Re: Remote Port Forwarding

[svyatoslav]

i did the same, but when trying to connect on forwarded port it falls.

server:
object SshDaemon {

  private val sshd = SshServer.setUpDefaultServer()

  def start(): Unit = {
    sshd.setPort(22)
    sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new
File("hostkey.ser")))
    sshd.setTcpipForwardingFilter(new ForwardingFilter {
      override def canForwardX11(session: Session): Boolean = true

      override def canForwardAgent(session: Session): Boolean = true

      override def canListen(address: SshdSocketAddress, session: Session):
Boolean = true

      override def canConnect(`type`: Type, address: SshdSocketAddress,
session: Session): Boolean = true
    })
    sshd.setPasswordAuthenticator(new PasswordAuthenticator {
      override def authenticate(username: String, password: String, session:
ServerSession): Boolean = username == "root" && password == "root"
    })
    sshd.start()
  }
  def stop() = sshd.stop(true)
}

client:
object SshAgent {

  private val ssh = SshClient.setUpDefaultClient()

  def start() = {
    ssh.setTcpipForwardingFilter(new ForwardingFilter {
      override def canForwardX11(session: Session): Boolean = true

      override def canForwardAgent(session: Session): Boolean = true

      override def canListen(address: SshdSocketAddress, session: Session):
Boolean = true

      override def canConnect(`type`: Type, address: SshdSocketAddress,
session: Session): Boolean = true
    })
    ssh.start()
    val connect = ssh.connect("root", "localhost", 22)
    connect.await()
    val session = connect.getSession
    session.addPasswordIdentity("root")
    session.auth().await()
    val local = new SshdSocketAddress("localhost", 14722)
    val remote = new SshdSocketAddress("localhost", 14730)
    session.startRemotePortForwarding(remote, local)
  }
  def stop() = ssh.stop()
}

netstat:
