- I keep a directory of Internet sites accepting anonymous FTP and mail
- retrieval of their files. Two listings are posted to the Usenet, as a
- 3-part article, on a monthly basis. You can find them in the following:
-

- news.answers comp.misc
-
-
- Topics are shown below and with their respective answers.
- Format: (#Q) for a question and (#A) for the answer.

- (12) What is and how do I use the FTP program?
- *This is going to updated in the future to include more info*
-
-
-
- (1Q) What types of lists are available?
-
- (1A) Lists available and what is included in them:
-
- SITES - contains comphrensive information
-
- o Site name o Date of last audit (ISO format)
- o IP address(s) o UT/GMT difference
- o Comments/problems address o Country (ISO format)
- o Organization o Types of files
- o E-mail server if available o Restrictions
-
- FILES - useable with the Grep utility for file searches
-
- o Site name o Date of last audit (ISO format)
- o IP address(s) o UT/GMT difference
- o Types of files o Country (ISO format)
-
-
- (2Q) How do I read the ISO date?
-
- (2A) The format is Year/Month/Day (1991/12/30 is 30 December 1991) and
- a leading zero is required if the month or day is a single digit.
-
-
- (3Q) Retrieving the list from alternate sources.
-
- (3A) I will mail copies to individuals without other means of retreival
- or to admins of closed systems. Leave me mail for help.
-
- It is available from various FTP sites which archive the Usenet
- news.answers group in the directory 'ftp-list'. Also look for 'ftp-list'
- in either the Sites or Files list. Use anonymous FTP to get it from its
- home site:
-
- ftp.netcom.com 192.100.81.10 /pub/profile/ftp-list
-
- These sites mirror or conatin all or some of the lists maintained at
- ftp.netcom.com.
-
- North America - ftp.uwp.edu 131.210.1.4 in /pub/ftp.list/ftp-list
- Europe - nic.switch.ch 130.59.1.40 in /mirror/ftp-list
- Europe - ftp.denet.dk 129.142.6.74 in /pub/misc/ftp-list
- Europe - garbo.uwasa.fi 128.214.87.1
-
-
- (4Q) Retrieving the raw databse.
-
- (4A) Yes, the database is available for importing into your own database
- programs or anything else you want to do with it. It uses the vertical
- bar as a field seperator, as the character is not used in any fields.
- A Perl search and formatting utility is coming soon. The raw database
- only available on the home FTP archive and ftp.uwp.edu.
-
-
- (5Q) Using FTP without direct Internet access.
-
- (5A) It is possible to get files from a site by using a general mail
- server or many sites have their own servers. If you're on BITNET, ask
- your sysadmin or technical support group about PUCC. For non-BITNET
- sites, try using DEC's; you will find instructions for using it below,
- in (10A).
-
- NOTE: Please make sure your system admin has approved the the use of
- a mail server, as files can take system resources of not only
- your site, but several sites down the stream.
-
-
- (6Q) Problems with a site.
-
- (6A) Mail the problems to the address shown in the Sites list. If a FTP
- comments address is not shown, attempt to use 'ftp@site_name'; replace
- 'site_name' with the name of the troublesome site. If that fails, post
- a note to comp.archives.admin (the newsgroup for archive administrators).
-
-
- (7Q) Information is wrong or outdated.
-
- (7A) Send mail to me detailing the incorrect information and the
- corrections. If you are the site manager for the archive, please see
- below (8A) for the information I need.
-
-
- (8Q) Getting a site listed or changes made.
-
- (8A) Send the following information to aftp-list@netcom.com.
-
- o Site name (and aliases you wanted listed).
- o IP address.
- o Manager(s) full name & email address(es).
- o Address for FTP related issues (problems, comments, etc...).
- o General description of the types of files available.
- o Directories that are for anonymous FTP use (besides /pub).
- o Site's location (country).
- o Organization operating site.
- o UT/GMT difference (include daylight savings time).
- o Are there any special restrictions?
- o Can it be used 24 hours/day?
- o Is an E-mail server available for the site's files only?
-
-
-
- (9Q) Making the list publicly available.
-
- (9A) Please let me know if there is a site that archives either the Sites
- or Files list. I will include it in future updates; the more people who
- have access, the better. Please keep the list updated.
-
-
- (10Q) Using the general mail server at DEC's Western Research Labs.
-
- (10A) Send mail to ftpmail@decwrl.dec.com with 'help' in the body of the
- letter. You CANNOT send a blank letter, commands are not optional.
-
-
- (11Q) What is Archie and how does it relate to the list?
-
- (11A) Archie is a special server that keeps file listings from different
- FTP sites. You can Telnet to a server or use a client program to search
- for specific files.
-
- Here are some sites; send mail to 'archie@site_name' for a help file.
-
- archie.ans.net (North America)
- archie.sura.net (North America)
- archie.unl.edu (North America)
- archie.funet.fi (Finland/Mainland Europe)
- archie.au (Australia/New Zealand)
- archie.doc.ic.ac.uk (Great Britain/Ireland)
- archie.ncu.edu.tw (Taiwan)
- archie.cs.huji.ac.il (Israel)
- [ The above site only accepts client (Prospero) requests. ]
-
-
- (12Q) What is and how do I use the FTP program?
-
- (12A) For novices to the Internet, I highly recommend a recent book,
- 'The Whole Internet User's Guide and Catalog' by Ed Krol. It is wriiten
- clearly and contains an enormous amount of information. Read it cover to
- cover, and keep it close at hand. Published by O'Reilly & Asscociates, it
- is available from many computer bookstores or O'Reilly's worldwide
- distributors. Contact the publisher at +1 707-829-0515.
-
-
- The information below was originally maintained by John Granrose (the
- old maintainer of the listings). Mike Jones added the info about the
- existence and location of the compression data chart maintained by David
- Lemson. I added some, too little to be thanked or hated for its content.

-
- This is not a definitive guide to FTP, but will give a novice a
- general idea of what it is and how to do it.
-
-
- What is FTP?
-
- FTP (File Transfer Protocol) allows a person to transfer files
- between two computers, generally connected via the Internet. If
- your system has FTP and is connected to the Internet, you can
- access very large amounts of archives available on a number of
- systems. If you are on Bitnet or a UUCP host, you should look for
- servers that work through the mail. A good source of information
- on archives in general, is the Usenet newsgroup comp.archives.
-
-
- What is Anonymous FTP?
-
- Many systems throughout the Internet offer files through anonymous
- FTP. These include software, documents of various sorts, and files
- for configuring networks. Archives for electronic mailing lists are
- often stored on and available through anonymous FTP. Note that all
- this is subject to change.
-
-
- Commands
-
- All the normal FTP commands may be used to retrieve files. Some FTP
- commands are the same on different computers, but others are not.
- Usually, FTP will list the commands if you type 'help' or type a
- question mark (?). Also, your computer's help command may have
- information about FTP. Try 'man ftp' or 'man ftpd'.
-
- Some useful commands available on most systems include:
-
- get copy a file from the remote computer to yours
- ls/dir list the files in the current directory
- cd Change directory
- binary Switch to binary mode. For transferring binary files
- ascii Switch to ascii mode. Ascii mode is the default mode
-
-
- Procedure
-
- Anonymous FTP is a facility offered by many machines on the Internet.
- This permits you to log in with the user name 'anonymous' or the
- user name 'ftp'. When prompted for a password, type your e-mail
- address -- it's not necessary, but it's a courtesy for those sites
- that like to know who is making use of their facility. Be courteous.
-
- You can then look around and retrieve files. (Most anonymous ftp
- sites do not permit people to store files)
-
- Typically, a directory called 'pub' is where the interesting things
- are stored. Some sites will have a file with a name like ls-lR,
- that contains a complete list of the files on that site. Otherwise,
- you can type ls -lR and get such a listing -- for some sites, this
- can take a LONG time.
-
- Usually, files are grouped in archive files, so you don't have to
- get many small files separately. The most common archival file format
- for the Internet is tar. Occasionally, people use shell archives
- (shar) instead. Tar archives can be unpacked by running the 'tar'
- command -- you may want to first do a 'tar t' on the file to see what
- it contains before unpacking it. Be careful when unpacking shell
- archives since they have to be run through the Bourne shell to unpack
- them. (The simplest way is to use the unshar command)
-
- Files are often stored compressed -- for Unix, the most common scheme
- is the compress program, indicated by a .Z suffix on the file name.
- Sometimes, people use programs like Arc or Zoo, which are combined
- archival and compression formats. (There are probably other archival
- formats as well - talk to the systems staff if you encounter them and
- don't know how to deal with them)
-
- When retrieving non-text files, you must use binary mode, otherwise
- the file gets messed up. To do this, use the 'binary' command. (It's
- safe to set this for text files. If the site at the other end is
- non-Unix, you may need to use some other mode -- see the documents
- for that site and for FTP)
-
- The simplest way to initiate FTP would be to give the command 'ftp
- <system-name>'. The <system-name> is the remote system you are
- connecting to, either a name (wsmr-simtel20.army.mil, if you have
- an entry in /etc/hosts or are accessing a Domain Name Server) or
- the Internet address (192.88.110.20 for Simtel20). After a short
- wait, you will be prompted for your username. If you do not have
- an account on the remote system, some systems allow you to use
- 'anonymous'. This gives you a restricted access path.
-
- You would then be prompted for a password. Some systems will tell
- you to send your real identity as the password. What you type doesn't
- matter, but it is suggested to give your mail address. Other systems
- need a password of 'guest', or something similar.
-
- After that, you should receive the FTP prompt ( usually ftp> ) and
- have access. You can get a directory of files be giving a 'dir'
- command or if the remote system is Unix-based, 'ls -l' will give
- the familiar output. On Simtel20, there is a file available in the
- default anonymous ftp directory that explains what Simtel20 is and
- where files are located. The name is 'SIMTEL-ARCHIVES.INFO.nn, where
- ".nn" is a file generation number. You don't need to specify the file
- generation number when requesting the file. In fact, it's better not
- to because you will always get the latest generation that way.
-
- Unix systems will all have the familiar directory structure, and
- moving around is done with the familiar 'cd' or 'cwd' command.
- TOPS-20 systems have a different structure, but movement is still
- accomplished with the 'cd' command.
-
- Different systems have different organizations for their files, and
- the above example is the way most archives have it set up. By looking
- around other systems, you can learn how their files are arranged and
- move around much faster. Note, however, that FTP will not allow you
- outside the FTP 'root' directory. Moving about the entire system is
- not permitted.
-
- These are the common Unix file types:
-
- SUFFIX FTP TYPE
- ------ --------
- .Z bin compress
- .arc bin ARChive
- .shar ascii SHell ARchive
- .tar bin Tape ARchive
- .uu ascii uuencode/uudecode
- .zip bin Zip
- .zoo bin Zoo
-
-
- To get a list of all file compression/archiving methods and the
- programs to uncompress/unarchive (on the PC, Mac, Unix, VM/CMS,
- AtariST and Amiga systems), FTP to the following sites and
- retrieve the listed file:
-
- ftp.cso.uiuc.edu /doc/pcnet/compression
- gator.netcom.com /pub/profile/compression.Z
- nic.switch.ch /mirror/ftp-list/compression.Z
- (make sure to set the binary mode with 'bin')
-
- This could be helpful to people new to FTP that don't know how
- to unpackage the file they have just transferred.
