Yet another SMBv2 issue

Hi there,

So I did read:

* RE: SMB shares not working - LibreELEC 8.95.001 on Raspberry PI 2

But I still fail to configure kodi after switching my freebox this monday to SMBv2. I can still access my SMBv2 share from my main linux workstation (cifs mount share), so the switch was rather smooth. But for some reason I am missing something on RPi3b+ side.

Here is what I have in /storage/.kodi/userdata/sources.xml (everything is pure ASCII):

Code

<source>
<name>musicvideo</name>
<path pathversion="1">smb://guest:guest@FREEBOX_SERVER/Freebox/musicvideo/</path>
<allowsharing>true</allowsharing>
</source>

I picked 'guest' / 'guest' since I do not use account/password in my configuration:

After reboot and selection, here is what I get in the /storage/.kodi/temp/kodi.log:

Code

2021-04-27 20:46:46.012 T:1936857536   DEBUG: OpenDir: Using authentication url smb://USERNAME:PASSWORD@FREEBOX_SERVER/Freebox/musicvideo
2021-04-27 20:46:47.033 T:1936857536   ERROR: SMBDirectory->GetDirectory: Unable to open directory : 'smb://USERNAME:PASSWORD@FREEBOX_SERVER/Freebox/musicvideo'
unix_err:'16' error : 'Invalid argument'

If I use 'guest' / 'guest' from my main linux workstation this works as expected:

Code

$ smbget -u guest -w RMT -R -v 'smb://RMT;guest@FREEBOX_SERVER/freebox/Photos'
mkdir failed on directory /var/run/samba/msg.lock: Permission denied
Can't open directory guest: Unknown error 8216
Password for [guest] connecting to //freebox/FREEBOX_SERVER:
Using workgroup RMT, user guest
smb://RMT;guest@FREEBOX_SERVER/freebox/Photos/bla.jpg

Here is what i have on my linux x86 workstation (and it is working fine)

Code

//freebox_server/freebox on /media/freebox type cifs (rw,relatime,vers=3.0,sec=none,cache=strict,uid=1000,forceuid,gid=1000,forcegid,addr=192.168.0.254,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,nobrl,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1,x-systemd.automount,_netdev)

My goal is to avoid going back to the old SMBv1 protocol so that my work laptop (windows 10) can access my freebox share drive.

I have also tried setting min and max SMB protocol in the Kodi UI (currently SMBv2 as min and max).

What should I try next ?

Thanks

Users frequently try to avoid setting a credential on shares believing "no passwords" to be easier. It is not, and how different OS with different versions of SMB/CIFS software will work gets a bit random. Set a credential and then configure the things that need to access the share to use it. This is how the software has been designed to work. This is how you get a consistent experience over all devices.

The “guest” user is special in windows. I would suggest a different username.

SMB Guest Login

Thanks for the support. So I did setup a simple freebox/freebox credential, reboot the freebox (mini 4k) and updated on the kodi side with:

Code

<source>
<name>musicvideo</name>
<path pathversion="1">smb://freebox:freebox@FREEBOX_SERVER/Freebox/musicvideo/</path>
<allowsharing>true</allowsharing>
</source>

I rebooted the kodi system (LE 9.2.6). And looking at the kodi.log file I still see the same message:

Code

2021-04-30 19:01:26.462 T:1454392192   DEBUG: OpenDir: Using authentication url smb://USERNAME:PASSWORD@FREEBOX_SERVER/Freebox/musicvideo

2021-04-30 19:01:27.485 T:1454392192   ERROR: GetDirectory - Error getting smb://USERNAME:PASSWORD@FREEBOX_SERVER/Freebox/musicvideo/

I did check from my amd64 linux workstation that the setup was accepting account correctly:

Code

smbget -u freebox -w RMT -R -v 'smb://RMT;freebox@FREEBOX_SERVER/freebox/Photos'
mkdir failed on directory /var/run/samba/msg.lock: Permission denied
Can't open directory freebox: Unknown error 8216
Password for [freebox] connecting to //freebox/FREEBOX_SERVER:
Using workgroup RMT, user freebox
bla.jpg is up-to-date, skipping

If I enter the wrong password I get an error:

Code

% smbget -u freebox -w RMT -R -v 'smb://RMT;freebox@FREEBOX_SERVER/freebox/Photos'
mkdir failed on directory /var/run/samba/msg.lock: Permission denied
Can't open directory freebox: Unknown error 8216
Password for [freebox] connecting to //freebox/FREEBOX_SERVER:
Using workgroup RMT, user freebox
Can't open directory smb://RMT;freebox@FREEBOX_SERVER/freebox/Photos: Permission denied

Is there a way to have even more verbose message, or a tool to diagnose the issue ?
