this is a snippet from a child process ( the $to_parent is an already-defined IO::Socket object that sends info back to the parent process for data collection ). i'm consistently getting 'Permission Denied' errors - which is fine, because I want to trap errors also - but they're printed to STDOUT, and not captured in the read filehandle passed into open3. am i missing something obvious? mininal code sample 

my $writer = IO::Handle->new();
my $reader = IO::Handle->new();

eval {
     my $cpid = open3( $writer, $reader, $reader, "rsh $name show hard
+serial" );
};

print $to_parent "ERROR::$name--refused RCP command\n" if ( $@ =~ /ope
+n3/ );

my $return_val = <$reader> ;
chomp $return_val;

#for debugging
print STDOUT "RETURNED:  $return_val\n";

print $to_parent "RESULTS::RCP:$name--RCP Successful\n" if ( $return_v
+al );
