Radicale
From dmfswiki
Radicale is a light-weighted open source CalDAV server written in python. It is easy to use and can even run without any configuration. It does not need a database like Mysql or Postgres as it stores all calendars as plain ics files in your file system.
Setup
CalDAV-Sync
Please use the latest GIT version of Radicale to sync with CalDAV-Sync. With this version setup is straight forward:
- Server: <your.server.name>:5232
- use SSL: leave ticked if you configured Radicale with SSL
- Username: your user name
- Password: your password
CardDAV-Sync
Radicale does not yet support CardDAV (as of July 12th 2011) but some work has been done and support is on the way.
