Welcome to the Community!
Do you mean 4 computers/servers on a shared backbone which goes thru a common router/gateway to the Internet?
Are they each individually and directly accessible from the Internet, or are services on 3 of those passing thru the 4th which is acting as a gateway for outsiders to reach their services?
Hello Eric M, Just a Private Network for me to use and Learn with at home.
Lucky you! Nice playground!
I am sure you will enjoy the adventure of exploring Linux’s capabilities and flexibilities.
It’s going to be Great when I can get “Into Gear” with all my Medical Problems Eric M.
I’ve been a sometime member of PLUG, The Perth Linux User Group, which fosters
the Use of Gnu/Linux. Are you in W.A. or somewhere else Eric?
Welcome to our community @Crabby
I’m trying to figure all this stuff out. I hope you all will be patient with me. Thanks.
Welcome to our Linux community forums, @snowrat58
You have already figured out how to make a post so you are well on our way.

Hello my name is Glenn. I used Windows and Linux btw. Nice to meet you all.
As it happens, if you drilled a tunnel, straight down thru the earth to the opposite side, you would come out “within arms reach”! 
I live in Ottawa, Canada.
Hi, @GlennMandagi 
Welcome to the community!
I would encourage you to review the following discussions to help put a framework around your “adventure in Linux-land”!
As for asking questions, never hesitate!
The Community was conceived, from the outset, to be welcoming to all who seek knowledge and learn the skill-sets that are specific to the Linux world.
If you come discover that your window edge “grab-zone” is too small for your liking, the following is a full discussion around that topic and what the experts were recommending, for MATE.
welcome @GlennMandagi nice to meet you also.
Hi i’m Robert Elenbaas I live in Claremont CA. Thank you for letting me join all of you here.
I hope to learn and help here if I may.
Welcome @Robert-59 nice to meet you.
Thank you I hope to learn a lot from all of you.
Almost every week I learn something new here or a new or more efficient way of doing something. If you stick around I’m sure you will also. 
Hi
I’m a Finnish bus driver and I tried to install Arch Linux.
It didn’t work.
Hi, @Edith
Welcome to our community!
I am not an Arch Linux user, but the initial steps for Linux are essentially common.
Did you successfully download an “Live ISO image” for Arch Linux?
Did you successfully copy that onto a DVD or USB key?
Did you successfully tell you BIOS/UEFI to choose that device for boot priority?
Did the Live session come up with a GUI where you can open a Terminal session with access to the command line?
(This is critical, because success at this point tells us that the chosen distro’s Live environment can fully recognize your critical core hardware. If this step fails, then there is a need to use completely different strategies to analyze the problem.)
If so, please share with the Community the report of the following commands, so that they can fully understand your hardware context:
sudo inxi -Fxxx
sudo lspci
sudo lsusb
After studying those details, the Arch adepts will have a better understanding of how best to guide your next steps at troubleshooting and installation.
@Crabby Welcome aboard!
