    if (err) throw err;
    stream.on('data', function(data, extended) {
        console.log((extended === 'stderr' ? 'STDERR: ' : '')
                   + data);

     console.log('Connection :: close');
   });        
   c.connect({
     host: '127.0.0.1',
     port: 22,
     username: 'test',
     password: 'test'
   });

Or is there any suggestion to execute tail -f using nodejs?

The easiest way to do this is to use a form like this for your command line: 'tail -f test.txt & read; kill $!'.

Then when you want to kill the process, simply stream.write('\n');
