SSH 错误 "failed to negotiate key exchange algorithm" 通常发生在SSH客户端和服务器无法就密钥交换算法达成一致时。以下是一些解决此问题的步骤: 确认SSH客户端和服务器版本兼容性: 确保SSH客户端和服务器软件都是最新版本,或者至少是彼此兼容的版本。旧版本的SSH客户端可能不支持新版本的SSH服务器所使用的某些算...

密钥交换(Key Exchange)是SSH中紧接着的第二步,它最直接的目的有两个:用一个安全的方式将接下来的packet加密密钥传到双方手中、让客户端相信“同时获得密钥的另一个人”就是千真万确的服务器。 第一步,客户端在payload中表明Message Code = 20(Key Exchange Init),并毫无保留的把自己支持的各种加密...
