1.1 ! misho 1: Hello, ! 2: ! 3: For some specific application I needed to deny access to a MAC address ! 4: to a lease. For this reason I modified the dhcp-script behavior and is ! 5: called with an extra parameter "access" once a dhcp request or discover ! 6: is received. In that case if the exit code of the script is zero, ! 7: dnsmasq continues normally, and if non-zero the packet is ignored. ! 8: ! 9: This was not added as a security feature but as a mean to handle ! 10: differently some addresses. It is also quite intrusive since it requires ! 11: changes in several other subsystems. ! 12: ! 13: It attach the patch in case someone is interested. ! 14: ! 15: regards, ! 16: Nikos ! 17: ! 18: nmav@gennetsa.com ! 19: ! 20:
