Hi,

A very heuristic thing, as it seems:

  https://linux.die.net/man/8/unhide-tcp
  "unhide-tcp is a forensic tool that identifies TCP/UDP ports that
   are listening but are not listed in /bin/netstat through brute
   forcing of all TCP/UDP ports available."

This raises the question why netstat does not show Rob's NFS ports.
Does NFS change the port fast enough so that netstat and port scan differ ?


Have a nice day :)

Thomas
