Seems there is certainly yet another hoop to jump as a result of. Open up your SSH config file by managing nano ~/.ssh/config and include the following:
Thus it is not sensible to educate your end users to blindly take them. Changing the keys is So either most effective performed employing an SSH important administration Device that also modifications them on clients, or working with certificates.
