Configuring Server-to-Server Sharing
========================================
ownCloud 7 introduces a powerful new feature, server-to-server sharing. With
just a few clicks you can easily and securely create public shares for sharing
files and directories with other ownCloud 7 servers. (Currently, this works only
with OC7 and not older versions.) You can automatically send an email
notification when you create the share, add password protection, allow users to
upload files, and set an expiration date.
Follow these steps to create a new public share:
1. Go to the Admin page and scroll to the Remote Shares section.
.. figure:: ../images/remote_shares.png
2. To enable server-to-server sharing, and to allow remote users to mount your
shares in their ownCloud 7 accounts, check ``Allow other instances to mount
public links shared from this server.`` Leaving the checkbox blank disables
server-to-server sharing.
3. You can enable the users on your local ownCloud server to mount
public link shares by checking ``Allow users to mount public link shares.``
When this is not checked your users cannot mount public link shares, though
they can view and download them.
4. Now go to your Files page and hover your cursor over the file or directory
you want to share to expose the administration options. Check the ``Share
Link`` checkbox to create the share, and to expose all of your sharing options.
.. figure:: ../images/create_public_share.png
Your new public share is labeled with a chain link. If you do not protect it
with a password, it is visible to anyone who has the URL. Users on other
ownCloud 7 servers can mount it and use it just like any ownCloud share.
Un-check the ``Share Link`` checkbox to disable the share.
See "Using Server-to-Server Sharing" in the Users Manual to learn how to
connect to a remote public share.
Notes
--------
Your Apache Web server must have ``mod_rewrite`` enabled, and you must have
``trusted_domains`` configured in ``config.php``. Consider also enabling SSL to
encrypt all traffic between your servers. (See "Manual Installation" in the
Administrators Manual to learn more about mod_rewrite, SSL, and alternative
HTTP servers. See "Installation Wizard" in the Administrators Manual to learn
more about configuring trusted domains.)
Your ownCloud server creates the share link from the URL that you used to log
into the server, so make sure that you log into your server using a URL that is
accessible to your users. For example, if you log in via its LAN IP address,
such as ``http://192.168.10.50``, then your share URL will be something like
``http://192.168.10.50/owncloud/public.php?service=files&t=
6b6fa9a714a32ef0af8a83dde358deec``, which is not accessible outside of your
LAN. This also applies to using the server name; for access outside of your LAN
you need to use a fully-qualified domain name such as
``http://myserver.example.com``, rather than ``http://myserver``.
