content: I just realized that my Rigol DSA815-TG allows add-on licenses to be entered remotely via SCPI commands:The command below install the option (the corresponding option number is 0001) of which the serial number is UADEYSAZQABRJACQTAWJZLLPBCVA.:SYST:LKEY "UADEYSAZQABRJACQTAWJZLLPBCVA"I realize with a 26 alphanumeric key, it is unlikely enough keys/sec could be sent to do a successful brute force, but perhaps someone more experienced than I can confirm that? Over USB.Cheers

content: To successfully test every possible combination, unless you find some pattern to valid ones that lets you eliminate a whole hell of a lot, you would have to test them at a rate of 1.32 × 1032per second, or 132 kilo-giga-giga-gigahertz, to get them all done in a year.

content: After counting, I notice there's actually 28 characters... so 1.19 x 10^36 per second for a year actually. Ok smarty-pants, fuddle duddle

I doubt you would be saving mr. jones a lawsuit by being a nervous nelly

content: I agree with you. Personally, I am of the opinion that if you bought something, you should be able to do whatever you damn well please with it, and if the people who sold it were hoping you wouldn't find out how to get at its locked-away abilities, well, sucks to be them. If I bought a house with a locked door and was never given the key, I could take the lock out.You do not need to personally attack people who do not agree with you. That isn't a good way to make friends. We want to be friendly here, now don't we?

content: Quote from: ftransform on March 14, 2013, 04:42:42 amI typically expect people to have a thick enough skin to lightly argue and debate things, but I try not go accusing them of being rats. I wouldn't call someone thin-skinned because they get upset by that.Quote from: ftransform on March 14, 2013, 04:42:42 amThat's precisely what I was thinking of

content: I bet that serial numbers are generated with some pattern, maybe the 'real' serial number (like 0002256) signed/encrypted with some assymetric crypto. If you find a way to break it expect two things to happen:a) nobel prize in mathematics (besides the fact that there is no nobel prize in math, but rather Fields Medal)b) bullet in the head from any of intelligence agencies
