- GETTING BINARIES VIA FTP
-
- Entire contents Copyright (c) 1989 by Brian O'Neill. This manual was
- created to aid people in the usage of binary postings on UseNet.
- Permission to copy this file is granted, so long as credit is given to
- those who helped. A list of those people appear at the end of this
- posting.
-
- FTP stands for File Transfer Protocol. It allows a person to transfer
- files between two systems, generally connect over Ethernet networks or
- long-haul networks, such as the Internet.
-
- If your hosts system has FTP and is connected to the Internet, you
- can access very large amounts of archives available on a number of
- systems, such as Simtel20 or uunet.uu.net. This is a simplified use
- manual, and will use two examples, one a TOPS-20 system
- (wsmr-simtel20.army.mil), and one Unix system (swan.ulowell.edu, my
- local system).
-
- The simplest way to initiate FTP would be to give the command 'ftp
- <system-name>', where <system-name> is the remote system you are
- connecting to, either a name (wsmr-simtel20.army.mil, if you have an
- entry in /etc/hosts or are accessing a Domain-name Server) or the InterNet
- address (26.2.0.74, for Simtel20). After a short wait, you will be prompted
- for your username. If you do not have an account on the remote system, some
- systems allow you to use 'anonymous'. This gives you a restricted
- access path.
-
- You would then be prompted for a password. Some systems will tell
- you to send your real identity as the password. What you type doesn't
- matter, but it is suggested to give your mail address. Other systems
- need a password of 'guest', or something similar.
-
- After that, you should receive the FTP prompt (usually ftp>), and
- now have access. You can get a directory of files be giving a 'dir'
- command, or if the remote system is Unix-based, 'ls -l' will give the
- familiar output. On Simtel20, there is a file available in the
- default anonymous ftp directory that explains what Simtel20 is, and
- where files are located. The name is 'SIMTEL-ARCHIVES.INFO.nn, where
- ".nn" is a file generation number. You don't need to specify the file
- generation number when requesting the file. In fact, it's better not
- to because you will always get the latest generation that way.
-
- Unix systems will all have the familiar directory structure, and
- moving around is done with the familiar 'cd' or 'cwd' command.
- TOPS-20 systems have a different structure, but movement is still
- accomplished with the 'cd' command.
-
- I will use Simtel20 as the first example. To start, give the
- command 'ftp wsmr-simtel20.army.mil' from your shell prompt, or 'open
- wsmr-simtel20.army,mil' from the 'ftp>' prompt. If this host is not
- in your /etc/hosts file or you do not have access to a Domain-name Server,
- use '26.2.0.74' in it's place. After a few seconds, you'll be prompted
- for your username. Type 'anonymous', and when prompted for password,
- give your e-mail address (more as a courtesy than anything else), or if
- you prefer, 'guest'. You should then shortly get back the 'ftp>' prompt.
- If you receive an error message stating that there are too many anonymous
- logins, wait a few minutes and try again. Simtel20 has limited access,
- especially during normal business hours.
-
- Now, say you want to see what is stored for MS-DOS programs.
- Simtel20 is a DEC System-20 running the TOPS-20 operating system. The
- directory structure is 'DISK:<DIRECTORY.SUBDIRECTORY>'. For MS-DOS
- programs, the main directory is 'PD1:<MSDOS>'. In here there is a
- file called 'MSDOS.CRCLST', which is updated almost daily. It
- contains a list of all files within the MS-DOS subdirectories, along
- with file size and CRC value.
-
- To get this list, first switch to that directory by saying 'cd
- pd1:<msdos>' (TOPS-20 is not case sensitive). If you are prompted for
- another password just ignore the request. When you get the 'ftp>'
- prompt back, you can then say 'get msdos.crclst'. This will initiate
- the transfer, and after a few minutes it will be completed. The
- beauty of Unix is that while you are transfering something big, you
- can put it in the background and do something else.
-
- Say you wanted to get ProComm Plus. According to the list, it is
- in PD1:<MSDOS.PROCOMM>. So, you can enter 'cd pd1:<msdos.procomm>'.
- A 'dir' will show all the files in that directory. (You may wish not
- to use too many 'dir' commands, as they are sometimes fairly slow).
-
- Now, you want the file 'pcplustd.arc'. First, you must tell your
- host what kind of file it is. On most Unix systems, 'binary' or 'set
- type binary' or 'set type I' will work. However, as Simtel20 runs a
- different OS that has different word sizes (36 bits) you must specify
- 'tenex' or 'type L 8' to transfer properly. You can then issue a 'get
- pcplustd.arc' command, and after a short while, you have ProComm Plus.
- To end your session, enter the 'bye' command.
-
- Unix is a little more familiar for most people with Internet access.
- For example, you might wish to get the latest version DSZ from
- swan.ulowell.edu. First, you give the 'ftp swan.ulowell.edu' command (or
- ftp 129.63.224.1), giving 'anonymous' for the username, and your address
- as the password. You can then use the 'dir' or 'ls -l' commands to scan
- the directories. After logging in, you'll notice a directory called
- 'ibmpc'. You can use 'cd ibmpc', and you're inside.
-
- The ibmpc directory is subdivided into different subdirectories,
- such as Comm, SysUtil, and Programming. DSZ is a communications
- program, so you can then 'cd Comm'. Once again, there are several
- subdirectories, giving the names of several communications programs,
- and one marked 'Protocols'. Inside that directory is where DSZ is
- located. There you'll find the latest version of DSZ (dsz0319.arc at
- this time). Since it is a binary file, you must give the command
- 'binary' or 'set file type binary' to let FTP know. Then you can
- issue the 'get' command.
-
- Different systems have different organizations for their files,
- and the above example is just the way I have it set up. By 'poking'
- around other systems, you can learn how their files are set up, and
- zip around much faster. Note, however, that FTP will not allow you
- outside the FTP 'root' directory, usually ~ftp on most systems. So,
- poking about the entire system is not permitted.
-
- Other features of FTP can be found in the manual - please check there.
-
- Messages regarding problems, complaints or suggestions for
- Simtel20 should be addressed to 'action@wsmr-simtel20.army.mil'.
