+# pingtest.sh, v1.0.1
+# Created 2009 by Bennett Lee
+# Released to public domain
+#
+# (1) Attempts to ping several hosts to test connectivity.  After
+#     first successful ping, script exits.
+# (2) If all pings fail, resets interface and retries all pings.
+# (3) If all pings fail again after reset, then reboots pfSense.
+#
+# History
+# 1.0.1   Added delay to ensure interface resets (thx ktims).
+# 1.0.0   Initial release.
+#=====================================================================
+
+#=====================================================================
+# USER SETTINGS
+#
+# Set multiple ping targets separated by space.  Include numeric IPs
+# (e.g., remote office, ISP gateway, etc.) for DNS issues which
+# reboot will not correct.
