[草稿]欧拉系统遇到的问题汇总

场景1：首次ssh报错 No compatible hostkey

问题：欧拉 openEuler-22.03 安装之后，通过 SecureCRT 配置 ssh 首次登录报错如下：

Key exchange failed.
No compatible hostkey. The server supports these methods: rsa-sha2-512,rsa-sha2-256,ssh-ed25519

解决：在别的机器远程ssh到这台欧拉机器

[root@4.51 ~]# ssh 172.30.3.196
Are you sure you want to continue connecting (yes/no)? yes
root@172.30.3.196's password:
