Configures global SSH client settings.
The no form of the command negates global SSH client settings.
Syntax Description host-key-check <policy> Sets SSH client configuration to control how host key
checking is performed. This parameter may be set in 3
ways.
• If set to “no” it always permits connection, and accepts
any new or changed host keys without checking
• If set to “ask” it prompts user to accept new host keys, but
does not permit a connection if there was already a known
host entry that does not match the one presented by the
host
• If set to “yes” it only permits connection if a matching
host key is already in the known hosts file
known-host Adds an entry to the global known-hosts configuration
file.
known-host-entry Adds/removes an entry to/from the global known-hosts
configuration file. The entry consist of “<IP> <key-
type> <key>”.
Default host-key-check - ask, no keys are configured by default
