sshd_config已修改,ssh还是无法远程问题解决
环境:vmware
下的debian10.2
/etc/sshd/sshd_config
配置文件已经完成修改开启允许root账号登录配置
ssh远程返回如下信息:
[Administrator.NIHAORZ-WORK-PC] ➤ ssh root@192.168.36.135
Connection reset by 192.168.36.135 port 22
通过vmware
进入虚拟机查看服务状态返回:

显示缺失ssh_host_rsa_key
、ssh_host_ecdsa_key
和ssh_host_ed25519_key
三个文件
执行如下三条命令创建密钥文件:
ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key
ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key
再依次执行服务重启和服务状态查看命令,确认服务启动正常则尝试再次ssh
远程
systemctl restart sshd
systemctl status sshd
