ssh-host-config 不起作用，我在创建 sshd 作为服务时收到此错误。我正在运行安装了 cygwin 的 Windows 7 32 位。
在安装 cygwin 后，它一开始是可以工作的。我执行了几次 ssh-host-config。我想确保更改 ssh 和 sshd 的配置，所以我卸载了。不记得是否有错误。我用这些卸载和重新安装时的说明。
我按照说明进行操作这站点，怀疑更改这些目录的权限会搞乱我的系统。在某个地方，不记得在哪里，我看到了一条关于所有权的错误/警告消息，它会搞乱一切。也许这是一个很好的教程，我不知道。
错误如下：
/usr/bin/cygrunsrv: Error installing a service: CreateService: Win32 error 1057
这是 ssh-host-config：

我尝试重新安装 openssh 和 cygrunsrv，但没有帮助，仍然出现错误。
如何删除 ssh、sshd 和 cygrunsrv 的所有配置文件？如何让 ssh 安装 sshd 作为服务？有什么想法吗？谢谢 Kristjan

我按照答案中的说明进行操作这线。
摘抄：
For Windows XP.
To remove Cygwin sshd in the cleanest possible way:
Disclaimer
cygrunsrv -E sshd
cygrunsrv -R sshd
delete the folder c:\cygwin and all its sub-folders
remove the Environment Variable CYGWIN
edit the Environment path accordingly
Start...Run... regedit and delete these two registry trees
"HKEY_CURRENT_USER_Software_Cygnus Solutions"
"HKEY_LOCAL_MACHINE_Software_Cygnus Solutions"
Go to Control Panel, Category View, Performance and Maintenance, Administrative Tools, Computer Management.
or click Start...Run...compmgmt.msc
delete the sshd user if it exists in the "System Tools" - "Local Users and Groups" - "Users" section.
EDIT: These steps were originally for XP, and you may need to re-install cygwin afterwards.
清理re-install了cygwin
现在它已经可以正常工作了。
