SSH 服务器拒绝我们的密钥:无效用户

SSH 服务器拒绝我们的密钥:无效用户

我想通过公钥/私钥登录 SSH。

  • 我使用 sshd_config 中提供的端口添加了两个用户。两者都有文件夹 .ssh(chmod 700)和文件 authorized_keys(chmod 600)。

  • 用户 A 可以使用其密钥进行连接

  • 用户测试不能使用他们自己的或用户的密钥登录。(我将两个公钥都添加到authorized_keys中,
    并且密钥粘贴正确)

错误:

Server refused our key
No supported authentication methods available server sent: publickey

我不知道该怎么办。下面,您可以找到 sshd_config 和 /var/log/auth_log

sshd_配置:

# 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

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.
