.Sh NAME
.Nm gnome-ssh-askpass
.Nd prompts a user for a passphrase using GNOME
.Sh SYNOPSIS
.Nm Op Ar message ...
.Sh DESCRIPTION
.Nm
is a GNOME-based passphrase dialog for use with OpenSSH.
It is intended to be called by the
.Xr ssh-add 1
program and not invoked directly.
It allows
.Xr 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
.Xr ssh-add 1
is invoked from one's
.Pa ~/.xsession
or as one of the GNOME startup programs, for example.
.Pp
In order to be called automatically by
.Xr ssh-add 1 ,
the
.Ev SSH_ASKPASS
environment variable should be set to point to the location of
.Nm ,
or
.Nm
should be installed as
.Pa /usr/bin/ssh-askpass .
.Sh ENVIRONMENT
The following environment variables are recognized:
.Bl -tag -width "GNOME_SSH_ASKPASS_GRAB_POINTER"
.It Ev GNOME_SSH_ASKPASS_BG_COLOR
Text area background color, specified as hexadecimal RGB or RRGGBB,
optionally prefixed by
.Dq #
or
.Dq 0x .
.It Ev GNOME_SSH_ASKPASS_FG_COLOR
Text area foreground color, specified as hexadecimal RGB or RRGGBB,
optionally prefixed by
.Dq #
or
.Dq 0x .
.It Ev GNOME_SSH_ASKPASS_GRAB_POINTER
If set, causes
.Nm
to grab the mouse pointer before asking for a passphrase.
.It Ev GNOME_SSH_ASKPASS_GRAB_SERVER
If set, causes
.Nm
to grab the X server before asking for a passphrase.
.It Ev SSH_ASKPASS_PROMPT
If set to
.Li confirm ,
show a yes-or-no prompt, defaulting to yes.
If set to
.Li none ,
show a prompt with only a close button.
Otherwise, show an OK-or-cancel prompt, defaulting to OK.
This environment variable is typically set by
.Xr ssh-add 1 ,
and should not normally be set manually.
.El
.Pp
Regardless of whether either
.Ev GNOME_SSH_ASKPASS_GRAB_POINTER
or
.Ev GNOME_SSH_ASKPASS_GRAB_SERVER
is set,
.Nm
will grab the keyboard.
