Hello,
Installing Bind is not complex. First of all, you'll want to download an RPM for Bind:
http://penguinman.com/rh9/bind-9.2.3-1.i386.rpm
Once it's finished downloading, you can install it (as root):
rpm -Uvh bind-9.2.3-1.i386.rpmThen you can edit named.conf to configure Bind.
See here for more information:

what is RPM -Uvh bind -9.2.3-1.i386.rpm ?
what is RPM -Uvh bind -9.2.3-1.i386.rpm ?
It's a command you enter at the command prompt to install the rpm file that you've downloaded.
Additionally, you'll need to provide the complete path to the RPM and gain root access, so the final command that you enter might be like:
cd /home/you/Desktop
su
[enter your password here, although it won't show up onscreen]
rpm -Uvh bind-9.2.3-1.i386.rpmReplace /home/you/Desktop with the path to the rpm (where your web browser saved it).
can someone explain the whole conecpt of domains?
On a local area network, when a computer wants to view something other than an IP address, it first looks in its internal DNS routing table. On Linux, this is usually in /etc/resolv.conf . If it can't find it in there, it asks the local DNS server (whose IP address is in its config) for the IP address of this name that it's trying to find. The DNS server than returns the IP address (if it can be found) to the computer.
When you enter a domain into your address bar, the first thing that happens when you press return is your browser sends a lookup domain request to your DNS server.
DNS servers are servers that contain tables of domains and their IP address that they point to, and these DNS servers are all around the world. They all contain the same data, so it doesn't matter which one you use. Usually, your ISP has a DNS server, so that is usually the one your browser uses to lookup domains, as it's the closest.
When the DNS server recieves the request, it looks up in its domain table, finds the IP address, and sends this back to your computer. Now that your browser has this information, it can then communicate directly with the web server to get the website.
so if i wanted to point say, www.ben.net to my fixed IP adress, what would i need to do?
also, is thier any benefit of having domains on a linux LAN as opposed to just hostnames
so if i wanted to point say, www.ben.net to my fixed IP adress, what would i need to do?
On your local DNS server, you would need to edit the /etc/named/named.your.domain and /etc/named.conf and add an entry pointing www.ben.net to your fixed IP address. If you don't know how to do this, try looking here:

also, is thier any benefit of having domains on a linux LAN as opposed to just hostnames
Domains are useful as you can use an entire domain to represent your LAN, and each individual computer can use a subdomain. Or, if you have a larger computer, you can use subdomains for subnetworks inside your LAN. Simply having hostnames works, but it's not as easy to see which network and computer it points to.
Installing the DNS Server - BIND9:
Install a DNS server - BIND9:
apt-get install bind9
Check the server
Linux Terminal:
ping localhost
Go to the directory "/ etc / bind" (sometimes "/ etc/bind9").
Review the bind configuration files in this directory.
II. DNS server configuration - BIND9:
5th Edit the configuration file "named.conf":
Using the editor, please look at this file
At the end of the file before the line "include" / etc / bind / named.conf.local "," please add
the following lines:
zone "200.168.192.in-addr.arpa" {
type master;
file "/etc/bind/200.168.192.in-addr.arpa";
};
zone "201.168.192.in-addr.arpa" {
type master;
file "/etc/bind/201.168.192.in-addr.arpa";
};
zone "zz.lab.vs" {
type master;
file "/etc/bind/zz.lab.vs";
};
where "zz.lab.vs"
eg for animal group = 1, the name will be as follows:
z1.lab.vs
6th Creating and editing a configuration file "200.168.192.in-addr.arpa ':
The file should contain the following lines:
$TTL 1s
@ IN SOA localhost. root.localhost. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
yyy IN PTR localhost.
yyy IN PTR hostn1
yyy IN PTR hostn2
where "yyy" is the last byte address assigned to the team "192.168.200.yyy"
7th Creating and editing a configuration file "201.168.192.in-addr.arpa ':
The file should contain the following lines:
; BIND reverse data file for local loopback interface
;
$TTL 1s
@ IN SOA localhost. root.localhost. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
1 IN PTR localhost.
1 IN PTR host1
2 IN PTR host2
3 IN PTR host3
8th Creating and editing a configuration file "zz.lab.vs"
The file should contain the following lines:
;
; BIND data file for local loopback interface
;
$TTL 1s
@ IN SOA ns.zz.lab.vs. root.ns.zz.lab.vs. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
IN NS ns
localhost IN A 127.0.0.1
ns IN A 192.168.200.yyy
host1 IN A 192.168.201.x+1
host2 IN A 192.168.201.x+2
host3 IN A 192.168.201.x+3
hostn1 IN A 192.168.200.yyy
hostn2 IN A 192.168.200.yyy
where "zz.lab.vs"
eg for animal group = 1, the name will be as follows:
z1.lab.vs
9th Restart the DNS server
