linux – ssh仍然接受密码验证,尽管配置为仅公钥验证(有效！)

我已将Ubuntu 10.04LTS桌面安装配置为仅允许公钥验证.

结果：公钥认证工作完美！

问题：问题是,尽管配置为仅接受公钥认证,客户端仍然接受密码认证 – 为什么？

当然可以使用我看到的一些建议,并遵循这里的建议：ssh: can still use password after setting the key

遵循这些建议后没有成功：

> chmod 700 /home//.ssh
> chmod 600 /home//.ssh/authorized_keys
>添加到/ etc / ssh / ssh_config：

> PasswordAuthentication没有
> ChallengeResponseAuthentication no

> restarted sshd(命令：/usr/sbin / service ssh restart).

客户端的/ etc / ssh / ssh_config读取：

# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users,and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus,host-specific definitions should be at the beginning of the
# configuration file,and defaults at the end.

# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options,their meanings and defaults,please see the
# ssh_config(5) man page.

我错过了另一种选择吗？也许匹配(虽然这似乎不太可能对我有帮助)？

谢谢.

解决方法

/ etc / ssh / ssh_config用于客户端.您想在服务器配置文件中设置这些选项,即/ etc / ssh / sshd_config.
