5var tunnel = require('reverse-tunnel-ssh');
6tunnel({
7  host: 'tunneltest.com',
8  username: 'root',
9  dstHost: '0.0.0.0', // bind to all IPv4 interfaces
10  dstPort: 8000,
11  //srcHost: '127.0.0.1', // default
12  //srcPort: dstPort // default is the same as dstPort
13}, function(error, clientConnection) {

21  username: 'somebody',
22  dstHost: '0.0.0.0', // bind to all IPv4 interfaces
23  dstPort: 0, // dynamically choose an open port on tunneltest.com
24  //srcHost: '127.0.0.1', // default
25  srcPort: 8000, // must be specified if dstPort=0
26}, function (error, clientConnection) {
