我曾经能够建立与Raspberry Pi的ssh连接,但突然对我失败。
通常的登录方式是
ssh [email protected]
并要求输入密码。
但是今天,当我下班回来时,突然拒绝了我的访问权限,甚至都不要求输入密码。可以肯定的是,由于Raspberry Pi存放在非常安全的位置,因此不会有人惹恼我,我的家人不会也不打算使用它。
笔记:
known_host
文件来重新开始并重新生成密钥,但无济于事。这是错误日志

能够获得一个监视器并访问该/etc/ssh/sshd_config
文件。
找到了罪魁祸首,
PasswordAuthentication no
更改为是,我可以再次连接。
