This page will explain how to install Apple's iCal Server on Ubuntu Server, though desktop variants should also work without any problems.
What is CalDAV? Explain that here, together with an explanation between CalDAV and WebDAV/webcal, with a link to a page describing how to make that happen.
Installing Apple's iCal Server is fairly trivial once you know what to do. We do need to download some additional packages using apt-get, and we need to download some software using subversion. Most users will be familiar with apt-get, many with subversion. If you're not familiar with subversion, don't panic. This guide will be a detailed, step by step howto, showing exactly which commands to enter and when. BR BR Ready? BR * Log into the server console or via ssh, so you can enter commands, and run sudo -s to get a root shell. BR * Install subversion: apt-get install subversion BR * Execute the following commands. It's ok to simply copy and paste them. It's quite alot of packages, and it may take a while for all of them to download and install. BR
apt-get install libkrb5-dev BR apt-get install attr BR apt-get install subversion BR apt-get install curl BR apt-get install build-essential BR apt-get install libssl-dev BR apt-get install python-pysqlite2 BR apt-get install bzip2 BR apt-get install curl BR apt-get install zope3 BR apt-get install python-xml BR apt-get install python-pyopenssl BR apt-get install python-dateutil BR apt-get install python-xattr BR apt-get install python-pysqlite2 BR apt-get install python-twisted BR apt-get install python-vobject BR apt-get install python-kerberos BR
* We now need to edit our /etc/fstab file and add user_xattr to the options for the partition containing the CalDAV server, / in this case: vim /etc/fstab. BR BR This is how my change looked like: BR Before: UUID=94a96528-c889-45a1-bc98-d9d02ecdd59c / ext3 defaults,errors=remount-ro 0 1 BR After : UUID=94a96528-c889-45a1-bc98-d9d02ecdd59c / ext3 defaults,errors=remount-ro,user_xattr 0 1 BR BR BR * We must now remount the filesystem: mount -o remount / BR * We'll install the server in /opt, so lets change into it: cd /opt BR * Let's download the server software itself using subversion: BR svn checkout http://svn.macosforge.org/repository/calendarserver/CalendarServer/trunk CalendarServer BR * Subversion has downloaded alot of software, and created a directory for us, called CalendarServer. Let's change into it: cd CalendarServer BR * And run a script to download some necessary packages, configure, etc: ./run -s BR * Ok, our CalDAV server is almost ready for action. Let's copy the test configuration so we can get it up as quickly as possible. Real configuration can wait: BR cp conf/caldavd-test.plist conf/caldavd-dev.plist BR * We do need to do some configuration though: vim conf/caldavd-test.plist BR BR
ADD PRECISE DESCRIPTION OF NECESSARY EDIT FOR EXTERNAL CONNECTIONS AND FOR EVOLUTION USERS!
* Run the server: ./run * That's it!
