Hi Chip, I don't know what is wrong but a couple small directions to try:
Does "iptables -L" confirm that the firewall rules have been flushed out? Can you rule out any potential connection to your socket code by reproducing the problem with netcat/nc? On the server: nc -l -p PORT HOST On the client: echo "Hello World" | nc PORT HOST If it works, you should see the message printed by the server and not get any error. If this also fails, say any error messages and it may help others reproduce the problem themselves. Luck, -Brett.
