Soon I'm going to a lanparty and I had some problems already. My own DNS-server couldn't resolve the name, so no website for me. Fortunally my ISP's DNS-server could resolve the address. At first I attempted to change some DNS-settings, so I could point my own DNS-server to a "master dns server". In the end, I edited the template of /etc/dhcpd.conf , thus giving all local clients an second dns-server, the dns-server of my ISP.

I've changed: copied the file 25DomainNameServers from /etc/e-smith/templates/etc/dhcpd.conf to /etc/e-smith/templates-custom/etc/dhcpd.conf and changed the contents:

   option domain-name-servers { $LocalIP . "," } ;

after this /sbin/e-smith/expand-template /etc/dhcpd.conf and service dhcpd restart and presto!. (Of course, you should pick an DNS-server that's close to you).
