Lab 10 Overview DNS

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

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!

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

Notes: 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!!!

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
