Our registered nameservers are:

hostname aka location IPv4 IPv6
ns1.sugarlabs.org lightwave FSF, Boston, USA 140.186.70.102 2002:8cba:4666::1
ns2.sugarlabs.net sunjammer FSF, Boston 140.186.70.53 2002:8cba:4635::1
ns1.codewiz.org trinity Develer, Firenze, Italy 83.149.158.210 2002:5395:9ed2::1
ns2.auth.osuosl.org - OSU-OSL, Seattle, USA 140.211.166.141 -

Note that ns2.auth.osuosl.org is not under our control and does not serve all our domains.

Hostmasters

  • Bernie Innocenti <bernie@codewiz.org>
  • (others to be added when this documentation is finished)

Editing zone data

We use distributed version control and admin scripts to arbitrate edits to the zone files and nameserver configurations. DO NOT EDIT THESE FILES LOCALLY without first confirming with all hostmasters.

Checkout nameserver config

To simplify merging, each hostmaster pushes to a separate branch:

git clone root@lightwave.sugarlabs.org:/var/lib/bind/etc/bind ns
git config --add remote.origin.push '+refs/heads/*:refs/remotes/USERNAME/*'

FIXME: use an unprivileged group "hostmaster" rather than root.

Edit zone data

Guidelines for editing zones:

  • Please keep the zone files tidy, by following indentation style
  • Add comments as needed to describe obscure records in the zone files
  • Remember to keep reverse zones always up to date
  • Bump the serials after each update!

Push changes back to master nameserver

  • First, update and resolve conflicts, if any:
git pull
  • We push to our own branches and then merge into the sandbox:
git push
ssh root@lightwave.sugarlabs.org "cd /var/lib/bind/etc/bind && git merge remotes/USERNAME/master"
  • Now reload the nameserver configuration, checking for errors:
ssh root@lightwave.sugarlabs.org tail -f /var/log/daemon.log &
ssh root@lightwave.sugarlabs.org /etc/init.d/bind9 reload
