Hey,
to obtain a fresh IP from my provider I need to change my MAC. I wanted to do this using only LiveHeader. This was somewhat troublesome, since there is no easy way to get a random number and I didn't find a good solution on the forum. However I figured out a way to do this that I would like to share.
The idea is to load a page containing a pseudo-random value from the router (In this case I use the seconds of the current time). Then parse it to set a random variable and use that to set the mac to a random value. This is steps 2, 3 and 4 of my script.
I hope this information is of some use to people with a similar setup. I think it would be a good addition to LiveHeader to have a variable that gets replaced with a random number. I could submit a patch if a dev tells me how to do it.
