1) The option domain-name-servers should be defined in the subnet block
2) Unless you are running DNS on your default gateway machine, I believe that you need to have a different DNS server.


My dhcpd.conf looks like this:

subnet 192.168.0.0 netmask 255.255.255.0 {
 option routers 192.168.0.1;
 max-lease-time 604800;
 default-lease-time 604800;
 range 192.168.0.20 192.168.0.30;
 option domain-name-servers xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx;
}

Where the xxx.xxx.xxx.xxx are replaced with the correct DNS addresses.

HTH..



Yes...you are right if you know your DNS, but if your gateway has DNS assigned by ISP?? I solved installing Bind, is it correct?

Here is the top portion of my dhcpd.conf:

###

default-lease-time 8640000;       # one day
max-lease-time 8640000;           # one day


ddns-update-style none ;


server-identifier dmc.uucp; option domain-name "uucp"; option domain-name-servers 192.168.24.10; #option domain-name-servers 24.3.196.33, 24.3.196.34; option routers 192.168.24.254;


# You can have no range but still need subnet information # on the IF you have dhcpd running on


subnet 192.168.24.0 netmask 255.255.255.0 { range 192.168.24.31 192.168.24.224; # option subnet-mask 255.255.255.0; option broadcast-address 192.168.24.255; option routers 192.168.24.254;


option time-offset -18000; # Eastern Standard Time


# This didn't work at all ## If you have Samba acting as a WINS server ## # option netbios-name-servers 192.168.24.10; # option netbios-dd-server 192.168.24.10; # option netbios-node-type 8; # option netbios-scope "ISO"; }


host d { hardware ethernet 00:20:AF:F2:EB:FE; fixed-address 192.168.24.21; option domain-name "uucp" ; option smtp-server 192.168.24.10 ; }

On my network I have my own dns (tinydns/dnscache). The above works
for use with various Windows boxen (needed for school). Note the
commented out 24.x.x.x network. That was the DNS for the old @home
service.
