This is normal for the first connection a new host. They are also informed that the authenticity of the host cannot be verified. When they connect, they are informed that the connection has been established. Our user is going to connect to an SFTP account called demo on the publicly accessible FTP server located at. ![]() If you want to connect to a remote or public FTP server use the sftp command. As we warned at the beginning of this article, the ftp command should only be used on internal networks. Readers familiar with the IP addressing system will have noticed that the 192.168 address of the FTP server used in the above examples is an internal IP address, also called a private IP address. Linux has the standard ftp command line program to deal with precisely that scenario. If your files aren't confidential or sensitive in any way, moving them around your internal network with FTP should be fine. If you're transferring files within your network, you should be safe - as long as no one on the network is packet-sniffing and eavesdropping on any sensitive documents as you transfer them. ![]() Anyone along the way can view your secrets. Login credentials like your username and password, as well as the data you download or upload, are transferred in clear text. Let's make this clear right from the outset: The File Transfer Protocol (FTP) dates back to the early 1970s and was written without any regard to security. FTP doesn't have the security of a modern protocol, but you may need to use it anyway. The File Transfer Protocol is older than most of our readers, but it's still going strong. ![]()
