Files¶

The files module supports:

Assistant¶

The Group-Office Assistant is a small program that you can install on your Windows, MacOS or Linux computer. It will automatically download files opened from Group-Office and monitor it for changes. When the file is saved it automatically uploads it back to Group-Office.

It also assists in mounting a network drive.

Download it for:

Collabora Online¶

With Collabora Online you can edit office documents in your browser. You need a working Collabora Online server. More info on https://www.collaboraoffice.com/code/

Configuration¶

For Collabora to work you need to setup SSL and allow your Group-Office URL to use it.

SSL¶

We’ve used the Debian packages and setup SSL with Letsencrypt. Then we’ve added this SSL configuration to /etc/loolwsd/loolwsd.xml:

<ssl desc="SSL settings">
    <enable type="bool" desc="Controls whether SSL encryption is enable (do not disable for production deployment). If default is false, must first be compiled with SSL support to enable." default="true">true</enable>
    <termination desc="Connection via proxy where loolwsd acts as working via https, but actually uses http." type="bool" default="true">false</termination>
    <cert_file_path desc="Path to the cert file" relative="false">/etc/letsencrypt/live/groupoffice.co/cert.pem</cert_file_path>
    <key_file_path desc="Path to the key file" relative="false">/etc/letsencrypt/live/groupoffice.co/privkey.pem</key_file_path>
    <ca_file_path desc="Path to the ca file" relative="false">/etc/letsencrypt/live/groupoffice.co/fullchain.pem</ca_file_path>
    <cipher_list desc="List of OpenSSL ciphers to accept" default="ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH"></cipher_list>
    <hpkp desc="Enable HTTP Public key pinning" enable="false" report_only="false">
        <max_age desc="HPKP's max-age directive - time in seconds browser should remember the pins" enable="true">1000</max_age>
        <report_uri desc="HPKP's report-uri directive - pin validation failure are reported at this URL" enable="false"></report_uri>
        <pins desc="Base64 encoded SPKI fingerprints of keys to be pinned">
        <pin></pin>
        </pins>
    </hpkp>
</ssl>

Network¶

Change network settings to allow posting from your Group-Office URL. We’ve used intermesh.group-office.com for example:

<net desc="Network settings">
   <proto type="string" default="all" desc="Protocol to use IPv4, IPv6 or all for both">all</proto>
   <listen type="string" default="any" desc="Listen address that loolwsd binds to. Can be 'any' or 'loopback'.">any</listen>
   <service_root type="path" default="" desc="Prefix all the pages, websockets, etc. with this path."></service_root>
   <post_allow desc="Allow/deny client IP address for POST(REST)." allow="true">
     <host desc="The IPv4 private 192.168 block as plain IPv4 dotted decimal addresses.">192\.168\.[0-9]{1,3}\.[0-9]{1,3}</host>
     <host desc="Ditto, but as IPv4-mapped IPv6 addresses">::ffff:192\.168\.[0-9]{1,3}\.[0-9]{1,3}</host>
     <host desc="The IPv4 loopback (localhost) address.">127\.0\.0\.1</host>
     <host desc="Ditto, but as IPv4-mapped IPv6 address">::ffff:127\.0\.0\.1</host>
         <host desc="The IPv6 loopback (localhost) address.">::1</host>
         <host desc="intermesh" allow="true">intermesh.group-office.com</host>
         <host desc="office" allow="true">office.group-office.com</host>
   </post_allow>
   <frame_ancestors desc="Specify who is allowed to embed the LO Online iframe (loolwsd and WOPI host are always allowed). Separate multiple hosts by space."></frame_ancestors>
 </net>

Storage¶

Change the backend storage to allow your Group-Office URL:

<storage desc="Backend storage">
    <filesystem allow="false" />
        <wopi desc="Allow/deny wopi storage. Mutually exclusive with webdav." allow="true">
        <host desc="intermesh" allow="true">intermesh.group-office.com</host>
        <host desc="office" allow="true">office.group-office.com</host>

            <host desc="Regex pattern of hostname to allow or deny." allow="true">localhost</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="true">10\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="true">172\.1[6789]\.[0-9]{1,3}\.[0-9]{1,3}</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="true">172\.2[0-9]\.[0-9]{1,3}\.[0-9]{1,3}</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="true">172\.3[01]\.[0-9]{1,3}\.[0-9]{1,3}</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="true">192\.168\.[0-9]{1,3}\.[0-9]{1,3}</host>
        <host desc="Regex pattern of hostname to allow or deny." allow="false">192\.168\.1\.1</host>
        <max_file_size desc="Maximum document size in bytes to load. 0 for unlimited." type="uint">0</max_file_size>
    </wopi>
    <webdav desc="Allow/deny webdav storage. Mutually exclusive with wopi." allow="false">
        <host desc="Hostname to allow" allow="false">localhost</host>
    </webdav>
</storage>

After making these changes restart loolwsd:

sudo systemctl restart loolwsd

Check the status:

sudo systemctl status loolwsd

If anything is wrong view the logs:

sudo journalctl -u loolwsd

Group-Office¶

When Collabora is running you can setup Group-Office to use it. Install the Office Online module from the Business package.

Reload Group-Office and go to System Settings -> Office Online

Then add your Collabora Code Service. The default port for Collabora is 9980.

Now every user can go to the files module and use it. Just right click a file and choose “Open with…”.
