Most of the licenses should be either GPL, LGPL, BSD modified, or other open source license like the PHP license or the Perl license. Mysql is on the Knoppix CD and is GPL. However, there may be content licensed under a non-comercial use license. I would guess that Adobe acrobat reader included with Knoppix is under such a license. With all of that in mind ...
