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.

Nice trick.

drbit's described another trick in "Random values at MAC spoofing on LiveHeader".

Thank you very much for the script!

Old Thread....
I Have a nice trick for jd2:


use %%%random:<length>:<possiblechars>%%%

Example:

Randomnumber length 20:

%%%random:20:0123456789%%%

Random hex 8 byte:

%%%random:16:0123456789ABCDEF%%%
Random MAC:


%%%random:2:0123456789ABCDEF%%%-%%%random:2:0123456789ABCDEF%%%-%%%random:2:0123456789ABCDEF%%%-%%%random:2:0123456789ABCDEF%%%-%%%random:2:0123456789ABCDEF%%%-%%%random:2:0123456789ABCDEF%%%

Can someone explain what this command is doing:

n: [0-9]+:[0-9]+:([0-9][0-9])

It creates a 2 digit number i believe and the author claims it takes the randomness from a websites seconds. But i dont see how it finds the seconds on that side.

I cant use this like it is now because my router (LinkSys E3200) has the rule, that the second digit of every mac-number has to be one of these values: 02468ACE
If i force another value i cant access the router anymore to change it and i dont get internet access.

So i would have to change the var somehow. Maybe take it * 2 so its an even number for sure and somehow making sure its 2 digits only

I dont like the double change approach shown in other thread because it takes double the time.

And im not sure if i should change to JD2 since its new and many complaints seem to be there still.

So i think this solution here would be best if i could adapt it.

i really need script for this modem TB-link:TD-W8951ND
thanks

similar solution via external batch-file: https://board.jdownloader.org/showthread.php?t=29493

if you have a modem, that only changes his IP on a different MAC,
you need to do this:

1) logon your router
2) change MAC
3) reboot router

4.1) logon modem
4.2) reboot provider modem
(or buy a LAN controlled powerswitch to turn on and off)

depending on your modem/router and firmware, you need to figure out the **External links are only visible to Support Staff**
