From: William H. Barker Department of Mathematics Bowdoin College Brunswick, Maine 04011 barker at bowdoin.edu (207) 725-3571 Date: March 24, 1993 Subj: Instructions for FTP receipt of Project CALC Mathematica labs. It is now possible to obtain the Mathematica labs produced at Bowdoin for Duke University's Project CALC program via anonymous ftp. This document tells you how this is done. If you are unable to use this method and would prefer to receive the labs on disks via ordinary mail, send me such a request. Currently Release 6 of our materials has been placed in the ftp area. Detailed descriptions of the contents of this release will be found in the document rel6-ReadMe. Release 6 contains the versions of the laboratory notebooks that were current as of mid-February. All are fully compatible with Mathematica v2.1 Laboratories 31 through 37 are currently posted in "preliminary form." Revision of these notebooks will be complete by the end of April, and the new versions will be posted in the "revisions" directory in our ftp area. Those of you interested in having the most current versions of our labs and packages should check this directory on a regular basis. If you wish to receive information from us on a regular basis, please send a request asking to be placed in our "Dissemination Network." Currently printed versions of the first and second semester labs can be obtained from D. C. Heath (the publisher for all Project CALC materials) in the form of a laboratory manual (preliminary version). The third semester labs will also be available in this form by the fall. Versions of our laboratories that were current as of September 1992 are available for NeXT computers. (This would be essentially Release 5+.) These notebooks will be found in the "NeXT" directory in our ftp area, along with further information on converting notebooks from one hardware platform to another. What follows is a sample ftp session along with some explanatory comments; this should enable you to obtain any currently posted file. I wish to thank my colleague Steve Fisk for designing and setting up this ftp directory. Note: For those of you who need it, the Bowdoin's numerical Internet address is 18.104.22.168. ---------------------------------------------------------------------------- Log on to a computer with Internet access and enter ftp polar.bowdoin.edu You will be answered by the following statements: Connected to polar.bowdoin.edu. 220 polar.bowdoin.edu FTP server: ready. Now login with the username 'anonymous' and your e-mail address as the password. Name (polar.bowdoin.edu:): anonymous 331 Guest login ok, send ident as password. Password:your-e-mail-address 230 Guest login ok, access restrictions apply. You now can connect to the appropriate directory. Depending on what you wish to receive, the last phrase in the directory name will be either release-6, revisions, or NeXT. ftp> cd pub/calculus/release-6 250 CWD command successful. You now can ask for a list of what is in the directory ftp> dir 200 PORT command successful. 150 Opening data connection for /bin/ls (22.214.171.124,1186) (0 bytes). total 3795 -r--r--r-- 1 801 502 872 Mar 11 09:00 rel6-ReadMe -r--r--r-- 1 801 502 1391872 Mar 10 15:43 rel6-labs01-25.sea -r--r--r-- 1 801 502 1276672 Mar 10 15:43 rel6-packages.sea -r--r--r-- 1 801 502 1384192 Mar 10 15:43 rel6-solns01-25.sea 226 Transfer complete. 210 bytes received in 0.17 seconds (1.2 Kbytes/s) To transfer an individual file use the following command: ftp> get rel6-ReadMe To transfer all the contents of the current directory use the commands ftp> mget * mget rel6-ReadMe? yes (you will be asked about each file) To change to one of the other directories use the commands ftp> cdup 250 CWD command successful. ftp> cd ./revisions To quit: ftp> quit -------------------------------------------- Once the desired files have transferred to your Internet-connected computer, the ReadMe files can be opened immediately. The remaining files must be transferred to a Macintosh and decompressed: they are in the form of Self- UnStuffing StuffIt Archives. You do not need to have special software to perform the decompression. At Bowdoin we transfer files of this nature from POLAR (a UNIX workstation) to a Macintosh via TCP/Connect. The settings needed for this transfer are 'Image' and 'MacBinary'. Other users have indicated that "Fetch" also works nicely. We have, however, heard of problems when using "MacIP"---for that reason we suggest not using this program when working with our files.
