+For various reasons, you might want to monitor your Internet connectivity. The simplest way to do this is to run a custom task script. The basic command structure might look something like this:
-The besic command would be something like:
+For example, in the [[admin-sched|Scheduler]] menu, in the** **//Custom 1 field://
-**/****bin/ping -q -c1 8.8.4.4**
+ \\
-(8.8.4.4. being the a google DNS) which would cover the monitoring part without perform any action.
+<code ->
+/bin/ping -q -c1 8.8.4.4
+</code>
-To link an action to success (&&) or failure (||) or both append the wanted condition + command
+\\ The 8.8.4.4. IP address is a google DNS server. This scheduled command would allow monitoring without requiring any further interaction with the user.
-Examples:
+Next, in order to link an action to a success (&&) or failure (||) , we will append a command to the wanted condition.
-**/bin/ping -q -c1 8.8.4.4 || /sbin/service wan restart** #if ping fails restart the wan
+ \\
-**/bin/ping -q -c1 8.8.4.4 || /sbin/reboot** # if ping fails reboot the device
+For example:
+ \\
+ \\
+<code ->
+#if ping fails, restart the wan.
+/bin/ping -q -c1 8.8.4.4 || /sbin/service wan restart
-**/bin/ping -q -c1 8.8.4.4 && /usr/bin/logger "Internet available" || /usr/bin/logger "Internet unavailable"** # successful ping will log "Internet Available" where ping failure logs "Internet unavailable"
+# if ping fails, reboot the device.
+/bin/ping -q -c1 8.8.4.4 || /sbin/reboot
-etc
+# successful pings will log "Internet Available" where ping failures will log "Internet unavailable".
+/bin/ping -q -c1 8.8.4.4 && /usr/bin/logger "Internet available" || /usr/bin/logger "Internet unavailable"

+===== Connectivity Watchdog Notes =====
+This script is a custom one. Please note that there is also a setting in FreshTomato's [[basic-network|Network]] Web interface menu called "//Check Connections Every//". This feature performs similar functions, with some differences. It is not recommended that you use both this watchdog script and the //Check Connections Every //function at the same time. The two functions may interfere with each other, and conflicts might occur.
