Nutzbare Daemons

  • pimd - multicast routing daemon (PIMv2)
  • smcroute - static multicast router daemon
  • mrouted

pimd HowTo

  • Stelle sicher, das der Kernel die folgenden Optionen aktiviert hat. Siehe /boot/config-$(uname -r)
CONFIG_IP_MULTICAST

# Respect user CFLAGS, remove upstream optimisation and -Werror
sed -i Makefile -e '/^CFLAGS/{s|[[:space:]]=| +=|g;s|-O2||g;s|-Werror||g}' || return 1
