The best part is that my wife, Anna, assembled the whole system and installed Xubuntu Jaunty 9.04. She isn't very into this stuff, but she did it with very little direction and no physical help. What a sport!
sudo apt-get update
sudo apt-get install zoneminder
This doesn't get you 100% there--you have to enable ZoneMinder in Apache like so:
sudo ln -s /etc/zm/apache.conf /etc/apache2/sites-available/zoneminder
sudo a2ensite zoneminder
Now ZoneMinder was reachable at http://localhost/zm and I started configuration. I added the Panasonic camera as an external source (the same one from my last post), but the camera's page in ZoneMinder had no image. Going directly to the camera worked, so I knew I had a problem somewhere on my new system.
I enabled debugging in the "Options" section of the web interface and restarted Zoneminder:
sudo /etc/init.d/zoneminder restart
And found this in the debug logs located in /tmp:
07/04/09 09:21:11.757615 zmc_m2.DB1-zm_monitor.cpp/259 [monitor purpose=1]
07/04/09 09:21:11.757662 zmc_m2.DB1-zm_monitor.cpp/266 [shm.size=36865516]
07/04/09 09:21:11.757723 zmc_m2.ERR-zm_monitor.cpp/270 [Can't shmget, probably not enough shared memory space free: Invalid argument]
Google found me an answer in the ZoneMinder FAQ:
sudo sysctl kernel.shmmax=36869516
sudo sysctl kernel.shmall=46869516
To make this permanent, I created /etc/sysctl.d/60-shmem.conf and added:
# Needed for zoneminder camera buffer
kernel.shmall = 46869516
kernel.shmmax = 36869516
kernel.shmmni = 4096
My one camera is working great, but I'm anxiously awaiting 2 more that should arrive next week. I installed my BlueCherry video capture card and will post again when I've hooked up my other cameras.
