Errr - sledgehammer & walnut anyone?
What's the point in implementing networking just to do a bruteforce
crack on a *serial* connection? Has the world gone mad? Is it *really*
that hard to write a bruteforcer in C or script language?
I'm not having a go, it just strikes me as a bit of overkill, considering
you *used* to be able to get a bruteforcer for the KX-TD 1232 at pbxsoftware.com (incidentally I may have the archive somewhere so mail me if you urgently
require it) and you could write a cracker in Telix script in under 20 lines.
The KX-TD allows infinite password attempts from what I recall and I also
seem to remember it's either a 5 or 7 digit password (default 12345..)
My home-rolled script can crack one in under an hour over dialup at
which point you just roll on in with Programmator.
Nice to see a PBX saying "Welcome" at login :)
