problems with dhcpd.conf

pircio · 02-08-2006, 01:36 PM

I'm making a registration system, well actually made, but I lost dhcpd.conf in a terrible accident and have to rebuild, but here is my problem.

DHCPD.conf

Code:

server-identifier 10.0.0.1;
#ddns-update-style none;
#ddns-updates off;

subnet *.*.*.* netmask 255.255.252.0 {}
# ^ actual numbers there, that's my public ip declaration
 

shared-network "test" {
        subnet 172.16.0.0 netmask 255.255.254.0 {
                authoritative;        
                option routers 172.16.0.1;
                option subnet-mask 255.255.254.0;
                option broadcast-address 172.16.1.255;
                option domain-name-servers 172.16.0.1;
                max-lease-time 60;
                default-lease-time 120;
                range 172.16.0.2 172.16.1.254;
                allow unknown-clients;
        }
        subnet 10.0.0.0 netmask 255.255.248.0 {
                authoritative;
                option routers 10.0.0.1;
                option domain-name-servers 68.168.224.162;
                option subnet-mask 255.255.248.0;   
                option broadcast-address 10.0.7.255;
                max-lease-time 600;
                default-lease-time 7200;  
                range 10.0.0.2 10.0.7.254;
                deny unknown-clients;
        }
}
host rob {
        hardware ethernet 00:40:f4:72:02:49;
        fixed-address 10.0.0.27;
}
#host aj {
#        hardware ethernet 00:30:1b:30:7b:63;
#        fixed-address 10.0.0.2;
#}

Problems....

1) "host rob" gets 10.0.0.27 just like he should. "host aj" or any other system on the network gets a DHCP timeout, not a 172.16 IP.

2) If I uncomment #ddns-update-style none; or #ddns-updates off; I get the following errors:

/etc/dhcpd.conf line 4: expecting a parameter or declaration.
ddns-update-style
^
/etc/dhcpd.conf line 5: expecting a parameter or declaration.
ddns-updates
^

Just in case this is the culpret, here is my ifconfig info

Code:

eth1      Link encap:Ethernet  HWaddr 00:0C:41:E6:41:BD
          inet addr:10.0.0.1  Bcast:10.0.7.255  Mask:255.255.248.0

did you try apt-get install --reinstall dhcpd?

Never mind, I just realized you meant you lost all your tweaked settings...

why would I do that? dhcp works fine as a simple dhcp server. Is there something potentially broken with it? because "ddns-update-style none;" shouldn't be kicking back an error.

Figured it out

Code:

#dhcpd.conf

server-identifier 10.0.0.1;

subnet *.*.*.* netmask 255.255.252.0 {}

shared-network "test" {
        subnet 172.16.0.0 netmask 255.255.254.0 {
                authoritative;
                option routers 172.16.0.1;
                option subnet-mask 255.255.254.0;
                option broadcast-address 172.16.1.255;
                option domain-name-servers 172.16.0.1;
                max-lease-time 60;
                default-lease-time 120;
                range 172.16.0.2 172.16.1.254;
                allow unknown-clients;
        }
        subnet 10.0.0.0 netmask 255.255.248.0 {
                authoritative;
                option routers 10.0.0.1;
                option domain-name-servers 68.168.224.162;
                option subnet-mask 255.255.248.0;
                option broadcast-address 10.0.7.255;
                max-lease-time 600;
                default-lease-time 7200;
                range 10.0.0.2 10.0.7.254;
                deny unknown-clients;
        }
}
host aj { hardware ethernet 00:30:1b:30:7b:63; fixed-address 10.0.0.22; }
host rob { hardware ethernet 00:40:f4:72:02:49; fixed-address 10.0.0.27; }
host eggs { hardware ethernet 00:01:03:21:43:D6; fixed-address 10.0.0.4; }

actually it only seems to work when it wants to, i'm getting a tad upset.
