Accessing Internet Tools on the AFS Login Servers
Once an E-mail account is generated, you can access your account by using Terminal (Mac OS X users), NCSA Telnet or Better Telnet (for Mac OS 7.x -9.x users), Hummingbird Host Explorer or Windows Telnet (for PC users) to login to either libra or apollo. Below are Internet tools you can use while you are logged on to your account.
ELECTRONIC MAIL allows you to communicate electronically with another user on the Internet network. Your own electronic mail address is username@sfsu.edu (i.e., username is the information you provide at the login: prompt). You must know the electronic mail (email) address of the recipient you want to communicate with. You work with your electronic mail through an email program: Pine is a menu driven mail program for electronic communication on the Internet network. Type pine at the Unix command prompt (e.g., libra% pine) to begin your email experience. Use the Pine menu options to send, read or manage your email. On-line help is available in Pine by selecting the help key (? in the Pine main menu and CTRL-G in the other Pine screens).
Note: elm and mail are alternative email programs you can also use but they are not as user-friendly as pine.
USENET is an Internet-based news discussion group or bulletin board system. News groups are organized into seven major categories: comp (computer science and related topics), news (Usenet news and software), rec (recreation related topics), sci (scientific research and applications), soc (social issues), talk (forum for debating controversial topics), misc (miscellaneous related topics). For example, the newsgroup comp.sys.mac.graphics is a discussion of graphics for the Macintosh computer system. Newsgroups are added and removed frequently.
You access the Internet-based newsgroups with a newsreader program called tin. Tin is a menu driven newsreader to access the Usenet discussions. Type tin at the Unix command prompt (e.g., libra% tin) to begin your Usenet newsgroup reading experience. You subscribe to newsgroups you are interested in by typing an s in front of the newsgroup name and unsubscribe to newsgroups by typing a u in front of the newsgroup name. Use the tin menu options, displayed on the bottom of each tin screen, to read, post, or manage your subscribed newsgroups. On-line help is available in tin by selecting the help (h) key.
Note: trn is an alternative usenet reader you can also use but it is not as user-friendly as tin.
FILE TRANSFERS involve transferring files between two networked machines. Some Internet servers offer anonymous (public) ftp access for users to retrieve public domain/shareware software and documents. You must know the name of the software and document and the name of the anonymous ftp site. You connect to an ftp site with the ftp program. Type ftp host-name (e.g., ftp ftp2.sfsu.edu) to connect to another ftp machine. For a non-public ftp site, you must have a valid user name and password on the system. For an anonymous ftp site, you login with the user name "anonymous" and use your "email address" as the password. Use the following ftp commands to work with your ftp session:
cd directory-name to traverse to different directories dir to view the files and directories get filename to retrieve files to your machine put filename to put files on the remote machine On-line help is available in ftp by typing the help command (ftp> help).
WORLD WIDE WEB consists of information servers that provide multimedia information through hyperlinked connections between different information servers. To access the web, you run a browser program. The browser reads documents, and can fetch documents from other sources. Information providers set up hypermedia servers which browsers can get documents from. On our Unix servers, use a browser called lynx to navigate around the World Wide Web. Type lynx at the Unix command prompt (.e.g., libra% lynx) to begin exploring different types of Web resources. On-line help is available in lynx by selecting the help (h) key.
NOTE Most of the Internet tools described in this document can also be invoked from a menu program. Type menu at the Unix command prompt to access these internet tools (e.g., apollo% menu).
Additional on-line information about these Internet tools are available by typing man program (e.g., man pine) at the Unix command prompt.
If you have questions about these Internet tools, contact the Division of Information Technology's Help Desk (ADM 110) at 338-1420.
