[Sunhelp] Roadrunner and private network DNS

A long time ago, in a galaxy far, far way, someone said...

It depends on the dhcp client you use.  I use dhclient (from Internet
Software Consortium's dhcp server package) on my firewall.  The dhclient
config file (/etc/dhclient.conf) goes something like this:

supersede domain-name-servers 127.0.0.1;
supersede domain-name "domain1.com domain2.com";

interface "interface" {
        send host-name "hostname";
        script "/etc/dhclient.script";
}

syslog on Linux & FreeBSD can do that - it would surprise me if
SunOS/Solaris syslog can't.  Check the syslog.conf manpage.
