Gopher, FTP, and TELNET, but cannot supply <strong>resources</strong> through these protocols to<br />

people outside the company.<br />

FTP (File Transfer Protocol)<br />

A program for sending and receiving files to and from a remote computer to your local<br />

host. Lets you connect to many remote computers, as an anonymous or guest user, to<br />

transfer files back to your computer. Lets you list file directories on foreign systems, get<br />

or retrieve files. You cannot browse menus, send email, or search databases using FTP.<br />

<strong>The</strong> easiest is to use ftp with a Web browser like Netscape. Just feed the browser<br />

the file's location, in a format like this ftp://ftp.eunet.no/pub/text/online.txt.Z. <strong>The</strong> codes<br />

after the "//" show first the host name, then the directory, and finally the file name of the<br />

desired file.<br />

Some users type ftp at their system prompt, login on the remote system, and ask for<br />

the file they want to receive. It transfers to their local host machine. (For more on this,<br />

read under "Internet" in Appendix 1.) Finally, unless their computer is directly<br />

connected to the Internet, the retrieved file must be transferred from their host machine<br />

to their PC.<br />

Where ftp or WWW is not available, you may also use FTPMAIL (chapter 12).<br />

FYI<br />

"For Your Information." A subseries of RFCs that are not technical standards or<br />

descriptions of protocols that are available from http://www.rfc editor.org and many<br />

other sources on the Internet.<br />

Gopher<br />

Gopher is a tool for exploring the Internet and to find a resource if you know what you<br />

want, but not where to find it. Gopher systems are menu based in a top level subject<br />

oriented way, and provide a user friendly front end to Internet <strong>resources</strong>, searches and<br />

information retrieval.<br />

Gopher gets information from certain locations on the Internet to which it is<br />

connected, and brings the information to your computer. It can get information via other<br />

Gophers at other locations connected to yet other hosts. <strong>The</strong> Telneting or file transfer<br />

protocols are transparent to the user.<br />

To access gopher services, run a browser program. <strong>The</strong> browser reads documents,<br />

and can fetch documents and files from other sources. Some services let you fetch<br />

gopher information by electronic mail (see Gophermail below).<br />

"Common Questions and Answers about the Internet Gopher" are posted to the<br />

Usenet newsgroups comp.infosystems.gopher, comp.answers, and news.answers every<br />

two weeks. (See FAQ above.)<br />

Pointers to Gopher sources may be given in this form:<br />

Type=1<br />

Name= United States GOVERNMENT Gophers<br />

Path=1/welcome/peg/GOPHERS/gov<br />

Host=peg.cwis.uci.edu<br />

Port=7000<br />

URL: gopher://peg.uci.edu:7000/11/welcome/peg/GOPHERS/gov<br />

If your browser cannot use this information directly, try to deduct the information from<br />

the URL line. In this example, it translates into 'gopher peg.uci.edu 7000' , select peg /<br />

gophers/ gov.<br />

If the gopher command is not available on your system, then you may telnet to the<br />

gopher site, and login as 'gopher' or 'info'.<br />
