This is my first time with node js. I am trying to get the client to connect to the server and maintain the connection without closure.
This is all hosted in an ubuntu server edition hosted in a virtualbox.
I had checked that the server is actually listening to the port 5000 using netstat -ant
Websockets is also available on my browser.
I get the following output with error
Echo server dot come
192.168.1.107
node.js:134
throw e; // process.nextTick error, or 'error' event on first tick
^
Error: EPIPE, Broken pipe
at Socket._writeImpl (net.js:159:14)
at Socket._writeOut (net.js:450:25)
at Socket.write (net.js:377:17)
at Socket.ondata (stream.js:36:26)
at Socket.emit (events.js:81:20)
at Socket._onReadable (net.js:678:14)
at IOWatcher.onReadable [as callback] (net.js:177:10)
and if i call socket.end() on the server on connection event handler i get a disconnecting client. My question is how to establish a stable connection using this code, what do i have to change or i am doing wrong here? pulling my hair out - thanks in advance!
