Ping a TCP Port

As far as I know ping cannot be used to test a port, it just tests if the actual node is live.
For this sort of test you should use telnet to verify that the port is open.
eg. telnet 192.168.1.1 25 would telnet to the SMTP port.

The following is PING under windows:-
Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
[-r count] [-s count] [[-j host-list] | [-k host-list]]
[-w timeout] destination-list
Options:
-t Ping the specified host until stopped.
To see statistics and continue - type Control-Break;
To stop - type Control-C.
-a Resolve addresses to hostnames.
-n count Number of echo requests to send.
-l size Send buffer size.
-f Set Don't Fragment flag in packet.
-i TTL Time To Live.
-v TOS Type Of Service.
-r count Record route for count hops.
-s count Timestamp for count hops.
-j host-list Loose source route along host-list.
-k host-list Strict source route along host-list.
-w timeout Timeout in milliseconds to wait for each reply.
In Linux/Unix I dont know.

You can't ping a port as ping and TCP operate at different layers.
You could however download a port scanner and scan for the port in question - that would seem to achieve the thing you're looking for.
Port scanners are two a penny so just Goggle for port scanner and you'll be spoilt for choice.

Is there a firewall blocking it somewhere?
