Dear PerlMonks,

I've been loving Net::SSH2 and have been using it for a few months. It's much easier to install (less dependancies than Net::SSH::Perl) and overall it's faster when hitting our remote servers. I've been working with the Net::SSH2 forum however they seem to have problems with their server lately. I'm hoping someone here might have some insights to help me along my way.

The Question/Problem

I'm trying to pull STDERR from my remote server. The idea is we want to trigger a subroutine to execute when STDERR traffic is detected. In the past I simply called the NET::SSH::Perl method register_handler. Here is how I used to do it 
   &register_handler("STDERR", sub {
                  my($channel, $buffer) = @_;
                  print "** STDERR -- I received this: ", $buffer->byt
+es;
                      });

Dave Robins (the developer) mentioned I check out the POLL method to do something similar to this however I must be missing something. I've read perldoc however I'm not seeing where to call the subroutine from POLL. Here is the module I'm using Net-SSH2-0.09

Here is how I'm trying to call it:

# Create the ssh2 object
   my $ssh2 = Net::SSH2->new();

# Create my STDERR trigger
   my $poll=Net::SSH2->poll( 1, 'pollerr');

# connect to remote server
   $ssh2->connect($server) or die "** Failed to connect via Net::SSH2:
+ $!\n";
      print "**  Connect to server $server successful\n\n";

I've tried replacing 'pollerr' with STDERR and stderr. In both cases I get a message stating I can't use symbolic references. Only hard references are allowed.

Has anyone been successful in doing this? I'm also curious how I could use POLL to execute a subroutine when STDERR traffic is detected.

I've also tried using Net::SSH::Channel and calling the read method to read STDERR. It runs fine however nothing is captured when I run my sudo command. I've even tried the above against STDOUT just to see if I'm getting anything. No dice.

What else can I tell you about my situation?

Thanks a bunch!
