set  [node node-id] xot sap sap-name ...

    Modifies the attributes of a XOT SAP entity, which represents the
    point at which the XOT entity gains access to the TCP/IP
    environment for the purposes of listening for inbound XOT
    connections.  The sap-name is a simple name that uniquely
    identifies a particular SAP instance.  The modifiable attributes
    and their data types (in brackets) are:

    local IP address [ip-address]
    local RFC1613 port number [integer]

    By default, XOT's single SAP entity is configured to listen
    on all available IP interfaces (as specified by the local IP
    address 0.0.0.0).  You can create multiple SAP entities, each
    listening on a unique IP address.  However, if you create
    more than one SAP entity, you must assign each entity a
    unique IP address; no SAP entity can use the 0.0.0.0 address.

    In other words, you may do this:

    set xot sap sap-0 -
      local ip address 0.0.0.0

    or this:

    set xot sap sap-0 -
      local ip address 123.23.49.235
    set xot sap sap-1 -
      local ip address 123.23.49.236

    but not this:

    set xot sap sap-0 -
      local ip address 0.0.0.0
    set xot sap sap-1 -
      local ip address 123.23.49.236

    LINK is a subentity of XOT SAP.

1  –  link

    set  [node node-id] xot sap sap-name link link-name...

    Modifies the attributes of a XOT SAP LINK entity, which
    represents a remote system with which XOT is allowed to
    communicate.  In the case of an inbound XOT connection,
    there must be a LINK entity with a matching remote IP address
    and a remote port number in order for XOT to accept the
    TCP/IP connection.  In the case of an outbound connection,
    the LINK entity specifies the remote IP address and remote
    port number of the system with which to attempt the TCP/IP
    connection.

    The sap-name and link-name are simple names which uniquely
    identify particular SAP and LINK instances.   The modifiable
    attributes of a XOT SAP LINK entity are (with data types in
    brackets):

    remote IP address [ip-address]
    remote RFC1613 port number [integer]

    Examples:

    set xot sap sap-0 link link-0 -
      remote ip address 125.65.82.34

    set xot sap sap-0 link link-0 -
      remote rfc1613 port number 1998

1.1  –  remote_ip_address

    Default:  0.0.0.0            Value:  IP address

    Specifies the remote IP address of the cooperating
    XOT system that implements RFC1613.  The IP
    address is specified as a numeric address in the
    form a.b.c.d.  Specify the address 127.0.0.1 for
    loopback testing.  For more information on TCP/IP
    loopback testing, see the TCP/IP Services for
    OpenVMS documentation.

1.2  –  remote_rfc1613_port_number

    Default:  1998               Value:  TCP port number

    Specifies the TCP port number to use for an outgoing
    connection.

    The remote system must be listening for inbound XOT
    connections on this port.  In other words, the
    remote system must have a SAP with this port as its
    Local RFC1613 Port Number.

2  –  local_ip_address

    Default:  0.0.0.0                Value:  IP address

    The IP interface (identified by the address) where the SAP
    entity will listen.  The default of 0.0.0.0 specifies that the
    SAP should listen on any available IP interface.

    You may choose to create one or more SAP entities to listen on
    specific IP interfaces.  However, if multiple SAP entities are
    in use, then none of them can use the local ip address of
    0.0.0.0.

3  –  local_rfc1613_port_number

    Default:  1998                   Value:  TCP port number

    The port number on which the SAP entity will listen for
    inbound XOT connections.  HP strongly recommends that you
    use the value 1998 as specified in RFC1613.
