reset and Data::Dumper

whereiskurt has asked for the wisdom of the Perl Monks concerning the following question:

Dearest Monks,

This must happen to other people ... maybe I'm just showing my noobness. :-)

...
  my $ether_data = NetPacket::Ethernet::strip($packet);
  my $ip = NetPacket::IP->decode($ether_data);
  my $tcp = NetPacket::TCP->decode($ip->{'data'});
 
  print Dumper($ip);
  print Dumper($tcp);

As I run this little script in bash, inevitably the characters set starts to display real bizzare and nothing looks normal. [Kind of reminds of a DOS ANSI bomb.] Eventually I end up typing 'reset', which looks more like a bunch of pipes and bars. I'm not sure exactly what's happening, but I believe it has something to do with "binary" data.

Any advice on how to prevent/mitigate this would be appreciated. I hope this is considered on topic.

Kurt

ikegami, Friggin' right! Thanks for the help. The keyword I now know is "unsafe characters." Kurt	[reply]
