Re: Openssh timeout

# man sshd_config

ClientAliveInterval
  Sets a timeout interval in seconds after which if no data has
  been received from the client, sshd will send a message through
  the encrypted channel to request a response from the client.  The
  default is 0, indicating that these messages will not be sent to
  the client.  This option applies to protocol version 2 only.

ClientAliveCountMax
  Sets the number of client alive messages (see above) which may be
  sent without sshd receiving any messages back from the client. If
  this threshold is reached while client alive messages are being
  sent, sshd will disconnect the client, terminating the session.
  It is important to note that the use of client alive messages is
  very different from KeepAlive (below). The client alive messages
  are sent through the encrypted channel and therefore will not be
  spoofable. The TCP keepalive option enabled by KeepAlive is
  spoofable. The client alive mechanism is valuable when the client
  or server depend on knowing when a connection has become inac-
  tive.

  The default value is 3. If ClientAliveInterval (above) is set to
  15, and ClientAliveCountMax is left at the default, unresponsive
  ssh clients will be disconnected after approximately 45 seconds.
