我正在尝试在 Raspberry Pi 上登录全新安装的 openSUSE Leap 42.2。该设置完全默认，并且 pi 上没有存储公钥。
当我尝试通过登录时出现错误：ssh [email protected]
Received disconnect from 192.168.1.56 port 22:2: Too many authentication failures
Connection to 192.168.1.56 closed by remote host.
Connection to 192.168.1.56 closed.
使用ssh -v表明正在提供大量公钥：
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/robert/.ssh/id_rsa
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Offering DSA public key: /home/robert/.ssh/id_dsa
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Offering RSA public key: robert@XXX
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Offering RSA public key: robert@yyy
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Offering RSA public key: robert@zzz
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Offering RSA public key: backup-login@xxx
我认为每次身份验证尝试都会计数并导致服务器停止与我通信。
果然，当我从不同的用户帐户登录时，出现密码提示。
在服务器上出现以下错误消息
Dec 09 20:27:18 linux sshd[1020]: error: maximum authentication attempts exceeded for root from 192.168.1.52 port 35088 ssh2 [preauth]
要解决此问题，请尝试强制进行密码身份验证，如下所述如何强制 ssh 客户端仅使用密码身份验证？：
ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no [email protected]
现在导致
Permission denied (publickey,keyboard-interactive).
在这种情况下如何才能使用基于密码的登录？
答案1
“密码”和“键盘交互”是两种不同的身份验证类型；楼主提供的是后者。因此，您需要在首选身份验证列表中使用它：
ssh -o PreferredAuthentications=keyboard-interactive …
