WND Configuration Quick Guide
|If you are using Ubuntu 20.04 as your OS, you will need to add this repository:|
sudo add-apt-repository ppa:ondrej/php
First, you need to install the samba packages and libraries that are required for the Windows Network Drives app.
sudo apt-get update sudo apt-get install -y smbclient php-smbclient coreutils libsmbclient
Next, you have to enable the Windows Network Drives app, either in the Web Interface or the command line:
The Windows Network Drive app has to be downloaded from in the Market App. Navigate to the Market app, search for Windows Network Drives and install it.
sudo -u www-data php occ market:install windows_network_drive
Enable external shares:
Navigate to admin → settings → storage (in the admin section)
Enable the external storage
Create a new share and choose Windows network Drives
Configure external share:
Folder Name: A name for the WND Share
Authentication: Choose Log-in credentials, save in database
Host: domain name or IP address
Share: name of the top share
Remote Subfolder: enter
$userfor every user to get a home drive
Permission Manager: leave empty to use the default one
Domain: domain name of your server
Available for: limit access to groups
Settings: (gear wheel) enable the options you need
|If you plan to use ownCloud only in the Web Browser - your setup of the WND is complete.|
If you plan to use a desktop client, you need to continue and configure the WND listener and WND process queue.
Lastly, you need to setup the wnd listener and process queue to propagate the changes made directly on the storage of your share to the sync client.
This can be done in 2 ways:
you configure a new systemd service for the listener and setup a process queue cron job
you setup a cronjob for the wnd:listen command and process queue cron job
Create a service for systemd following the instructions below that checks the share for changes:
For each WND mount point distinguished by a SERVER - SHARE pair:
Place one copy of a file with following content under
Replace the all upper case words
PASSWORDin both, the filename and in the contents below with their respective values.
Take care to also adjust the paths in
ExecStartaccording to your installation.
Password: Create a file readable only by the www-data and outside the directories handled by apache (let’s suppose in /tmp/mypass). The file must contain only the password for the share. In this example our file is: "/tmp/mypass". The listener will read the contents of the file and use them as the password for the account. This way, only root and the apache user should have access to the password.
"--password-trim" removes blank characters from the password file added by 3rdparty software or other services.

Run the following command, once for each created file:
sudo systemctl enable owncloud-wnd-listen-SERVER-SHARE.service sudo systemctl start owncloud-wnd-listen-SERVER-SHARE.service
Create or add a
crontab file in
crontabentry to run a script iterating over all
SERVER SHAREpairs with an appropriate
occ wnd:process-queuecommand. The commands must be strictly sequential. This can be done by using
flock -nand tuning the
* * * * * sudo -u www-data /usr/bin/php /var/www/owncloud/occ wnd:process-queue <HOST> <SHARE>
Parallel runs of
wnd:process-queue might lead to a user lockout. The reason for this, is that several
wnd:process-queue might use the same wrong password because it hasn’t been updated by the time they
It’s recommended to force the execution serialization of the
wnd:process-queue command. You might want to
use Anacron, which seems to have an option for this scenario, or wrap the command with flock.
If you need to serialize the execution of the wnd:process-queue, check the following example with flock
* * * * * flock -n /tmp/wnd001 occ wnd:process-queue server1 share1 * * * * * flock -n /tmp/wnd002 occ wnd:process-queue server1 share2 * * * * * flock -n /tmp/wnd003 occ wnd:process-queue server2 share3
The process queue will not work if there is a backslash in the share path configured in webui.
The process queue will not work if the share name in the webui is configured starting with a forward slash
If you encounter issues using Windows network drive, then try the following troubleshooting steps:
Check the connection to the share by using smbclient on the command line of the ownCloud server. Here is an example:
smbclient -U Username -L //Servername
Take the example of attempting to connect to the share named MyData using occ wnd:listen. Running the following command would work:
sudo -u www-data php occ wnd:listen MyHost MyData svc_owncloud password
The command is case-sensitive, and it must match the information from the mount point configuration.
When the output of the
occ process-queue ..command shows
0 Storages found, then this means, that there was no corresponding external storage configuration found, because:
The casing between calling the process queue and the web interface does not exactly match.
The authentication method is not correctly configured, it needs to be Log-in credentials, save in database
