This section only describes FTP and telnet in any detail; for other methods, FTP sites are given, so you can get information on them yourself. How to use FTP FTP (File Transfer Protocol) allows transfer of files between two computers which are on the Internet. To access the FTP areas listed here, at your system prompt type "ftp" followed by the name of the desired system. For example, to access ncardata.ucar.edu you'd type ftp ncardata.ucar.edu Use "anonymous" as your login and your email address as the password (if requested). [Note: quotes ("like this") are used to set off names of directories and files, or commands you'd type, and are not part of these names.] Not all FTP systems accept the same commands, but here's a list of the most useful: ls: list files in the current directory. cd: change directory, e.g. "cd wx" changes to the wx directory. binary: sets binary mode ascii: sets ascii mode (the default). Use for retrieving text. get: retrieves a file, e.g. "get readme" gets a file called readme. bye: exits FTP. If you can't seem to connect to the site, check to see if it is a telnet site. If it is, follow the instructions in the following section instead. If you can't FTP from your site, use one of the following ftp-by-mail servers: firstname.lastname@example.org email@example.com firstname.lastname@example.org email@example.com Send an e-mail message to the closest address, with the lines: reply firstname.lastname@example.org <- with your email address connect ncardata.ucar.edu <- for example cd datasets/ds111.2/software get access_sun.f quit For complete instructions, send a one-line message reading "help" to the server. Please don't ask me for help! How to use telnet Type "telnet" followed by the name or IP number of the desired system. These publicly accessible systems generally allow you to log in but put you in a restricted shell, from which only a certain menu of commands is available. The description for the site will include the login to use. If you can't seem to connect to the site, re-check its description in the document; if it's an FTP site, follow the instructions in the previous section instead.
