Migrating or Recovering a Cloudvue Tunneling Machine

Description

Use the following instruction to recover your tunneling machine or migrate  to a new one

Assumptions

  • Your old tunneling machine was configured and working
  • You know the hostname of your old tunneling machine
  • You have a copy of the following files from your old tunneling machine
    • ~/.ssh/id_rsa
    • ~/.ssh/id_rsa.pub

Solution

  • Create a new tunneling Machine
  • See KB#13051 “Cloudvue SSH Tunneling” for instructions and recommendations
  • Copy both of these files from the old tunneling machine onto the new one
    • ~/.ssh/id_rsa
    • ~/.ssh/id_rsa.pub
  • Change the hostname of the new tunneling server to match the hostname of the old tunneling server

Example

Display hostname

$ hostnamectl

Pro Tip:  Quick recovery hinges on you having a backup of both, id_rsa and id_rsa.pub , and a record of the hostname of your tunneling machine
