Stricthostkeychecking variable. By default, Stricthostkeychecking = Ask. The three configuration values are as follows:1. Stricthostkeychecking = No# The most insecure level. Of course, there are not so many annoying prompts. We recommend that you use it for relatively secure Intranet testing. If the key connecting to the server does not exist locally, it is automatically added to the file (known_hosts by default) and a warning is given.2. Stricthostkeychecking = ask # The default level.
