the big picture

What is this all about?

mc.fly will some day write some stuff about it. In case you have awesome ideas just add them.

For now, an overview picture of the currently connected nodes: http://172.31.2.1/chaosvpn.png (from inside ChaosVPN; updated once per hour) There is also a ChaosVPN internal wiki available at http://172.31.0.24/


ChaosVPN 2.0

redesign

The Rebuild of the ChaosVPN became nessesary at some point, as the vermittlung was blackholed. Furthermore we would like to put live back to the ChaosVPN and use it to interconnect the hackerspaces.

So we thought its a good time to redesign stuff. We will climb up to tinc 1.0.13.

software

An unfinshed Howto for Debian systems is available at Debian - users of other systems need to adapt it likewise, more documentation will hopefully follow in the future.

tinc

we use tinc. There will be a tinc 2.0 version soon. The developer has his ideas about tinc 2.0 at http://tinc-vpn.org/goals/ and first code is at http://tinc-vpn.org/git/fides.

OpenWRT Packages

Blogic will build a special OpenWRT package, which is called chaosvpn at the moment, a recent tinc 1.0.13 is already available in the openwrt packages repository.

See also http://0x1.net/openwrt Packages may be in flux for awhile, if you have trouble with any of the binaries, email cjp.

Debian Packages

There is a long description how to install on a Debian System: DebianHowto

Haegar created (backported) tinc 1.0.13 packages for Debian. They are availible at:

Please note that the above packages may need further backported packages, all of them are available in other subdirectories on debian.sdinet.de.

Pre-Created ChaosVPN program packages, updated every now and then:


fonera20n

Full Setup Instructions: Fonera

Fonera 2.0n 2.3.5 firmware with chaosvpn 2.0 and tinc 1.0.13, tested. No clobber of configs using upgrade script.

Grab here: http://www.agoralink.org/20100417_FON2303_2.3.5.0_DEV.tgz

For the fonera 2.0n http://www.aculei.net/~mjoyce/chaosvpn/

Included are Packages for ChaosVPN, and TINC There are source code packages as well.

Packages go in /openwrt/packages/ Source goes in /openwrt/dl/

.config is a sample config for fonera2n. It is not minimalist in any way. Vyrus has a minimal config I will hunt down.

The chaosvpn version is not reflected in the name of the package... that is just there because I was too lazy to update the chaosvpn package for the current version.

ArchLinux

helios maintains an AUR-package: http://aur.archlinux.org/packages.php?ID=33307

Gentoo

See GentooHowto

sources

The source code repository is available at: http://github.com/ryd/chaosvpn

You can download the source with git 

git clone git://github.com/ryd/chaosvpn.git

IRC

irc.hackint.hack (172.31.98.1)

VoIP

Asterisk servers allowing incoming and outgoing calls to POTS in Hannover and Hamburg hackerspaces. Ask the admins for more information.

Requested applications

During Chaos Communication Camp 2011, participants of the ChaosVPN workshop suggested various applications:

  • Mirrors of interesting public FTP/WWW sites
  • Bittorrent trackers
  • Email (either transparently route email from public domains via ChaosVPN, or have .hack email addresses)
  • Censorship detection: service to request a public webpage from proxies at several nodes at once, compare the differences
  • GeoIP avoidance?
  • Social networking things
  • Varnish cache
  • LDAP (maybe to allow authenticating hackers against their own hackerspace's LDAP server, like Eduroam)
  • Multicast services (limited support in tinc, not automatically forwarded to the LANs)
  • TOR entry nodes in ChaosVPN
  • NNTP (already available on dn42)
  • More games!
  • Distributed computing (BOINC, GRID stuff)

wanted changes

short term

  • clients don't have to authentificate themself - everybody can see the config.
  • if admins are lazy and don't rebuild the config file properly we will have old routes in the network that don't dissapear (at least until the tinc is reconfigured and restarted) (not a problem anymore with a current .git snapshot, the problem will only affect the non-updating participant with it)

long term

tinc does have some problems. That is the reason why we want to replace that in the forseable future. That will be ChaosVPN 3.0

  • Participants can fake network ranges my intention or mistake. (control informations inside tinc are not proper authentificated) (not true anymore with latest chaosvpn.git where we do not import infos from the tinc-network anymore (TunnelServer=yes))
