Cygwin的一个很酷的功能就是能够 cd 进入同一网络上的远程Windows机器：
[0 user@machine ~]$ cd //remote-machine/c$
[0 user@machine //remote-machine/c$]$ ls
Program Files/
Program Files (x86)/
ProgramData/
Users/
Windows/
这使我能够非常快速地完成与我的工作相关的许多事情，而无需使用Windows远程桌面进行连接。
但是，有时候我会在家工作，而且我会进入我的工作机器。从那里，我希望能够 cd 以相同的方式对这些相同的机器，但我不能这样做：
[0 user@machine ~]$ cd //remote-machine/c$
-bash: cd: //remote-machine/c$: Permission denied
我怀疑它与Cygwin sshd在通过ssh连接时如何处理用户有关。但是，我知道这是可能的，因为我有一个能够做到这一点的同事。不幸的是，他不记得他在sshd设置中是否做了什么特别的事情。
这是我的输出 ssh-host-config 在我的设置期间（以管理员身份启动Cygwin mintty）。
