did a little more research ... it appears nidump makes a query to portmap to look for netinfobind if either of these are not listening the use of a remote tag with nidump or nireport may fail. A vulnerable machine should have the following open. program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 200100001 1 udp 796 netinfobind 200100001 1 tcp 799 netinfobind -KF
