Can you verify the permissions on the ProgData\ssh and ProgData\ssh\logs folders per #2282 (comment)?

Starting with v9.4, the sshd service will check the folder permissions upon startup to ensure only SYSTEM and Administrator accounts have write access (or higher) to the folder; similar to the existing check upon install in contrib\win32\openssh\install-sshd.ps1.

PS C:\Windows\system32> icacls "C:\ProgramData\ssh"

already ran install-sshd.ps1

[MikeEunLim]

thsi may be important issue i saw :
debug1: get_passwd: lookup_sid() failed: 1332.

[tgauth]

What is SSHSTORAGE\root? The account should have RX permissions at most on the SSH folder

For the log folder, RRISD\sshadmins should not have W permissions, just RX

[MikeEunLim]

i added root local accoutn jsut to see f that fixes on log on service policy for service.exe I can remove that

[MikeEunLim]

For the log folder, RRISD\sshadmins should not have W permissions, just RX , removed but still an issue totally the new patch broke it , seeing if I can undue the patch and try again

used to work until new patch was installed

[tgauth]

Ok - so with v9.8.1.0, the server runs in debug mode but the service won't start?

yes... added debug log mode on config..... but anywho.... trying to see if patch can be reverted and try again

[tgauth]

It still sounds like an issue with the folder permissions. I would ensure only SYSTEM and the administrators group have full control over ProgData\ssh and ProgData\ssh\logs and that all other accounts only have read access.

[MikeEunLim]

they both have full control..... do you have specific command line?

I used
icacls "C:\ProgramData\ssh" /grant SYSTEM:F /grant Administrators:F
icacls "C:\ProgramData\ssh\logs" /grant SYSTEM:F /grant Administrators:F

still same issue

[tgauth]

And all other accounts only have read access?

[MikeEunLim]

some have write to upload.

[tgauth]

To upload to the ProgData\ssh folder? The accounts need to be limited to read access, at least to start the service.

[MikeEunLim]

sorry just for these following directory
Match User svc_ftp_cppm
ChrootDirectory D:\Network\cppm

Match User svc_ftp_fac
ChrootDirectory D:\Network\FAC

Match User SSH_User
ChrootDirectory D:\Vmware

[MikeEunLim]

removing the root fixed it, on ssh

[MikeEunLim]

i think the solution is reinstall done fixhost ps1 and change the full access for programapp/ssh and logs and remove what I added on net user add.....

Sorry, finally its WORKING now just needed to remove Users Read permission from Keys which got inherited! 😊
