Cannot access samba shares on OSMC from MacBook

Help and Support Raspberry Pi
1

Hello,

During latest OSMC update I had a smb related error. To fix it I purged and reinstalled smb from the App Store.
After this, the samba service seems to be working normally but I cannot connect to my samba shares on OSMC from my MacBook anymore.
I tried either as user osmc or guest but none is working.
I also tried to add some Mac OS specific options to smb.conf according to this info: Configure Samba to Work Better with Mac OS X - SambaWiki
but also this did not help.
Could you please help me to debug this issue? I have uploaded the logs.

Thank you
Marco

You need to share the logs for us to advise.

Hello again,

I tried reinstalling the latest OSMC (2023.1) and unfortunately I still have the same problem. I can connect from my MacBook to osmc via smb://osmc@10.0.0.114 (this is the fixed ip of my osmc) and I can see the shares. However, as soon as I try to open folders on one of the shares, the connection is broken.

In the log.smbd there are segmentation errors:

I would think this is a bug in this smb version. The samba version integrated in OSMC is very old (2017) and out of maintenance. Is it possible to upgrade smb?

That doesn’t sound right.

I’d suggest posting some logs so we can check which version of OSMC you are using.

Aware you posted logs before, but they showed errors.

So please try and replicate on a fresh install with a fresh Samba install instead of with the modifications you made.

Hello,

I uploaded the new logs from a fresh install of OSMC 2023.01-1 where I just installed SMB from App Store.

https://paste.osmc.tv/suzagucero

The version of Samba that I get is 1.2.2, update 2017-11-21. That is also what I was getting in the previous installation after I upgraded to 2023.01-1.

Are you referring to the smb-app? Which actually seems to be 1.2.7? Anyway the smb-app is just a wrapper to install the respective samba components which is samba 2:4.13.13 as you can see in your logs.

I am referring to the info in the App Store, please see the screenshot (sorry for the poor quality)

yes the samba version is definitely not from 2017, although is seems not maintained anymore? Samba Release Planning - SambaWiki

As I wrote what you see there is the version number of the smb-app which is just a wrapper to install the current version of the samba application.

The version currently installed on your device is 4.13.13

Ok, do you have any suggestion on how to fix my issue? Each time I try to browse the samba shares I get disconnected and I see segmentation faults in the log.smbd so I cannot access any samba share at all.

Are nasty issues to figure out. Is that problem only happen when you try to open files from external folders or also if you e.g. open something from within the /home/osmc/ folder?

Hello,

my samba shares are on two USB HDD. I do not use shares on the OSMC SSD so I cannot give a feedback if a samba share in the /home/osmc can be normally accessed and only the external drives can’t. I could try if you think that test helps.

If I browse those drives from the osmc interface or via ssh, everything is working fine. Only access from samba is not working.

Yesterday I also tried a fresh install of OSMC 2022 but again samba is not working, although the behavior seem to be slightly different - I get no connection at all.

I will also try to open the shares from a Win10 PC instead of Mac.

Anyway, everything was ok until the last OSMC update where I encountered a samba error, that is why my suspects are on the OSMC side.

Thanks
Marco

Yes suggest to test that.

Which filesystem are they using?

Have you done a check on the SD Card?

15

I have checked with a Win10 pc and I did not manage to reach the shares. Maybe I did something wrong? I activated the CIFS /smb 1.0 support and tried to connect to //10.0.0.114/ or smb://10.0.0.114 or smb://osmc@10.0.0.114 but never managed to reach any share.

The two HDDs that are connected to osmc and auto mounted have both NTFS partitions, except one VFAT in one of the two.

I am not sure how to check the SD card, I tried with sudo touch /forcefsck and did not get any error. Also, I have installed with two different SD cards and get similar results so I would not expect both to be faulty.

16

You don’t need SMB v1 enabled in Windows to connect to a share on a different device. Also your using the wrong slashs. To connect via explorer you would use \\10.0.0.114 and Windows will ask for credentials if they are needed. If you had previously connected to and saved credentials for a device using that IP address then you might have to go into Windows credentials manager and edit or delete that entry.

17

Ok, thanks for the hints. I tried also \\10.0.0.114 but still cannot connect. Windows says it cannot access the location (error code 0x80004005)

18

Some positive news: it seems that the shares are accessible from iOS without errors, I can browse them with the VLC iOS app.

However, why have the shares always been working with Mac OS and now don’t? I have read some comment about issues with network shares in Mac OS 13, so this might also be the case? However also from Windows I cannot get access.

Furthermore, what about the segmentation faults in the log.smbd?

Hello,

I have been testing also with another PC and also from there everything works fine.
Unfortunately the problem is in Mac OS 13 and there is no fix yet. :sob:
I think that this thread can be closed.

Thanks a lot for the support!
