start the server, listen on port 7000~7099

./server 7000

run the client

./client 127.0.0.1 7000

The server will ouput message like this and quit:

connections: 153

It says the server can only accept 153 connections, it reaches the max-open-files limitation so it quit.

The client will output message like this:
