Porter,
Can you explain a bit in detail?

GNOME-SSH-ASKPASS(1)					      General Commands Manual					      GNOME-SSH-ASKPASS(1)

NAME
gnome-ssh-askpass - prompts a user for a passphrase using GNOME SYNOPSIS
gnome-ssh-askpass DESCRIPTION
gnome-ssh-askpass is a GNOME-based passphrase dialog for use with OpenSSH. It is intended to be called by the ssh-add(1) program and not invoked directly. It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display is available). This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro- grams, for example. In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass. ENVIRONMENT VARIABLES
The following environment variables are recognized: GNOME_SSH_ASKPASS_GRAB_SERVER Causes gnome-ssh-askpass to grab the X server before asking for a passphrase. GNOME_SSH_ASKPASS_GRAB_POINTER Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase. Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab(). AUTHOR
This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others). It was based on that for x11-ssh-askpass by Philip Hands. GNOME-SSH-ASKPASS(1)
