DNS configuration is stored in '''/afs/bx.psu.edu/service/dns'''


Production data is stored under ''prod/''


Each dns server (ns1, ns2, ns3) runs a script every minute that creates a new PAG, gets a kerberos ticket, afs token, and then runs '''/afs/bx.psu.edu/service/dns/scripts/cron-update-dns.sh'''. This copies over ''named.conf'', and rsyncs the zone files, performing an ''rndc reload'' only if necessary.


'''/afs/bx.psu.edu/service/dns/scripts/export-to-prod.sh''' is used to perform a ''git pull'' under ''prod/'', then releases the svc.dns volume.


To make changes to dns:

* ''git clone /afs/.bx.psu.edu/service/dns/bxdns.git''
* make changes
* ''git commit [<filename> -m <comment>|-a -m <comment>]''
* ''git push''
* ''/afs/bx.psu.edu/service/dns/scripts/export-to-prod.sh''


Afterwards, make sure to do a ''git pull'', or a ''git fetch'' followed by a ''get merge'' afterwards to help avoid merge conflicts when pushing to the central repository.
