Service/Nameservers

Registered nameservers

The following nameservers are currently registerted in whois records for our domains:

(FIXME: this is what it should look like after the current transitional mess)

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, ANY CHANGES WILL BE OVERWRITTEN.

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, commit your changes:

git commit -a

• Update from remote to 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 & /etc/init.d/bind9 reload'

• You should see the slaves transfering the new zones you have modified

TODO: document what to do for changes to slaves config.
