Location: ServerBeach and a Colo in Detroit
 
 
Servers: ns1.fedoraproject.org, DNS1.J2SOLUTIONS.NET
 
 
Purpose: Provides DNS to our users

{{Admon/note |  Note, dns1.j2solutions.net is not run by Fedora's Infrastructure Team.  Its resources have been donated by Jesse Keating.}}
 
 
=== DNS update ===
 
DNS config files are puppet managed on puppet1.  The update is standard to the puppet configs at http://fedoraproject.org/wiki/Infrastructure/Puppet/QuickStart
 
 
From puppet1:
 
<pre>
 
git clone /git/puppet
 
cd configs/dns/master
 
vi fedoraproject.org # Don't forget to increment the serial!
 
cd ../..
 
cvs commit -m "What you did"
 
make install
 
</pre>
 
 
It should update within a half hour.  You can test the new configs with dig:
 
 
 
<pre>
 
dig @ns1.fedoraproject.org fedoraproject.org
 
dig @dns1.j2solutions.net cvs.fedoraproject.org
 
</pre>
 
 
 
== resolv.conf ==
 
 
In order to make the network more transparent to the admins we do a lot of search based relative names.  Below is a list of what a resolv.conf should look like.
 
 
{{Admon/important | Any machine that is not on our vpn or has not yet joined the vpn should _NOT_ have the vpn.fedoraproject.org search until after it has been added to the vpn (if it ever does)}}
 
 
=== Phoenix ===
 
<pre>
 
search fedora.phx.redhat.com vpn.fedoraproject.org fedoraproject.org
 
</pre>
 
 
=== Non-Phoenix ===
 
<pre>
 
search vpn.fedoraproject.org fedoraproject.org
 
</pre>
 
 
The idea here is that we can, when need be, setup local domains to contact instead of having to go over the VPN directly but still have sane configs.  For example if we tell the proxy server to hit "app1" and that box is in PHX, it will go directly to app1, if its not, it will go over the vpn to app1.
