DHCP and Printers

[David A. Evans]

this same issue from time to time with our HP's. 
        The other similar issue with older flashes on the HP-Jet Directs 
is they will not accept a zero any octet of the IP address.  They will do 
exactly the same thing if the DHCP server attempt to give it to them.

I am running DHCP 3.0.5 on fedora core 4.  I have about 30 network
printers ranging from HP JetDirect boxes to Lanier printers.  I have
setup the DHCP server to assign an IP address to the printer, but I am
running into a problem.  It seems that some of the printers never
acknowledge the IP sent to them from the DHCP server and then tries to
request the ip over and over again. 

Here is some of the dhcp server log for the MAC address of one of my
printers.
Dec 11 10:55:22 moya dhcpd: DHCPDISCOVER from 00:00:74:b2:53:64 via eth0
Dec 11 10:55:22 moya dhcpd: DHCPOFFER on 10.39.5.53 to 00:00:74:b2:53:64

Dec 11 10:55:35 moya dhcpd: DHCPOFFER on 10.39.5.53 to 00:00:74:b2:53:64
via eth0
Dec 11 11:01:23 moya dhcpd: DHCPDISCOVER from 00:00:74:b2:53:64 via eth0
Dec 11 11:01:23 moya dhcpd: DHCPOFFER on 10.39.5.53 to 00:00:74:b2:53:64
via eth0
Dec 11 11:01:25 moya dhcpd: DHCPDISCOVER from 00:00:74:b2:53:64 via eth0

The only way to get it to work is to enter the IP address onto the
printer which I want to avoid doing.


Here are some of the relevant sections from my dhcpd.conf file

                   allow members of "reserve";
            } 
                 }
}

} 
-------------------------------------------------------------------
As you can see I am defining a subnet 10.39.5.0-255.  It contains some
printers and a few desktop computers.  There is also a small pool of
reserve addresses I use for sepcial events.  I am assigning the address
10.39.5.53 to the printer, but the printer never seems to get it.
Anyone have any ideas what I am doing wrong ???


Thanks in advance for the help :)
