What is your server platform? There are php, perl, sh and I'm sure c#/.net code that can listen.

You can use the

netcat -ul 8811

command to listen to the UDP dump

On windows you can try:

netstat -an | find "UDP" | more

you might get an output like this:

  UDP    0.0.0.0:1234           *:*
  UDP    0.0.0.0:1235           *:*
  UDP    0.0.0.0:1236           *:*
  UDP    0.0.0.0:1237           *:*
  UDP    0.0.0.0:1238           *:*
  UDP    0.0.0.0:1239           *:*

feel free to grep the port

Running:

netstat -a -p UDP -b

can be helpful in determining what is attached to those ports.

This is really helpful: http://bansky.net/echotool/ https://github.com/PavelBansky/EchoTool

For server mode listening on UDP port 8811 run following command

C:\EchoTool> echotool /p udp /s 8811
