How can I practice administering HP HP-UX and IBM AIX?

Question

*nix-like systems

Please tell me the services that provide free / paid access to remote terminals of these operating systems for training.
Maybe as part of some training courses?
Preferably cheaper, because I want to do this in order to broaden my horizons in Unix operating systems.
There seems to be literature, but there is nothing to practice on.
Or maybe I don't need it at all? I don't have a specific goal, just curiosity.

Answer 1

These systems have fairly complete documentation and vendor support was purchased where they are, so if you are suddenly lucky to encounter them live, you will figure it out, I don’t see the slightest sense in specially mastering, firstly, unused knowledge is quickly forgotten, secondly, they are so little common that you are unlikely to be lucky enough to see them live. If you want to get to grips with Unix, FreeBSD is the closest thing in mass use.

Answer 2

dying systems there is no point in practicing, master Linux and you will feel comfortable in any niks system.

Answer 3

Practice in a production environment or buy a used IBM Power, see in advance that support is aix latest versions. About the fact that aix is ​​dying is nonsense. See job vacancies on indeed on the topic aix.
