paramiko模块
模拟ssh远程登录的功能
1 #!/usr/bin/env python 2 #coding:utf-8 3 4 import paramiko 5 6 ssh = paramiko.SSHClient() 7 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 8 ssh.connect('192.168.30.241',22,'root','123456') 9 stdin,stdout,stderr=ssh.exec_command('ls') 10 print stdout.read() 11 ssh.close() 12 13 #用户名和密码连接
在paramiko-master源码包中修改文档，使其可以记录用户登录的输入记录。
