+#!/bin/bash
+
+# Verify that it is possible to SSH to a public address after disabling a node.
+
+# We SSH to a public IP and check the hostname, disable the node hosting
+# it and then SSH again to confirm that the hostname has changed.
+
+# 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.
+
+# Steps:
+
+# 1. Verify that the cluster is healthy.
+# 2. Select a public address and its corresponding node.
+# 3. SSH to the selected public address and run hostname.
+# 4. Disable the selected node.
+# 5. SSH to the selected public address again and run hostname.
+
+# Expected results:
+
+# * When a node is disabled the public address fails over and it is
+#   still possible to SSH to the node.  The hostname should change.
