    1) What is Archie?

    Archie is a program which lets you search for specific software programs and other files that are available via Anonymous FTP on The Internet. Archie is usually available on most Unix systems and on various and sundry other systems. In general, to use archie, you type ARCHIE filename where "filename" is the name of the thing you're looking for. For example, to find a source for the PKZip program, you can type ARCHIE PKZIP.

    To find out if your system has archie, you should speak with the person who runs your system. Also, try looking at the archie help files. If your system does not have an archie client (program) available on it, you can telnet to archie.ans.net. Login as archie and follow the instructions.


    2) What is telnet?

    Telnet is a program which allows you to log onto a remote computer from your local computer. The catch is that both of your computers must by on an ethernet style network such as The Internet and both must be running telnet software. If this is true, you can log onto one computer from another (assuming you have authorization to use both computers) even if the two computers are thousands of miles apart. To find out if your system has telnet access, ask your local system administrator. The general form of the telnet command is: TELNET hostname where "hostname" is the name of the remote computer you wish to use.


    3) What is FTP?

    The File Transfer Protocol (FTP) is used to transfer files from one computer to another connected over a network. For exmple, if you have an account on a machine and would like to get or put your file there, then you would type FTP hostname where "hostname" is the name of the host with which you wish to transfer files and at the password prompt, type in your password and then type "get file" to obtain a file and "put file" to transfer a file there. Typing ftp without the address of the machine would go into its command mode and have a "ftp>" prompt. To get help at that prompt type "?".

    Note that the ftp service is often used in conjunction with archie to locate and copy public domain software programs via The Internet. You will also see the term "anymous ftp" often. An anonymous ftp server is a system which lets anyone with Internet access to get files off it without having an account on that system. You just log in as userid anonymous and use your E-mail address as your password. Thousands of public domain software packages are available via anonymous ftp for just about any hardware platform in existence.


    4) What are USENET/BITNET/FREENET/FIDONET/UUNET?

    Usenet:

    Usenet (also known as Readnews) is a huge collection of electronic discussion groups. Usenet was born on the UUCP network, but its now most commonly used on The Internet. Usenet is also available via BITnet though its slower that way. What you do is to use a program called a Usenet interface to access these newsgroups. Some popular Usenet interface programs are tin and rn (Unix), nnr and netnews (IBM CMS), Anu-News (Vax VMS). What happens is that when you start any of these programs, you will be shown a menu of perhaps thousands of newsgroups. Each newsgroup covers a specific topic. To find out if you can use Usenet from your location, ask your system manager.

    Note that another collection of electronic discussion groups is called Listserv. Usenet and Listserv work very differently. For more information on Listserv refer to question 7 in this faq file.


    BITnet:

    BITnet (Because It's Time Network) is a service of CREN (Corporation for Research and Educational Networking) and consists of computers called nodes at many locations including major educational, research, and corporate institutions in all 50 states and 32 foreign countries. Using BITnet will enable one to communicate electronically with users at any of the other member institutions. Note that Bitnet is not Internet. They are two distinctly different networks, however, users on BITnet can communicate with users on The Internet.

    Freenet:

    Freenets are open-access, free, community computer systems. One such system is the Cleveland Freenet. sponsored by CWRU (Case Western Reserve University). Anyone and everyone is welcome to join and take part in the exciting project -...... There's no charge for the registration process and no charge to use the system. *** To register, telnet to any one of : freenet-in-a.cwru.edu freenet-in-b.cwru.edu freenet-In-c.cwru.edu

    FIDONET:

    An e-mail group of bbs operators. They operate somewhat like a usenet group with various echoes or conferences on different subjects. People call their local BBS with fidonet and leave messages. The local BBS relays these messages to the net so there is world-wide distribution. This is by phone-line and not instantaneous like an internet connection.

    Mail routing is normally done for 1 hour each day. Thus, it sometimes takes quite a while for messages to travel long distances. But, the system is pretty cheap, so many BBSes are starting to offer it. You may become a "point" off of your local fidonet BBS by just asking the sysop. When you're a point, you can receive mail directed to you personally (like having your own internet/bitnet address). Until then, you can just read the echoes, which are basically just discussion groups under Fidonet.

    To send mail from the Internet you need the Fidonet zone, area and node Check my signature file below notice that format for fidonet mail. If you want to mail to someone you need that number on the lesft which you then translate to the format on the right.........Good luck!

    * Fidonet: 1:273/203 Joe.Johnston@f203.n273.z1.fidonet.org *

    For anyone interested in FidoNet, there is a whole subdirectory called FIDO in the MSDOS directory on SIMTEL20, containing extensive information, including explanation of FidoNet, guide for its nodes, latest Fido BBS, and gateways between FidoNet and Internet (Text files), in addition to programs and utilities (Binary files).

    To get these files, either FTP to WSMR-SIMTEL20.Army.Mil (192.88.110.20) or send e-mail (with no subject) directly to:

    BITNET: LISTSERV@NDSUVM1 or LISTSERV@RPIECS Internet: LISTSERV@VM1.NODAK.EDU or LISTSERV@VM.ECS.RPI.EDU

    In the body of the mail message write the command:

    /PDGET format PD:filename.filetype encoding where: format is MAIL, NETDATA, BITSEND, or PUNCH. encoding is ASIS, TRANSLATE, UUENCODE, OLDUUE, or XXENCODE. filename.filetype is the name and extension of the file to get.


    UUNET:

    UUNET is basically the collection of hosts which connect the internet via modem connections and UUCP software. Its a poor mans internet. Often Usenet news is transferred to some sites via UUCP.

    5) What are *.tar files and what can we do with them ?

    *.tar files are tape archive files that are in an archived format to be stored on tape or some other medium. They allow one to store may files, directories and subdirectories in just one file. Usually they are compressed *.tar.Z and one has to first uncompress (using %uncompress ) them and then

    prompt% tar -xvf name.tar

    to extract the files from the tar file. The option x is for extraction, v is for verbose and f is for file name (rather than a tape device). If you need more detailed information do a man tar.

    Note that other types of files are briefly explained in question 15.


    6) What about private computer services?

    Compuserve:

    To send an E-mail message to someone who has a Compuserve account from the internet, you should just type mail account_number@compuserve.com at the prompt. For example, if you know that the account # is 12345,6789 then

    there address would be 12345.6789@compuserve.com.

    would do. Note that on The Internet, the comma in Compuserve addresses must be replaced with a period. To access Compuserve through the internet, telnet to hermes.merit.edu and type Compuserve at the prompt. There is a fee for this internet access which gets added to your Compuserve bill.

    MCIMAIL:

    MCIMail is a private service which allows you to receive and send mail via The Internet. For info about MCIMail, call 1-800-444-6245. To send an E-mail message to someone on MCIMail use userid@mcimail.com where "userid" is the name of the recipient's MCIMail account. Send E-mail to postmaster@mcimail.com if you need to find out the name of someone there.

    Prodigy:

    Prodigy is the name of another private service, which amongst other things, lets you exchange mail with Internet users. To send E-mail to a Prodigy user, use the address form of userid@prodigy.com.

    America On-Line

    Is yet another popular private service. Like the ones mentioned above, it has lots of stuff of interest to many people, including the ability to send and receive mail via The Internet. To send someone on America On-Line an E-mail message, use the form of the address as userid@aol.com

    Note to people who are thinking of participating in one of these services. Many computer stores sell kits for starting accounts on these services. The kits often cost around $30 US or so. Quite often, if you're resourceful, you can avoid these startup kit prices and still get on the service of your choice. The trick is to realize that many modems come with free startup kits for most of these services. They're the same ones you pay for separately in the stores. If you know someone who has just bought a modem, ask that person for his or her start up kit if the person's not going to use it. Also, most of these services will send you a free kit of you respond to one of their advertisements which appear in most of the popular computer magazines available at many bookstores.


    7) What is Listserv?

    Basically speaking, Listserv is a network of electronic discussion groups. These groups are called "lists" because whenever someone who participates in a particular discussion sends an E- mail message to the group, that message is then distributed via E-mail to the "list" of subscribers.

    Almost anyone can access Listserv lists. Some lists, due to nature of the topics that they cover, are restricted access, and a prospective subscriber must apply for access. Listservs are handled via the BITnet links. Internet users can access Listservs via various gateways.

    There are a number of commands you can send to Listserv which will give you information about Listservs. To review Listserv commands send E-mail to listserv@vm.temple.edu or to listserv@templevm. In the body of your mail type:

    GET LISTSERV REFCARD

    Listserv will send you a reference card of its commands. Pay particular attention to the LIST command which is how you get information about lists.

    Note that listserv@vm.temple.edu and listserv@templevm are the same computer. The computer at Temple which runs Listserv happens to be on both the BITnet and Internet networks. As a result, each account on this system has two addresses.

    Listserv@vm.temple.edu is Temple's Internet address for Listserv.

    Listserv@templevm is Temple's BITnet address for the same Listserv.

    Note that most Listservs are alike so you can send the same commands to any Listserver, not just Temple's.

    You can obtain a list of the Help-Net available archive files by sending an "INDEX HELP-NET" command to LISTSERV@TEMPLEVM. These files can then be retrieved by means of a "GET HELP-NET filetype" command, or using the database search facilities of Listserv. Send an "INFO DATABASE" command for more information on the latter.

    More information on LIstserv's commands is available in the "General Introduction Guide", which you can retrieve by sending an "INFO GENINTRO" command to LISTSERV@TEMPLEVM or LISTSERV@VM.TEMPLE.EDU.


    8) How can I find someone's e-mail address?

    If the person has ever sent mail to a Usenet group, you can try the following: Send mail To: mail-server@rtfm.mit.edu and the following one line in the BODY of the note.

    send usenet-addresses/

    where name is the name of the person you are looking for. The name can be a full name, first and last name, or last name only.

    You can also search the Newsgroups on-line for a name via DejaNews
    http://www.dejanews.com/

    You can also try the Internet Address finder:
    http://www.iaf.net/
    (option to include yourself)

    Try OKRA the net.citizen Directory Help Service
    http://okra.ucr.edu/okra/
    (option to include yourself)

    Look into InfoSeek's E-Mail Address's option
    http://www2.infoseek.com/

    Try the WhoWhere? PeopleSearch
    http://www.whowhere.com/

    Try Four11 at http://www.Four11.com
    Four11 White Page Directory
    (includes the old LookuUP! Directory)
    (option to include yourself)

    Try Masha Boitchouk's finding an e-mail address page
    http://sunsite.oit.unc.edu/~masha/
    (Great!!! links to other search methods - especially colleges)

    You can try a whois server.
    Send mail To: mailserv@internic.net Subject: whois <name> where "name" is the person you are looking for.
    The name can be a full name, first and last name, or last name only.

    This will return a listing of all people with that name and their e-mail address. To find out how the whois server works you can send mail to the same address but with the following lines in the body of the note.

    /help /end

    Another Whois server: send e-mail To: whois@infomania.com. Subject <your friends name>

    leave the message area blank

    and another Whois server: send e-mail to mailserv@ds.internic.net, leave subj. blank and in the message body type: whois "your friend's name".

    You can also telnet to the main Whois server:
    Telnet to ds.internic.net, At the promt, Type whois "your friend's name"

    Also try Yahoo's reference to white pages http://www.yahoo.com/Reference/White_Pages/

    You also can send an E-mail to listserv@vm.temple.edu, and the following one line in the BODY of the note. GET FINDING PEOPLE F=MAIL

    If all these methods fail, you can also try the White pages of telephone books to search for their home or business address.

    Try the Switchboard at http://www.switchboard.com/ the nationwide residential and business directory

    Use Netscape... under its Directory menu is the Internet White Pages, and within that is 4 different search engines.

    Last but not least, if you wish to pay (ugh??):
    You can try Find A Friend
    http://www.ais.net/findafriend/

    Thanx to Gerald E. Boyd gboyd@netcom.com


    9) What are gif files and how can I view them?

    GIF stands for Graphic Interchange Format. Compuserve developed this format for graphics files so that its many clients with all sorts of different computers can look at various pictures. Gif is a way to store files in a binary format that can be read on most of today's computers. In order to view these pictures, you can either get a gif viewing utility for pc's or view them using xv,xgif,xloadimage on X-stations. Some word processing programs and desk top publishing programs can also open GIF files. Many Gopher servers store gif files. Pictures of NASA space shots, weather maps, people, places, etc. are available via Gopher as well as anonymous ftp from many sources. When you transfer gif files via ftp or Kermit or whatever, you must treat them as binary files. In addition, there are some other propular graphics file formats such as JPEG and PICT. Each requires a specific program to read them, but these are usually in the public domain.

    10) How can you add "signatures" to your mail?

    If you are using elm mailer on unix systems, then all you have to is put your signature in a .signature file using a text editor and your .elmrc file so that the parameters "localsignature" and remote "signature" are set to the right files.

    To add a signature automatically to outgoing mail in CMS, use the mail feature. When you type mail, you will get into a screen which has the options menu on the title bar. In the "Options" menu, choose "send" and then "settings" and change the "Signature?" option to "automatic", and the "Signature File" option to the name of your signature file.


    11) What are gopher, irc ?

    IRC is an full-screen interface to the internet relay chat system. It lets people talk to others around the world who are on the internet through specialized interest groups.

    Gopher is a distributed document delivery service. It works via The Internet. If you have only BITnet, you can't use Gopher. It allows a neophyte user to access various types of data residing on multiple hosts in a seamless fashion. This is accomplished by presenting the user a hierarchical arrangement of documents and by using a client-server communications model. The Internet Gopher Server accepts simple queries, and responds by sending the client a document. Gophers frequently include such services as archive ftp searches, on-line books through project gutenberg, News and Phone directories of many universities as well as pictures, public domain software, current weather conditions and hordes of other stuff.

    Extention - Utility for uncompression -
    .zip Requires PKUnzip
    .arj Requires ARJ
    .lha Requires LHArc
    .Z Requires UNIX uncompress
    .tar Requires TAR
    .hqx Binary -> Hexadecimal text converted file. Requires BINHEX or Stuffit to convert back to binary
    .sit Requires Stuffit
    .cpt Requires Stuffit or Compact Pro
    .sea Self-extracting (Self Extracting Archive)
    .bqs Compressed BASIC language program. Requires Unsqueeze.
    .gz Requires GNU gunzip
    .taz Requires UNIX uncompress then gunzip
    .zoo Requires Zoo

    14) Finding job sources via The Internet.

    There are several Usenet newsgroups where jobs are both advertised and where job seekers can post resumes. These groups are mostly found in the miscellaneous hierarchy. A few other hierarchies might have jobs groups too. As far as I know, there are no Listserv groups of this nature. If I am wrong, please let me know.

    For jobs in Higher Education, probably the best source is the Chronical of Higher Education. These folks have a Gopher server too. Its in the USA list and its well worth looking at.

    15) How can I read Usenet via E-mail?

    Usenet can be read at http://WWW.Reference.COM/ or using their e-mail service. To use the service by e-mail, you'll need to send request messages to email-queries@Reference.com. Commands (search, output formatting, etc.) are placed in the body of the mail message, followed by an optional END used to prevent the processing of signatures. The subject field of the message is ignored. Each message is a request to the service. Each request consists of a number of commands. Each command must start with a new line with no leading spaces. Continuation lines begin with a space or a tab. All commands are case-insensitive. Unless otherwise specified, requests are associated with the return address of the user message. Service replies and deliveries will be sent to that address. More info can be obtained by sending the message "help" to the queries address listed above.


    How can I post to Usenet via e-mail?

    To post to, say, alt.tv.animaniacs, replace the periods with hyphens and send to that @cs.utexas.edu So it would look like
    alt-tv-animaniacs@cs.utexas.edu
    The UTexas service is just that, a service, and it's not as reliable as if you had your own poster. It may take a little longer to get to the list and occasionally they do go down, but as a whole it's a pretty good service. Please only use it if you have no other recourse.
