I am trying to send data (plain text string) to a port at a remote computer using terminal utility. The string would be used to trigger something on the remote computer running a program that would listen to that specific port.
I used netcat command and tried a few combination of the following but can't seem to get the parameter right. Can someone point me out where am I doing wrong?
eddy-2:Desktop eddy$ nc IPADDRESS PORT > woc.txt
eddy-2:Desktop eddy$ nc IPADDRESS PORT < woc.txt
P.S: woc.txt contains plain text string of the said command.
Edit: I am trying to send a string from OSX to Windows XP where the specific port is open by default.
Added an edit to my post above. I am trying to send a string from OSX to Windows XP where the specific port is open by default. Must cat and netcat be running at the same time for this thing to work.
Note: I tried quite a number of other combination from man page but felt that I was missing something so I asked. – Scott – 2010-12-23T02:57:52.783
@Eddy - No. Run the server first (it will appear to hang while waiting for a client), client second. – new123456 – 2010-12-23T03:01:39.737
nc IPADDRESS PORT < woc.txt
should work fine. What do have listening on the server's PORT? – garyjohn – 2010-12-23T06:48:09.6731@Eddy: Your server command is missing a
-p
. It should benc -l -p PORT < woc.txt
. Also, I understood new123456 to want to send the contents of woc.txt to the server. – garyjohn – 2010-12-23T06:53:20.340@garyjohn - Correct. Quoting Eddy: woc.txt contains plaintext string of the said command – new123456 – 2010-12-23T14:29:44.437
