Hi, I never used it myself, but the docs for the module show you can get a $pid for the connection. 
 # various ways of starting a connection returning a $pid
 my ($in, $out ,$pid) = $ssh->open2("foo");
 my ($pty, $pid) = $ssh->open2pty("foo");
 my ($in, $out, $err, $pid) = $ssh->open3("foo");
 my ($pty, $err, $pid) = $ssh->open3pty("login");

I would say you could either issue 
kill 9, $pid;

#or in case some shells are hiding in there ( which may cause defunct process) 
use Proc::Killfam;
killfam 9, $pid

See Stopping subprocesses for a discussion of this. As a last resort, you can always search the process table for your process name, get the pid and kill it. Changing $0 of your script would make it easier to find in the process table, like 

$0 = 'rastoboy-ssh'; # :-)
