Radicale
Radicale is a server designed to support the CalDav and CardDav protocols. It operates either as a standalone package using its own internal http server or can be integrated with an existing webserver.
Installation
Configuration
The easiest thing is to follow the instructions at the Radicale website.
The main configuration file is located at /etc/radicale/config
.
Many of the configuration options can be changed on the command-line:
$ radicale --help
If you run a mail server the radicale-imap-gitAUR or radicale-dovecot-authAUR IMAP authentication plugins may be useful. If you use radicale-dovecot-auth with UNIX sockets, create a radicale.service
drop-in file with the following contents:
[Service] RestrictAddressFamilies= RestrictAddressFamilies=~AF_PACKET AF_NETLINK
This allows the process to open AF_UNIX
sockets.
Integration
Radicale can be integrated with HTTP webservers like Apache HTTP Server via Reverse Proxy or the WSGI interface.
Client support
Since it uses the CalDav and CardDav protocols, it should support most clients. Currently, the officially supported list is this.
The following list may or may not be accurate:
- Thunderbird Lightning extension and Cardbook
- GNOME/Evolution, Contacts and Calendar
- KOrganizer korganizer
- InfCloud infcloudAUR, CalDavZAP, CardDavMATE
- syncEvolution syncevolutionAUR
- aCal, ContactSync, CalendarSync, CalDAV-Sync CardDAV-Sync and DAVx⁵ for Android
- Mac OSX Calendar/Contacts
- Apple iOS
- Note that iOS requires a SSL in order to sync CalDAV/CarDAV (as of iOS14 self-signed SSL is sufficient for Radicale to integrate as an account) [1], this can be created by following the instructions in OpenSSL#Generate a self-signed certificate with private key in a single command.
- Note also that key sizes must be greater than 2048 bits [2]
