滑铁卢战争是好是坏?(《悲惨世界》第十七章经典段落摘抄)

如果站在更高的层面看待滑铁卢战争,滑铁卢是一场反对君主制的胜利。它是欧洲对抗法国的胜利,是圣彼得堡、柏林、维也纳对抗巴黎的胜利。他是 1889 年 7 月 14 日,攻击了 1815 年的 3 月 20 日。过去一直是君主制度在不停地清理不屈不饶的 “法国自由革命稍乱”,就如同不知疲倦的水手永不停息地清理甲板,而如今波旁王朝以及其他君主制势力联合起来,推翻了这位叱咤风云了二十六年的伟大人物——拿破仑,拿破仑帝国是专制的,但由于现实的状况,现在皇帝将被迫选择让国家自由,帝国的宪法秩序不情愿地接受了滑铁卢的结果。

[工具] Shell 批量实现其他多台电脑可以免密码 SSH 本电脑

介绍

基本信息

作者:朱明宇
名称:批量实现其他多台电脑可以免密码 SSH 本电脑
作用:批量将其他多台电脑的公钥拷贝给本电脑

使用方法

1. 在此脚本的分割线内写入相应的内容
2. 给此脚本添加执行权限
3. 执行此脚本

脚本分割线里的变量

1. nm=192.168.4.0 #网段,网段必须为 C 类网段,请保证格式和前 3 个网络位一定正确
2. sip=51 #起始 ip,起始 IP 地址,IP 地址 的范围是 0-255
3. lip=51 #结束 ip ,结束 IP 地址,IP 地址 的范围是 0-255
4. pd=123456 #其他服务器的 root 远程登录密码
5. lpd=Taren1 #本机的 root 远程登录密码
6. lh=192.168.4.254 #本机 IP 地址

注意

1. 此脚本执行前必须要先保证执行本脚本的用户能无密码 ssh 远程这些远程服务器
2. 必须以 root 用户执行本脚本

脚本
