[Owncloud] CalDAV / CardDAV with IPhone 5

[Christian Pfarr]

on my ubuntu server, my firewall block port 8008. Switching the Port
to 80 dont help. 
How do you explain that the demo server of owncloud on
http://demo.owncloud.org/ [1] doesnt work? 
On this Server, my Iphone
automatically change the Port to 8008. Why? 

And also a very
interesting question: Why its impossible to connect via SSL to
http://demo.owncloud.org/ [1]?

works, but the port is automatically switched to 8008. This Port is
locked on my own Server because of my firewall. Why does Iphone 5 using
this Port?

8008 first by default, since that is what OS X server uses. If your
ubuntu server has port 8008 open for something else (e.g. some web based
control panel or something?) … your iphone finds port 8008 open and
thinks it is contacting an OS X server. It then gets a garbage response
and fails. My server is not listening on port 8008 at all, so it tries
80 and succeeds.

if you are running ubuntu, then it should not be listening on port 8008
unless it has specifically been configured to listen on that port.
