优雅地乱玩Linux-6-Chrome端SSH插件
最近注册了个AWS，免费一年，一年内可以各种乱玩~
从自己的电脑连接云主机一般需要SSH这样的东西。既然有如此机会，干脆系统性学习下SSH：
Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. The best known example application is for remote login to computer systems by users.
SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2.
The most visible application of the protocol is for access to shell accounts on Unix-like operating systems, but it sees some limited use on Windows as well. In 2015, Microsoft announced that they would include native support for SSH in a future release.
SSH是一种加密的网络协议，用于在非安全网络下建立到网络设备的安全链接。SSH被广泛用于远程计算机的命令执行，类似VPS，云主机等设备都需要SSH进行操作。
SSH连接
建立SSH连接有多种方式：
Linux/Unix系统下Terminal直接创建Linux/Unix/Windows系统下使用三方软件创建浏览器中创建，需要JRE，并且很多浏览器已经不支持Chrome中使用插件创建
主要说说Chrome中插件的方案
Secure Shell：在Chrome中使用SSH
首先下载个插件：https://chrome.google.com/webstore/detail/secure-shell/pnhechapfaindjhompbnflcldabbghjo?hl=en-US
基本上看到就知道如何使用了
EC2在Secure Shell中的认证问题: NaCl plugin exited with status code 255
EC2一般使用.pem的Private Key进行认证，但是在使用Secure Shell中经常会遇到个问题：
Host key verification failed.
NaCl plugin exited with status code 255.
(R)econnect, (C)hoose another connection, or E(x)it?
看很多讨论说原因是：SSH需要个Public Key，但是我们只有一个Private Key
很多Solution说需要生成一个Publick Key之类的，但是实际上Public Key这儿并没有任何要求，我们只需要将自己的.pem复制一份然后扩展名改成.pub即可
比如自己的Private Key是123.pem那么复制一份然后命名为123.pen.pub， 然后Import的时候都选中即可
这看起来是个偏方不过确实有用
