BASE: File Permissions
by Stan Reichardt <https://www.sluug.org/bio/Stan_Reichardt.shtml>
A file is not merely its contents, a name, and a file type. A file also has an owner (a
user ID), a group (a group ID), permissions (what the owner can do with the file, what
people in the group can do, and what everyone else can do), various timestamps, and other
information.
Each file has a set of "file mode bits" that control the kinds of access that
users have to that file. They can be represented either in symbolic form or as an octal
number.

As part of this talk, he will step by step show creating your own "no-charge” (i.e.
free) container in the cloud.
How to get those containers networking to each other. It used to be simple. You went
to AWS. Created a new node. Maybe added some disk to it. And off you went, computing
happily ever after.
Too simple. Catch: Everyone's nodes were in one subnet. We could all see one
another. Maybe your neighbor wasn't pretty. Maybe they'd been cracked.
Whatever reason, you want privacy. Private is no longer simple. No more 'just create
a node'. Creation starts with a "Virtual Private Cloud". Then you get to
create subnets, security rules, IP gateways, NAT Gateways in multiple availability zones
in multiple regions... Got that?
We'll get into the AWS Nomenclature. AWS services are provided in
"Regions": "us-east", "us-west", "canada"...
Regions have "Availability Zones".
Designed to fail separately.
Redundancy uses multiple zones within a region. EC2 and subnets make heavy use of zones.
We'll get into...
Public and private subnets.
Gateways ("public").
NAT gateways ("private").
Security rules.

Annual balloting is done this month. Ballots and security envelopes will be available.
Also, a very short annual meeting will be held, as required by our by-laws.
NOTE: As of the time this message is being sent out, our SLUUG google calendar of
meetings in the STL Metro Area seems to be down.
