SFTP broken in LE12

dembala · July 12, 2024 at 7:28 AM

Hello!

Seems that FTPs connectivity (with TLS) is broken in LE12 as i found.

I've used LE 11.0.6 on 4 different devices (Raspberry 2-3-4-5) where i was able to connect to an FTP server with TLS authentication (FTPS). I upgraded / clean installed LE 12.0.0 where the same source gives me empty folder.

I have had this in sources.xml on both versions, i replaced username and password and server URL here:

Code

        <source>
            <name>FTPs</name>
            <path pathversion="1">ftp://username:password@servername:customport/folder/|auth=TLS&verifypeer=false</path>
            <allowsharing>true</allowsharing>
        </source>

Here is my log from LE 12.0.0 during attempt to enter in this source. Debug log was enabled in KODI. I've replaced my server details here again:

I've downgraded one of my machines from 12.0.0 and FTPs started to work as expected in 11.0.6. Then upgraded again to 12.0.0 and it stopped working. Definitely something wrong in 12.0.0

Here is the log from LE 11.0.6 which works fine. I replaced servername and port here again, notice that USERNAME AND PASSWORD are not in the log, those were replaced to these CAPITAL words by KODI, not by me.

ALSO PLEASE NOTICE, THAT THE /FOLDER AFTER THE SERVERNAME EXISTS HERE, WHILE IN ABOVE NON-WORKING SCENARIO ON 12.0.0 THE FOLDER IS MISSING AFTER THE SERVERNAME:PORT !! THIS WAS THE DIFFERENCE I COULD OBSERVE HERE IN THE LOGS.

Any clue what's going on in LE 12.0.0 ?

Thanks so much !

TLS provides encryption and not authentication. You are probably connecting to regular FTP service with StartTLS support and not to FTPS (or FTP-over-SSL)

dembala · July 12, 2024 at 11:56 AM

I haven't talked about SFTP, i was hoping to have been clear.

This is FTPS also known as FTP over TLS/SSL.

I'm not using any FTP service on LE, as i want to connect to one and not hosting one. In this sense, i'm FTP client.

All this above has worked in LE 9, 10, 11 from stock. Broken in LE 12.

Seems to be something in Kodi as the same is reported on Android https://github.com/xbmc/xbmc/issues/25118

**chewitt** · July 12, 2024 at 3:06 PM

Also possibly related https://github.com/xbmc/xbmc/issues/23785

dembala · July 13, 2024 at 7:55 AM

chewitt Thanks for these links. Very interesting indeed. I was expecting an OS component here that could have been the root cause, but seems its rather KODI related indeed. Not sure how Android and LE shares versions of certain linux components that could be the cause. Anyway, this is a NO GO for me to use LE12, as i'm relying on FTPS to access my NAS from different places. I'll just skip LE12 for now and use LE11. Hoping there will be an update eventually on KODI and/or LE12.

They don't share components, they share code. The NFS client is internal to Kodi.

Hi guys, I can confirm that the problem exists - tested on a self-built .ova image based on latest 21.1 kodi (commit 7938029863608416aaf85ee1dd2bb9cb84dc6d7b from LE repo).

I was able to fix the issue by upgrading the curl package to the latest version - 8.9.1 (previously was 8.6.0). Versions 8.7+ have some fixes related to FTP - https://curl.se/changes.html

If the issue is the same as the WebDAV issue, then the le12 nightly has the fix. https://github.com/LibreELEC/LibreELEC.tv/pull/9178

quev · August 19, 2024 at 4:38 PM

No, my first build had this patch already and it was not working.

**vpeter** · August 19, 2024 at 6:31 PM

It works on LibreELEC-Generic.x86_64-12.0-nightly-20230309-5426f16.img.gz.

You need to enable component logging in Kodi and select libcURL as component. This will show you much more information in log file to compare.

quev · August 19, 2024 at 9:49 PM

Curl was at 7.88.1 at that point (https://github.com/LibreELEC/Libr…l/package.mk#L6) which is the same major version as in LE 11 (7.86) so that does not tell us much.

I believe there must have been a regression going to version 8 which is fixed in 8.9.1 (maybe it also works on versions in between 8.6.0 and 8.9.1, have not tested but on 8.6.0 it does not work for sure and on 8.9.1 works ).

dembala · December 25, 2024 at 6:38 PM

Hi Guys,

What’s the conclusion here? Any fix in mainstream? 12.0.1?

Any plans for a fix? Do you know?

Cheers

**heitbaum** · December 27, 2024 at 4:28 AM

Nightly 12 has the fix (after 12.0.1) RE: SFTP broken in LE12

**mglae** · December 27, 2024 at 9:49 AM

heitbaum 20230309 is older than 12.0.1 of 2024-10-17

Oops - didn’t read that.

dembala please try current LE12 nightlies. As if the issue is the same as the WebDAV issue, then the le12 nightly has the fix. https://github.com/LibreELEC/LibreELEC.tv/pull/9178

These are at https://test.libreelec.tv/12.0/ (scroll to the end an use the latest 202412xx image.
