non commercial use

Hi all,
what means to qualify for a Non-Commercial Version License you must use the software solely on a system under the Linux, FreeBSD, NetBSD or OpenBSD operating system (whether for commercial or non-commercial use)? Can you give-me an example?
If I use a ssh server on a server linux can I use a non-commercial version license or I need a commercial version? Thanks for all
