dhcpreg -- DHCP registration utilities
http://www.systhug.com/dhcpreg/
Dhcpreg is a suite of utilities to be used for maintaining "registered"
DHCP sites. This can be useful for sites that require pay before using
or at least where all CPE devices have to be registered, such as cable
modem or dsl rollouts.
Requires Interrupt.pm which is available in source or RPM form from
Systhug: http://www.systhug.com/Interrupt/
Secure version requires the dhcpd.conf and dhcpd.leases file to be
readable by group 'wheel' and for the dhcpd.conf to be writeable by group
'wheel'. This is more suitable for using dhcpreg with CGIs.
The standard version installs itself suid to minimize group
affiliations. This is only recommended for secured, limited access
servers.
