ftp101 --- An FTP client program for Minix 2.0
written by Michael Temari <Michael@TemWare.Com> release 1.01a 2006-06-07
Full download: <a href="/pub/contrib/ftp101.tar.Z">ftp101.tar.Z</a>
FTP is the File Transfer Protocol client that allows you to connect to
a remote FTP server.
This version should work equally well with Minix 2 and Minix 3.
Release 1.01a 2006-06-07: minor documentation edits
Release 1.01 2005-02-07: minor bug fix
Release 1.00 2003-12-14: added "ver" command to display current version
and an ftp(1) man page.
Installation: unpack the tarball, it will create an ftp101 directory. Although
this is a replacement for the ftp client provided in the Minix 2.0.0 and later
distributions, it is suggested you unpack and compile in the /usr/local/src
directory.
zcat < ftp101.tar.Z | tar xvfp -
Invoking make -n will show you what the Makefile will do.
make (or make ftp) compiles a new ftp binary, leaving it in the source
directory.
make install compiles the binary and installs it in /usr/bin.
make installman installs the man page in /usr/local/man/man1. The
directory must exist.
Note: there is a bug in the version of the ftp client distributed with
Minix 2.0.2 and 2.0.3 that causes a \r (0xd) character to be appended
to file names in the destination directory when files are downloaded in
binary mode using the mget command. The bug was corrected in a release
prior to 1.00.

.TH FTP 1
.SH NAME
ftp \- a File Transfer Protocol client for Minix
.SH SYNOPSIS
.B ftp
.RI [ server_name ]
.SH DESCRIPTION
.B Ftp
is a File Transfer Protocol client for Minix written by Michael Temari.
.P
There are no command line options for
.B ftp
except for the optional server name, which may be either a numeric IP address
or a domain name resolvable by DNS.
.P
If a server name is specified a connection attempt will be made, and you
will be prompted for a user name and password by the remote system.
Following the login (or immediately, if no server name was specified), the
.br
.B ftp>
.br
prompt is displayed. The following commands are accepted at the prompt:
.P
Command: Description
.br
! Escape to a shell
.br
append Append a file to remote host
.br
ascii Set file transfer type to ascii
.br
binary Set file transfer type to binary
.br
block Set file transfer mode to block
.br
bye Close connection and exit
.br
cd Change directory on remote host
.br
close Close connection
.br
clone Clone a file
.br
del Remove file on remote host
.br
dir Display long form remote host directory listing
.br
exit Close connection and exit
.br
get Retrieve a file from remote host
.br
help Display this text
.br
lcd Change directory on local host
.br
ldir Display long form local host directory listing
.br
lls Display local host directory listing
.br
lmkdir Create directory on local host
.br
lpwd Display current directory on local host
.br
lrmdir Remove directory on local host
.br
ls Display remote host directory listing
.br
mget Retrieve multiple files from remote host
.br
mkdir Create directory on remote host
.br
mod Get file modification time
.br
mput Send multiple files to remote host
.br
noop Send the ftp NOOP command
.br
open Open connection to remote host
.br
pass Enter remote user password
.br
passive Toggle passive mode
.br
put Send a file to remote host
.br
putu Send a file to remote host(unique)
.br
pwd Display current directory on remote host
.br
quit Close connection and exit
.br
quote Send raw ftp command to remote host
.br
reget Restart a partial file retrieve from remote host
.br
remotehelp Display ftp commands implemented on remote host
.br
reput Restart a partial file send to remote host
.br
rm Remove file on remote host
.br
rmdir Remove directory on remote host
.br
site Send a site specific command
.br
size Get file size information
.br
status Get connection/file status information
.br
stream Set file transfer mode to stream
.br
system Get remote system type information
.br
user Enter remote user information
.br
ver Display client version information
.SH "SEE ALSO"
.BR ftpd (8),
.BR ftpget (1).
.SH NOTES
The FTP protocol passes unencrypted usernames and passwords to clients,
so they are potentially exposed to evildoers with network sniffers. So be
wary of using this to exchange files between your own accounts. Obviously
if you have a root account on another system and the remote system will
accept a login as root this is extremely dangerous. (Many ftp servers will
not allow a connection by root).
.P
Text-mode (ASCII) transfers are the default mode, be sure to enter the
"binary" command if you are downloading a program file or a compressed
archive, in fact anything other than a text file from a machine with a
different text-file format than Minix uses.
.P
If you are behind a firewall you probably need to use passive mode to
successfully transfer files.
.SH BUGS
None are known, but there may be some unknown ones. Version 1.00 corrects
a bug in previous versions that would append a \\r (0xd) character to file
names on the destination when an mget transfer was used in binary mode.
.SH AUTHOR
The Minix httpd server was created by and is maintained by Michael Temari
<Michael@TemWare.Com>. The earliest version was released in 1992, for use
with Michael's TNet networking extensions for Minix 1.5.
