Vallum files structure

Vallum is very friendly and does not modify any existing system file.
Vallum firewall is made of 3 main files:

• a filtering and logging network kernel extension loaded at boot time (/Library/Extensions/vallumnke.kext)
• a daemon running in background loaded at boot time (/usr/local/bin/vallumafd)
• an agent to handle user interaction, loaded at login time, runs as a menulet icon in OS X bar near the clock. (Vallum.app)

Vallum installs also its configuration file in /Users/Shared/it.murus.vallumlibrary.plist and stores custom presets in /Users/Shared/Vallum/. To activate Vallum at boot there is a launchd item in /Library/LaunchDaemons/it.murus.vallumafd.plist and shell script in /etc/vallum.sh.
