let me start off by saying the Search feature on this forum [ahem] community is horendous
Anyway we replaced our C350 appliance with the newer C370 and now our M650 appliance complains that:
The host key for 111.122.133.144 (IP Address obfuscated) appears to have changed.
It is possible that someone is trying to hijack the encrypted connection to the remote host. Please use the logconfig->hostkeyconfig command to verify (and possibly update) the SSH host key for 111.122.133.144.
Now we have gone through this before but I forgot what to do, or what I have in my notes is not working, could you please help.
My notes say to login to the M Series and from the CLI delete the old host key, which we have done.
Then on the M Series go through the GUI and Establish Connection again for the new appliance, well when I do that I get the same error.

Hi,
this should work:
## Verifying the host keys
On your C370 appliance please access the command line and issue the logconfig command. Once done run the following sub-commands:
Choose the operation you want to perform:
- NEW - Create a new log.
- EDIT - Modify a log subscription.
- DELETE - Remove a log subscription.
- SETUP - General settings.
- LOGHEADERS - Configure headers to log.
- HOSTKEYCONFIG - Configure SSH host keys.
[]> hostkeyconfig
Currently installed host keys:
No host keys installed.
Choose the operation you want to perform:
- NEW - Add a new key.
- SCAN - Automatically download a host key.
- HOST - Display system host keys.
- FINGERPRINT - Display system host key fingerprints.
- USER - Display system user keys.
[]> host
This will display the system host keys for each appliance. Now you can access the CLI of the M-Series and run logconfig - HOSTKEYCONFIG - PRINT and verify the installed keys on the M650 with the the keys displayed on each C370.
## Deleting the installed host keys on M650
Run logconfig - HOSTKEYCONFIG - DELETE
## Scan for new host keys on M650
Run logconfig - HOSTKEYCONFIG - SCAN
After scanning for new keys please verify if they have been installed by using the PRINT option on the M650 and verify with the output of the HOST option on the C370.
Regards,
Enrico
