SSH fails with Firmware 2.31.193

[Jimmologist]

My “My Cloud PR4100” updated to firmware 2.31.193 and now I can no longer SSH to it.

I’m very familiar with the process and have been doing it quite a bit but as soon as 2.31.193 installed, SSH always fails on the login. It connects, prompts for password but rejects the valid password.

Things I’ve tried:

1. Reboot the PR4100
2. Turn SSH off and back on again
3. Reset the SSH password
4. SSH from Windows 10
5. SSH from Mac OS
6. putty from Windows 10

And nothing can login. Again, I can connect, and get prompted for the password but regardless what I enter, the password is rejected.

My “My Cloud PR4100” updated to firmware 2.31.193 and now I can no longer SSH to it.

See the dedicated subforum for the PR Series where people more familiar with that device may be able to assist and where there may be past discussions on similar issues.

For example there is a discussion from a few weeks ago on an SSH problem with the 2.31.193 firmware on the PR Series.

PR4100 Firmware update to 2.31.193 SSH issue

After the firmware update I can no longer access the device thru SSH like I have been for the last year and a half. I have turned off SSH and rebooted, then turned it back on and set a new password, nothing works. When trying to log in with root and the password (changed it 3 times now to see if it doesn’t like certain passwords), Putty and WinSCP both do the same thing, access denied.

If possible try rolling back the firmware to the previous firmware version where SSH worked and see if it fixes the problem.

Thanks! The solution was in the PR Series group and they said to use the sshd alias instead of root and that worked fine.
