I installed cygwin/sshd without good results. I removed the c:\cygwin directory to reinstall. I removed the sshd Administrator user by hand.

I reinstalled the cygwin again, then run the 'ssh-host-config -y', strangely, it doesn't ask anything about making a new user. And the procedure is really short.

$ ssh-host-config -y
* Query: Overwrite existing /etc/ssh_config file? (yes/no) yes
* Info: Creating default /etc/ssh_config file
* Query: Overwrite existing /etc/sshd_config file? (yes/no) yes
* Info: Creating default /etc/sshd_config file
* Info: Privilege separation is set to yes by default since OpenSSH 3.3.
 Info: However, this requires a non-privileged account called 'sshd'.
 Info: For more info on privilege separation read /usr/share/doc/openssh
ME.privsep.
 Query: Should privilege separation be used? (yes/no) yes
** Info: Updating /etc/sshd_config file

* Info: Host configuration finished. Have fun!

When I ran 'cygrunsrv -S shhd', I get an error. "Win 32 error 1069: The service did not start due to logon failure". It's reasonable message, as I deleted the sshd as a user, and the reinstall procedure did nothing for that again.

I see I got something wrong with the uninstallation.

Q: How can I uninstall the sshd related thing perfectly so that I can reinstall it again?

If sshd had been previously installed on the system, the following cleanup should be performed before invoking ssh-host-config:

# Remove sshd service
cygrunsrv --stop sshd
cygrunsrv --remove sshd
# Delete any sshd or related users (such as cyg_server) from /etc/passwd
#   (use your favorite editor)
# Delete any sshd or relaged users (such as cyg_server) from the system
net user sshd /delete
net user cyg_server /delete

I had to do three steps to make it reinstalled.

  • delete LOCAL_MACHINE\SYSTEM\ControlSet001\services\sshd
  • run 'sc delete sshd'
  • reboot

The problem is that I can't login the cygwin from the Mac, which is the exact reason I tried to reinstall the cygwin.

I made another thread about this problem. -> http://superuser.com/questions/110735/i-cant-login-cygwin-ssh-from-mac
