Developing networking experience?

Wed May 4 20:46:16 MDT 2022

Thank you, Bob, for the reply and suggestions.

I did kinda resign and offered that that person cultivate their inner hoarder, and start collecting equipment they can patch and make them talk to each other, whether that equipment comes from CSU Surplus, Craigslist, FB Marketplace, hand-me-downs from friends and family, etc.

I agree Pis would be a great fit. Tying them together with a WiFi home router, or an inexpensive consumer-grade 5-port ethernet switch (or even both?) would be a good way of learning networking. The issue wasn't the software; it was just getting hands-on with actual hardware.

Thank you also for the invite to the group. I'll be sure to pass it along.

Hello Curtis,

Apparently no one had any ideas.  :-(  Let me add something.

Fun stuff!

I am unaware of most of the groups in the area that would be most
related to real world networking.  There are several groups that do
what I might call "social networking" which are good for that
purpose.  But there just are not that many hard core technical
groups.

On the bad news side we are not that densely urban that every topic is
well covered.  On the good news side we are not that densely urban.

I don't even know what classes are available in this area. :-(

Obviously the best way to learn is by a combination of academic
studying and practical hands on doing.  For someone interested in
networking they would be hard to go wrong with "The TCP/IP Guide by
Charles M. Kozierok No Starch Press 2005".  Or any of the many other
fine tomes of wisdom that are available.

For practical hands on one needs to "do".  I'll suggest putting
together a Raspberry Pi WiFi Access Point.  It's a useful project in
and of itself.  Doing so will cover many of the parts of networking.
It doesn't even need to be a Raspberry Pi as one can use a laptop or a
desktop.  Almost any old cast off obsolete computer is perfect!
Install an OS of which many are suitable such as Debian, Ubuntu, Void,
Fedora, Alma, FreeBSD, and the list goes on.  Though perhaps Ubuntu
would be the most popular for this task and would have the most help
from the web articles for doing so.

Then install and configure all of the software components.  WPA
Supplicant software for the WiFi connection.  A DHCP client for the
system itself.  A DHCP server for the WiFi LAN being created.  I use
"hostapd" a free software WiFi driver for the Access Point.  Then
Linux netfilter iptables rules to route and set up NAT for the LAN.

It's a good exercise to learn a lot of parts.  It is useful to have
that kit available for other network projects.  It is only the tip of
the iceberg though and there is always more to learn.

And then at NCLUG we love it when people show-n-tell their projects.
See one.  Do one.  Teach one!  Put together something fun.  Come and
show it off to the group!  Also come and see other people's projects
and get inspired to do something! :-)

Bob
