    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
