AICCU - Automatic IPv6 Connectivity Client Utility

AICCU

AICCU (Automatic IPv6 Connectivity Client Utility) makes it easy for users to get IPv6 connectivity. After having requested an account, tunnel and optionally a subnet, AICCU can be used to automatically configure the tunnel. AICCU supports TIC (Tunnel Information & Control protocol), which it uses for retrieving the tunnel configuration information, AYIYA, which allows tunnels to be created even behind firewalls and NAT's.

AICCU uses The GNU Transport Layer Security Library to secure TIC communications. GNUTLS Logo

License

This software comes with an Open Source LICENSE.

Notes

Please read the README that is included with AICCU. Following is an important section of that text:

WARNING: Never run AICCU from DaemonTools or a similar automated 'restart' tool/script. When AICCU does not start, it has a reason not to start which it gives on either the stdout or in the (sys)log file. The TIC server *will* automatically disable accounts which are detected to run in this mode. Use 'verbose true' to see more information which is especially handy when starting fails.

Please also heed the notice in the TIC FAQ which explains what happens to clients that connect repeatively.

Downloads

Latest Windows console version: 2012.02.02
Latest UNIX/Console version: 2007.01.15

Alternatively to the above links, one can also access the AICCU download archive directly for older and alternative versions.

Next to the these editions there are various routers on the market, on a store shelf near you, that have AICCU built in and have web interface options to configure it.

An example configuration file: aiccu.conf
For the Windows version store as c:\windows\aiccu.conf or in the same directory as the binary.
For the UNIX versions store in /etc/ or the path which got configured at compile time.

Alternatives

Below listed are a few alternative implementations of the TIC/heartbeat/AYIYA protocols that can be used instead of AICCU.

  • AVM Fritz!Box
    • Embedded into AVM Fritz!Box with easy configuration from web interface
    • Custom implementation (read: not based on AICCU)
    • Supports TIC and heartbeat (no AYIYA support)
  • Android Android
    • IPv6Droid
      • Available from Google Play Store
      • Android 4.0+ (due to VpnService) tested till 5.0
      • Custom implementation of TIC and AYIYA protocols in Java using VpnService
      • Does not require rooting of device
      • Provided by Andreas Feldner
    • Androiccu
      • Available from Google Play Store
      • Android 2.2 and up (last updated 12 June 2013 though)
