I'm trying to setup a basic Captive Portal on OpenWRT using IPtables and LUA.
I was able to create a simple Hello World script working in /www/cgi-bin/, but I don't understand how to access server variables.

The script I'm trying to port to Lua is created by Andy Beverly:

I don't like the idea of getting PHP to OpenWRT and I think this should be able to work in Lua.
Any pointers or tips are welcome.

Also, I think this might be a nice add-on for OpenWRT. I've not seen a light weight Captive Portal yet for OpenWRT.

Thanks.
Stu.

Here is a very simple one (NoDogSplash):

WiFiDog is a bit more heavy....

Likely something is already available to meet your needs.

Yeah I know about NoDogSplash, but it's only a splash screen, there's no accounting done here.
True, the script I linked to is very simple, but at least it gives me some level of control on who uses it.

Anyone?

Let me make the question a bit more specific.
What is the equivalent in Lua of PHP variables such as $_SERVER['REMOTE_ADDR'], $_SERVER['REQUEST_URI']?

Thanks!

os.getenv("REMOTE_ADDR") and os.getenv("REQUEST_URI"). For a list of CGI-exported variables see http://nbd.name/gitweb.cgi?p=uhttpd2.gi … proc.c#l56 and http://nbd.name/gitweb.cgi?p=uhttpd2.gi … roc.c#l102
