Glad to hear you got NFS working.

Very basic, multiple ways to do this... in this everything is static
controlled by the dhcp server, one big mac address to name lookup table.
Some sort of dynamic dhcp-dns update might be better, but is out of scope=

for this email.
Good Luck,

Disclaimer:
I use settings like these on three different networks but this example
is not verbatim from any of them so there might be some errors...
Step one: Need DHCP server working on some machine
/etc/dhcpd.conf
=3D=3D=3D=3D
# dhcpd.conf
option domain-name "chaos";
option domain-name-servers 10.10.16.1;
option subnet-mask 255.255.255.0;
default-lease-time 3600;
max-lease-time 72000;
subnet 10.10.16.0 netmask 255.255.255.0 {
range 10.10.16.16 10.10.16.254;
option broadcast-address 10.10.16.255;
option routers 10.10.16.1;
}
host mordor {
hardware ethernet 08:00:07:26:c0:a5;
fixed-address mordor.chaos;
}
# repeat one of the host blocks for each static machine on your net,
# fix the ethernet address as required.
=3D=3D=3D=3D
Step two: DNS server working on some machine=20
(referred to by "domain-name-servers" above)
/etc/bind/db.chaos=20
=3D=3D=3D=3D
; BIND data file for local chaos network
$TTL 86400
@ IN SOA chaos. root.chaos. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
86400 ) ; Negative Cache TTL
;
@ IN NS chaos.
localhost IN A 127.0.0.1
moria IN A 10.10.16.1 =20
gondor IN A 10.10.16.2 =20
rohan IN A 10.10.16.3 =20
mordor IN A 10.10.16.4 =20
lorien IN A 10.10.16.5 =20
shire IN A 10.10.16.6 =20
mirkwood IN A 10.10.16.7 =20
printer IN A 10.10.16.8 =20
=3D=3D=3D=3D
/etc/bind/db.10
=3D=3D=3D=3D
; BIND reverse data file for broadcast zone
$TTL 86400
@ IN SOA chaos. root.chaos. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
86400 ) ; Negative Cache TTL
;
@ IN NS localhost.
1 IN PTR moria.chaos.
2 IN PTR gondor.chaos.
3 IN PTR rohan.chaos.
4 IN PTR mordor.chaos.
5 IN PTR lorien.chaos.
6 IN PTR shire.chaos.
7 IN PTR mirkwood.chaos.
8 IN PTR printer.chaos.
=3D=3D=3D=3D
Add to /etc/bind/named.conf
=3D=3D=3D=3D
zone "chaos" {
type master;
file "/etc/bind/db.chaos";
};
zone "16.10.10.in-addr.arpa" {
type master;
file "/etc/bind/db.10";
};
=3D=3D=3D=3D
Step three: Optional
If you want the clients to resolve other domain names as well,=
=20
the client machines can replace the dhcpd instruction.
/etc/dhclient.conf
=3D=3D=3D=3D
# /etc/dhclient.conf for dhcp-client package.
supersede domain-name "lugod.org foo.bar chaos";
