| ## AutoAP Next Gen by kuthulu/Iron, supported by wo-fo, infusion, drats, cid12, mathilda ## | |
| ## This script is inspired by the autoap script that stoped working after the command ## | |
| ## set of the "wl" was reduced in the DD-WRT V2.4 Beta firmware on the 18th of June 2007 ## | |
| ## ## | |
| ## http://sourceforge.net/projects/autoap ## | |
| ## ## | |
| ## AutoAP NG is a script that enables users to automatically log into different AP's ## | |
| ## that provide internet access. The AP's can be automatically searched or set in a list ## | |
| ## ## | |
| ## Terms and Conditions: ## | |
| ## AutoAP can be used, modified and distributed freely for private or commerical purposes ## | |
| ## ## | |
| ############################################################################################## | |
| version="2009-07-11" | |
| # Todo: | |
| # - Test script in all modes (AP, client, repeater etc.) | |
| # - Test connection to WEP/WPA protected AP | |
| # - Check network setup for G/mixed/B etc. | |
| # - Connect to AP with specific MAC address | |
| # - Deny other AP's macs with the same SSID. Fixed and dynamic list. | |
| # - Give mac with preferred SSID(ssid*key*mac combination?) | |
| # - Configure via web GUI | |
| # - Use non volatile storage for history | |
| # - Make script to create different versions: Micro, copy to rc_startup, cat | |
| # - GPIO/logreverse on the fly change not allowed | |
| # - Test! | |
| # | |
| # Idea's | |
| # - Smarter html refresh, server push? | |
| # - Use LED's to signal status (Ilja: hard for different router models!) | |
| # - What to do with the idle time? | |
| # - Using ping times to select a AP | |
| # - Mesh networking | |
| # | |
| # Latest changes: | |
| # | |
| # 2009-7-11 (kingsmill) | |
| # - fixed scripting errors result from apply changed settings from the cgi web script. | |
| # changed the for loop to a while loop | |
| # | |
| # 2009-6-28 (Ilja) | |
| # - $aap_possid and $aap_prefssid finally work again... The missing IFS=" " was | |
| # spoiling the correct parsing of these entries | |
| # | |
| # 2009-06-21 (Ilja) | |
| # - Changed such that it runs with the newer versions of dd-wrt... | |
| # | |
| # 2009-06-20 (andreev2001) | |
| # - Changed "eth1" to "$(nvram get wl0_ifname)" | |
| # | |
| # 2009-05-06 (RNR aka Drats) | |
| # - Fix for aap_maxfailed = 0 problem | |
| # which ignores number of failed connection attempts | |
| # | |
| # 2007-10-10 (RNR aka Drats) | |
| # - Added code to include a list of possible WEP sites to include in the sort order | |
| # | |
| # 2007-07-28 (kuthulu/Iron) | |
| # - Completely rewritten | |
| # | |
| # 2007-07-18 (kuthulu/Iron) | |
| # - modified to use site_survey in stead of wl | |
| # | |
