it can be viewed from an internet-connected browser anywhere. You
are responsible for awareness of the information posted here.
with approximate weekly topic coverage corresponded to related
readings, homework assignments, and in-class slides I will use.
Please follow this outline as we move through the topics, for assignments and reading
I want to assign.
1) read all the announcements below and follow all the
links they contain. I will expect you to be familiar with the
information they convey.
2) do the reading and homework shown in the "Reading" and
"Homework" columns of the course outline's topic #1.
A virtual machine (VM) for you
- hands-on lab exercises will be performed on a virtual machine that
you can run in your own computer.
and installing your VM

in and out of it if necessary (accompanying howto

account is available for your use.
Using ssh (secure shell). ssh is an important tool you will use
for interacting with remote computers. For that you will need an ssh
client. There are a number of ssh
Distributing files from sputnik to the class as a whole,
publicly - the above file transfer discussion describes file movement
to and from your own home directory, exclusive to you. Sometimes I will
want to have someplace to put a file so everybody can get to it and
download it. When I do that, here's
how to download them.

What is it??
asks the switchboard operator. The switchboard is a board. It's for
switching. Switching changes a circuit between you and somebody. It can
complete a circuit to your Aunt Bheulah in Iowa City so you can
thank her for the knit socks. After you hang up if you want to call
your uncle in Waco you'll need to switch circuits, to get a circuit
to him instead of her. That's what the operator does for you. The
"switch"ing in "switch"board is circuit
switching. Nowadays in computer networks it's not circuit switching
anymore, it's packet switching.
Functional layering - the famous "Open Systems
Interconnect" model is depicted below. Somebody once had the
idea that maybe there could be a way to get independent computer
systems of different types to be able to exchange information with
one another. The diagram blueprints the idea for "how in the
world are we going to make that work??" That idea is the
subject of this course.
First-day administrative information you will
need to know:
Running linux at home.
Slides available online - for
most if not all slides I will show in class. Links to them can be
found in the "Slides" column of the course outline.
Course-long textbook reading -
a chapter-by-chapter list ( 6th edition,
5th edition ). The textbook is divided into chapters and they in turn into numbered
sections. The list tells you which sections to read for this
course when chapters are assigned. For example if I assigned chapter
10 and it had 17 sections, if this list specifies "10.1-100.5,
10.7, 10.12-17" it means I didn't feel sections 10.6 nor
10.8-11 were relevant enough so I only list the balance of the
chapter. Read unlisted portions for your own interest if you wish,
but the listed sections are what's officially assigned to you.

Wireshark - is an excellent free packet capture utility.
What is a packet, and why caputre it? We'll talk about that later. I
will ask you to install and use Wireshark later in the semester,
assuming you have a linux or windows computer available on which to
do so. Please visit Wireshark's
