Please Help... Host key has changed

ezhiker · Post by **ezhiker** » Tue May 03, 2011 2:21 pm

Hi there. I hope someone can help me with this. I made some changes to the server config and somehow it has changed the server key fingerprint so all the SFTP clients are asking to update their key cache.

These clients are automated so I would like to fix this on the server side. Is there any way to revert to the original host key? I reverted my config changes but that didn't fix it. Does anyone know where the server SSH key is stored? Why would it change?

Thanks!

certs are located in:

C:\Program Files\CoreFTPServer\certs

directory.

Depending on your version of Windows, and whether you are running as an administrator, the CoreFTPServer\certs directory can be potentially in more than one place (due to UAC Virtualization).

This might be responsible for the apparent "loss" of your configuration and/or certificate files, or instances where your configurations are different due to more than one config.dat (contains most Core FTP Server settings).

Build 439 and greater have the ability to change the certificate directory, which should help alleviate this issue.
