DaviCAL installation

Fed up with waiting for Snow Leopard I decided to set up a calender server on our Linux server. After some searching I found out that Davical would be the best solution, especially since we use thunderbird and would like to use lightning as a calerdar client.

I installed DaviCAL on our Ubuntu 7.10 server, this was not very easy! All in all I can't even rember how I exactly did it. My plan is do to the same on a second server and document this step by step.

Most important thing for me is that is all works! There are some disadvantages, but none to big.

Some things to watch out for:

• In the permissions file of PostgreSQL (pg_hba.conf), make sure to post the access control rule at the top of the configuration document!
• The username in the caldav access URL is casesensitive!
• Use this as URL: http:////caldav.php//home/

Since DaviCAL uses PostgreSQL instead of MySQL a extra backup routine is important for me. Our MySQL database is backup, so I added an extra backup script:

# PostgresSQL Backup:
mv /network/backups/Database_Backup/Daily6_PostgreSQL_DaviCAL.sql /network/backups/Database_Backup/Daily7_PostgreSQL_DaviCAL.sql
mv /network/backups/Database_Backup/Daily5_PostgreSQL_DaviCAL.sql /network/backups/Database_Backup/Daily6_PostgreSQL_DaviCAL.sql

Adding an Axiz PTZ camera to ZoneMinder

ZoneMinder has the ability to control a PTZ (Pan, Tilt, Zoom) through it's user interface.

I added a Axis 213 PTZ dome camera to our ZoneMinder server using the following settings (After turning on PTZ in the Options->System tab (ZM_OPT_CONTROL), and restarting ZoneMinder):

General Tab:

• Source type: remote
• FPS: 6.00 (keep this high or you will get a delay in the image)
  

Soure Tab:

• Remote host name: xxx.xxx.xxx.xxx
• Remote host port: 80
• Remote host path: /axis-cgi/mjpg/video.cgi?resolution=CIF
• 24 bit colour
• Capture width: 384
• Capture Height: 288

Control Tab:

• Control Type: Axis API v2
• Control Device:
• Control Address: xxx.xxx.xxx.xxx:80 (mind the ':' and the port number !!)

And now for the tricky part, at least on my system (Ubuntu 8.04) you need to install a special Perl module:

• sudo apt-get install libmodule-load-perl

Took me about an hour to figure that one out!
