🍰 debian12换源、启动ssh连接

sudo apt update && sudo apt upgrade -y

sudo apt install openssh-server -y

sudo systemctl status ssh

正常应显示 "active (running)"

sudo nano /etc/ssh/sshd_config

PermitRootLogin yes # 如果允许root登录（或改为prohibit-password仅密钥登录）只要改这个就行了
PasswordAuthentication yes # 如果要用密码登录
PubkeyAuthentication yes # 如果要用密钥登录
AllowUsers yourusername root # 指定允许登录的用户（可选）
