Windows-Fileserver: Windows Server 2012

When trying to enable external storage notify using sudo -u www-data occ files_external:notify 1 we get the error “Notify is not supported with the used smb version”.
We have php-smbclient, php-libsmbclient and smbclient binary installed.

In the smb.conf file we added client min protocol = SMB2and client max protocol = SMB3with no success.
After disabling php-smbclient so it uses the smbclient binary, none of the external storages work, with the error message “NT_STATUS_OBJECT_NAME_INVALID”.

Using smbclient, we can connect to the fileserver in the ubuntu console, but using “allinfo /” command returns the same error “NT_STATUS_OBJECT_NAME_INVALID”.

Is there any way to either:

Get external_storage:notify to work with the php-smbclient OR
Get the smbclient binary to work
Error when using smbclient binary:

    Error when using smbclient binary in console, issuing allinfo / command:
    “Server doesn’t support UNIX CIFS calls.”

[stefanoklett]

there is really no way to run this? This is a real problem.
There is any working version?

regards

[Jogoedota]

had to update ubuntu to 19.10 to install smbclient version 4.10.7 which worked.

[stefanoklett]

really?
This for the client side of SMB?
Many thanks

[Jogoedota]

Yes, had to add client min protocol = SMB2 and client max protocol = SMB3
aswell to the smb.conf and reboot the server for it to work.

[stefanoklett]

Interesting, I did the upgrade, and now:

sudo -u www-data php occ files_external:notify -u stekhome/stefano -p 1

smbXcli_negprot_smb1_done: No compatible protocol selected by server.
Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

In Exception.php line 17:

Unknown error (NT_STATUS_NOT_IMPLEMENTED) for Notify is not supported with the used smb version

of curse I set the client min/max protocol in smb.conf...
regards

[Jogoedota]

Whats your SMB-Servers configuaration? Seems like it doesn't support SMB2/3

[stefanoklett]

The SMB Server is a Synology (last version).
Of curse is configured with:

[global]
min protocol = SMB2
max protocol = SMB3

I'm frustraded, no ideas.

[Jogoedota]

You configured the client to only use SMB2/3, but your Synology seems to not support it or is not enabled. You should be able to enable it in Control Panel->File Services

[stefanoklett]

It is exactly what I did, over the Control Panel. I just check on the smb.conf file.
In any case, I can connect to the share thought nextcloud but I can't synchronize local changes

[stefanoklett]

To avoid the following messages I have to enabe SMB1(NT1) on the server:
smbXcli_negprot_smb1_done: No compatible protocol selected by server.
Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

Then site client:

[global]
min protocol = SMB2
max protocol = SMB3

But the error persist:

sudo -u www-data php occ files_external:notify -u stekhome/stefano -p mypassword 1

In Exception.php line 17:

Unknown error (NT_STATUS_NOT_IMPLEMENTED) for Notify is not supported with the used smb version

Any other ideas where to search?

[stefanoklett]

It seams that nobody is using Nextcloud with Synology.
Will me nice to know where to search.

I can see on Synology that after I run the command:
$ sudo -u www-data php /var/www/nextcloud/occ files_external:notify -u STEK.HOME/user -p password 1
The files will be download:

/home/.nc_test_folder/subfile.txt
/home/.nc_test_file.txt

But I still get the following error:

In Exception.php line 17:

  Unknown error (NT_STATUS_NOT_IMPLEMENTED) for Notify is not supported with the used smb version  


files_external:notify [-u|--user USER] [-p|--password PASSWORD] [--path PATH] [--output [OUTPUT]] [--] <mount_id>

Thanks for any help..

[Jogoedota]

You enabled SMB1 on the Synology but your smbclient wants to use SMB2/3, thats why its not working. You have to check if you can enable SMB2/3 on your Synology - if that doesn't work I guess you can't use notify.

[stefanoklett]

No, no.
If I setup SMB2/3 on boths:
smbXcli_negprot_smb1_done: No compatible protocol selected by server.

Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

In Exception.php line 17:

Unknown error (NT_STATUS_NOT_IMPLEMENTED) for Notify is not supported with the used smb version

When I setup NT1 to SM3 on Synology and SMB2/SMB3 on ubuntu client:

In Exception.php line 17:

  Unknown error (NT_STATUS_NOT_IMPLEMENTED) for Notify is not supported with the used smb version  

[stefanoklett]

To understand if is the Synology that answer with NT1, bot I think is not the case, because if I enable NT1 only (for test), I can't access the share from Win10 and Nextcloud/Ubuntu.
The impression that the occ request from Nextcloud/Ubuntu is using the bad protocol.
But the Nextcloud Share is accessible thought my Nextcloud portal.
There is any other confing file where to search.
I'm really frustrated with that, next steep is to use an other cloud system! I invested to much time on this.

[stefanoklett]

There is really no solution?
Then Nextcloud is for me unusable.

[Mpic]

I have the exact same problem, also with Synology external storage. With smbclient default version on Ubuntu 18.04 (4.7.6 I think), I could access the SMB shares with NextCloud but not enable notify.

I updated smbclient to 4.10.15 through the samba ppa, now NextCloud cannot even access SMB shares (giving this error screen) and trying to enable notify gives the same error as @stefanoklett :

sudo -u www-data /var/www/html/occ files_external:notify 1
smbXcli_negprot_smb1_done: No compatible protocol selected by server.
Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

I even tried uninstalling php-smbclient to be sure NextCloud uses smbclient binary.
By the way, accessing the shares directly with smbclient works, using either SMB2 or SMB3 :

smbclient //server/share -U user -m SMB2
smb: \> notify test_folder
0001 notification
...

I'm a bit clueless : some people reported that updating smbclient was enough to get notify working.

[txapelgorri]

Same problem here with this scenario:

• Ubuntu 20.04.1 with stable (official) packaging (no external PPAs, no snaps and the like).
• Nextcloud 18.0.10
• External storage 1.9.0
• Samba 4.11.6 running on same machine (no external hardware).

Samba is running with these 2 directives:

client min protocol = SMB2
client max protocol = SMB3

If I comment those two (Samba 4.11 does not need anymore to deprecate SMB1 explicitly as shown in https://wiki.samba.org/index.php/Samba_4.11_Features_added/changed#SMB1_is_disabled_by_default) the message:

smbXcli_negprot_smb1_done: No compatible protocol selected by server.
Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

is still there, and the occ command never ends.

The SMB shown during the occ command execution seems to be 3 though:

[Blobster21]

I have exactely the same issue using :
Ubuntu 20.04.1
Nextcloud 19.0.4
External storage 1.10.0
Samba 4.11.6 running on both the local and the distant machine

[global] client max protocol = SMB3 client min protocol = SMB2

While the rest of the occ scan command performs normally for local files, the samba shares scan always end up with the following message:

Starting scan for user 1 out of 1 (user1) smbXcli_negprot_smb1_done: No compatible protocol selected by server. Protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE
Both computers run the same min/max SMB3_11 protocol, to no available.

[alexander7567]

Same issue for me as well :( Running Ubuntu 20.04 with Nextcloud 20.0.2. I also get the error when I try to run php cron.php
