FTPS SSH Host Key after IP Address Change
- by David George
I have a Secure FTP (FTPS) server that my remote sites to upload files to daily via scripted routines that run. I have had issues in the past when upgrading hardware and deploying new servers causing the RSA Fingerprint to change for that server. Then all my remote sites can't connect until I have the old key removed (usually via ssh_keygen -r myserver.com).
I now have to change the IP address for myserver.com and I wondered if there is anyway to proactively generate new host keys so that when the server address changes all my FTPS client remote sites don't break?
