Question
I try to remotely log in to the BMC system of the storage system to be powered on from a Linux host or another storage system via SSH. The system displays a message indicating that the login fails due to the invalid ESDSA host key. How do I update the public key?
Answer
Step 1 View the file path of saving the public key from the command output.
In this example, the public key is saved in the following path: /xxx/.ssh/known_hosts.
host:~ # ssh admin@xxx.xxx.xxx.xxx

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx [MD5].
Please contact your system administrator.
Add correct host key in /xxx/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /xxx/.ssh/known_hosts:3
ECDSA host key for xxx.xxx.xxx.xxx has changed and you have requested strict checking.
Host key verification failed.
Step 2 Edit the know_hosts file to delete the IP address and public key of the inaccessible storage system.
NOTE
When you remotely log in to the storage system using SSH next time, a new public key will be generated in the know_hosts file.
Step 3 Use SSH to remotely log in to the storage system again.
