node.js实现端口转发
本文为大家分享的是node.js端口转发实现代码，供大家参考，具体内容如下
#!/sbin/node
var net = require('net');
function proxyPort(srcport,destServer,destport)
{
var server = net.createServer(function(c) { //'connection' listener
c.on('end', function() {
console.log('src disconnected');
});
var client = net.connect({port: destport,host:destServer},function() { //'connect' listener
console.log('ok....');
c.on('data', function(data) {
console.log(data.length);
client.write(data);
});
});
client.on('error', function(err) {
console.log("dest=" + err);
c.destroy();
});
c.on('error', function(err) {
console.log("src" + err);
client.destroy();
});
client.on('data', function(data) {
c.write(data);
});
client.on('end', function() {
console.log('dest disconnected ');
});
});
server.listen(srcport, function() { //'listening' listener
console.log('server bound' + srcport);
});
}
var params = process.argv;
if(params.length != 5){
console.log("node port.js srcport destserver destport ");
return;
}
proxyPort(params[2],params[3],params[4]);
console.log(process.argv);
