I am testing a simple SSHFTPClient based client using public-key authentication. The client authentication seems okay but connection always failed due to the exception. Any ideas?
try {
// create client
log.info("Creating SFTP client");
SSHFTPClient ftp = new SSHFTPClient();
ftp.setRemotePort(21);
// set remote host
ftp.setRemoteHost("lcoalhost");
// turn off server validation
ftp.getValidator().setHostValidationEnabled(false);
log.info("Setting user-name and password");
ftp.setAuthentication("C:\\Test\\keys\\test.priv.ssh", "test", "testtest");
// connect to the server
ftp.connect();
log.info("Setting transfer mode to ASCII");
ftp.setType(FTPTransferType.ASCII);
// Shut down client
log.info("Quitting client");
ftp.quit();
log.info("Example complete");
} catch (Exception e) {
e.printStackTrace();
}
