Issue Log

burble.dn42 now has a public issue log, hosted on the DN42 Registry.

Issue Log

Feel free to raise issues or enhancements on the log.

Speedtest Service

An experimental speed test service has been introduced:

France: https://speedtest.fr-rbx1.burble.dn42
Canada: https://speedtest.ca-bhs2.burble.dn42

The two services are currently only accessible over IPv6 but are hosted on dedicated servers with plenty of available bandwidth. If the service ends up loading or disrupting the rest of the network then I may end up removing it, so use responsibly.

31st December 2019

The Christmas period has been a really busy period for burble.dn42, with integration and transfer of services over to the new nodes. Primarily, this has meant moving services from fr-rbx1 and sg-sin2 to fr-rbx2, fr-sbg1 and sg-sin1. As part of the rebuilding, I’ve also taken the opportunity to re-create most of my ansible scripting, with the intent that this will eventually be published.

24th December 2018

Added new peers:

Dialup Service

Mon, 01 Jan 0001 00:00:00 +0000

Connect in to dn42 using a real physical modem.

06/02/23 - The modem service is currently unavailable and will remain offline until later in the year.

In the meantime, the modem emulator service is still available.

Health warning: dialing in to dn42 can be rewarding and great fun, but using modems over VoIP is flakey at the best of times and getting it to work can be a frustrating experience. This is very much an experimental service.

The burble.dn42 dialup service allows you to dial in to dn42 via a modem. The modem is reachable via VoIP and connected to a PPP server, allowing you to log in and obtain full dn42 IPv4 connectivity.

Peering with burble.dn42

Mon, 01 Jan 0001 00:00:00 +0000

This page provides the information to get started on peering with the burble.dn42 network

burble.dn42 is a set of global POPs integrated to the dn42 network, and new peering requests are welcome. Some details of the network are available in the Design page.

burble.dn42 is a large network and there are some restrictions in place to protect the network and the rest of the DN42.
Please ensure you read the information below before requesting to peer.

DN42

Mon, 01 Jan 0001 00:00:00 +0000

burble.dn42 hosts a number of DN42 infrastructure services.

DNS

Service	Name	IP
DN42 Master	b.master.delegation-servers.dn42	fd42:180:3de0:30::1
Authoritative Service	b.delegation-servers.dn42	172.20.129.1 fd42:4242:2601:ac53::1
Recursive Service	b.recursive-servers.dn42	172.20.129.2 fd42:4242:2601:ac53::53

burble.dn42 provides a local, anycast, authoritative and recursive DNS service.
The DNS Service has it’s own page.

DN42 Wiki Mirror

Mirror URLs
wiki.dn42 wiki.burble.dn42	(editable via DN42)
dn42.dev wiki.burble.com	(read-only via public internet)

burble.dn42 maintains a globally distributed mirror of the DN42 Wiki, and is part of the wiki.dn42 anycast group. The DN42 services (wiki.dn42 and wiki.burble.dn42) are editable, whilst the public internet views (dn42.dev and wiki.burble.com) are read-only.

Modem Emulator

Mon, 01 Jan 0001 00:00:00 +0000

No modem ? no problem.

Dialup services may or may not be available depending on rebuild progress.

If you don’t have a physical modem you can still get that retro vibe by accessing dn42 using the modem emulator service. This service presents a series of TCP/IP ports that emulate a subset of the Hayes AT command set and which are speed limited to specific baud rates. The modem can dial directly to the fr-par1 shell service for that CLI experience, or get full dn42 access via a PPP session.

elburb.dn42

elburb.dn42 is a private domain used for burble.dn42 internal services.

Routing Policy

Mon, 01 Jan 0001 00:00:00 +0000

With a global network and multiple peers, the burble.dn42 network typically has many alternative route paths for reaching a particular destination. The routing policy aims to keep route selection sane, and avoid sending traffic outside of a region where possible.

Policy Objectives

Direct routes for prefixes belonging to a peer should be given the highest priority.
- So that traffic to peer networks is routed over the burble.dn42 network directly to the peer and not via an external 3rd party
Where prefixes are tagged with a DN42 region, they should be routed locally or within the burble.dn42 network.
- To avoid sending traffic across regions when this could have been avoided.
- The AS path length is also increased between regions to pursuade external routers to also prefer local hosts.
Prioritise by shortest path, then lowest latency

Policy Implementation

bgp local_pref

The local_pref for routes is set on entry, and then propogated across the whole network. This forces the network to prefer routes that, where possible, send traffic through the burble.dn42 network to a local peer, rather than sending cross regional traffic through external peers (aka Cold Potato Routing).

BGP Communities

Mon, 01 Jan 0001 00:00:00 +0000

This page describes the use of BGP communities within the network.

DN42 Communities

The DN42 Route Origin Community is applied both internally and externally, and is used to influence the Routing Policy.

Community	Description
( 64511 : 40 < x < 54 )	Route Origin

The other DN42 communities are not used in burble.dn42:

Community	Description
( 64511 : 0 < x < 21 )	Max latency
( 64511 : 20 < x < 30 )	Min bandwidth
( 64511 : 30 < x < 35 )	Min encryption

Well Known BGP Communities

The following well known communities are implemented.

DNS

Mon, 01 Jan 0001 00:00:00 +0000

burble.dn42 provides a suite of DNS services, including running one of the two DN42 DNS master nodes that exports registry information to the DNS infrastructure.

Role	Names
DN42 DNS Master	b.master.delegation-servers.dn42
Authoritative DNS Service	b.delegation-servers.dn42 ns1.burble.dn42
Recursive DNS Service	b.recursive-servers.dn42 dns.burble.dn42
dns64 Service	dns64.burble.dn42

Apart from the Master, all DNS services are anycast across every node to provide fast, local responses network wide. The services support DNSSEC and are available over UDP, TCP, DNS over HTTPs and DNS over TLS.

ACME

Mon, 01 Jan 0001 00:00:00 +0000

burble.dn42 provides an ACME service using an intermediate certificate issued by the dn42 certificate authority and implemented using a HashiCorp Vault cluster to provide a highly available service.

The following ACME challenge types are supported:

http-01
dns-01
tls-alpn-01

dn42 endpoint

https://acme.burble.dn42/v1/dn42/acme/directory

The dn42 endpoint serves certificates signed by an intermediate certificate issued by the dn42 certificate authority.

Note that certificates are issued with a validity period of 30 days, which is shorter than most clearnet ACME services.

Shell Accounts

Mon, 01 Jan 0001 00:00:00 +0000

burble.dn42 provides shell accounts on the following servers:

shell.fr-rbx1.burble.dn42
shell.uk-lon1.burble.dn42
shell.de-fra2.burble.dn42
shell.ca-bhs1.burble.dn42
shell.us-ash1.burble.dn42
shell.us-lax2.burble.dn42
shell.us-nyc2.burble.dn42

There is also an anycast address shell.burble.dn42 that will route to the closest server.

Accessing the Service

The shell service imports user information from the dn42 registry allowing any MNTNER to log in to the servers. Usernames are constructed by lowercasing and removing the ‘-MNT’ suffix.

Using an SSH public key

If you have an auth attribute with an SSH public key, this will be imported from the registry and you can use the SSH key to log in to the shell server.

S3 Object Storage

Mon, 01 Jan 0001 00:00:00 +0000

burble.dn42 provides an S3 compatible storage service based on min.io.

https://minio.burble.dn42 - Web interface
s3.burble.dn42 - S3 compatible interface

Remember that the storage service is provided for the dn42 community and the burble.dn42 abuse policy applies.

Be considerate in your usage so that others will get the same benefits as you are enjoying now. Clean up files that you no longer need, do not use the service for illegal or objectional content and don’t be stupid.

Ping Challenge

Mon, 01 Jan 0001 00:00:00 +0000

Can you solve the burble.dn42 ping challenge ?

To start

$ ping -s 0 -c 1 fd42:4242:2601:31f0::1

Hints

Use -c 1 to only return one ping, unless instructed otherwise
Use -s 0 to create a zero sized ping, unless instructed otherwise
Packet capture is your friend
You may also find a CyberChef useful
The server maintains state based on your source IP and will time out idle clients after several days. There are ways to check the status (revealed during the challenge) but if your state times out you will need to restart from the nearest checkpoint.

Abuse Policy

Mon, 01 Jan 0001 00:00:00 +0000

The burble.dn42 network has a zero tolerance policy on network abuse, both within burble.dn42 and across the wider DN42 network.

Abuse could include, but is not limited to:

Excessive use of resources
Hacking, viruses, trojans etc or any other disruption that could harm or create risk to the services or its users
Distribution of objectional content that could create a civil or criminal liability

The burble.dn42 network owner is the sole arbiter for determining what is deemed abuse and for any mitigations taken.

Privacy Policy

Fri, 18 Dec 2020 00:00:00 +0000

In common with most websites, the burble.dn42 site and associated services may log any access you make and these logs contain your source IP address together with the page or service being accessed. If you are required to log in to access a burble.dn42 service, you should assume that the user id used for the service is also logged. Website and service logs are accessible only by the network administrators and used purely for diagnostic reasons and to prevent abuse. They are not shared in any way. Log retention varies depending on the service, but is at most, 1 month.

Network Design

Mon, 01 Jan 0001 00:00:00 +0000

This page documents a previous iteration of the burble.dn42 network and is currently out of date.

Tunnel Mesh

Hosts within the burble.dn42 network are joined using an Wireguard/L2TP mesh. Static, unmanaged, L2TP tunnels operate at the IP level and are configured to create a full mesh between nodes. Wireguard is used to provide encryption and encapsulate L2TP traffic in plain UDP such that it hides fragmentation and allows packets to be processed within intermediate routers’ fast path.

Things to do in DN42

Mon, 01 Jan 0001 00:00:00 +0000

What can you do in DN42 ? Ultimately, you’ll get out of DN42 what you put in to it, but I’ve listed here a few ideas that may serve as inspiration and the spark an idea.

This is deliberately not a set of instructions or a guide and it’s not a checklist of stuff you must do.
If you are interested in something there is plenty of public information available on all these topics.
