Description: Hi there. I have a fairly simply task; I just want
to use the IPC::Run module (with <pty redirect operator)
and the batch-mode run routine to execute the ssh1 client,
so that I can write by handle to its stdin and read (by
handle) from its stdout and stderr. Does anyone know of
any good code somewhere to do this, or any code that uses
IPC::Run with ptys to execute anything?
Many thanks!
Answer: Using IPC::Run to control ssh client
contributed by lachoy The Net::SSH module looks
as if it might be useful. | Answer: Using IPC::Run to control ssh client
contributed by Lightknight 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
