通过以太网使用SSH Root账户登录
重新安装系统后,默认禁用Debian Linux上的root进行登录。当您试图以root的身份登录到Debian Linux服务器时,您的访问将被拒绝。以下是示例信息:
$ ssh root@192.168.120.41 ssh: connect to host 192.168.120.41 port 22: Connection refused
若要启用SSH root身份登录,请执行以下步骤:
- 运行以下命令配置SSH服务器:
echo 'PermitRootLogin=yes' | sudo tee -a /etc/ssh/sshd_config
- 重启SSH服务器:
sudo systemctl restart sshd
结果:您可以用root用户身份使用SSH登录了。如输出以下结果,则表示登录成功:
示例输出
