Output

Run server.js file as-

~$ node server.js

Server listening on 127.0.0.1:6969
CONNECTED: 127.0.0.1:42478
DATA RECEIVED: 127.0.0.1: Hello
DATA RECEIVED: 127.0.0.1: Hello

Run client.js as-

~$ node client.js -t 3000 -i 1000                      //here -t is timeout in miliseconds and -i is interval in miliseconds 

prompt: message:  Hello                                //Send data to server
CONNECTED TO: 127.0.0.1:6969
Remaining:2
Remaining:1
Remaining:0
Connection closed

#Explaination

In client.js output after prompt message 'Remaining:2' is used just to show interval wait time. Consider timeout is 3000 Milisec i.e 3 Sec and interval is 1000 milisec i.e 1 seconds, then client will send prompt message after every 1 sec and till 3 sec and server will echo the same message.
