When connecting an NVR running Ubuntu 12.04 or older to a newer S-series you may have issues with it connecting and displaying the “Disconnected” message on the archiving page; even thou everything is correct and systems running Ubuntu 14.04 or newer DO NOT have this issue.
When you search the logs, you will see a message stating it failed to connect.
There is a combination of configuration defaults that prevent an Ubuntu 12.04 server (or older) establishing an SMB connection to an Ubuntu 18.04+ (S-Series) server.
Samba changed their “allow ntlm” default from yes to no in version 4.5.0 The version of Samba available for Ubuntu 16.04 is 4.3.11 (still allows ntlm, no connection issue), and Ubuntu 18.04 is 4.7.6 (does not allow ntlm by default, so can’t connect).
The workaround used at the customer is to re-allow ntlm on the S-Series by adding ntlm auth = yes to the /etc/samba/smb.conf on the S-Series server and restarting smbd service.
You will need to either be right on the S-series or SSH in to it.
Run the following command in terminal from the S-series
sudo nano /etc/samba/smb.conf
Add the following in to it right above domains….. ntlm auth = yes
Make sure you save it when finished.
Next, restart the SMB service…
From terminal type the following sudo /etc/init.d/samba restart
Now, go back in to the Exacq Client>Archiving and disable archiving and re-enable it and it should connect.
