I didn't see anything that seemed to be a show stopper however I thought this line looked a little odd
$params{'debug'} = 'true';

Usually I see this when creating a connection and debugging the session 
 my $ssh = Net::SSH::Perl->new($srvr, protocol => 2, debug => 1);

Maybe I'm just being picky. Perhaps you can try spelling it out like this and see if it helps. Are you receiving any debug information? If so could you please provide it. Also you could simplify this

my (my $stdout, my $stderr, my $exit2) = $ssh->cmd('ls -l');

with this 
my ($stdout, $stderr, $exit2) = $ssh->cmd('ls -l');

Just some thoughts that might help. And don't forget the debug info.
