In beginning to migrate to RHEL 9, you may find that when you try to ssh to a RHEL 9 system you get complaints about your ssh key or the key length. This is due to your key being created many years ago and RHEL 9 being a bit more restrictive. If you run into
problems, you can run the restore_default_ssh script to backup and recreate your .ssh keys with newer and larger key-length. This script can be executed (it will ask you for confirmation) from the command line or from the "restore utility" from Jmenu.</div>
