As a Mension, I'm doing some testing in RPi. The final objetive it's to control a motor and some sensor from Internet/Smartphone.
I was searching for information and I decided to use WebIOPi because seems pretty cool.
So,I wanna to make a client using the REST API, so first I'm trying with cUrl to make some testing.
The problems begun when I tried to change the GPIO or get some information. So a set a HTTP POST for example:
curl -v -X POST -u webiopi:raspberry http://10.42.43.112:8000/GPIO/2/function/out
And the output is this:
* Trying 10.42.43.112...
* Connected to 10.42.43.112 (10.42.43.112) port 8000 (#0)
* Server auth using Basic with user 'webiopi'
> POST /GPIO/2/function/out HTTP/1.1

At the moment, I don't seek out anything helpful, So if you know something I missed and wanna help I'll be grateful.
And I tried again with the advices of @SteveRobillard as this (output) : quique ALL=NOPASSWD: ALL and it doesn't work,
quique@quique-Vostro-3500:~$ curl -v -X POST http://10.42.43.112:8000/GPIO/2/function/out
