Privilege separation is set to yes by default since OpenSSH 3.3.
However, this requires a non-privileged account called 'sshd'.
For more info on privilege separation read /usr/share/doc/openssh/README.privsep.
Should privilege separation be used? (yes/no) yes
Warning: The following function requires administrator privileges!
Should this script create a local user 'sshd' on this machine? (yes/no) yes
Generating /etc/sshd_config file
Added ssh to C:\WINDOWS\system32\drivers\etc\services
Warning: The following functions require administrator privileges!
Do you want to install sshd as service?
(Say "no" if it's already installed as service) (yes/no) yes
Which value should the environment variable CYGWIN have when
sshd starts? It's recommended to set at least "ntsec" to be
able to change user context without password.
Default is "ntsec". CYGWIN=ntsec
The service has been installed under LocalSystem account.
To start the service, call `net start sshd' or `cygrunsrv -S sshd'.
Host configuration finished. Have fun!
Add domain users:
$ mkgroup -d
$ mkpasswd -d
