python,pexpect登录ssh并

2023-01-31 03:01:36 python pexpect 登录

1、 安装python的Pexpect模块

wget Http://jaist.dl.sourceforge.net/project/pexpect/pexpect/Release%202.3/pexpect-2.3.tar.gz

tar xzf pexpect-2.3.tar.gz

cd pexpect-2.3

Python setup.py install

2、 执行脚本

可以登录到机器执行一些简单的命令等。。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import pexpect
from getpass import getpass
passwd = getpass()
def ssh_cmd(user,ip, cmd):
        ssh = pexpect.spawn('ssh %s@%s "%s"' % (user,ip,cmd))
        try:
                i = ssh.expect(['passWord:', 'continue connecting (yes/no)?'], timeout=5)
                if i == 0 :
                        ssh.sendline(passwd)
                elif i == 1:
                        ssh.sendline('yes')
                        ssh.expect('password: ')
                        ssh.sendline(passwd)
        except pexpect.EOF:
                print "EOF"
        except pexpect.TIMEOUT:
                print "TIMEOUT"
        else:
                r = ssh.read()
                print r
        ssh.close()

if __name__ == '__main__':
        file=open("/root/python/filelist",'r')
        a = file.read()
        file.close()
        for host in a.split("\n"):
                if host:
                        user,ip,cmd = host.split("::")
                        print "-- %s run:%s --" % (ip, cmd)
                        ssh_cmd(user,ip,cmd)

more /root/python/filelist
