hostkeyalgorithms 是SSH(Secure Shell)协议中的一个配置项,用于指定客户端在与服务器建立连接时,接受哪些主机密钥算法。主机密钥算法用于验证服务器的身份,确保客户端连接的是正确的服务器,而不是被中间人攻击的伪装服务器。 ssh-rsa 和ssh-dss 两种算法 ssh-rsa: ssh-rsa 代表基于 RSA 算法的 SSH 密钥对。RS...
ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa user@host -p 2222 上面比较麻烦,可以修改 ssh 配置文件 ~/.ssh/config,对于无法成功连接的 host,增加以下配置项: HostKeyAlgorithms +ssh-rsa PubkeyAcceptedKeyTypes +ssh-rsa 完整的配置如下: Host jump Port 2222 HostName x.x.x...
