SSH service will not start on fresh Cygwin 1.7.15 install
- by Coder6841
OS: Windows 7 x64
Cygwin: 1.7.15-1
OpenSSH: 6.0p1-1
I'm attempting to install an SSH server on Windows 7. The tutorial that I'm following to do this is here: http://www.howtogeek.com/howto/41560/how-to-get-ssh-command-line-access-to-windows-7-using-cygwin/
The issue is that upon executing the net start sshd command I get the following output:The CYGWIN sshd service is starting.
The CYGWIN sshd service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
Here is the full output of the setup:

$ net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
Note that on the line *** Query: Enter the value of CYGWIN for the daemon: [] I haven't entered anything. Tutorials often say to use ntsec or ntsec tty here but those options are removed from the latest version of OpenSSH. I've tried using them anyway and the result is the same.
The file /var/log/sshd.log is empty. If I try just running the command /usr/sbin/sshd I get the output /var/empty must be owned by root and not group or world-writable.. The /var/empty directory has the following permissions: drwxr-xr-x+ 1 cyg_server root 0 May 29 15:28 empty. Google searches on this error did not turn up any working fixes. One person seems to have solved it by using the command chown SYSTEM /var/empty but that did not fix it in my case.
