Error Message: 'Privilege separation user sshd does not exist' occurs when attempting to start the CYGWin SSH daemon on Windows 7 Home Edition. This error affects users who have installed CYGWin and are trying to use its SSH features. The issue is frustrating because it prevents users from accessing remote servers using SSH, which can hinder productivity and hinder the ability to collaborate with others.

This problem arises due to a limitation in Windows 7's local user management system, making it difficult for CYGWin to create a separate user account for SSH privilege separation. Fortunately, there is a workaround that allows users to bypass this limitation and enable the necessary user account.

🛑 Root Causes of the Error

  • The primary reason for this error is that Windows 7 Home Edition does not support creating a separate user account for SSH privilege separation. This is due to a limitation in Windows' local user management system, which makes it difficult for CYGWin to create a new user account specifically for SSH purposes.
  • An alternative cause of this error could be if the 'Users' group policy is not configured correctly or if there are issues with the local security settings on the system.

🔧 Proven Troubleshooting Steps

Enabling the Privilege Separation User Account

  1. Step 1: Step 1: Open the Local Users and Groups Manager. This can be done by searching for 'Local Users and Groups' in the Start menu, or by typing 'lusrmgr.msc' in the Run dialog box (Windows key + R).
  2. Step 2: Step 2: In the Local Users and Groups Manager, navigate to the 'Users' container and right-click on it. Select 'New user'.
  3. Step 3: Step 3: In the 'Create a new user' dialog box, enter a username for the privilege separation user account (e.g., 'sshd'). Make sure to select the option to 'Create a new user in Active Directory' and click 'Next'.
  4. Step 4: Step 4: Enter the desired password for the privilege separation user account and click 'Finish'. This will create the necessary user account for SSH privilege separation.

Using an Existing User Account (Alternative)

  1. Step 1: Step 1: Choose an existing user account on the system that has sufficient privileges to run the CYGWin SSH daemon. This could be a standard Windows user account or a domain administrator account.
  2. Step 2: Step 2: Open the CYGWin configuration file located at 'C:ootoot.cfg'. This file needs to be edited to specify the user account and password for the SSH connection.
  3. Step 3: Step 3: Add the following line to the end of the 'CYGWIN' section in the boot.cfg file: 'use_ssh yes' and 'ssh_deny_algorithms no'. Save the changes and restart the CYGWin service.

🎯 Final Words

By following these steps, users can resolve the 'Privilege separation user sshd does not exist' error and enable the necessary user account for SSH privilege separation. If an alternative solution is chosen, users will need to edit the CYGWin configuration file and restart the service. With these fixes in place, users should be able to access remote servers using SSH on Windows 7 Home Edition.
