Я получаю ошибку при попытке установить соединение с удаленным сервером, используя Jcraft. < /p>

Часть кода, где происходит исключение: < /p>
try {
JSch ssh = new JSch();
String privatekey = PropertiesUtil.getProperty(PropertiesUtil.Constant.SSH_PRIVATEKEY.getValue());
this.LOG.info("Private key found: " + privatekey);
ssh.addIdentity(privatekey);
String username = PropertiesUtil.getProperty(PropertiesUtil.Constant.FTP_USERNAME.getValue());
String host = PropertiesUtil.getProperty(PropertiesUtil.Constant.FTP_SERVER.getValue());
this.LOG.info("Username: " + username);
this.LOG.info("Host: " + host);
session = ssh.getSession(username, host, 22);
this.LOG.info("Got jcraft session");
session.setConfig("StrictHostKeyChecking", "no");
this.LOG.info("Set strictHostKeyChecking to -> no");
session.connect();
Я могу такого SFTP, даже без явного предоставления ключа или пароля: < /p>
sftp user@host
< /code>
Таким образом, ключ открытого ключа распределяется на удаленный сервер. < /p>
Еще несколько журналов здесь для справки: < /p>
