禁用键盘-交互式SSH登录
禁用键盘-交互式SSH登录
提问于 2021-08-25 04:46:40
我试图禁用键盘-交互式登录，因为我只想要键登录，但它不会禁用以下sshd_config。我还将编辑后的ssh -v登录附加到服务器上。
sshd_config：
MaxAuthTries 3
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PasswordAuthentication no
PermitEmptyPasswords no
ChallengeResponseAuthentication no
KbdInteractiveAuthentication no
UsePAM no
Subsystem sftp /usr/libexec/sftp-server编辑的ssh -v输出：

这是我的。它起作用了。只接受s/key。
