Your code bears little relation to the documentation of Net::SNMP. First of all there is no 'DestHost' parameter to the the session method, and I think you should be calling my $session = new SNMP::Session(-hostname => $host); (The version and community default to SNMPv1 and public, respectively) Also there is no get method and I am surprised your code runs. Perhaps you should write my $result = $session->get(-varbindlist => [$oid]); but I have no way of testing this code.
