stream.js

'use strict';
var fs = require('fs')
var SSH = require('ssh2')

var conn = new SSH()
conn.on('ready',function(){
  conn.exec('cat .ssh/known_hosts',function(err,stream){
    stream.setEncoding('utf-8')
    stream.on('readable',function(){
      console.log('stream readable')
      console.log(stream.read())
    })
    stream.on('end',function(){
      console.log('called end')
    })
    stream.on('close',function(){
      console.log('called close')
    })
    stream.on('finish',function(){
      console.log('called finish')
    })
  })
})
conn.connect({
  host: 'localhost',
  username: 'root',
  privateKey: fs.readFileSync('/path/to/key')
})
