   6 Verify that CIFS connections are monitored and that CIFS tickles are sent.
   7
   8 We create a connection to the CIFS server on a node and confirm that
   9 this connection is registered by CTDB.  Then disable the relevant CIFS
  10 server node and ensure that the takeover node sends an appropriate
  11 reset packet.
  12
  13 Prerequisites:
  14
  15 * An active CTDB cluster with at least 2 nodes with public addresses.
  16
  17 * Test must be run on a real or virtual cluster rather than against
  18   local daemons.
  19
  20 * Test must not be run from a cluster node.
  21
  22 * Clustered Samba must be listening on TCP port 445.
  23
  24 Expected results:
  25
  26 * CTDB should correctly record the connection and the takeover node
  27   should send a reset packet.
