Properties prop = new Properties();
prop.put("StrictHostKeyChecking", "no");
prop.put("PreferredAuthentications", "publickey,keyboard-interactive,password");
session.setConfig(prop);
session.connect();

String host = "host1.com";
int assignedPort = session.setPortForwardingL(0, host, 22);
LOGGER.info("Jump host the {} of agent {} and port forwarding {}", i, host, assignedPort);

sessions[i] = session = jsch.getSession(getUserName(), "127.0.0.1", assignedPort);
session.setPassword(getHostPassword());
userInfo = new UserInfo();
userInfo.setPassword(getHostPassword());
session.setUserInfo(userInfo); …
