Troubles accessing samba LAN shares on an ubuntu server

taproots · November 1, 2024 at 11:00 AM

Hello everyone!

I need some help on configuring kodi to access a samba share on a ubuntu machine. So far it always fails with an "Software caused connection abort" error message.

The server shows that kodi is connected:

Code

Samba version 4.19.5-Ubuntu
PID     Username     Group        Machine                                   Protocol Version  Encryption           Signing
----------------------------------------------------------------------------------------------------------------------------------------
10564   kodi         kodi         moviebox (ipv4:192.168.0.56:60142)        SMB3_11           -                    partial(AES-128-GMAC)

But "NT_STATUS_CONNECTION_DISCONNECTED" seems to be the reason the whole thing fails:

Da Flex please explain how our wiki article on adding content via the local LE samba server going to help diagnose an issue with the Kodi SMB client?

chewitt Sorry, I mixed up client and server.

On your Ubuntu Samba server, add/edit this at /etc/samba/smb.conf:

Code

client min protocol = SMB2
client max protocol = SMB3

Then restart the Samba server: sudo service smbd restart
