Solution Verified - Updated -

Issue

  • Can a bastion host (or proxy / jump host) be clustered in order to be used securely in a high availability context?
  • How can I avoid man-in-the-middle warnings from ssh when a virtual IP switches from one node to another?

Environment

  • Red Hat Enterprise Linux (RHEL)
  • OpenSSH (ssh)
