Hi. I need to learn about networks to make myself
more attractive to employers.
Therefore, I have decided to install a simple network in my
home, consisting of a unix system running sco unix v3.2.4, tcp-ip
nfs and ethernet, and 2 dos systems running pc-nfs.
The question is:
is this a good way to get hands on experience with networking?
if so, is this a reasonable network to learn on?
Where do I get pc-nfs and tcp-ip for dos?
What do i need in the way of hardware, boards, cables, tee's, and 
terminators?
what is a good supplier of the necessary hardware?

I have done sys admin for 6 years, but the company where i worked didn't
have any networks. it was on an amdahl running uts.
I am currently unemployed and all companies i have contacted, seem to want
network experience.
thanks for any help.
Phil
