Openssh升级到Openssh8.8最新版导致连接不上报错如下:
Nov 4 16:26:11 localhost sshd[16438]: Unable to negotiate with 192.100.0.112 port 50725: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]
原因是openssh8.8版本默认不再支持ssh-rsa算法
确认好sshd调用的配置文件后
echo ‘HostKeyAlgorithms +ssh-rsa,ssh-dss’ >>/etc/ssh/sshd_config 重启服务后解决
