This is easily doable with modules like ssh2, xterm, and socket.io.
Here's an example:
npm install ssh2 xterm socket.io- Create
index.html:
<html>
<head>
<title>SSH Terminal</title>
<link rel="stylesheet" href="/src/xterm.css" />
<script src="/src/xterm.js"></script>
<script src="/addons/fit/fit.js"></script>
<script src="/socket.io/socket.io.js"></script>
<script>
window.addEventListener('load', function() {
var terminalContainer = document.getElementById('terminal-container');
var term = new Terminal({ cursorBlink: true });
term.open(terminalContainer);
term.fit();
var socket = io.connect();
socket.on('connect', function() {
term.write('
*** Connected to backend***
');
// Browser -> Backend
term.on('data', function(data) {
socket.emit('data', data);
});
// Backend -> Browser
socket.on('data', function(data) {
term.write(data);
});
socket.on('disconnect', function() {
term.write('
*** Disconnected from backend***
');
});
});
}, false);
</script>
<style>
body {
font-family: helvetica, sans-serif, arial;
font-size: 1em;
color: #111;
}
h1 {
text-align: center;
}
#terminal-container {
width: 960px;
height: 600px;
margin: 0 auto;
padding: 2px;
}
#terminal-container .terminal {
background-color: #111;
color: #fafafa;
padding: 2px;
}
#terminal-container .terminal:focus .terminal-cursor {
background-color: #fafafa;
}
</style>
</head>
<body>
<div id="terminal-container"></div>
</body>
</html>
- Create
server.js:
var fs = require('fs');
var path = require('path');
var server = require('http').createServer(onRequest);
var io = require('socket.io')(server);
var SSHClient = require('ssh2').Client;
// Load static files into memory
var staticFiles = {};
var basePath = path.join(require.resolve('xterm'), '..');
[ 'addons/fit/fit.js',
'src/xterm.css',
'src/xterm.js'
].forEach(function(f) {
staticFiles['/' + f] = fs.readFileSync(path.join(basePath, f));
});
staticFiles['/'] = fs.readFileSync('index.html');
// Handle static file serving
function onRequest(req, res) {
var file;
if (req.method === 'GET' && (file = staticFiles[req.url])) {
res.writeHead(200, {
'Content-Type': 'text/'
+ (/css$/.test(req.url)
? 'css'
: (/js$/.test(req.url) ? 'javascript' : 'html'))
});
return res.end(file);
}
res.writeHead(404);
res.end();
}
io.on('connection', function(socket) {
var conn = new SSHClient();
conn.on('ready', function() {
socket.emit('data', '
*** SSH CONNECTION ESTABLISHED ***
');
conn.shell(function(err, stream) {
if (err)
return socket.emit('data', '
*** SSH SHELL ERROR: ' + err.message + ' ***
');
socket.on('data', function(data) {
stream.write(data);
});
stream.on('data', function(d) {
socket.emit('data', d.toString('binary'));
}).on('close', function() {
conn.end();
});
});
}).on('close', function() {
socket.emit('data', '
*** SSH CONNECTION CLOSED ***
');
}).on('error', function(err) {
socket.emit('data', '
*** SSH CONNECTION ERROR: ' + err.message + ' ***
');
}).connect({
host: '192.168.100.105',
username: 'foo',
password: 'barbaz'
});
});
server.listen(8000);
- Edit the SSH server configuration passed to
.connect() in server.js
node server.js- Visit http://localhost:8000 in your browser
