Network Administrator: 2011

Building a new Ubuntu 10.04 LTS server. The old Ubuntu server needed a replacement of both hardware and software.

Hardware Setup:
A new 19" C2D DFI-ACP machine is used with four SATA drives:
- 250 GB System
- 500 GB Network Share
- 500 GB Backups
- 1 TB Zoneminder Events

Installation:
Ubuntu was installed from a CD without LVM on /dev/sda (250GB) Options chose where:
- Web Server
- File Server
- MySQL
- PostGreSQL

First network settings:
auto eth0
iface eth0 inet static
address 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.3

sudo ifdown -a
sudo ifup -a

The rest is mainly taken from this guide on www.zoneminder.com
http://www.zoneminder.com/wiki/index.php/Ubuntu_Server_11.04_64-bit_with_ZoneMinder_1.25.0_Preview,_FFmpeg,_libjpeg-turbo,_Webmin,_Cambozola

Update system software
sudo apt-get update
sudo apt-get upgrade

Set Zoneminder Shared Memory
sudo nano /etc/sysctl.conf

#Add in the following lines at the bottom of the file followed by an empty line:
kernel.shmall = 167772160
kernel.shmmax = 167772160

sudo reboot

sudo su

chmod 755 /etc/init.d/zm

Edit Zoneminder Script
#Because Ubuntu clears /tmp for some kind of reason at reboot,
#the /tmp/zm directory will also be deleted after a reboot. Creation in script/zmdc.in.pl
#will resolve this.

nano /usr/local/bin/zmdc.pl

#Add following lines (marked with a '+'-sign between the lines given (do not include '+').

foreach my $arg ( @ARGV )
        }
}

+# Create the directory first if it doesn't exist
+mkdir(ZM_PATH_SOCKS);
+

socket( CLIENT, PF_UNIX, SOCK_STREAM, 0 ) or Fatal( "Can't open socket: $!" );

my $saddr = sockaddr_un( SOCK_FILE );

#To be sure, add rights to the /tmp/zm directory

chown www-data:www-data -R /tmp/zm

Setup additional hard drives
mkfs.ext4 for all drives

/dev/sda1 as /
/dev/sdb1 as /var/www/zm/event/
/dev/sdc1 as /network
/dev/sdd1 as /backups

For the ZoneMinder share I set the noatime attribute to reduce write cycles.

sudo chown www-data:www-data events/

Setup PCI capture card
I used a Kodicom 4400R and an Ad-Link RTV24 card, with the following settings the machine booted in 18 seconds!
sudo nano /etc/modprobe.d/bttv.conf
alias char-major-81 bttv
options i2c-algo-bit bit_test=1
options bttv gbuffers=16 card=133,132,133,133,134,134,134,134 tuner=4,4,4,4,4,4,4,4

sudo adduser www-data video

Edit Apache:
change /var/www to /var/www/zm in /etc/apache2/sites-available/default

Well, that's the first part. The machine is now basically running. I can configure the rest of the ZoneMinder setup and I can see video now. Next up is transferring the data to this new machine, setup Samba, MySQL, backups and Apache.
