Hi,

is it possible to check to see if I can connect to a particular port on another machine?

Thanks.

Yes. Typically you

(a) try and use the application you intend to use and that knows the protocol for that port

or

(b) use "telnet <hostname> <port>" to confirm connectivity.

Most of the cases this might not be possible as, telnet-d might not have been enabled due to security reasons where login is permitted only through ssh-d

if you have Python: you can use this script

I am not referring to using telnetd, I am refering to the client telnet program to test for any specific active listening port.
