Hello, My name is Jia. I would like to know about the licensing restrictions for Linux/Red Hat. I am not an user however I am in school and redeveloping the automation of a business. My team and I chose to use Linux/Red Hat and I need to know if there is any licensing restrictions for this program. Whether it comes with one license and others have to be purchased separate and so forth. Whoever can help I will greatly appreciate it. Thank you.

all linux distributions are released with the core of the os under the gnu=gpl.
http://www.gnu.org/licenses/gpl.txt

Red Hat's own tools may or may not be under the gpl.
check the licensing for the particular tools you will need.

most allow for free distribution, as long as you don't try to claim ownership or make it proprietary.

The definitive source of information would be .. Red Hat itself.

I went to http://www.redhat.com, typed "licensing" in their Search box, and found all kinds of very interesting stuff.

The thing to remember about any software configuration is that parts of it may be free while other parts are not. And, instead of popping into a knee-jerk "yuck!" reaction at the thought of having to pay for something software, what you want to do instead is to consider what you get for what you are being asked to pay for. I'm not telling you what to decide, only that you should methodically look.

As an example, it's clear that Red Hat is courting the corporate client, who is probably running a very large number of systems and may, on some of those systems, have intensive performance requirements. Do you meet one of their profiles? If so, you might decide that what they're selling is, for you, an excellent buy. Or you may decide that it is not.
