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.
