This example imports the getpass module, which will prompt the host, user, and password, establish the connection, and run some commands on a remote server.

You can find the following code in the filename: pxsshConnection.py:

import pxssh
import getpass

try: 
    connection = pxssh.pxssh()
    hostname = input('hostname: ')
    username = input('username: ')
    password = getpass.getpass('password: ')
    connection.login (hostname, username, password)
    connection.sendline ('ls -l')
    connection.prompt()
    print(connection.before)
    connection.sendline ('df')
    connection.prompt()
    print(connection.before)
    connection.logout()
except pxssh.ExceptionPxssh as e:
    print("pxssh failed on login.")
    print(str(e))

We can create specific methods to establish the connection and send commands.

You can find the following code in the filename: pxsshCommand.py:

#!/usr/bin/python
# -*- coding: utf-8 -*-
import pxssh

hostname = 'localhost'
user = 'user'
password = 'password'
command = 'df -h'

def send_command(ssh_session, command):
    ssh_session.sendline(command)
    ssh_session.prompt()
    print(ssh_session.before)

def connect(hostname, username, password):
 try:
     s = pxssh.pxssh()
     if not s.login(hostname, username, password):
         print("SSH session failed on login.")
     return s
 except pxssh.ExceptionPxssh as e:
     print('[-] Error Connecting')
     print(str(e))

def main():
    session = connect(host, user, password)
    send_command(session, command)
    session.logout()

if __name__ == '__main__':
    main()
