eisvogel has asked for the wisdom of the Perl Monks concerning the following question:

How to use IPC::Run (with <pty redirect operator) and the batch-mode run routine to execute the ssh1 client, so that can write its stdin and read its stdout and stderr, as handles?

    The Net::SSH module looks as if it might be useful.

    For some reason, if we start ssh directly, ssh doesn't accept these ptys (and tries to launch ssh askpass). But if we start bash first, and from there launch ssh, it works.

        my $h = start ['bash'], '<pty<', \$in, '>pty>', \$outAndErr, timeo
+ut(15);
    pump $h until $outAndErr =~ /$prompt/;
    $outAndErr='';
    $in .= "ssh user\@host\n";
    pump $h until $outAndErr =~ /password:/;
    $outAndErr='';
    $in .= "password\n";
    pump $h until $outAndErr =~ /$remotePrompt/;
    $outAndErr='';
    # You're in - do your stuff

    Disclaimer: The original version of the above snippet works, but I've simplified it for this posting, and it is possible there are (minor) bugs in the above.
