not open connection to the host, on port 1111: Connect failed
telnet: Unable to connect to remote host: Connection refused

Question: Do you really have a point . after the port number?
