python批量修改ssh密码

由于工作需要本文主结合了excel表格，对表格中的ssh密码进行批量修改

以下是详细代码（python3）：

#!/usr/bin/env python
#-*-coding:utf-8-*-

import paramiko
import socket
import pandas as pd

def demo(Ip,user,old_password,new_password):
    # 建立一个sshclient对象
    ssh = paramiko.SSHClient()
    # 允许将信任的主机自动加入到host_allow 列表，此方法必须放在connect方法的前面
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    # 调用connect方法连接服务器
    #如果远程执行命令错误信息是b'the input device is not a TTY\n' 去掉docker exec -it 中的t就好了
    try:
        ssh.connect(hostname=Ip, port=22, username=user, password=old_password,timeout=5)
        #ubuntu修改密码两种方法
        #方法一
        # command1 = "echo '%s:%s' | chpasswd"%(user,new_password)
        # stdin, stdout, stderr = ssh.exec_command(command1)
        # out, err = stdout.read(), stderr.read()
        # if err != '':
        #     print(err)
        #
        # else:
        #     print(out)
        # # 关闭连接
        # ssh.close()
        #方法二
        command = "passwd %s" %(user)
        stdin, stdout, stderr = ssh.exec_command(command)
        #\n模拟回车 输两次密码
        stdin.write(new_password + '\n' + new_password + '\n')
        out, err = stdout.read(), stderr.read()
        successful = 'password updated successfully'
        #print(out,err)
        if successful in str(err):
            print(Ip + " 密码修改成功！")
        else:
            print('\033[31m错误：\033[0m' + str(err))
            print(Ip + " 密码修改失败！")
        # 关闭连接
        ssh.close()
    except paramiko.ssh_exception.AuthenticationException as e:
        print(Ip + ' ' + '\033[31m账号密码错误!\033[0m')
        with open('nossh.txt','a') as f:
            f.write(Ip + '\n')
    except socket.timeout as e:
        print(Ip + ' ' + '\033[31m连接超时！\033[0m')
        with open('timeoutssh','a') as f:
            f.write(Ip + '\n')

def Red_Excel(IP):
    import sys
    import time
    file = r'E:\xxx.xlsx'
    pd.set_option('display.max_columns', None)
    pd.set_option('display.max_colwidth', 1000)
    n = pd.read_excel(file,sheet_name='xxx')   #表格中的sheet名
    #print(n.values)
    #显示含某字段的特定行
    n1 = (n.loc[n['IP']==IP])
    if not n1.empty:
        n2 = n1.values
        ip = n2[0][1]
        user = n2[0][4]
        password_old = n2[0][5]
        password_new = n2[0][22]
        houtai = n2[0][16]
        print('IP：%s 账号：%s 旧密码：%s 是否后台：%s 新密码：%s' % (ip, user, password_old, houtai,password_new))
        demo(ip,user,password_old,password_new)
    else:
        print('记录表无此IP！')

if __name__ == "__main__":
    with open('ip.txt') as f:
        for i in f:
            ip = i.split('\n')[0]
            Red_Excel(ip)

此代码可以适当修改，进行单独的ssh密码修改。
