You can paste or import public SSH keys from remote hosts as a convenience, so 
that you do not get prompted to accept a new key during later use of SCP or SFTP 
for file or data transfer. 

To achieve strict “man in the middle” protection, verify the fingerprint before 
applying the changes.

To manage the public SSH keys of known remote hosts, use the following 
command:

The SSH Known Host Keys menu displays.

The SSH Known Host Keys menu includes the following options:

Enter an elllipsis (

) to signal the end of the key.

Valid formats are as described for the 

 command or the 

native format used by the OpenSSH implementation.

If the key has a valid format, you will be prompted for 
the corresponding host name or IP address. You can 
provide a comma-separated list of names and 
IP addresses for the host.

The system automatically assigns the next available 
index number to the known host SSH key.

import <IPaddr>

Allows you to import an SSH key from a remote host.

•

IPaddr

 — the IP address of the remote host
