This is one of the beginner sockets code that anyone learns after he
learns basic syntax and looping.
Doing this was easiest in python, perl,lua.
But now you have node.js, the serverside javascript engine based on
Google's V8 virtual machine.
So here goes. I had to do this for a project.
I need a simple TCP server written in node.js like this:
#!/usr/local/bin/node
var sys = require('sys'); /* system calls */
var exec = require('child_process').exec;
// server
require('net').createServer(function (socket) {
console.log("connected");
socket.on('data', function (data) {
str = "date";
console.log(str);
exec(str);
console.log(data.toString());
});
})
.listen(2000);
Then the client:
#!/usr/local/bin/node
var s = require('net').Socket();
s.connect(2000, '127.0.0.1');
s.write('I got mail');
s.end();
Simple sockets based communication between two machines on
the Internet.
Sockets coding continues to amuse me.
