A python server-client chatter room application based on the works of https://gist.github.com/schedutron.
Major improvements: Error handling and stability.
Install python3 on both the server and your client PC.
On server (e.g. Ubuntu), first you need to open firewall and iptables for chatter listening port, default 33000.
To add iptables rule, run: iptables -I INPUT -p tcp --dport 33000 -j ACCEPT
then start server application: python3 chat_serv.py
On any windows client PC when you want to join the chatter room, just double-click chat_clnt.py or run: python chat_clnt.py.
