Troubleshooting
|
|
===============
|
|
|
|
If the client fails to start syncing it basically can have two
|
|
basic reasons: Either the server setup has a problem or the client
|
|
has a bug. When reporting bugs, it is crucial to find out what part
|
|
of the system causes the problem.
|
|
|
|
Here are a couple of useful steps to isolate the problem.
|
|
|
|
:A general ownCloud Server test:
|
|
A very first check is to verify that you can log on to ownClouds web
|
|
application. Assuming your ownCloud instance is installed at
|
|
``http://yourserver.com/owncloud``, type
|
|
``http://yourserver.com/owncloud/`` into your browsers address bar.
|
|
|
|
If you are not prompted to enter your user name and password, or if you
|
|
see a red warning box on the page, your server setup is not correct or needs
|
|
fixes. Please verify that your server installation is working correctly.
|
|
|
|
:All desktop clients fail to connect to ownCloud:
|
|
The ownCloud syncing use the built in WebDAV server of ownCloud.
|
|
Verify that you can log on to ownClouds WebDAV server. Assuming your ownCloud
|
|
instance is installed at ``http://yourserver.com/owncloud``, type
|
|
``http://yourserver.com/owncloud/remote.php/webdav`` into your browsers
|
|
address bar.
|
|
|
|
If you are prompted, but the authentication fails even though the credentials
|
|
your provided are correct, please ensure that your authentication backend
|
|
is configured properly.
|
|
|
|
:Use a WebDAV command line tool to test:
|
|
A more sophisticated test is to use a WebDAV command line client and log
|
|
into the ownCloud WebDAV server, such as a little app called cadaver, available
|
|
on Linux. It can be used to further verify that the WebDAV server is running
|
|
properly, for example by performing PROPFIND calls:
|
|
|
|
``propget .`` called within cadaver will return some properties of the current
|
|
directory and thus be a successful WebDAV connect.
|
|
|
|
Logfiles
|
|
========
|
|
|
|
Doing effective debugging requires to provide as much as relevant logfiles as
|
|
possible. The log output can help you with tracking down problem, and if you
|
|
report a bug, you're advised to include the output.
|
|
|
|
:Client Logfile:
|
|
Start the client with ``--logwindow``. That opens a window providing a view
|
|
on the current log. It provides a Save button to let you save the log to a
|
|
file.
|
|
|
|
You can also open a log window for an already running session, by simply
|
|
starting the client again with this parameter. Syntax:
|
|
|
|
* Windows: ``C:\Program Files (x86)\ownCloud\owncloud.exe --logwindow``
|
|
* Mac OS X: ``/Applications/owncloud.app/Contents/MacOS/owncloud --logwindow``
|
|
* Linux: ``owncloud --logwindow``
|
|
|
|
It is also possible to directly log into a file, which is an useful option
|
|
in case the problem only happens ocassionally. In that case it is better to
|
|
create a huge logfile than piping the whole log through the log window.
|
|
|
|
To create a log file, start the client with ``--logfile <filename>``.
|
|
|
|
:ownCloud server Logfile:
|
|
The ownCloud server maintains an ownCloud specific logfile as well. It can and
|
|
must be enabled through the ownCloud Administration page. There you can adjust
|
|
the loglevel. It is advisable to set it to a verbose level like ``Debug`` or ``Info``.
|
|
|
|
The logfile can be viewed either in the web interface or can be found in the
|
|
filesystem in the ownCloud server data dir.
|
|
|
|
:Webserver Logfiles:
|
|
Also, please take a look at your webservers error log file to check if there
|
|
are problems. For apache on linux, the error logs usually can be found at
|
|
``/var/log/apache2``. A file called ``error_log`` shows errors like PHP code
|
|
problems. A file called ``access_log`` usually records all requests handled
|
|
by the server. Especially the access_log is a very good debugging tool as the
|
|
log line contains a lot of information of every request and it's result.
|
|
|
|
More information about the apache logging can be found at
|
|
``http://httpd.apache.org/docs/current/logs.html``.
