In order to see the log messages of the server, start it with.

This is a JSON with three attributes: (i) a key-value pair type: Error, to allow the client to tell that an error has occurred, (ii) a code, which can be used to uniquely identify the type of error and (iii) a message, which offers some human-readable details.

If the conditions satisfy then the while loop goes on doing its work in each iteration,however if any condition fails then the client side program ends but at server side it shows an infinte loop running without any exit.

But the above are some of the very classic ways of interprocess communication.

So this is also an inter process communication but the technique through which they communicate with each other is SOCKETS, which is the focus of this article.

To be a bit precise, a socket is a combination of IP address and port on one system.

So on each system a socket exists for a process interacting with the socket on other system over the network.

A combination of local socket and the socket at the remote system is also known a Four tuple or 4-tuple.

Each connection between two processes running at different systems can be uniquely identified through their 4-tuple.

For connection oriented reliable connections, the default protocol used is TCP.

The details include, the familydomain, the interface to listen on(in case the system has multiple interfaces to network) and the port on which the server will wait for the client requests to come.

We might soon be posting an article on the theoretical aspect of the TCP protocol.

We need to send the IP address of the server as an argument for this example to run.

If you are running both server and client example on the same machine for testing purpose, use the loop back ip address as shown above.

Socket programming is exactly what I wanted to take a look at next.

I would like to hear about new systemd in Linux World from GeekStuff.

One suggestion here (for the coding style, nothing related to Socket programming).

I know this is not a coding tutorial, but just mentioned hope you dont mind.

For example, if the client sends the server 9, then that means that the client is going to send the server 9 integer numbers.

I wanted to see if I can get the date and time from my windows and display them on ubuntu.

I compiled the code and it gave no errors, but when I wrote.Socket-1 it gave me this error: Connection Failed.

I have a question: how can we let the server run forever and continuously sendreceive data tofrom the client I.e., is there anyway to not close the socket Something similar to serveforever() in Python.

Can i send an alarmtrap from server to client for a specific task without the client querying for anything.

I want to ask about server performs some computational task on behalf of Clients and response to him like as example client send two integers to server and server add those number and output response to server.

Ive been trying to run the server and client on the same machine, so Ive been using the loopback address.
