I can't seem to get the dhcp-dns system to work on my debian linux box.
DNS works, DHCP works, they won't work together?
I get a denied update in the syslog as shown below from the machine that has checked out one of the dhcp addresses? I'm not sure why it would be trying to update the named server?
The correct files seem to be generated in /var/lib/dhcp-dns, but
the update does not apply to my /etc/bind/db.mydomain files.
** Any help or ideas would be very greatly appreciated.
**
Please email the list and to me directly(droman@romansys.com) as
I am not on the Debian email lists.
Thanks,
---Dean Roman.

Description: DHCP server for automatic IP address assignment
DHCP is a protocol like BOOTP (actually dhcpd includes much
of
the functionality of BOOTPD!). It assigns IP addresses to
clients
based on lease times. DHCP is used extensively by Microsoft
and more
recently also by Apple. It is probably essential in any multi-platform
environment.
.
Multiple Ethernet Interfaces are supported by this DHCP package.
You need
to run Linux 2.0.32 or later.
