1. Lab 10 Overview
DNS

2. DNS name server Set up a local domain name server
. is the root domain
.lab is the WH302 lab’s TLD (top level domain)
hades.lab is the lab’s domain
In this lab you will create and configure a domain name server on your Debian VM
Same Debian VM as your Apache Web server
Your domain name will be UID.uncc
UID is to be replaced with your lab logon id
Host name will be

3. Hints: Debugging errors on this lab will be the hardest part
Typos
Leaving out key parts in file
The . is critical to end the name in many of the configuration files
. notes the root!
Read the log files for errors that may have occurred!!!!
/var/log/syslog
/var/log/messages
 usually gives a hint of where typos are!

4. Hints:
Read the notes page (last page) for troubleshooting hints and other advice
HEED ITS ADVICE!!!!
Run the VM from /scratch
BAD THINGS WILL HAPPEN IF YOU DON’T
Be sure to change your DNS entry on your clients
NOTHING WILL WORK IF YOU DON’T
If it doesn’t work, do the trouble-shooting
Reading the messages will give a big hint where the errors are!!!!!
Especially the syslog

5. Notes: Always make a backup copy of a config file before editing!!!
Need a address to install Bind 9
Given automatically by DHCP from Hades
DNS servers need Static addresses
Any address will work e.g. 172 (Class B) or 192 (Class C) addresses
Can use the nn.xxx address given by sheet -- or --
Can use a pcNN.xxx address
Hint: use your modified scripts from Lab 8 to switch from DHCP to static quickly and easily!
Lab example uses and jxia3
Change the address to match your static address
Change the domain name to match yours
At the end of the lab you will be able to browse your web site with a host name instead of the IP address.
Note the deliverables on page 4 before starting lab!
Be sure to document CLI items with text, GUIs with screenshots!
Always make a backup copy of a config file before editing!!!

6. Notes: This DNS server will be adequate for a local network
It is insufficient for the Internet!
Does not do zone transfers!
Is missing several other features also
No glue records
Tells the IP address for the DNS
Prevents looping
