+=====  Setting up/Establishing a Tunnel =====
 Follow these steps to generate a Keypair and establish an SSH tunnel:
-  - On the primary router (the one issuing SSH commands) generate a Keypair by typing the command: \\ "dropbearkey -t rsa -f ~/.ssh/id_dropbear" \\ \\ This will display a result similar to that shown below. Leave this window open, as you'll need it for step 2. \\ \\ \\ {{:pasted:20210921-152323.png}} \\ \\

Leave this window open, as you'll need it for step 2. \\ \\ {{:pasted:20210921-152323.png?744}} \\ \\
-  - Copy the Public key portion from the primary router and paste it into the “Authorized Keys” field in secondary router: \\ \\ {{:pasted:20210921-152415.png}} \\ \\

-  - Note that a pre-existing, and unrelated key was redacted above. \\ \\
+  - In the above screenshot, a pre-existing, unrelated key was redacted. \\ \\
-  - Now, connect to the secondary router via an SSH session (running on the primary router). The example below uses the //nvram// command to display the hostname. The first command string ("ssh root@192.168.10.1 nvram get lan_hostname")** **executes the command on the secondary router and then it [nvram get lan_hostname] is executed locally, on the primary router. \\ \\ \\ {{:pasted:20210921-152503.png}}

+===== Usage Example =====
 This example will enable/disable the eth1 5Ghz WiFi interface on the secondary router. (Temperature is shown only when the interface is enabled).  \\  \\

+  - This screenshot shows the status display of the Primary router before before the command is run: \\ \\ {{:pasted:20210921-152542.png?736}} \\ \\
-  - Now, we run the command (//ssh root@192.168.10.1 radio toggle 1//): \\ \\ {{:pasted:20210921-152607.png}} \\
+  - Now, we run the command (//ssh root@192.168.10.1 radio toggle 1//): \\ \\ {{:pasted:20210921-152607.png?744}} \\ \\
-  - This shows the status display after the command is run: \\ \\ {{:pasted:20210921-152637.png}} \\  \\ If the same command is repeated, the eth1 interface will be disabled on the primary router.
+  - This shows the status display after the command is run: \\ \\ {{:pasted:20210921-152637.png?761}} \\  \\ Since "radio toggle 1" is  a toggle switch, if the same command is repeated, the eth1 interface will be disabled on the primary router.
