How to check if a port is open

[NickFitz]

Seriously people, a service has to be running on a particular port!!! If you cant Telnet to it then guess what, maybe no Telnet service running there, it doesn't mean the port is closed!

Telnet clients are frequently used to establish raw TCP sessions. This is how I am able to, for example, use a Telnet client to access my POP3 mailbox, or to access a web server and retrieve data using HTTP. Presumably this kind of usage is what the OP was referring to.

Which proves nothing, the OP had opened the PORTS... but to what? There is no way that being unable to Telnet to a port is proof that is closed!

Why?

Harbour masters control ports typically and would allow shipping to understand whether or not they could safely transit into or out of a port.

(Sheesh, a joke that needs to be explained = a highly tulip joke).

I started writing a helpful and explanatory reply based on my experience with TelNet and knowledge of where NickFitz is, but then I remembered:

Surely there is more to shipping, than knowing what docks are free in a port? But yeah it was a very good joke, no really it rocked. I mean if you have to explain a joke it must be awesome!
