大家好，今天我遇到了这个问题，cygwin 安装 CYGWIN SSHD的时候报出 3534的error。

?

然后查看/var/log/sshd.log

内容如下：

Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist
Privilege separation user sshd does not exist

解决方案：

?

在/etc/passwd中添加
sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin

在/etc/group中添加
/etc/group:sshd:*:22:

?
