[Kodi 18 Leia] LibreELEC Testbuilds for RaspberryPi (Kodi 18.0)
Sad 
Running #1208 and changed root passwd via ssh and intially everything to connect remotely on network via shh with the modified root password was OK, but after power cut and reboot of rpi2 I am now unable to connect to root via ssh with "access denied" when attempting to connect? (I am sure I am using/typing new password correctly) Addtionally I have a crashlog, not sure if its relevant at all.

I'm sorry to have to tell you that this method of measuring the strength of a password is outdated.

Isn't it horsebatterystaple? Smile

The rules I listed are from the Linux manual, which is almost certainly outdated (it was intended only as a rough guide to illustrate a basic point), and IMHO passwords these days are pretty anachronistic - using public/private keys (and disabling passwords) is a much better/easier and more secure solution, and one we already support. I haven't used a password to login to OpenELEC/LibreELEC (or most of my other systems for that matter) for years, and only enabled the password in LibreELEC to test this feature (and I can testify it was tedious to enter, as I'm in and out of the system more frequently than most!)

The point is you now have the choice of setting whatever password you want, within reason (so long as it's not trivially simple/stupid). Debating password strength is something that should continue in it's own thread (please, so I can ignore it! Wink).

The crashlog seems to be CEC related.

As for the password. Hmm. Is the message you see "access denied" or "permission denied" - can you paste the exact message?

I'd expect the "permission denied" if you were entering an incorrect password. I'm not sure what would cause "access denied" - if sshd isn't running normally you'd see "connection refused".

In your crash log I can see you are having network issues, could that be your problem?

If all else fails and you want to reset the password then if you are able to mount the /storage partition in a Linux machine, you can delete the file /storage/.cache/shadow. Eventually we'll add an option to reset the root password in the LibreELEC Settings add-on (it's on the list of things to do), though obviously we'll need to think of a way of preventing it from being changed by those that shouldn't be changing it (ie. kids).

Make sure it's the shadow file in the .cache folder not the .config folder - you may have a shadow file in the latter still, as it was moved to .cache the other day.

I wonder if the file permission on the /storage folder has changed following the power loss which is now resulting in the "access denied" - it should be 755. I don't think this is a shadow password issue (but could be wrong).

At the end of the day this is a consumer system and we have to consider the interests of the average user - sadly they're not all as savvy as you! Smile

Also bear in mind that if the user enters a blank root password (which passwd would allow by default, for the root user) then the user will lock themselves out of the system because sshd by default does NOT allow a blank password, so the problem simply moves up the food chain - we'd need to alter the security profile of sshd for the handful of users that might want to enter a blank root password etc. Modifying passwd to prevent the root user from blowing their legs off really is the best option!

Besides, allowing weak/no passwords is something that an extreme minority might actually want, but don't forget we're debating a password that nobody has been able to change for the past 6+ years and not being able to use a blank or weak password is now an issue! Smile

Is there a reason why libbluray is not updated to 1.0.2?

Yes, because LibreELEC is using a patch from Nevcairiel on top of 1.0.1 which needs to be updated before we can bump to 1.0.2.

Sadly this kills pulseaudio, this fact itself is not sad, but it prevents us from using bluetooth headphones/speakers because pulseaudio devices don't get enumerated.
I don't use your builds but I do steal some nice patches like that one from LE git.
Quick-and-dirty poor man's hack - https://gist.github.com/asavah/788aacd89...0b6c45b61c , works as expected.
Maybe it helps while a proper patch is being worked on.

Thanks, that looks like it might only work on the RPi - I think we might need something more that works for all platforms.

Thanks but it's the permissions on the /storage folder as Linux sees it that I was after - you'd have to mount the SD card in a Linux PC, I think. Duff permissions (as sshd can be very picky about that sort of thing, quite rightly) is about the only thing I can think of right now that would prevent sshd from working. If you have Samba enabled you can access your logfiles in the Logfiles share - open the latest zip and inside you'll have dmesg and journalctl logfiles which might give a clue as to what is wrong (upload the zip to dropbox and post the link if you don't get anywhere).
