I am a windows System Administrator. 2 days back I got a ticket that user is unable to establish SFTP session from a unix server to Windows Serv-u 15.1.0. I checked on server and found SSH private key(For SFTP) mentioned on Global settings but the path mentioned for Private key was actually deleted by someone from C: Drive. So I removed that private key path & password and user said he can access now. Now my security team is asking whether that private key is really required or not. also when user connected for the first time after removing private key from windows Serv-U Application he got below Warning.
The authenticity of host ******.com (xxx.xxx.xxx.xxx) can't be established.
RSA key fingerprint is XX.XXXX.....................................
