ACB (autoconfig backup) and router image files



  • Hello,

    So from my understanding, the ACB uses some kind of identifier to generate the ACB key for the router.

    If we wanted to keep a router image (like a VM, or an XML file) to deploy to multiple different routers for multiple different clients, how to we change the ACB key for each image we install?

    We have tried with a VM image in the lab and each one we spin up, has the same ACB key as its based off the image some how.

    Is there a script to run to generate a new key or some setting we can change to force a new key creation?

    Like it says on the ACB configuration page, it is derived from the generated ssh key. The ssh key is generated uniquely for every installation.

    Probably uncheck ssh, rm /etc/ssh/*.key /etc/ssh/*.pub then re-enable ssh. A new key should be generated.

    Or just disable ssh and remove those files and use that as your snapshot. Then a new key will be generated when/if ssh is enabled.

    I didn't test any of this but that is the kind of thing I would expect to work for you.
