After my Zoneminder computer was attacked by a hacker i am more concerned about security. I has installed fail2ban and a firewall but those are things not easy to set for a newbie.
Could i run linux and zoneminder from a customerised CD and record events, database, etc on harddisk?
This way, with a simple reboot everything would go back to original stage.
Boot from cd write to disk
What you describe is possible by using the bootcode "changes= " in the commandline at boot. For example adding "changes=/dev/hda1" will layer a writable filesystem over the CDs readonly layer and write any new or updated files in a directory named "changes" on /dev/hda1. At reboot if the same "changes= " switch is used changes from the previous run will be retained and new changes will continue to be saved. If the changes directory is deleted everything will be set back to original.
Please consider that this is not a simple "silver bullet" for internet serurity. If your system is attacked the database and saved events are vulnerable. Whatever security hole the attacker exploited will still be present at reboot. Security requires effort. There are tools in the Mandriva Control Center to harden your system. Security updates should be applied. Passwords changed from the defaults, etc. We all need to be responsible about these things because if our systems are compromised they can then be used to attack others.
