In a network model, there are no compatability issues between programming languages, only protocols.

Is any data transferred at all? You might also want to try changing the number of bytes to read() to 1, and putting it inside of a while() loop. Automatically print out received data. Maybe even set up a sniffer to see if the client is sending data, though that shouldn't be necessary. I don't believe your problem is in either the read() nor the print()..
