 FreshTomato includes [[https://matt.ucc.asn.au/dropbear/dropbear.html|Dropbear]], an SSH client/server program. Dropbear can generate a 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 Administration/[[:admin_access|Admin Access]] menu.\\ This allows command-line management of the secondary router (or "SSH Host") from a primary router, (the "SSH Client"). This can be useful when the system clock is not maintained in the secondary router and time-sensitive jobs must be scheduled. For example, as seen below, it may be useful to switch wireless radio(s) on or off to a schedule (not shown). It could also be used to run scripts on the target for any supported command. FreshTomato includes [[https://matt.ucc.asn.au/dropbear/dropbear.html|Dropbear]], an SSH client/server program.
