This article shares the node.js port forwarding implementation code for your reference. The specific content is as follows
#!/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);The above is all about this article, I hope it will be helpful to everyone's learning.
