Win*_*Win 12 authentication putty sshd ssh-keys
我有这个线程中描述的完全相同的问题，但是那里接受的答案对我来说不是正确的，因为用户的主目录是本地的。
我认为我在客户端（Windows 7、PuTTY 的 PAGEANT、PUTTYGEN 和 PLINK）正确配置了所有内容，但我似乎没有使公钥机制起作用（基于密码的 ssh 登录有效）。我遵循了以下所有步骤、提示和提示：
我现在怀疑我可能在服务器端（Linux、sshd）上遗漏了一些东西，所以我发布了当前/etc/ssh/sshd_config内容：
Protocol 2
SyslogFacility AUTHPRIV
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PasswordAuthentication no
PermitEmptyPasswords yes
ChallengeResponseAuthentication no
UsePAM yes
X11Forwarding yes
Subsystem sftp /usr/libexec/openssh/sftp-server
知道我做错了什么吗？

现在，我确实注意到了两条bad ownership or modes for directory /home/winwin消息，但我检查了目录 /home/winwin 和 AFAICT 的所有权或模式，它们没问题：
/home> ls -lad winwin
drwxrwxr-x 21 winwin winwin 4096 Jul 13 21:24 winwin
和：
/home/winwin> ls -lad .ssh
drwxr-xr-x 2 winwin winwin 4096 Jul 14 12:06 .ssh
和：
/home/winwin/.ssh> ls -lad *
-rw-r--r-- 1 winwin winwin 210 Jul 14 12:06 authorized_keys
-rw-r--r-- 1 winwin winwin 210 Jul 14 01:58 authorized_keys.pub
-rw-r--r-- 1 winwin winwin 394 Jul 14 01:57 authorized_keys.pub.orig
可能有什么问题？
更新二：我chmod 600按照以下答案中的建议进行了尝试：
/home/winwin> ls -lad .ssh
drw------- 2 winwin winwin 4096 Jul 14 13:13 .ssh
和：
/home/winwin/.ssh> ls -lad *
-rw------- 1 winwin winwin 210 Jul 14 12:06 authorized_keys
但它仍然不起作用。为什么我仍然收到Authentication refused: bad ownership or modes for directory /home/winwin错误？
尝试从您的主目录中获取组可写权限：
chmod g-w ~/
使您的 .ssh 文件夹只能由您读取/写入/执行：
chmod 700 ~/.ssh
使您的授权密钥文件只能由您读取/写入：
chmod 600 ~/.ssh/authorized_keys
那应该删除权限错误。
