LAN server emulator application

Question

I am looking for a LAN server emulator application capable of doing the following:

• Can connect to it from another application via TCP/IP
• Can send some binary data to my applications

Of course I can write this part but I am looking for something ready. Any ideas?

Answer 1

netcat

nc -l -p 1234 < binary.dat

Then your application can connect to port 1234 on that computer to receive the binary data.

(You could test this with nc yourservername 1234 > received.dat)

Please update your question if you have in mind some specific platform, application or network protocol.
