BIND is a DNS service that is used on many different distributions of Linux. BIND stands for Berkeley Internet Name Domain. When I setup my home network, I wanted to have a local DNS server. I installed BIND on my 9.04 Ubuntu server. This is a list of commands that I have found helpful for trouble shooting and managing my DNS server. (Note: All of the commands are being executed in a terminal window.Copy and paste the code after the # symbol into a terminal window.)
How to find what version of BIND you are running: # nslookup -q=txt -class=CHAOS version.bind. 0 How to Restart BIND DNS service: # service nscd restart # sudo /etc/init.d/nscd restart How to Start and Stop BIND DNS service: If you are running BIND v.8 or less: # ndc stop # ndc start If you are running BIND v.9: # rndc stop # rndc start How to view the cache of the BIND:For this we will create a dump file and then will need to view the file. Creating the Dump file:
# sudo rndc dumpdb –cache (Note: This will create a dump file called named_dump.db. This is often located in /var/cache/bind.) Viewing the dump file:# cat /var/cache/bind/named_dump.db How to Clear the Cache of BIND: You can just restart the service using the restart command. # sudo /etc/init.d/nscd restart If you think some other commands should be added to the list please send me an email and let me know. Thanks for reading!
