Archives of correspondence for several newsgroups are also available. You can obtain these files using the InterNet file transfer protocol, FTP (described in a following paragraph), with user-name "anonymous". For a login password, use "guest", your host-name, or any other string of printing characters. Throughout this message, FTP examples are given in a GENERIC syntax. You will have to consult either local documentation or your friendly system wizard to learn the actual syntax used with your local mainframe operating system. For the sake of brevity, the full host name "WSMR-SIMTEL20.ARMY.MIL" will be dropped from further references to SIMTEL20 in this discussion. To obtain directory listings, connect to SIMTEL20 via FTP and do this: get pd1:msdos.crclst get pd2:msdos2.crclst get pd1:pc-blue.crclst get pd2:cpm.crclst get pd2:cpmug.crclst get pd2:sigm.crclst get pd3:macintosh.crclst get pd3:misc.crclst get pd2:unix-c.crclst get pd2:ada.crclst There is also a comma-delimited directory listing in each top-level directory, FILES.IDX, which is suitable for importing into a database program. This file may be of greater use than the crclst files because it can be compared against an earlier version of the same file to produce a complete list of files added and deleted from the archives. Using the comma-delimited fields it is possible to build a script for FTP to maintain a parallel archive. FILES.IDX can be printed or displayed with a simple BASIC program. For more information see PD1:AAAREAD.ME. The , , and archives are the ones to watch for the very latest offerings, as they are updated frequently. The , and archives contain software distributed by the CP/M Users Group, the SIG/M Users Group and the PC-Blue Users Group respectively. This software is available on diskettes from the associated user groups, and the archives are updated as new volumes are issued. The archive contains software for the IBM-PC and similar machines. The and archives also contain software for the MSDOS and PCDOS operating systems; but these archives are locally managed, and therefore are updated more frequently than the archive. The archive contains a variety of UNIX tools. Those which apply specifically to CP/M are in the directory . The archive is growing rapidly. Information about this archive is in directory PD2:. In general, the archived software is very good, having been worked-over and refined by many users. The documentation and comments tend to be complete and informative. Files in all of these archives can be obtained using the FTP procedures described in this message. PLEASE NOTE: Due to the large number of files available, the archive maintainers cannot possibly attempt to validate the proper operation of the various programs. When a program bug is reported, immediate action is taken to either correct the error or remove the offending program from the archives. Still, users must understand that all archive programs are offered AS IS, and the archive maintainers specifically disclaim any liability should these programs malfunction or cause damage, incidental or otherwise. When testing ANY new software, be certain that all information stored on disk is backed-up before you start, so that you can recover if files are damaged or erased. This is particularly true if you have a hard disk, in which case malfunctions can be spectacularly disasterous. FILE TYPES Files are stored in two formats: Text files such as those with names that end with DOC, HEX, INF and ASM are sometimes stored as ASCII files, but sometimes these files are stored in binary compressed form. Binary storage is also used for executable (COM and EXE) and library/archive files (LBR and ARC). All binary data are stored as four 8-bit bytes per 36-bit SIMTEL20 word, with the low-order four bits of each word filled with zeros. If such a file is interpreted as a contiguous string, as will happen if a straight binary transfer is made to a 16 or 32-bit UNIX machine, the four zero filler-bits per 36-bit group will cause rather bizarre and frustrating results. For information on ARC, ARK, LBR, squeezed and crunched files, get PD2:-FILES.DOC and/or PD1:-FILES.DOC. Although the type of storage used for a particular file can usually be inferred from the file-name, this is not always true. It is a good idea to check the appropriate "crclst" file to ascertain the storage format used for each file of interest. Now, and for the foreseeable future, storage formats for files in the , and archives can be determined from their "generation numbers", as shown by the FTP directory command. For example, the FTP command: dir pd1: will yield results of the form: -CATALOG.001.2 ABSTRACT.001.2 BW.ASM.2 BW.BAS.1 BW.EXE.1 COLOR.ASM.2 COLOR.BAS.1 COLOR.EXE.1 ...and so on All files with names ending in ".1" are stored in binary format, and those with names ending in ".2" are stored in ASCII. This relationship will continue to apply for files in the , and archives until further notice. WARNING: Because the public domain archives on SIMTEL20 consume a huge amount of disk space, storage capacity will be conserved by the greatest practical use of libraries, archives, crunched and squeezed files, all of which are stored in binary format. If you cannot properly transfer binary files, you are going to be VERY FRUSTRATED! If you need help, please contact your local system wizard and provide him/her with a copy of this message. Having done that, if you are still unable to make things work correctly, send a message to Action@WSMR-SIMTEL20.ARMY.MIL and someone will try to help you. Please provide the following information: 1. Machine and operating system (e.g., VAX-11/780, 4.3 BSD UNIX) 2. Network software in use (e.g., 3-Com UNET) 3. Complete list of available FTP commands (e.g., GET, PUT, etc.) Important files in the and archives are the CATALOG files. These files, which are stored in ASCII, contain the "-CATALOG.nnn" files from all the volumes of their respective archives. To obtain these composite catalog files, connect to SIMTEL20 via FTP and do this: get pd2:cpmug.cat get pd1:pcblue.cat Similar files exist for the archive, but they are stored in squeezed form. These files, when unsqueezed, yields SIG0.CAT and SIG1.CAT (the catalog). They can be obtained using the FTP command: get pd2:sig0.cqt get pd2:sig1.cqt (NOTE: That's "L-and-three-zeros" in "vol000") FILE TRANSFER VIA FTP FTP stands for File Transfer Protocol, a formalized procedure for moving files among machines on the Defense Data Network (DDN) and other networks that connect with the DDN. The protocol is implemented by a program often called FTP. The different mainframe operating systems implement FTP with variations in command syntax. Some systems have the remote-file-name precede the local-file-name in the command. Others reverse this order. Some versions have the whole command on a single input line, while others use multiple lines. Read the documentation for your local system, or consult a friendly system wizard for the details of your local FTP command syntax. UNIX users can do something like "man ftp" for on-line instructions. However, not all UNIX FTP programs are called "ftp", so you may have to snoop around in the system directories or ask a system wizard for the correct local name to use with the "man" command. ITS users can do ":INFO FTP", and "HELP FTP" works on TOPS-20 and some other operating systems. I will be happy to update this message with pointers to other sources of on-line documentation if they are sent to w8sdz@WSMR-SIMTEL20.ARMY.MIL. FTP transfers from SIMTEL20 can be made with user-name "anonymous". Use GUEST for the password. For anonymous logins, SIMTEL20 supports the FTP "change working directory" command. (Your local syntax may be something like CD, or CWD). Ignore the message which may appear that prompts you to enter a password. This command allows you to specify a default SIMTEL20 directory to be used for all file retrievals, and thereby relieves you from having to repeatedly type "pdx:" as part of each filename. For example, you can do something like this: cd pd2: get filename-1 get filename-2 ...and so on instead of using the longer filename forms shown in previous examples. Users of TOPS-10, TENEX, TOPS-20 or ITS systems can use "image" or "paged" mode for ALL transfers. UNIX users must use "ascii" mode for ASCII files, and "type tenex" or "type L 8" mode for binary files. MULTICS users can use "ascii" mode for ASCII files, but binary files require special treatment that is best described by the following example provided by Paul Schauble : !ftp simtel20 220 WSMR-SIMTEL20.ARMY.MIL FTP Server Process 5Z(14)-7 at [date/time] user_ftp: !login anonymous 331 ANONYMOUS user ok, send real ident as password. Password: !guest user_ftp: !quote "type l 8" <--(NOTE: That's lowercase "L" 8.) 200 Type L bytesize 8 ok. user_ftp: !get micro:alias.hlp alias.hlp 150 Retrieve of MICRO:ALIAS.HLP.1 started. 226 Transfer completed. Total elapsed time: 35.7 seconds. 4348 bytes transferred in 18.5 seconds (1850 bits/sec). user_ftp: !quit 221 QUIT command received. Goodbye. Lines beginning with "!" are typed by the terminal user. The received files are stored on MULTICS with one 8-bit byte per 9-bit word, and can be transferred to a microcomputer with Kermit (described in a following paragraph). All aspects of the FTP process for UNIX machines have been automated to a high degree by a program in directory PD3:. With this program, a simple command like "sh autoftp30.sh mylist &" can be run in no-hangup background mode to transfer multiple files from SIMTEL20 without the user even remaining logged-in on the local system. For more information, get the file PD3:AUTOFTP30.TAR-Z, a compressed tar archive. After transferring it to your Unix host, rename to autoftp30.tar.Z, uncompress, and extract with tar. NEWSGROUP CORRESPONDENCE ARCHIVES Copies of correspondence for several newsgroups are kept on SIMTEL20 in directories with names of the form PD2:, where "KEYWORD" has been chosen to indicate the associated newsgroup. At present, the following correspondence archives are available: newsgroup mail archive filename --------------- --------------------- ADA-SW PD2: AMETHYST-USERS PD2: INFO-68K PD2: INFO-APPLE PD2: INFO-CPM PD2: INFO-FORTH PD2: INFO-HAMS PD2: INFO-MICRO PD2: INFO-MODEMS PD2: INFO-XMODEM PD2: INFO-MODEMXX PD2: INFO-MODULA-2 PD2: NORTHSTAR-USERS PD2: PACKET-RADIO PD2: INFO-PASCAL PD2: UNIX-SW PD2: VIDEOTECH PD2: INFO-XENIX310 PD2: Descriptions of these and other newsgroups can be obtained via FTP with anonymous login (as for SIMTEL20) from the Network Information Center's host SRI-NIC.ARPA. Ask for the file PS:INTEREST-GROUPS.TXT (an ASCII file). And please note, this is NOT on SIMTEL20. File names for SIMTEL20 newsgroup correspondence archives have two forms. For example, in PD2:, which holds the INFO-CPM correspondence (the "INFO-" is assumed), the forms are: yymm.n-TXT or yymm.n-TXT-Z. Files with names ending in -Z were compressed with a Unix compress-compatible program. The characters "yymm" in the file names are the digits of the year and month of the messages in each particular file. The "n" was incremented as overflowed 150 disk pages (approximately 375K). The current month's correspondence is kept in CPM-ARCHIV.TXT, which is constantly growing as new messages arrive. There may also temporarily exist files named CURRENT.n-TXT, which hold the overflow of the current month's messages when CPM-ARCHIV.TXT is split into monthly files. Although INFO-CPM has been used as an example here, the same naming scheme is used for the other newsgroup files as well. For a complete list of available files, connect to SIMTEL20 via FTP and do this: dir PD2: You will receive a list of names of the form: KEYWORD.DIRECTORY.n where "n" is one or more digits. For example, the INFO-CPM listing currently appears as "CPM.DIRECTORY.1" To then get a list of files in a particular archive, do this: dir PD2: where "keyword" (for example, "cpm") is chosen from the preceding list, and the word "directory" and the number "n" are not used. At present, all of these files are stored in ASCII. FTP PROBLEMS, FILE ERRORS, CONNECT OR LOGIN PROBLEMS System-related problems should be reported to ACTION@WSMR-SIMTEL20.ARMY.MIL.
