#!/bin/bash
# Verify that CIFS connections are monitored and that CIFS tickles are sent.
# We create a connection to the CIFS server on a node and confirm that
# this connection is registered by CTDB. Then disable the relevant CIFS
# server node and ensure that the takeover node sends an appropriate
# reset packet.
# Prerequisites:
# * An active CTDB cluster with at least 2 nodes with public addresses.
# * Test must be run on a real or virtual cluster rather than against
# local daemons.
# * Test must not be run from a cluster node.
# * Clustered Samba must be listening on TCP port 445.
# Expected results:
# * CTDB should correctly record the connection and the takeover node
# should send a reset packet.
