   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 it send an appropriate reset packet.
  11
  12 Prerequisites:
  13
  14 * An active CTDB cluster with at least 2 nodes with public addresses.
  15
  16 * Test must be run on a real or virtual cluster rather than against
  17   local daemons.
  18
  19 * Test must not be run from a cluster node.
  20
  21 * Clustered Samba must be listening on TCP port 445.
  22
  23 Steps:
  24
  25 1. Verify that the cluster is healthy.
  26 2. Connect from the current host (test client) to TCP port 445 using
  27    the public address of a cluster node.
  28 3. Determine the source socket used for the connection.
  29 4. Using the "ctdb gettickle" command, ensure that CTDB records the
  30    connection details.
  31 5. Disable the node that the connection has been made to.
  32 6. Verify that a TCP tickle (a reset packet) is sent to the test client.
  33
  34 Expected results:
  35
  36 * CTDB should correctly record the connection and should send a reset
  37   packet when the node is disabled.
