  - - org.apache.tools.ant.Task
    - - org.apache.tools.ant.taskdefs.optional.ssh.SSHBase
      - - org.apache.tools.ant.taskdefs.optional.ssh.SSHSession

- All Implemented Interfaces:
    java.lang.Cloneable, LogListener

      public class SSHSession
      extends SSHBase

  Establishes an ssh session with a remote machine, optionally establishing port forwarding, then executes any nested task(s) before closing the session.
  Since:
    Ant 1.8.0

    - #### SSHSession

          public SSHSession()

  - ### Method Detail

    - #### addTask

          public void addTask(Task nestedTask)

      Add a nested task to Sequential.
      Parameters:
        `nestedTask` - Nested task to execute sequentially

    - #### setTimeout

          public void setTimeout(long timeout)

      The connection can be dropped after a specified number of milliseconds. This is sometimes useful when a connection may be flaky. Default is 0, which means "wait forever".
      Parameters:
        `timeout` - The new timeout value in seconds

    - #### setLocaltunnels

          public void setLocaltunnels(java.lang.String tunnels)

      Changes the comma-delimited list of local tunnels to establish on the connection.
      Parameters:
        `tunnels` - a comma-delimited list of lport:rhost:rport tunnel specifications

    - #### setRemotetunnels

          public void setRemotetunnels(java.lang.String tunnels)

      Changes the comma-delimited list of remote tunnels to establish on the connection.
      Parameters:
        `tunnels` - a comma-delimited list of rport:lhost:lport tunnel specifications

    - #### execute

          public void execute()
                       throws BuildException

      Establish the ssh session and execute all nestedTasks
      Overrides:
        `execute` in class `Task`
      Throws:
        `BuildException` - if one of the nested tasks fails, or network error or bad parameter.

    - #### createLocalTunnel

          public SSHSession.LocalTunnel createLocalTunnel()

    - #### createRemoteTunnel

          public SSHSession.RemoteTunnel createRemoteTunnel()

    - #### createSequential

          public SSHSession.NestedSequential createSequential()

      This is the sequential nested element of the macrodef.
      Returns:
        a sequential element to be configured.
