.SH NAME
.PP
ssh\-askpass\-noinput \- an \f[C]ssh\-askpass\f[] implementation for
asking allow/deny questions
.SH SYNOPSIS
.PP
\f[I]ssh\-askpass\-noinput\f[] text
.SH DESCRIPTION
.PP
\f[I]ssh\-askpass\-noinput\f[] is an implementation of
\f[I]ssh\-askpass\f[], which does not acutally ask for a password;
instead, it only asks a binary (allow/deny) question and exits with 0
for allow and 1 for deny.
.PP
It is not intended as a general replacement for \f[I]ssh\-askpass\f[],
but for special applications that don\[aq]t care about a passphrase.
.SH OPTIONS
.PP
As usual with \f[I]ssh\-askpass\f[] implementations,
\f[I]ssh\-askpass\-noinput\f[] only takes a single argument, which will
be presented as the question.
.SH BACKGROUND AND APPLICATIONS
.PP
Some programs (\f[I]ssh\-agent\f[] and \f[I]ssh\-agent\-filter\f[]) use
\f[I]ssh\-askpass\f[] to have users confirm actions without entering a
passphrase; \f[I]ssh\-agent\f[] does this when used via
\f[I]ssh\-add\f[]\[aq]s \f[C]\-c\f[] option.
They do not indicate that it is a binary question (because in the
classical \f[I]ssh\-agent\f[] invocation, there is no option to do
this), and expect the user to ignore the text input and click "OK" or
"Cancel", whereupon they read the askpass\[aq]s exit status.
.PP
With programs that are known to only ask those questions, setting
\f[C]SSH_ASKPASS=ssh\-askpass\-noinput\f[] in their environment will
make them use this particular implementation for their questions.
It should never be installed as \f[C]/usr/bin/ssh\-askpass\f[].
.SH FUTURE
.PP
This solution is obviously a hack, which is needed until a way is
established and implemented for \f[I]ssh\-askpass\f[] to be used more
flexibly.
