解決 SSH連線時發生can't agree a host key algorithm錯誤 工具/原料 Putty 方法/步骤 1 下載Putty 2 Putty選用Telnet遠端連線,輸入IP與PORT並點選下方OPEN按鈕 3 輸入帳號=>ENTER=>接著輸入密碼=>ENTER,成功進入後會出現# 4 輸入並按下ENTER=>chmod 0600 /etc/ssh/ssh_host_rsa_key 5 輸入並按下EN...
server_host_key_algorithms 为了避免中间人攻击,客户端和服务端进行密钥交换的最后一步,需要使用服务端的Host Key对密钥交换过程中对的临时公钥进行签名。所以server host key algorithm就是定义了一系列服务端支持密钥签名算法,比如说ssh-ed25519,OpenSSH支持的算法列表见下图: encryption_algorithms 对称加密算法,在协商...
