i didnt really understand your answer. should i do that with a new stick or the unpacked one?
Doesn't matter. The only difference is that the 'packed' version will first be unpacked before the first reboot.
also, i cant retrieve the backdoor password, nothing happens when i open mykey.php in a share browser through the web interface.
PM me your MAC addess, I'll PM you your password.
and again what would the name and the location of a logfile be? and how do i change permissions to access it?
There is no logfile. The reloader script doesn't create one, and so any logfile you can find is created by Debian itself, in which case the reloader script has done it's job.
If you don't have permission to read a logfile, I don't think you can get that through the webinterface. Using the backdoor you have all permissions. But you can also put the stick in any Linux computer, and read the file as root.
