NAME

       ssh-askpass-noinput - an ssh-askpass implementation for asking allow/deny questions

SYNOPSIS

       ssh-askpass-noinput text

DESCRIPTION

       ssh-askpass-noinput is an implementation of ssh-askpass, 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.

       It  is not intended as a general replacement for ssh-askpass, but for special applications
       that don't care about a passphrase.

OPTIONS

       As usual  with  ssh-askpass  implementations,  ssh-askpass-noinput  only  takes  a  single
       argument, which will be presented as the question.

BACKGROUND AND APPLICATIONS

       Some  programs  (ssh-agent  and  ssh-agent-filter)  use  ssh-askpass to have users confirm
       actions without entering a passphrase; ssh-agent does this  when  used  via  ssh-add's  -c
       option.   They  do  not  indicate  that  it is a binary question (because in the classical
       ssh-agent 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's exit status.

       With    programs    that    are    known    to   only   ask   those   questions,   setting
       SSH_ASKPASS=ssh-askpass-noinput in their environment will make them  use  this  particular
       implementation for their questions.  It should never be installed as /usr/bin/ssh-askpass.

FUTURE

       This  solution  is  obviously  a  hack,  which  is  needed  until a way is established and
       implemented for ssh-askpass to be used more flexibly.
