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...
配置SSH客户端,使用与华为交换机匹配的host key算法进行连接: 一旦你找到了支持的算法交集,你可以在SSH客户端的配置中指定使用这些算法。例如,在OpenSSH客户端中,你可以通过添加-oHostKeyAlgorithms=+<algorithm>选项来指定要使用的host key算法。 bash ssh -oHostKeyAlgorithms=+ssh-rsa user@switch_ip ...

Diffie-hellman-group-exchange密钥交换算法的最小长度小于等于2048bits时,为弱安全算法不建议使用。如需配置,需执行undo crypto weak-algorithm disable命令使能弱安全算法功能后才能使用。建议将最小长度设置为3072bits。 配置SSH服务器端的加密算法列表。 ssh server cipher{des_cbc|3des_cbc|aes128_cbc|aes256_cbc...
