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
- make prod
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.
