.noise - Noisebridge's Custom TLD

This [[wp:TLD|TLD]] works on Noisebridge's WiFi network(s), providing convenient DNS names for hosts within the subnet <code>10.21.0.0/23 (10.21.0.0 - 10.21.1.255)</code>, which we use for both the WiFi network and internal LAN. For more details, see [[Resources/Network]].

Several servers are hosted at noisebridge with the `.noise` TLD:

* einhorn.noise hosts some VMs (unicorn in German; not to be confused with the former server [[Unicorn]]).
* ml1.noise and ml2.noise provide access to shared-use GPUs.
* [[Olympus]].noise manages the door access control system.

To verify that your host can resolve the .noise TLD to the local network's DNS server, you can perform the following tests:

<pre>
#!/bin/bash

# Check if .noise TLD resolves with default DNS
if nslookup example.noise > /dev/null; then
echo ".noise TLD resolves with default DNS"
else
# If not, test if querying 10.21.0.1 will resolve it
if nslookup example.noise 10.21.0.1 > /dev/null; then
echo ".noise TLD resolves when querying 10.21.0.1"
else
echo ".noise TLD does not resolve with default DNS or 10.21.0.1"
fi
fi
</pre>

For hosts with hardened DNS settings, DNS query exemptions can be configured using <code>dnsmasq</code> to route requests for .noise domain resolution exclusively to the gateway router's DNS service at 10.21.0.1. Here is an example configuration:
<pre>
# Configure dnsmasq to use the local DNS server for .noise domains
server=/noise/10.21.0.1
</pre>

To apply this configuration, follow these steps:

1. Install dnsmasq on your system

2. Create a configuration file (e.g., <code>/etc/dnsmasq.conf</code>) and add the above configuration lines.

3. Restart the dnsmasq service to apply the changes.

With this configuration in place, your host will use noisebridge's local DNS server for .noise domains, while preserving the host's global name-resolution settings.

Contributions with further configuration examples, including GPT-generated output, are welcome.
