- BITFTP -- Princeton BITNET FTP Server
-
- BITFTP provides a mail interface to the FTP portion of the IBM
- TCP/IP product ("FAL") running on the Princeton VM system, to allow
- BITNET/NetNorth/EARN users to ftp files from sites on the Internet.
-
- To use BITFTP, send mail containing your ftp commands to BITFTP@PUCC
- (or to BITFTP@PUCC.Princeton.edu).
-
- The first command to BITFTP must be "FTP", "FTPLIST", "HELP", or
- "VMS". If you send BITFTP mail or a message containing only the
- command "FTPLIST", it will send you a list of some of the hosts that
- allow anonymous ftp. (Note that there is no guarantee that BITFTP
- can access all the hosts in that list.) Use "HELP" to request a
- current copy of this help file. Use "VMS" to request a collection
- of tips provided by BITFTP users on how to handle binary files from
- BITFTP on VMS systems.
-
- The recommended syntax for FTP requests is:
-
- FTP hostname NETDATA --or-- FTP hostname UUENCODE
- USER username password
- <other ftp subcommands>
- QUIT
-
- Following the hostname on the FTP command, you may specify
- "UUENCODE" or "NETDATA" to tell BITFTP the format in which you wish
- to receive files.
-
- If the username is "anonymous", no password is required; BITFTP will
- use your userid and nodeid as the password. Note that on many
- systems passwords are case-sensitive; that is, the password may be
- required to be in lower case or mixed case or upper case. (The same
- is true of directory and file names.)
-
- The following is an example of an ftp request:
-
- FTP f.ms.uky.edu NETDATA
- USER anonymous
- CD /pub/msdos/Games
- DIR
- BINARY
- GET robotron.arc msdos.robotron
- QUIT
-
- BITFTP implements a subset of the ftp subcommands provided in the
- IBM TCP/IP and uses the same syntax. Therefore, you may find it
- useful to obtain the "IBM TCP/IP for VM Command Reference Manual",
- IBM order number GC09-1204.
-
- The currently supported subcommands are:
-
- ACCT -- to send host-dependent account information.
- format: ACCT account-information
-
- ASCII -- to change the file transfer type to ASCII.
- format: ASCII
-
- BINARY -- to change the file transfer type to image.
- format: BINARY <FIXED record-len> <VARIABLE>
-
- CD -- to change the working directory.
- format: CD directory
-
- CLOSE -- to disconnect from the foreign host.
- format: CLOSE
-
- DIR -- to get a list of directory entries.
- format: DIR
-
- EBCDIC -- to change the file transfer type to EBCDIC
- format: EBCDIC
-
- GET -- to get a file from the foreign host.
- format: GET foreignfile <localfile>
-
- If you specify "localfile", it must be in
- the forms "filename.filetype" or "filename",
- and the filename and filetype may each be no
- more than 8 characters long and may not contain
- periods.
-
- LOCSTAT -- to display local status information.
- format: LOCSTAT
-
- LS -- to list the files in a directory.
- format: LS <name>
-
- PWD -- to print the working directory.
- format: PWD
-
- QUIT -- to disconnect from the foreign host.
- format: QUIT
-
- STATUS -- to retrieve status information from a foreign host.
- format: STATUS <name>
-
- SYSTEM -- to get the name of the foreign host's operating
- system.
- format: SYSTEM
-
- TYPE -- to specify Image, ASCII, or EBCDIC file transfer.
- format: TYPE <I|A|E>
-
- BITFTP does not provide a PUT capability, and there is no intention
- to make it do so in the future.
-
- BITFTP currently accepts requests only via RFC822-format mail, IBM
- NOTE-format mail, PROFS-format messages, or files with no headers at
- all. BITFTP currently returns the requested files as NETDATA-format
- files or as mail files containing UUENCODED data. If you specify
- "UUENCODE" or "NETDATA" on your "FTP" command, BITFTP will attempt
- to use that format. If you do not specify the format, BITFTP will
- attempt to select the appropriate format for your node.
-
- UUENCODED files are broken up into mail files that contain no more
- than 50,000 bytes of data. NETDATA-format files that are larger
- than 300,000 bytes are sent in 300,000-byte pieces using the BITSEND
- function. You should be able to receive such files using the BITRCV
- function available from your nearest NETSERV. (If you do not know
- how to use NETSERV, ask your local BITNET/EARN/NetNorth Coordinator
- for assistance.) If BITRCV is not available for your system, use
- the command you normally use to receive NETDATA-format files and
- then concatenate the files in the order shown in the BITRCV control
- file to recover the original file.
-
- Users in the UK should note that BITFTP attempts to send
- NETDATA-format files through the gateway from EARN into Janet via
- the NIFTP facility at Rutherford Lab. Note that receiving files via
- NIFTP requires an overt action on your part. If you are at a Janet
- node and don't know how to use NIFTP, you should ask for assistance
- locally. Alternatively, you can ask BITFTP to send your files
- UUENCODED inside mail by specifying the "UUENCODE" option.
-
- If BITFTP sends you a file you cannot read, THE FIRST THING TO DO is
- to make sure that you specified ASCII if the file should contain
- textual material or that you specified BINARY if the file should
- contain binary data, executable programs, tar files, or the like.
- VMS users should specify BINARY F 512 and should use RECEIVE/BINARY
- to receive the NETDATA-format binary files BITFTP sends them.
-
- If BITFTP sends you a uuencoded file that you cannot uudecode, the
- first thing to do is to translate all occurrences of 0x7E in the
- file to 0x5E and then try uudecoding again. (Some gateways are
- changing 5Es to 7Es when the files pass through them.)
-
- There are many different flavors of UUENCODE/UUDECODE. The version
- that BITFTP uses puts a "guard character" at the end of each encoded
- line. Most implementations of uudecode know to ignore this
- character. If yours does not, then you should remove the last
- character of each line before attempting to uudecode the file. Note
- that the guard character is not always "M"; the short lines at the
- end of the file may have some other guard character, rather than
- "M". Whatever that character is, it should be removed (or your
- uudecode should be fixed).
-
- When BITFTP is told to transfer a file in FIXED format, such as
- "BINARY FIXED 128", it will create a file whose total byte count is
- an integral multiple of the record length (128, in this case). This
- means that the last record may be padded to get it to the specified
- record length. In such a case, you may need to use an editor to
- shorten the last record so that the total byte count in the file is
- correct. (If the file is uuencoded when you receive it, shorten it
- AFTER you have uudecoded it.)
-
- In addition to any files you request, you will also receive a mail
- file containing a log of your ftp session. In that mail file,
- entries prefixed by ">" are your original commands; those prefixed
- by ">>" are your commands as interpreted by BITFTP and passed to
- TCPIP; those prefixed by ">>>" are your commands as interpreted by
- TCPIP and passed to the remote host; those prefixed by "<<<" are
- messages from the remote host; and those prefixed by ">>>>" are
- completion messages from BITFTP.
-
- If BITFTP is unable to connect to the host you specify, it will send
- you mail after the first attempt, but will keep trying at intervals
- over three days. The only additional mail file you will receive
- will be when the connection is made successfully or when BITFTP
- gives up after three days.
-
- The load on BITFTP is often very heavy, and network backlogs are
- often so great that it may take several days for a file to get to
- you once BITFTP sends it, so please be patient and don't send
- multiple requests for the same file. If your system allows you to
- send interactive messages, you can inquire about BITFTP's backlog by
- sending the query "How are you?", e.g., on a VM system:
-
- TELL BITFTP AT PUCC How are you?

- directed to Melinda Varian, MAINT@PUCC on BITNET or
- maint@pucc.princeton.edu on the Internet.
