Your first sample works for me:
use Net::Telnet;
my $telnet = Net::Telnet->new(Timeout => 10);
$telnet->dump_log("dump.log");
$telnet->open("machine");
$telnet->login("user", "oass");
$telnet->close;
I get a bunch of stuff (the stuff that goes in and out over the
telnet connection) in dump.log. Are you actually trying to open
a connection? I doubt you'll get anything in your dump_log
file if you don't *do anything*. :)
Oh, and your second snippet is wrong. That's not a filehandle;
that's a diamond-operator *read* from a filehandle. STDOUT
is the filehandle, <STDOUT> is you reading from the
filehandle. You want
$telnet->dump_log(*STDOUT);
