NAME
LLNL XFTP - an X-based interface to FTP
SYNOPSIS
xftp [options]
DESCRIPTION
LLNL XFTP is a graphical user interface to FTP (File
Transfer Protocol). LLNL XFTP does not execute the ftp pro-
gram; instead, it directly communicates with remote FTP
servers. LLNL XFTP is an X client and follows the OSF/Motif
look-and-feel. LLNL XFTP enables users to transfer files
and perform various directory manipulation commands, both
remotely and locally. Two especially notable features are
the ability to (1) perform "third-party" file transfers, and
(2) transfer or delete entire directory substructures.
LLNL XFTP's main window is divided into five main sections:
(1) the main menu bar at the top of the window, (2) the
diagnostics log at the bottom, (3) the file transfer con-
trols in the center, and (4 and 5) the "left" and "right"
host sections to either side of the file transfer controls.
LLNL XFTP can be connected to zero, one, or two hosts. The
hosts may be any combination of local and remote hosts (the
local host is the client host upon which LLNL XFTP is run-
ning). In this document, a connected host is referred to as
either the "left" or "right" host, depending on whether it
is displayed in the left or right host section, respec-
tively.
Each host section consists of four major graphical elements:
(1) a label which displays the host's name; (2) a menu bar
whose menus contain many commands that operate on the host;
(3) a "directory" menu; and (4) a scrollable "directory
list."
Each host's Connect menu contains commands for
connecting/disconnecting local and remote hosts.
Each host's Dir menu contains various commands for creating
new directories, and for changing and displaying the current
directory.
Each host's Select menu contains commands for
selecting/deselecting entries in the current directory (the
selections appear in the scrollable list of directory
entries).
Each host's Ops menu contains several commands that operate
on selected directory entries.
Each host's directory menu contains each link of the path of
the current directory (the last link is displayed). By
selecting a link in the path, the current directory is
correspondingly changed. (Hence, this is a mechanism to
traverse up the host's directory structure.)
Each host's directory list contains the entries of the
current directory. One way to select/deselect a directory
entry is to click on it. If an entry is double-clicked, an
attempt is made to change the current directory to that
entry. (Hence, this is a way to traverse down the host's
directory structure.)
The file transfer controls in the middle of the main window
allow the user to initiate file transfers on selected
entries. The transfers can go from left to right or from
right to left. Angle brackets in the Copy and Rcopy buttons
indicate the direction of the transfer (e.g., ">>Copy>>"
indicates that a left-to-right transfer would take place).
The View button causes the selected file to be displayed.
The scrollable diagnostics log window at the bottom of the
main window displays error and status information. The user
can control the level of verbosity of messages written to
this window via the user preference Diagnostics. The con-
tents of this window can be saved to a file by selecting the
Save Log item in the Log menu. The diagnostics window can
be cleared by selecting the Clear Log item in the Log menu.
There is a flag to the left of the diagnostics log window
that indicates whether an operation completes successfully
or not. If an operation fails then (1) a beep is emitted,
(2) the flag changes from green to red (white to black on
monochrome displays), (3) the "OK" in the flag changes to
"E", and (4) an error message is written to the diagnostic
log window. The next operation will clear the error flag.
LLNL XFTP automatically caches (1) wildcard expressions, (2)
paths of current directories, (3) host names and user names
used in connecting to remote hosts, and (4) quoted commands.
The purpose of each cache is to reduce the amount of typing
required. For example, when the user wishes to apply a
wildcard expression to select directory entries, a list of
recently referenced wildcard expressions for that host will
be presented to the user; the user can then double-click on
an existing wildcard expression to apply it. The cache is
automatically preserved across LLNL XFTP sessions in a file
named ".xftpcache" in the users home directory.
OPTIONS
LLNL XFTP accepts all of the standard X Toolkit command line
options, as well as the following option:
-color
Force LLNL XFTP to use a nice color scheme, even if the
application defaults file, XFtp, is not found.
GETTING STARTED
Use the Connect menus to connect the two sides to the
desired combination of local and/or remote hosts. (Depend-
ing on how the user preferences are set, when LLNL XFTP
comes up some combination of the left and right sides might
already be connected to the local host.)
Once connected, traverse through a host's directory struc-
ture by (1) using the directory name menu (the menu just
above the directory list), (2) double-clicking on entries in
the directory list, (3) selecting an item in the Go to Pre-
vious Directory submenu in the host's Dir menu, or (4)
selecting the Change Directory item in the host's Dir menu.
Obtain different types of views into a host's current direc-
tory by selecting the Display Directory (Long) or Display
Directory (Table) items in the host's Dir menu.
Select/deselect directory entries to operate on by (1)
single-clicking on entries in the main directory list, (2)
single-clicking on entries in the tabular directory list,
(3) dragging the mouse with the left button held down over
entries in the tabular directory list, or (4) by selecting
any of the items in the host's Select menu.
Transfer selected items by clicking on the Copy or Rcopy
(recursive copy) buttons. Be sure to first set the file
transfer mode by toggling the appropriate button (ASCII or
Binary) in the main window.
View a selected file by clicking on the View button. Con-
figure the viewer by selecting item Viewer Preferences in
the Options menu. Be sure to first set the file transfer
mode by toggling the appropriate button (ASCII or Binary) in
the main window.
Perform other types of operations on selected items by
selecting any one of the items in the host's Ops menu.
Configure LLNL XFTP by selecting the Preferences item in the
Options menu.
COMMANDS
LLNL XFTP contains a large number of commands. The commands
are found in (1) the main menus, (2) the host menus, and (3)
in the Xfer Ops controls. Here is a list of the commands:
About LLNL XFTP (in File menu)
Gives version information.
Change Directory (in Dir menus)
Change the current directory. A dialog pops up to
prompt for the directory to change to. The directory
may be specified with a full or relative path. Previ-
ously referenced directories are cached and displayed
in a scrollable list. Double-click on a path in the
list to change to that directory. Single click on a
path in the list to place that entry into the text
field labeled "Directory:", where it can be edited.
Click on the OK button to change to the directory
displayed in the text field. (See user preferences Add
to Cache, Diagnostics, Directory Cache Size, Host Cache
Size, and Sort Caches.)
Clear Log (in Log menu)
Clear the diagnostics log window.
Connect to Anonymous (in Connect menus)
Easily connect to an anonymous FTP site. If currently
connected, the connection is first closed. A dialog
pops up to prompt for the remote host, user name and
password. The user name is initialized to "anonymous".
The password is initialized to the value of the user
preference Anonymous Ftp Password (which you will prob-
ably want to set to your email address). An optional
port number may follow the host name (using a space as
the delimiter). Previously used host/user name pairs
are cached, and those with user names "anonymous" or
"ftp" are displayed in a scolled list labeled "Recently
Referenced Hosts:". Double-clicking on a host/user
name pair initiates a connection. Single-clicking on a
host/user name pair places those values in to the host
name and user name fields, where they can be edited.
Click on the Connect button to initiate a connection.
(See user preferences Add To Cache, Anonymous Ftp Pass-
word, Diagnostics, Host Cache Size, User Cache Size,
and Sort Caches.)
Connect to Local (in Connect menus)
Connect to the local (client) host. If currently con-
nected, the connection is first closed. (See user
preferences Left Auto Local Login and Right Auto Local
Login.)
Connect to Remote (in Connect menus)
Connect to a remote host (use Connect to Anonymous to
more easily connect to an anonymous FTP site). If
currently connected, the connection is first closed. A
dialog pops up to prompt for the remote host and user
names. The user name is initialized to the value of the
environment variable USER. An optional port number may
follow the host name (using a space as the delimiter).
Previously used host/user name pairs are cached and
those with user names other than "anonymous" and "ftp"
displayed in a scolled list labeled "Recently Refer-
enced Hosts:". Double-clicking on a host/user name
pair initiates a connection. Single-clicking on a
host/user name pair places those values into the host
name and user name fields, where they can be edited.
Click on the Connect button to initiate a connection.
(See user preferences Add To Cache, Diagnostics, Host
Cache Size, User Cache Size, and Sort Caches.)
Contextual Help (in Help menu)
Enter contextual-help mode. The mouse cursor changes
to a pointing hand. Move the hand and click on any
graphical element in the main window that you wish to
know more about.
Copy (in Xfer Ops controls)
Transfers the selected files according to the mode
(ASCII or Binary) specified in Xfer Mode. A dialog
pops up to enable the user to monitor the progress of
the transfers. The dialog contains a button for abort-
ing the transfers. (See user preferences Beep When Ops
Done, Diagnostics, Initial Transfer Mode, and Inquire
On Copy.)
Delete Selected Entry(s) (in Ops menus)
Deletes the selected entries. A dialog pops up to
enable the user to monitor the progress of the dele-
tions. The dialog contains a button for aborting the
deletions. (See user preferences Beep When Ops Done,
Diagnostics, and Inquire On Delete.)
Deselect All Entries (in Select menus)
Deselect all the entries in the host's current direc-
tory.
Disconnect (in Connect menus)
Close the currently connected host. (See user prefer-
ence Diagnostics.)
Display Directory (Long) (in Dir menus)
Pops up a dialog that displays the contents of the
current directory in a scrollable list. If supported
by the host (and this is almost always the case), addi-
tional information about each directory entry is
displayed, such as file length and access restrictions.
This display is automatically updated as the current
directory changes. This directory display does not
support selecting entries or displaying the current
selection. Warning: Using this feature can increase
network traffic, put an additional load on the remote
host, and slow down interactivity. (See user prefer-
ence Diagnostics and Sort Long Lists By Date.)
Display Directory Path (in Dir menus)
Pops up a dialog that displays the current directory
for that host. It will be automatically updated as the
current directory changes. (See user preference Diag-
nostics.)
Display Directory (Table) (in Dir menus)
Pops up a dialog that displays the contents of the
current directory in tabular form. This dialog may be
used to view and modify the directory's selected
entries. Entries may be selected/deselected either by
clicking or by moving the cursor over the entries with
the mouse button down. Moving the mouse too quickly
can cause some of the entries to be skipped. If an
entry is double-clicked, an attempt is made to change
the current directory to that entry. This display is
automatically updated as the current directory changes.
(See user preference Diagnostics.)
Getting Started (in Help menu)
Describes how to get started using LLNL XFTP.
Go to Previous Directory (in Dir menus)
Displays a pullright menu that allows the user to
easily change the current directory to a previously
referenced directory. (See user preferences Add to
Cache, Diagnostics, Directory Cache Size, Host Cache
Size, and Sort Caches.)
LLNL XFTP Overview (in Help menu)
Gives a high-level description of LLNL XFTP.
Make Directory (in Dir menus)
Pops up a dialog to prompt for the name of a directory
to make in the current directory. The user preference
Enter Dir Upon Creation controls whether the the newly
created directory is automatically entered upon crea-
tion. (See user preferences Diagnostics and Enter Dir
Upon Creation.)
Move Selected Entry(s) (in Ops menus)
Move selected entries from the current directory to
another directory on the same host. This is similar to
the UNIX mv command, but without rename capability.
(See user preferences Beep When Ops Done, and Diagnos-
tics.)
Preferences (in Options menu)
Display the user preferences dialog. See USER PREFER-
ENCES section for a description of user preferences.
Quit (in File menu)
Terminate LLNL XFTP.
Rcopy (in Xfer Ops controls)
Recursively transfers the selected entries according to
the mode (ASCII or Binary) specified in Xfer Mode. If
a selected entry is a directory, an attempt is made to
transfer its entire directory subtree. The user
preference Overwrite Dir On Copy lets the user control
whether or not it is okay to overwrite an existing
directory. A dialog pops up to enable the user to mon-
itor the progress of the transfers. The dialog con-
tains a button for aborting the transfers. (See user
preferences Beep When Ops Done, Diagnostics, Initial
Xfer Mode, Inquire On Copy, and Overwrite Dir On Copy.)
Recursively Delete Selected Entry(s) (in Ops menus)
Recursively deletes the selected entries. A dialog
pops up to enable the user to monitor the progress of
the deletions. The dialog contains a button for abort-
ing the deletions. Warning: Exercise extreme caution
when using this command because it deletes entire
directory subtrees. To minimize the chance of an unin-
tentional deletion, this menu item is greyed out unless
the user preference Recursive Delete Enabled is
enabled. (See user preferences Beep When Ops Done,
Diagnostics, Inquire On Delete, and Recursive Delete
Enabled.)
Rename Selected Entry(s) (in Ops menus)
Pop up a dialog to individually rename selected
entries. This is similar to the UNIX mv command except
that the renamed entries cannot be moved to another
directory. (See user preference Diagnostics.)
Save Log (in Log menu)
Write the contents of the diagnostics window to a
user-specified file. The existing contents of the
diagnostics window are not removed.
Save Preferences (in Options menu)
Save the current settings of the user and viewer
preferences.
Select All Entries (in Select menus)
Select all the entries in the host's current directory.
Send Quoted Command (in Ops menus)
Pops up a dialog to prompt for a "raw" command to send
to the FTP server of the remote host. Previously
issued commands are cached and displayed in a scrolled
list. Double-clicking on a command in the list issues
that command. To have a command act on items selected
in the host's directory list, use the quote placeholder
(which by default is "<>") to represent a selected
item. For example, type "stage 1 <>" to send a STAGE
command to the the remote host for each selected item.
The quote placeholder can changed via the user prefer-
ences. (See user preferences Beep When Ops Done, Diag-
nostics, and Quote Placeholder.)
Use Wildcard (in Select menus)
Pops up a dialog to prompt for a wildcard expression to
use in selecting entries in the host's current direc-
tory list. Previously referenced wildcard expressions
are cached and displayed in a scrolled list. Double-
clicking on an item in the list applies that wildcard
expression. Single-clicking on an item in the list
places the expression in a text field where it may be
edited. Choose the toggle item Replace Filename Selec-
tion to cause the currently selected entries to be
cleared before applying the wildcard. Choose the tog-
gle item Add to Filename Selection to cause the entries
selected by the wildcard to be added to the current
selection. (See user preference Initial Wildcard
Mode).
Using Help (in Help menu)
Gives a description of the online help package.
View (in Xfer Ops controls)
Displays the selected file. The Viewer Preferences
dialog (accessible via the Options menu) can be used to
control whether the file will be displayed using the
built-in viewer or using an external viewer of the
user's choice (e.g., emacs or xv). The selection of
the viewer is configurable, based on the file extension
(e.g., ".gif" or ".jpg"). There is no limit on the
number or types of viewers that can be simultaneously
displayed.
The file is transferred according to the mode (ASCII or
Binary) specified in Xfer Mode. A dialog pops up to
enable the user to monitor the progress of the
transfer. The dialog contains a button for aborting
the transfer.
The destination of the transfer is a temporary direc-
tory created in the directory defined as P_tmpdir in
the include file stdio.h. If the environment variable
TMPDIR is defined, it is used as the directory. The
temporary directory, and the files it contains, are
automatically deleted when the user dismisses the
viewer or terminates LLNL XFTP.
If the file is recognized as being compressed, it is
expanded before viewing. LLNL XFTP excutes the follow-
ing decompressors based on the file extension: gunzip
for ".z" and ".gz"; uncompress for ".Z"; atob for
"atob"; and uudecode for ".uu". LLNL XFTP searches for
the decompressor application in the standard way using
the PATH environment variable.
Viewer Preferences (in Options menu)
Display the viewer preferences dialog. See VIEWER
PREFERENCES section for a description of viewer prefer-
ences.
USER PREFERENCES
Selecting item Preferences in the Options menu pops up a
dialog that allows the user to configure LLNL XFTP according
to his/her preferences. The user is presented with a number
of configuration parameters, which are set by either tog-
gling, sliding, or typing. Click the Apply button to cause
the new values to take effect. The OK button has the same
effect as Apply, but the dialog is also closed. The Cancel
button undoes changes made since OK or Apply were last
pressed. The preferences can be preserved across LLNL XFTP
sessions in a text file named ".xftprc" in the user's home
directory. The user may alter the order the preferences are
presented in the dialog by (1) terminating LLNL XFTP, (2)
using a text editor to change the order of lines in
".xftprc" and (3) restarting LLNL XFTP.
Add To Cache
Specifies whether newly referenced items should be
added to the directory, quoted command, wildcard, and
host/user caches. It is usually desirable to choose
Yes. Choose No if referencing a series of seldom-
referenced items that would clear the cache of your
favorite entries.
Anonymous Ftp Password
The value to initialize the "Password" field of the
Connect to Anonymous dialog to. This is normally your
email address. The Connect to Anonymous dialog is
accessible via each host's Connect menu.
Beep When Ops Done
Specifes whether to beep when each set of deletion,
move, quoted command, and file transfer operations com-
pletes.
Diagnostics
Specifies the level of diagnostics information to be
written to the diagnostics log window. Choose Quiet
for error messages, only. Choose Normal for error mes-
sages and success messages. Choose Verbose for error
messages, success messages, and replies received from
the FTP servers. Choose Debug for error messages, suc-
cess messages, commands sent to the FTP servers,
replies received from the FTP servers, and other
assorted diagnostics.
Directory Cache Size
The maximum number of previously referenced directory
paths cached per host. The cache is preserved across
LLNL XFTP sessions.
Enhance Colors
Speficies whether to "pretty up" some of the graphical
elements (such as scrolled lists and text fields) by
changing the normal background colors. This preference
has no effect on monochrome displays. Choose Yes to
enhance the appearance, or No for the usual Motif look.
Enter Dir Upon Creation
Specifies whether to automatically enter a newly
created directory.
Host Cache Size
The maximum number of hosts to cache items for. The
cache is preserved across LLNL XFTP sessions.
Initial Logfile Name
The default file name to be presented to the user in
the "Save Log" dialog.
Initial Transfer Mode
The default file transfer mode (ASCII or Binary).
Initial Wildcard Mode
The default mode of the "Use Wildcard" dialog. Choose
Replace to make "Replace Filename Selection" the
default. Choose Add to make "Add to Filename Selec-
tion" the default.
Inquire On Copy
Specifies whether to pop up a dialog that asks the user
to confirm that the indicated transfers should take
place.
Inquire On Delete
Specifies whether to pop up a dialog that asks the user
to confirm that the indicated deletions should take
place.
Inquire On Move
Specifies whether to pop up a dialog that asks the user
to confirm that the indicated moves should take place.
Inquire On Quote
Specifies whether to pop up a dialog that asks the user
to confirm that the indicated commands should be sent.
Left Auto Local Login
Specifies whether to automatically connect the left
side to the local (client) host upon starting LLNL
XFTP.
Max Ftp Retries
Specifies the maximum number of retries LLNL XFTP will
attempt if it receives a response from an FTP server
that indicates the desired operation failed because of
some temporary condition on the remote host.
Max Time For Ftp Reply
Specifies the maximum time in seconds that LLNL XFTP
will wait for a response from an FTP server before con-
cluding that the connection has been broken.
Overwrite Dir On Copy
Specifies whether it is okay to overwrite an existing
directory when recursively copying another directory by
the same name. If a sink directory is overwritten then
none of its subdirectories will be deleted, but new
files and subdirectories might be added to it, and some
existing files might be replaced.
Preserve Vms Ver Nums
Specifies whether to preserve VMS file version numbers
when transferring files from a VMS system. This is
only an issue for those VMS FTP servers that provide
numbers (not all do).
Print Password In Debug
Specifies whether to print passwords in the log window
when the user preference Diagnostics is set to Debug.
Quote Cache Size
The number of quoted commands to cache. The cache is
preserved across LLNL XFTP sessions.
Quote Placeholder
This is used as a placeholder in a quoted command to
represent items selected in the directory list. For
example, the quoted command "stage 1 <>" will send a
STAGE command to the remote host for each selected
item. The default value is "<>", but the placeholder
can be set to any nonnull printable string.
Recursive Delete Enabled
Specifies whether to enable the Recursively Delete
Selected Entry(s) item in the Ops menus. Choose No to
help prevent accidental recursive deletions.
Right Auto Local Login
Specifies whether to automatically connect the right
side to the local (client) host upon starting LLNL
XFTP.
Sort Caches
Specifies whether to sort (by ASCII-collating sequence)
cached items when they are displayed in dialogs. If
Yes, then sort. If No, then the most recently refer-
enced items are placed at the top of the list.
Sort Longs Lists By Date
Specifies whether to attempt to sort the "long" direc-
tory lists by time modified (with most recent listed
first) instead of by name. The Yes option is con-
sidered unsafe because some FTP servers to not support
this option and may give unpredictable results. (Most
UNIX hosts support this option.)
Store Unique
Specifies whether existing sink files are to be renamed
before file transfer occurs. If Yes then the existing
sink file is typically renamed by appending a "."
(period) followed by an integer between 1 and 99.
Symbols On Dir Entries
Specifies whether to append single characters to direc-
tory entries in order to distinguish their types. If
Yes(Unsafe) is chosen, "/" is appended to directories,
"*" is appended to executables, "@" is appended to sym-
bolic links, and "=" is appended to AF_UNIX address
family sockets. The "Yes" option is considered to be
unsafe because some FTP servers do not support this
feature and may give unpredictable results. (Most UNIX
hosts support this option.) Furthermore, if you are
referencing a directory or directory entry whose name
ends with one of the special characters, you will need
to select No(Safe). When in doubt, select No(Safe).
One further note: use of this feature can dramatically
degrade interactivity.
Use Last Dir At Login
Specifies whether to automatically enter the most
recently referenced directory after connecting to a
host. If this option is requested, but is not possible
to perform (e.g., because the directory no longer
exists), an error message will be generated, and your
home directory will be entered. Note: This mechanism
attempts to enter the last directory referenced on the
host, regardless of whether it is another user's direc-
tory.
User Cache Size
The number of user names to cache (for remote hosts).
The cache is preserved across LLNL XFTP sessions.
Wildcard Cache Size
The number of wildcard expressions to cache. The cache
is preserved across LLNL XFTP sessions.
VIEWER PREFERENCES
Selecting item Viewer Preferences in the Options menu pops
up a dialog that allows the user to control which file will
be displayed with which viewer, based on the file extension.
A file to be viewed is first transferred to a temporary
directory and then, if necessary, is decompressed. The file
extension (e.g., ".gif") is then examined to determine which
viewer the file is to be displayed in. There are two types
of viewers: the viewer built into LLNL XFTP (which is suit-
able for displaying text files) and external viewers (e.g.,
emacs for text and xv for graphics).
Single-click on an entry in the Extensions list to place
that extension and its associated command line into the
Extension and Viewer Command Line text fields, respectively.
An extension is a file suffix that begins with a period
("."). A special entry in the extensions list, "OTHERS"
represents all files that do not have their extension listed
(including files with no extensions).
The pattern "<>" in a command line is a placeholder for the
name of the file to be viewed. A blank command line indi-
cates that the built-in viewer is to be used. To add a new
extension to the list, fill in the Extension and Viewer Com-
mand Line text fields and press the Add button. If the text
in Extension does not begin with a period, one will be
added. If the extension is already in the list, it will be
replaced.
To replace the command line associated with an extension,
(1) single-click on the list item to select it, (2) edit the
command line, and (3) press the Replace button.
To delete an extension from the list, single-click on the
list item to select it and then press the Delete button.
The "OTHERS" entry cannot be deleted (but it's command line
can be replaced).
Click the Apply button to cause the new changes to take
effect. The OK button has the same effect as Apply, but the
dialog is also closed. The Cancel button undoes the changes
made since OK or Apply were last pressed.
The viewer preferences can be preserved across LLNL XFTP
sessions in a text file named ".xftpview" in the user's home
directory (select Save Preferences in the main window's
Options menu).
LIMITATIONS
Here are some things to watch out for:
LLNL XFTP might not work with some old X servers. For exam-
ple, some older OpenWindows servers might dump core. MacX
fans should use nothing older than version 1.1.7b.
Old, buggy versions of Motif can cause weirdness.
LLNL XFTP might not work correctly with some non-Unix FTP
servers. (If you can give us temporary access to such a
server, we might be able to fix the problem.)
Out-of-spec FTP servers can cause untold grief. (Most
Unix-based servers work correctly.)
Third-party file transfers will not work unless at least one
of the remote FTP servers supports the PASV (passive) com-
mand.
