Information in this document applies to any platform.
Symptoms
- An application or SFTP/SSH client reports random key changes when connecting to a SFTP/SSH server.
- The SFTP/SSH server is actually two or more servers hosted behing a load-balancer. The application or SFTP/SSH client connects to the load-balancer
- Checking the SSH server host keys inside /etc/ssh/ for each singe SFTP/SSH server shows that the host keys have not been modified.
- There is no acceptable way to configure the application or SFTP/SSH clients to silently accept multiple host keys from the same server (and doing so is a serious security concern in any case).
