WinSCP FTP client connection to AIX gives "host key not found" warning.
 

Hi folks,

While using the WinSCP FTP client to connect to an AIX box (for the first time), I get the following message:

The server's host key was not found in the cache. You have no guarantee that the server is the computer you think it is.

The server's rsa2 key fingerprint is:
ssh-rsa **:**:**:....:**

If you trust this host,....


My query here being - how do I verify that the server I'm connecting to is the one intended from the ssh-rsa key provided?

that is a nuance of ssh. Every time you connect to a server for the first time it will accept whatever key the remote system provides and then store it in a file called known_hosts. every ssh client does this and since sftp is part of the ssh suite it is no different. If you don't wish to see that message there is a way to generate the key yourself on the unix system and then copy and paste it to your windows system. Or you can take the easy road and just accept it. The 2nd time you connect you shouldn't see that message anymore.

Ask the administrator of the server.
