Python-使用pexpect / pxssh失败

Question

i'm pretty new with python and i'm trying to make a simple ssh session and run a simple command. i know that i can use "paramiko" but i decide to use pexpect/pxssh and i installed the last version.

my code:

#!/usr/bin/env python

from pexpect import *
import pexpect
import pxssh
import getpass
import time
import os

try:
    s = pexpect.pxssh()
    hostname = raw_input('hostname:')
    username = raw_input('usernmae:')
    s.login((hostnmae,username,password)
    s.sendline ('uptime')
    s.prompt()
    print s.before
    s.sendline ('ls -l')
    s.prompt()
    print s.before
    s.logout()
except pxssh.ExceptionPxssh, e:
    print "pxssh failed"
    print str(e)

but it fails with the following:

$ python pssh.py
  File "pssh.py", line 15
    s.sendline ('uptime')
    ^
SyntaxError: invalid syntax

can someone please help?

Thanks a lot!

There are various problems in your code:

1. It should be

    s = pexpect.pxssh.pxssh() 

2. Check for extra "(" and variable hostname on line.

    s.login((hostnmae,username,password) 

3. And you need password for the ssh before above line.

     import getpass() password = getpass.getpass()
