+For external IP address management, verify that CIFS tickles are sent.

+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.
