clear known_hosts [< ip-address> ]
D
ESCRIPTION
This command enables you to clear the address key mapping for all the IP
addresses/a single IP address from the known_hosts file.
SSH client maintains a list of IP addresses and associated RSA keys in the file
called known_hosts.
It is not possible to initiate a SSH session with a host whose IP address and key
does not match with the one stored in the known_hosts file. This mismatch can
happen if the an IP address is assigned to a different host or if the key of the host
is regenerated. In such cases, you have to clear the known_host file before you
can succesfully initiate the SSH client session. Also, the known_hosts file is not
VRF aware and is based only on the IP address. Hence, it is required to clear the
file before you can establish a session to the same IP address across VRFs.
