I had to backport in a command line sanitizer from shlex.quote so that python2 would function correctly with no shell injection.

This code should let you see what and how to use this.

#!/usr/bin/env python2
import pexpect
import getpass
from pexpect import pxssh

s = pxssh.pxssh()
hostname = raw_input('hostname: ')
username = raw_input('username: ')
password = getpass.getpass('password: ')


ssh_tunnels = {
'local':['2424:localhost:22'],
'remote':['2525:localhost:22']
}


s.login(hostname, username, password, ssh_key=True, ssh_tunnels=ssh_tunnels)
s.sendline('w')
s.prompt()
print('This should list the remote SSH server\'s logged in users')
print(s.before)

print('Testing Local SSH tunnel')
s2 = pxssh.pxssh()
s2.login('localhost', username, password, port=2424, ssh_key=True,quiet=False)
s2.sendline('w')
s2.prompt()
print('This should list the remote SSH server\'s logged in users plus our new connection.')
print(s2.before)

print('Testing Remote SSH tunnel')
s.login('localhost', username, password, port=2525, ssh_key=True,quiet=False,spawn_local_ssh=False)
s.sendline('w')
s.prompt()
print('This should list the local machine\'s logged in users')
print(s.before)
