FreshTomato includes Dropbear, an SSH client/server program. Dropbear can generate an encryption KeyPair that offers password-less connections. A command is run on the primary router which generates a public key. That Public Key must then be pasted into the secondary router’s Authorized Keys field, in the SSH Daemon section of the Admin Access menu.
This setup allows a primary router, (the “SSH Client”) to control a secondary router (the “SSH Host”), from the command-line.
This can be useful, for example:
Note that a pre-existing, and unrelated key is redacted above.
This example will enable/disable the eth1 5Ghz Wi-Fi interface on the secondary router. (Temperature is shown only when the interface is on).
If the same command is repeated, the eth1 interface will be disabled on the primary router.
