Live CD

The Live CD based on Knoppix which is based on Debian.

Structure

The Live CD contain multipurpose GNU/Linux software and a special software for elphel cameras. The software is organized as debian packages. Our debian packages are presented on our SourcreForge page in the Live-CD and Players sections.

Root file system of Knoppix is compressed and cloop kernel module is needed to decompress it on-fly when it is necessary. The CD contains comressed root file system, boot loader and flash tarballs for different modeles of our cameras.

If you already have installed Debian or Knoppix system, you can add some our debs to work with our cameras.

We recommend to install following packages from our SourceForge page:
• elphel-pack It has utilites to configure network specially for cameras (for rtp stream receiving), search cameras in the LAN, update flash and helper for Mozilla/Firefox to work with .sdp files.
• netcardconfig-knoppix elphel clone to configure network card and to make a simple bridge from several cards.
• patched MPlayer to watch and to record rtp stream from our cameras.

To install selected package(s) you may use the following command:

# dpkg -i --force-overwrite <deb-file-name>

Special software

netcardconfig

netcardconfig is an improved version of knoppix network configurator. It need root priveleges. It has two modes: interactive and batch.

...

It is called from startup script on our Live CD. If you have installed netcardconfig-knoppix not on our distro, it is possible you need to insert call to the script in a system startup script.

netcamconfig

Run "netcamconfig" as user "root" to apply additional network settings and some kernel parameters.

This script adds aliases for the network card with most popular LAN ip adresses, adds route records for multicast ip addresses and changes kernel parameters to prevent long i/o operations with hard drive,

It is called from startup script on our Live CD after netcardconfig. If you have installed elphel-pack not on our distro, possible you need to insert call for the script in a system startup script.
