  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 www.UID.uncc

  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! • If you do the lab in multiple sessions • Watch out for DHCP changes!

  4. Hints: • Read the notes page for updates and hints • Last page in lab • 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: • Need a 172.16.0.0 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 reuse the 172.16.1.xxx address given by DHCP (assign as static) • Only if you complete this lab in one period • Danger of someone else getting this address after lease expires -- or -- • Can use a 192.168.pcNN.xxx address • Hint: use your modified scripts from Lab 8 to switch from DHCP to static quickly and easily! • Lab example uses 192.168.50.128 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!!!
