Hello Monks, and Happy Holidays!

First off..thanks to any who try to help me. :) I do appreciate it.

The goal: To go out and query our 'lightwaves' (I am a UNIX admin, and lightwaves are stripped-down linux boxes connected to the serial ports of our servers, to give us a remote console)for server/port information. Hard to believe, as of now, we don't have records and we work in a VERY LARGE ENVIRONMENT.

The tools: Hopefully, Perl's Expect.pm.

The drawback: I do not know Expect; I have chosen Perl's Expect module because I am adequate in Perl (although by no means and expert) and am learning more.

The problem: The documentation I've read is like mud to me, which , I guess, is because I don't know Expect and have never played around with pty's, etc.

I can spawn a ssh process, and issue commands to it, but I'm stuck on figuring out how to capture the output.

My ask is two-fold: 1) Does anyone know of a good source to read about using Expect.pm?

2) Given the code snippet below, can anyone guide me on how to capture the output of the 'listdev' command I issued on the lightwave? (plycon1 ). That is the part where I'm running into trouble.

($ssh = Expect->spawn("ssh -l sysadmin  $server")) || die "couldn't sp
+awn ssh: $!";

unless ($ssh->expect(10,"password")) {
        die "never got username prompt on $server, " .ssh->exp_error()
+,"\n";
        }
print $ssh "$password\r";

unless ($ssh->expect(10,"sysadmin>")) {
        die "never got sysadmin prompt on $server, " .ssh ->exp_error(
+),"\n";
        }

print $ssh "listdev\r";
