優雅地亂玩Linux-6-Chrome端SSH插件

最近注冊了個AWS，免費一年，一年內可以各種亂玩~

從自己的電腦連接云主機一般需要SSH這樣的東西。既然有如此機會，干脆系統性學習下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是一種加密的網絡協議，用于在非安全網絡下建立到網絡設備的安全鏈接。SSH被廣泛用于遠程計算機的命令執行，類似VPS，云主機等設備都需要SSH進行操作。

SSH連接

建立SSH連接有多種方式：

1. Linux/Unix 系統下Terminal直接創建
2. Linux/Unix/Windows 系統下使用三方軟件創建
3. 瀏覽器中創建，需要JRE，并且很多瀏覽器已經不支持
4. Chrome中使用插件創建

主要說說Chrome中插件的方案

Secure Shell：在Chrome中使用SSH

首先下載個插件：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中的認證問題: NaCl plugin exited with status code 255

EC2一般使用.pem的Private Key進行認證，但是在使用Secure Shell中經常會遇到個問題：

Host key verification failed.
NaCl plugin exited with status code 255.
(R)econnect, (C)hoose another connection, or E(x)it?

看很多討論說原因是：SSH需要個Public Key，但是我們只有一個Private Key

很多Solution說需要生成一個Publick Key之類的，但是實際上Public Key這兒并沒有任何要求，我們只需要將自己的.pem復制一份然后擴展名改成.pub即可

比如自己的Private Key是123.pem那么復制一份然后命名為123.pen.pub， 然后Import的時候都選中即可

這看起來是個偏方不過確實有用
