python ssh 连接
python pexpect ssh 远程登录服务器的方法使用了python中的pexpect模块，在测试代码之前，可输入python进入交互界面，输入help('pexpect')，查询是否本地含有pexpect模块。
如果没有，linux系统输入 easy_install pexpect便可自动安装。
测试代码，连接127.0.0.1
下面是我手动连接127.0.0.1， 发现只有在首次使用ssh连接127.0.0.1时，需要输入yes or no ，而后再次使用ssh ,则不需要再次输入yes
直接输入密码即可。
后续测试代码是二次链接，无需查询是否需要输入yes or no

可以用pxssh模块更简单来完成ssh的连接

from pexpect import pxsshdef send_command(s, cmd): s.sendline(cmd) s.prompt() print s.beforedef connect(host, user, password): try: s = pxssh.pxssh() s.login(host, user, password) return s except: print "error" exit(0)def main(): s = connect('127.0.0.1', 'root', '15110506010') send_command(s, 'whoami')if __name__ == '__main__': main() |
批量连接肉鸡。
