Cygwin - create SSHD service on Windows

1) Download Cygwinx64 installer 2) Run the installer, and add the packages:

Net->OpenSSH
Admin->Cygrunsrv

All other prerequisites will be selected automatically. 3) Run Cygwin terminal as administrator 4) Run the command

ssh-host-config -y

5) Create a unique windows user for uploads with Server Manager 6) To let Cygwin 'see' the new user, run:

mkpasswd --local > /etc/passwd
mkgroup --local > /etc/group

7) Create /home/newuser/.ssh folder, and upload / generate keys for the new user. Don't forget authorized_keys from the repository.  8) Login as the new user, and run the following:

chmod 700 .ssh
chmod 600 .shh/authorized_keys
 

9) Edit /etc/sshd_config (I usually use the following settings):

Port 22
AuthorizedKeysFile .ssh/authorized_keys
PasswordAuthentication no
PermitEmptyPasswords no
UsePrivilegeSeparation sandbox 

10) Restart sshd via mmc -> Services
