Configuration questions

Hi,
I've read just about all I can find and experimented like crazy for the
past three days. I think I'm ready to come ask now. Things seem to be
working, but I would appreciate some confirmation and some questions
answered.
I'm running bind-8.2.1, linux 2.2.12, at-one-time-Redhat 5.2, but
heavily updated.
I have two computers, a dialup ppp connection on one and and ethernet
between them. I am using the 192.168.75.0 network internally, the hosts
are assigned IPs of 10 and 11, 10 is the name server, has the modem. I
am using the domain "home", the computers are garath and garion, garath
is the nameserver.
I have written a script to switch me from online to offline which just
switches the "." zone file from the real one to any empty (and back) and
restarts named.
I have no registered domain name, so everything is bogus. (We need a
bogus-DNS-HOWTO :) Now for my questions.
1. Is it ok for this server to listen on the internet? I disabled that
by explicitly naming my eth and lo device address and not the ppp in a
listen-on option statement? Is this why I'm getting lot's of lame server
messages in my logs?
2. Looking through this newsgroup, I see some config files with "notify
yes" in their 192.168.x.x domains. I chose no; I don't think I should
be telling any other server about that domain. Which is correct?
3. This has me real confused: dig garath gives me this:
;; AUTHORITY SECTION:
. 1D IN SOA A.ROOT-SERVERS.NET.
hostmaster.internic.NET. (
1999090700 ; serial
30M ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
Shouldn't garath be the authority? Why is a root server involved in
this at all? Is that bad? I thought that I made garath the authority by
putting:
@ IN SOA garath.home. rwuest.wuest.org. (
In the zone config files. (it's the same in the fwd and reverse files).
Any comments would be appreciated.
The relevant config files:
resolv.conf:
search home
nameserver 127.0.0.1
named.conf:
options {
directory "/var/named";
forward first;
forwarders {
199.182.120.202;
199.182.120.201;
};
listen-on {
127.0.0.1;
192.168.75.10;
};
};
zone "." {
type hint;
file "named.ca";
};
zone "0.0.127.in-addr.arpa" {
type master;
file "named.local";
};
zone "75.168.192.in-addr.arpa" {
type master;
notify no;
file "home.rev";
};
zone "home" {
type master;
notify no;
file "home.fwd";
};
home.fwd:
@ IN SOA garath.home. rwuest.wuest.org. (
1999090502 ; serial
3600 ; refresh
900 ; retry
1209600 ; expire
43200 ; default_ttl
)
IN NS garath
; IN MX 10 garath
localhost IN A 127.1
garath IN A 192.168.75.10
garion IN A 192.168.75.11
home.rev:
@ IN SOA garath.home. rwuest.garath.home. (
1999090505 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ; Minimum
)
IN NS garath.home.
10 IN PTR garath.home.
11 IN PTR garion.home.
Thanks,
Robert
