dhcpd.conf

Hi!

I've configured my dhcpd.conf to use more than one DNS so that in case one is down the other takes over. But the problem is the ipconfig/all (for microsoft PCs) always shows the same DNS server. So when that server is down I've to reconfigure dhcpd.conf (comment the line for that offline server and let dhcpd.conf accept other servers)

i.e.
#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#

default-lease-time 36000;
max-lease-time 36000;
#domain name
option domain-name "mylinuxforme.co.zz";
#name server
option domain-name-servers 196.xx.xyz.10;
option domain-name-servers 196.xx.wxy.10;

By this, ipconfig/all always takes 196.xx.xyz.10, if that server is down I've to comment the line
#option domain-name-servers 196.xx.xyz.10;
and then dhcp server takes 196.xx.wxy.10 as dns

How can I reconfigure dhcpd.conf so that it takes all dns servers?

Thanks,
Stefano

in configs linux always takes the first entry of an option
in your case just simply add the alternate addresses into the first line separated by ","

Code:

option domain-name-servers 196.x.y.z, 196.y.z.a;
