我在此线程中描述了同样的问题,但是接受的答案不适合我,因为用户的主目录是本地的。
我认为我已经在客户端(Windows 7,PuTTY的PAGEANT,PUTTYGEN和PLINK)上正确配置了所有内容,但是我似乎没有使公钥机制起作用(基于密码的ssh登录起作用)。我遵循了以下所有步骤,线索和提示:
现在,我怀疑我可能在服务器端(Linux,sshd)上缺少了某些/etc/ssh/sshd_config
内容,因此我正在发布当前内容:
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
知道我在做什么错吗?

现在,我确实注意到了两条bad ownership or modes for directory /home/winwin
消息,但是我检查了目录/ home / winwin和AFAICT的所有权或模式,它们都可以:
/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
可能是什么问题?
更新二:我尝试chmod 600
按照以下答案中的建议进行操作:
/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
但这仍然行不通。为什么我仍然收到Authentication refused: bad ownership or modes for directory /home/winwin
错误消息?
~/.ssh
和~/.ssh/authorized_keys
。仍然没有运气。至于从主目录本身获取组的可写权限,我不能这样做,因为这会破坏创建该用户/组的全部目的。该用户的主目录必须是该组可写的(具有相同的确切名称和gid!)。+1寻求帮助。
