NetBSD v3 users - check the IPv6 tun/tap patch on http://www.sixxs.net/archive/sixxs/aiccu/unix/ - Windows GUI client: - Just run and follow the dialogs. - Window GUI client as a service: - Run the GUI client without options. - Choose all the correct settings and check that the tunnel works. - Select the "Auto Enable" button on the info page. - Select the "Save Configuration" option from the menu. (See screenshots for its location) - Quit the GUI. - Install it as a service using "aiccu /i" - Then use "net start aiccu" or start it from the service control manager (services.msc) One can uninstall the service with "aiccu /u" and of course use the start/stop options to start/stop it. - Unix/Windows console client: - Edit /etc/aiccu.conf and fill in the required values. - Run aiccu test; aiccu start If there any problems: - read the SixXS FAQ at http://www.sixxs.net/faq/ - check the SixXS Forum at http://www.sixxs.net/forum/ If then it still fails, contact the SixXS staff as described per http://www.sixxs.net/contact/ For problem reports please read and use the "Reporting Problems" section on that page to determine where the problem occurs. aiccu/doc/LICENSE0000664000175200017530000000273210550204777013657 0ustar jeroensixxsdevThe SixXS License - http://www.sixxs.net/ Copyright (C) SixXS Staff All rights reserved.

It uses the TIC (Tunnel Information & Control) protocol to request the information needed to setup a tunnel through which the connectivity is created. AICCU supports the following tunneling protocols: - 6in4 static (RFC 2893) - 6in4 heartbeat (RFC 2893 + draft-massar-v6ops-heartbeat) - AYIYA (draft-massar-v6ops-ayiya) As AYIYA even works from behind NAT's, thus unless there is a very restrictive firewall in place, anybody should be able to get IPv6 connectivity without problems and everywhere they want. 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. The main AICCU page, containing information, screenshots, updates and of course the software itself, unix source + binaries/packages and Windows binaries, can be downloaded from: http://www.sixxs.net/tools/aiccu/ Author ~~~~~~ The author of this code is: Jeroen Massar SixXS Staff http://www.sixxs.net/ With patches accepted from other sources as can be found in the changelog.

It uses the TIC (Tunnel Information & Control) protocol to request the information needed to setup a tunnel through which the connectivity is created. AICCU supports the following tunneling protocols: - 6in4 static (RFC 2893) - 6in4 heartbeat (RFC 2893 + draft-massar-v6ops-heartbeat) - tinc (http://www.tinc-vpn.org) - AYIYA (draft-massar-v6ops-ayiya) As AYIYA even works from behind NAT's, thus unless there is a very restrictive firewall in place, anybody should be able to get IPv6 connectivity without problems and everywhere they want.

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 NATs.
