- MAP02: LISTSERV FILE SERVER COMMANDS
- ------------------------------------
-
- "Patience is a necessary ingredient of genius"
- -- Benjamin Disraeli
-
-
- Remember when you subscribed to the Roadmap list? You sent an e-mail
- letter to LISTSERV@UA1VM.UA.EDU which said
-
- SUBSCRIBE ROADMAP YOURFIRSTNAME YOURLASTNAME
-
- in the body of your letter. Well, the SUBSCRIBE command
-
- SUBSCRIBE listname < full name >
-
- is just one of dozens of LISTSERV commands that you can use by sending
- an e-mail letter to LISTSERV@UA1VM.UA.EDU (or to any other LISTSERV
- address) with a command in the body of your letter!
-
- First off, what is a LISTSERV? Well, a LISTSERV is a mailing list
- program designed to copy and distribute electronic mail to everyone
- subscribed to a particular mailing list. We will talk much more about
- LISTSERVs and LISTSERV commands next week, but LISTSERVs work on
- a concept called "mail explosion." A single piece of e-mail is
- sent to a central address (the LISTSERV's address), and the
- LISTSERV then "explodes" the letter by duplicating that single
- letter and sending one copy of that letter to every single person
- subscribed to a particular mailing list (1). This "mail explosion"
- concept is what allows me to communicate with all of you with
- just a single e-mail letter sent to a central address.
-
- What we are going to talk about today, however, is the LISTSERV file
- server. In an effort to keep this group's mail volume to a minimum,
- I've placed many of the "optional" workshop files on the University of
- Alabama's LISTSERV file server.
-
- What is a LISTSERV file server? Well, besides distributing letters,
- LISTSERVs can also serve as a "library" of files -- files that YOU
- can retrieve using nothing but a simple e-mail letter sent to the
- LISTSERV's address with a few simple commands in the body of that
- letter.
-
- When you subscribed to the Roadmap list, you mailed an e-mail letter
- to LISTSERV@UA1VM.UA.EDU with this command in the body of your letter:
-
- SUBSCRIBE list-name < full name >
-
- To get files from the University of Alabama's LISTSERV file
- server, you are going to send another letter to LISTSERV@UA1VM.UA.EDU
- with a NEW command in the body of your letter:
-
- GET filename filetype F=format
-
- Now that may look a little intimidating, but you are about to see that
- the GET command is as easy to use as the SUBSCRIBE command. Let's break
- the GET command down into its individual parts:
-
- GET tells the LISTSERV that you want it to send
- a file to you.
-
- filename filetype tells the LISTSERV the name of the file that
- want it to get (for example: COPY NOTICE,
- ROADMAP 94-00001, RFC 1462, etc.).
-
- F=format tells the LISTSERV how you want the file sent
- to you. For what we are doing, lets use
- F=MAIL (that way the LISTSERV will e-mail
- the files to you).
-
- Now suppose I tell you that there is a file on the LISTSERV file server
- at the University of Alabama called COPY NOTICE. What do you have to
- do to retrieve this file? Well ...
-
- 1) Address an e-mail letter to LISTSERV@UA1VM.UA.EDU (remember,
- you are about to send a command, and all commands must be
- sent to the LISTSERV address).
-
- 2) In the body of your letter type GET COPY NOTICE F=MAIL
-
- How about if I told you there was a file on the LISTSERV file server
- at the University of Alabama called RFC 1462? Well, again you would
- send an e-mail letter to LISTSERV@UA1VM.UA.EDU, but this time the
- body of the letter would say GET RFC 1462 F=MAIL
-
- Think you can handle this? I hope so ... because this is your first
- homework assignment (eeeeek!). There are three files on the LISTSERV
- file server at the University of Alabama (LISTSERV@UA1VM.UA.EDU).
- Those files are:
-
- filename filetype description
-
- COPY NOTICE The Copyright notice for the entire
- Roadmap workshop, along with the
- workshop's acknowledgments.
-
- NET INTRO My own special explanation of what
- the Internet is and how it works
-
- RFC 1462 The OFFICIAL "What is the Internet"
- RFC/FYI by Krol and Hoffman (this is
- kind of advanced stuff).
-
- What I want you to do is use the GET command to get at least one of these
- files (you can get more than one if you want). What do I want you to do
- with the file after you get it? READ IT!! (As I said yesterday, PLEASE do
- not send the files back to me -- my mailer can not handle the volume
- of your responses).
-
- That's your homework. Have a GREAT weekend!!
-
- IMPORTANT NOTE: You must write a *NEW* letter to LISTSERV@UA1VM.UA.EDU
- for your GET commands to work. Replying to this letter will *NOT*
- work!
-
- -----
-
- What if the GET doesn't work? First, realize that it may take several
- hours for the LISTSERV to process your request and send the file
- back to you (hence the "patience" quote at the opening of today's
- lesson). 25,000 requests, even at one second per request, is going
- to take a LONG time to process!
-
- If, after an incredible amount of time has passed, you have not
- heard back from the LISTSERV, double check that you used the
- correct address: LISTSERV@UA1VM.UA.EDU (thats "you-ay-won-vee-em").
- Second, make sure the GET command is in the BODY of your letter.
- Finally, make sure that you have included all of the parts of the
- GET command (GET filename filetype f=format).
-
- If, after all of this, the command still does not work, talk with your
- local Internet service provider (do NOT write to me). Chances are, the
- problem is that your mail program is putting the wrong return address
- onto your letters. This is a local problem, and your local Internet
- service provider should be able to give you some suggestions.
- (Again, do NOT write to me!)
-
- Have fun :)
