Versions: Unix, Released: 2001.01.07
What: License change, Darwin and Linux fixes, OpenBSD 4.0, MTU support

Future Updates / Wishlist / Known bugs and issues

See also the Changelog that is currently in CVS. Following is a list of items where the SixXS team is currently busy with:

  • New cross platform user interface
  • Test-mode
  • Time-set mode. Uses time from TIC and/or AYIYA to configure time properly
  • Re-try TIC connect but the 'correct' way, thus abort when receiving full errors
  • Additional support for OpenSSL next to GnuTLS (selectable at run and build time)
  • Handle non-existing /dev/net/tun device when udev not active
  • Sanatize incoming data before passing it to system() alike functions, this could be a possible attack vector (reported by Jan Behrens) [one just has to trust us for the time being ;) ]
  • Refetching of configuration data to test if they are still valid.
  • Reconfigure/fetch information on SIG-HUP.
  • L2TP Support (Yes, even under Windows one can do IPv6 in PPP in L2TP :) [works but needs to be 'prettyfied' for release].
  • TSP (Tunnel Setup Protocol) Support [experimental, no demand, thus very low priority].
  • kFreeBSD (FreeBSD kernel, Debian userspace) compile fix by Axel Beckert
  • Windows:
    • Windows AYIYA implementation doesn't route correctly, requires mac-based fixup.
    • Fixup service interface
    • Installer (Binary, Tun/TAP + GnuTLS, Start Menu, Service-Option)
  • Apple OSX / iOS:
