license required for BSD unix?

[Jonathan I. Kamens]

  You need two licenses in order to be able to get the full BSD sources. 
First of all, you need a source license from AT&T.  This is *very* expensive
for commercial sites, and somewhat less expensive (although still not a
negligable amount of money) for educational institutions.

  Once you've got the AT&T license, you sign a license agreement with Berkeley.

  The reason you need an AT&T license is that the BSD source code has some
AT&T code still in it.  CSRG at Berkeley is trying to remove as much of that
code as possible for 4.4BSD; I don't know if they're going to succeed in
removing all of it.  If they do, the AT&T license will no longer be necessary,
and I suspect they'll charge only distribution costs for the sources.

  Incidentally, as they free parts of BSD of AT&T code, the put it onto
uunet.uu.net in the /bsd-sources directory (although I don't know how often
they update it).  So there is a lot of code there you can browse through that
is freely redistributable.

  In any case, the right people to contact to talk to about questions like
these are:

        Distribution Coordinator
        Computer Systems Research Group
        Computer Science Division, EECS
        University of California
