当安装完openssh-server后,服务正常启动，防火墙没有拦截，selinux关闭
sudo apt install openssh-server
sudo systemctl start sshd
sudo systemctl stop ufw
[ssl@ssl-PC /var/log]$ getenforce
Disabled
[ssl@ssl-PC /var/log]$ sudo iptables -L

当尝试连接时，直接拒绝，但是直接在机器上输入密码是没有问题的：
root@webserver:~# ssh root@192.168.1.12
The authenticity of host '192.168.1.12(192.168.1.12)' can't be established.
ECDSA key fingerprint is SHA256:30c8gNsdLcLt5DLLujcNpANWhSvFPLzmv5jS3a+BgnA.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
