See Firmware Wants for a description of what we're hoping to be able to implement with our web admin page.
The code for the web admin is hosted here:
Luci
Luci is the web admin framework that OpenWrt ships with and seems to be a popular choice among other projects. It is written in Lua, which is a sort of procedural language that's kind of a mix between javascript and ruby (??).
All of the Luci code is contained on the router in /usr/lib/lua/luci
Documentation related to the Luci project can be found at:
Its a MVC framework, and files are separated into controller/ model/ and view/
There's a fairly similar package that we can probably take some cues from:
We'll likely need every AP to serve a private WPA encrypted AP even if users have their own home router so that they can config the routers securely.
Debugging
Luci is run as a cgi script. The script is at:
/www/cgi-bin/luci
Luci has a caching system, which should be disabled when debugging, to ensure that requests are not being answered from the cache. To disable caching, change /www/cgi-bin/luci by commenting out the following lines:
-- require "luci.cacheloader" -- luci.dispatcher.indexcache = "/tmp/luci-indexcache"
You can run /www/cgi-bin/luci from the command line like so:
REQUEST_URI="/cgi-bin/luci HTTP/1.1" QUERY_STRING="username=root&password=<password>" /www/cgi-bin/luci
The wikipedia article for CGI has a list of other environment variables that can be set to pass data to a cgi script.
