SSH简介 SSH是Secure Shell(安全外壳)的简称,是一种在不安全的网络环境中,通过加密机制和认证机制,实现安全的远程访问以及文件传输等业务的网络安全协议. SSH协议采用了典型的客户端/服务器模式,并基于TCP协议协商建立用于保护数据传输的会话通道.SSH协议有两个版本,SSH1.x和SSH2.0(本文简称SSH1和SSH2),两者互不兼容.SSH2在性能和安全性方面比SSH1有所提高. SSH工作过程 阶段 说明 连接建立 SSH服务器在22号端口侦听客户端的连接请求,在客户端向

昨天在自己的远程服务器上玩,把系统重装了.新装了MySQL,在本地用navicat连接的时候出了几个小问题. 问题一:SSH: expected key exchange group packet from server 这个问题在网上查了查说是navicat自己的问题,升级版本就好了.没管那么多,在SSH选项卡里把使用ssh通道取消了,使用常规连接. 问题二:2003 - Can't connect to MySQL server on 'XXX' (10038) 第一个问题刚解决,但是第二个

背景:SecureCRT 的SSH正常使用过程中,突然出现: Key exchange failed. No compatible hostkey.The server supports these methods: RSA,rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ssh-ed25519 解决步骤: 1.先是重启服务器的sshd:service sshd restart 2.删除secureCRT的SSH2.ini文件 3.重启secureCR
