How to use SFTP (without server validation)

The topic How to use SFTP (introduction) describes the SFTP features of SSHFTPClient. This topic demonstrates the use of SFTP without server validation. Server validation should always be used in a production environment, but disabling it is a good way of getting started.

Using SFTP without server validation is simply a matter of getting a reference to the current validator and switching off host validation:

ftp.getValidator().setHostValidationEnabled(false);

For password authentication, the username and password of the SSH user must be passed into the setAuthentication method, and setRemoteHost must be set to the server's hostname or IP address. Note that some SFTP servers are set up to disallow password authentication, in which case the connection attempt will fail unless password authentication is enabled in the server configuration file.

After this a secure connection is established by calling connect():

ftp.setAuthentication(username, password);
ftp.setRemoteHost(host);
ftp.connect();
