python,pexpect登录ssh并

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

root::1.1.1.1::ls&&date

root::2.2.2.2::ls&&date
