At work I have a Debian box, which serves as sniffer, logger, data injector and a whole array of other odds and ends. All the stuff it's not possible to coerce the company-issued standard Windows box to do.
That's nice. Linux happily goes to work and gets the job done.
Now, my company recently merged with another american company. And as a consequence of this, new, strict regulations apply to what tools we're allowed to use.
This includes ONLY properly licensed software....
