Goals
In this session you will:
- Use telnet to read mail and do other amusing things
- Use FTP to move files to a remote server
- Use an IRC server
- Read and post USEnet messages around the world
telnet
- use the built-in telnet client.
Start -> Run telnet [hostname]
- you will "land" in your home directory (~)
- common commands
ls lists files in the directory (like "dir")
pwd shows the present working directory
cd change directory (like "cd")
mv move/rename file (like "move" and "ren")
cp copy file (like "copy")
rm remove file (like "del")
chmod change permissions

- setting up your webspace
USEnet
Usenet (aka "news", "newsgroups") is a global equivalent of your work
or church "bulletin board". You post messages (which look suspiciously
like email) and they are distribute around the world. It can be messy and,
like the rest of the net, content is not regulated.
The most interesting and useful thing about newsgroups is that they're grouped
by topic or subject matter. So if you like cats you might read:
news:rec.pets.cats.misc.
Accessing the news
- web-based news like www.dejanews.com
- client/server model
- download a client
- you will need a news server like lace.colorado.edu or whatever your ISP tells
you
- get a list of groups
- "subscribe" to some
- read
- post a new message or followup a post to boulder.test
FTP
File Transfer Protocol is (judged by bandwidth) the most common Internet
service.
There are two main ways to use FTP:
- anonymous ftp: logging in anonymously to get
publicly-available files (e.g., software downloads)
- login as a user: logging in with a username/password
to work with your own files (no one can get there without a user/pass)
Using the FTP client
- download and set up a client, or use the built-in client.
Start ->
Run -> ftp [hostname]
- you need a hostname, user, and pass from your isp
- log in and navigate (anonymously, then as a user landing in your home
directory ~)
- Make a directory called "public_html" (or other name as specified by your
webmaster)
- cd to the new dir, and upload your file

IRC
Internet Relay Chat is what many think of when they imagine the Net: people
doing real-time chat at their keyboards.
