Contents of README:# README: Notes about X11-based passphrase dialog for OpenSSH # created 1999-Nov-21 jmk # autodate: 2001-Feb-14 04:07 +-------------+ | Description | +-------------+ This is an X11-based passphrase dialog for use with OpenSSH. It is intended to replace the Perl/Tk-based ssh-askpass dialog and GNOME-based ssh-askpass dialog which formerly accompanied OpenSSH-1.2. These dialogs are intended to be called from the ssh-add program and not invoked directly. The features of x11-ssh-askpass are as follows: - Configurable via the standard X resource mechanism (/usr/lib/X11/app-defaults, ~/.Xdefaults, xrdb, etc.). - Require only stock X11 libraries (libXt, libX11, libSM, libICE). - Can be configured to grab the keyboard and/or pointer (grabs the keyboard by default, not the pointer). The user interface is somewhat different than most password/passphrase dialogs and more similar to the X11-based passphrase dialog that accompanies the regular SSH distribution. Instead of a text field that fills with asterisks or some other character as the user enters the passphrase, a series of LED-like areas light up one-by-one with each passphrase character entered, beginning from the lefthand edge of the dialog. When they reach the righthand edge, they go dark one-by-one again, and so on. This gives the user feedback that passphrase characters have been entered, but does not provide onlookers with a cue as to the length of the passphrase. Pressing the `OK' button accepts the passphrase (even if it is empty), which is printed on the standard output, and the dialog exits with a status of zero (success). Pressing the `Cancel' button discards the passphrase, and the dialog exits with non-zero status. The following keystrokes work as expected: [Backspace] or [Delete] Erase previous character [Control+U] or [Control+X] Erase entire passphrase [Enter], [Control+M], or [Control+J] Accept passphrase (OK) [Escape] Discard passphrase (Cancel) +------------+ | Installing | +------------+ x11-ssh-askpass currently uses imake and xmkmf to build. Here's the procedure: xmkmf make includes make make install make install.man x11-ssh-askpass installs by default in /usr/local/libexec/openssh/. To install it somewhere else (for example, /usr/libexec/openssh/) use: make install BINDIR=/usr/libexec/openssh Several different app-defaults files accompany x11-ssh-askpass: SshAskpass-1337.ad - small, dark, and gray SshAskpass-NeXTish.ad - a look mildly similar to that of NEXTstep SshAskpass-default.ad - the default look SshAskpass-green.ad - somewhat green SshAskpass-motif.ad - a bit like the look of the Motif toolkit If you wish a look other than the default, perform the following commands before building (for example): rm -f SshAskpass_ad.h make includes APP_DEFAULTS=SshAskpass-NeXTish.ad +-----------------+ | Where To Get It | +-----------------+ x11-ssh-askpass is available at: http://www.jmknoble.cx/software/x11-ssh-askpass/ +--------------------------+ | Copyright, License, Etc. | +--------------------------+ Some portions of x11-ssh-askpass are derived directly or indirectly from portions of xscreensaver by Jamie Zawinski <jwz@jwz.org>, while others are original works.
