perl 利用Net::SSH::Expect模块批量修改服务器密码

如果以下脚本可以批量修改服务器的密码，并且导出随机生成的密码

首先需要安装Net::SSH::Expect

安装方法：

#cpan

cpan>install  Net::SSH::Expect

然后一路回车

#!/usr/bin/perl

use strict;
use warnings;
use Net::SSH::Expect;

my @ssh_list;
my @array_list=(0..9,'a'..'z');# 生成随机种子
my $new_user_pass;
while (<>) {

$new_user_pass=join '',map{$array_list[int rand @array_list]}0..7;#生成随机密码 0..7表示8位密码
                @ssh_list=split/\s+/,$_;
        print $ssh_list[0]."正在修改密码\n";
        &ssh_test( "$ssh_list[0]","$ssh_list[1]","$ssh_list[2]","$ssh_list[3]" );
}

sub ssh_test() {
        my ( $host,$port,$user,$pass ) = @_;
        my $ssh = Net::SSH::Expect->new(
                host                => $host,
                port                => $port,
                password        => $pass,
                user                => $user,
                no_terminal => 0,
                raw_pty         => 1,
                timeout         => 6,
        );

        open FI,">>    /home/mcshell/newuser.txt" or die $!;##新密码所放的位置
        print FI "-" x 80,"\n";

        $ssh->debug(0);
        $ssh->run_ssh() or die "SSH process Couldn't start: $!";

        $ssh->waitfor( '\(yes\/no\)\?$',2 ); #交互式修改密码，给予2秒的时间
        $ssh->send("yes\n");
        $ssh->waitfor( 'password:\s*$/',2);
        $ssh->send("$ssh_list[3]");

        $ssh->send("su - root");                                 #    其实这里我本来的用户不是root，为了更好的扩展
        $ssh->waitfor( 'Password:\s*$',2 );#    经常服务器不容许root直接登录的，所以要用其他
        $ssh->send("$ssh_list[3]"); #用户来切换root
        $ssh->waitfor( '#\s*',2 );


        $ssh->send("passwd $ssh_list[2]");

        $ssh->waitfor( 'password:\s*$',2 );
        $ssh->send("$new_user_pass");

        $ssh->waitfor( 'password:\s*$',2 );
        $ssh->send("$new_user_pass");
        $ssh->waitfor( '#\s*',2 );
        print FI "$host\t$port\t$user\t$new_user_pass\n";
        $ssh->close();

        close FI;
        print "修改完成\n";
        print "-" x 30,"\n";
}

使用方法：

[root@MysqLmaster ~]# cat oldpasswd.txt
192.168.1.91        22            root        fmnuy5ci
192.168.1.95        22            root        bortv8bb


[root@MysqLmaster ~]# ./sshpwd.pl oldpasswd.txt
192.168.1.91正在修改密码
修改完成
------------------------------
192.168.1.95正在修改密码
修改完成
------------------------------

查看新生成的密码文件

[root@MysqLmaster ~]# cat /home/mcshell/newuser.txt -------------------------------------------------------------------------------- 192.168.1.91        22            root        9f8mu1gs -------------------------------------------------------------------------------- 192.168.1.95        22            root        1p2p2y0y
