I want to be able to retrieve values from an embedded device every minute. Currently I have a script that does this over ssh but I have to type in the password for the embedded device every time I connect to it over SSH. The embedded device is read only and there is absolutely no way I can mount it as writeable at this time. The embedded device is configured badly so I can't even temporarily upload the id_rsa.pub of my machine to the embedded device to allow me to automatically connect using public key authentication. The other problem is I can also not use the "expect" keyword or sshpass daemon since I can't install software on the embedded device.
I forgot to say there is another read only embedded device between me and the embedded device with the data on.
Is there any hope for me? Thanks for your time.
