我在 NAS 上设置了公钥和私钥，一切正常。但是，我无法禁用密码提示：PS C:\Users\Stefan> ssh[电子邮件保护]-p 9222 -o PubkeyAuthentication=否 [电子邮件保护]的密码：仍然要求输入密码。我的 sshd_config 文件如下：

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

PermitRootLogin without-password
因此，在我尝试 ssh 连接的服务器上，我的 PasswordAuthentication 设置为 no。有什么想法吗？谢谢

如果您在创建密钥时设置了密码，则在使用密钥时必须输入密码。您可能需要研究 Linux Expect 脚本来为您输入密码...
