To test connectivity, you can try telnet:

telnet 2195

If it is working, you should get a reply like this:

Connected to
Escape character is '^]'.
Use telnet. Use the following format, where #### is the port to connect to:

telnet ####

$ telnet 2195
Connected to
Escape character is '^]'.

If you get the Connected... message, then you successfully connected to that server and port.

Type quit to exit telnet, then try the next domain in your list.

EDIT: Gerwin beat me by 2 1/2 minutes!
