OK,
Let's get to the bottom of this. With a properly functioning dns and
dhcpd the system should be be idiot proof and work 100% of the time. It's
that simple. For LM, BIND and dhcpd work flawlessly once configured. Your
dhcpd.conf should look something like this: (of course there are more
options and your internal LAN address may vary)
subnet 192.168.7.0 netmask 255.255.255.0 {
# default gateway
option routers 192.168.7.13; (** this is your Linksys Router
address***)
option subnet-mask 255.255.255.0;
option domain-name "**whatever your domain is**.com";
option domain-name-servers 192.168.7.14; (this is your server
running B IND)
option netbios-name-servers 192.168.7.14; (ditto)
ddns-domainname "**whatever your domain is**.com";
range dynamic-bootp 192.168.7.20 192.168.7.100; **whatever works for
you**
default-lease-time 21600; (up to you)
max-lease-time 43200; (ditto)
# Adding zone information
zone "**whatever your domain is**.com". {primary 127.0.0.1; }
**** note the "." after the domain name in the line above -- syntax -- very
important!****
}
Now if your running BIND, your named.conf should look something like this:
// Filename: /etc/named.conf
options {
directory "/var/named";
forward first;
forwarders { 205.218.118.1; 208.180.0.2;}; *** whatever yours are
****
};
zone "." {
type hint;
file "named.ca";
};
zone "localhost" {
type master;
file "localhost";
};
zone "0.0.127.in-addr.arpa" {
type master;
file "127.0.0";
};
zone "**whatever your domain is**.com" {
type master;
file "**whatever your domain is**.com (your zone filename that
is)";
allow-update{**whatever your domain is**.com;}; (**not the most
secure, but bind 8 wouldn't generate a secure key**)
};
zone "7.168.192.in-addr.arpa" {
type master;
file "192.168.7";
allow-update{localhost;}; (**same comment as above**)
};
Your various zone files in /var/named will automatically update and should
look like this:
[root@Nemesis david]# ls /var/named
127.0.0* 192.168.7 localhost* named.ca* named.local* rbpllc.com (that's
my domain)

** In a nutshell, that's it! There is NO free ride, read the documentation
and get it set up. Once it is set up, it is bulletproof and fast as a
"scaulded ape" And ------ if there are any questions, politely as Andrew, he
is the guru that helped me get through the fog. Andrew Bartlett (E-mail
Address(es): [EMAIL PROTECTED]) Just don't tell him I gave you his
address!
Sorry Andrew, I didn't know anyone else that would be albe to pick it up
from here. Andrew, just FYI, weather is just fine in Texas, hope it's OK
down under as well! If it makes you feel an better, my daughter is named
Sydney.........
