Note: When a value other than *NONE is specified, all integrated server activity will be logged to either the monitor job log or the specified message queue. You should take the appropriate steps to secure this information on IBM i.

One method of restricting access to the integrated server information on IBM i is to create a message queue to contain the server activity. This message queue should be created with AUT(*EXCLUDE) and then any users that are to have access to the integrated server activity can be granted explicit authority to the message queue using the GRTOBJAUT command.

The value is specified in the form nnn.nnn.nnn.nnn , where nnn is a decimal number ranging from 0 through 255.

An internet address that has a binary value of all ones or all binary zeros for the network identifier (ID) portion or the host ID portion of the internet address is not valid.

Note: The internet address selected must be unique across all network server descriptions and the IBM i TCP/IP configuration.

TCP/IP route configuration (TCPRTE)

Specifies routes to remote destination systems or networks to the Transmission Control Protocol/Internet Protocol (TCP/IP) configuration for the integrated server.

A route specification has three elements: the route destination, the subnet mask, and the next hop internet address.

Two values uniquely define a route. They are the route destination field and the subnet mask. For *DFTROUTE values, the next hop element uniquely defines the route.

Notes:

  1. This parameter is only valid when Server connection specified *GUEST for the Network server type (TYPE) parameter.
  2. *NONE must be specified when TCPPORTCFG(*NONE) is specified.

Single values

*SAME
The value does not change.
*NONE
There is no routing specification needed for the integrated server.

Other values (up to 24 repetitions)

Element 1: Route destination

Specifies the remote network or host that is being added. The user must specify all four bytes that make up an internet address though some of the bytes may be equal to 0.

For example, a route to all the hosts on the 9.5.11 subnet is identified by entering 9.5.11.0 for the route destination. Used in combination with a subnet mask, the route destination will identify a route to a network or system.

*DFTROUTE
A TCP/IP default route is being added. A default route entry is used by the system to route data that is being sent to an undefined network or system. Multiple *DFTROUTE entries may be specified. The *DFTROUTE entries are used in the order specified. If a particular next hop gateway on a *DFTROUTE entry is not available, then the subsequent *DFTROUTE entry's next hop gateway specified will be used. This will continue until a *DFTROUTE entry's gateway is found that is active or the list of next hop gateway values is exhausted.
character-value
Specify the route destination being added. The route destination can be specified in the form, nnn.0.0.0 for Class A, nnn.nnn.0.0 for Class B, and nnn.nnn.nnn.0 for Class C, or nnn.nnn.nnn.nnn for any combination thereof, where nnn is a decimal number ranging from 0 through 255.

Note: Any combination thereof means that you may specify a route, such as 9.5.0.0 to the hosts on the 9.5 subnet even though all 9.5.x.x addresses are class A network addresses.

Exceptions:

  • The first byte (octet) must be greater than 0 and less than 255
  • The last byte (octet) may not equal 255.
  • The last byte (octet) may not equal 0 if *HOST is specified for the subnet mask value.
  • Routes to a broadcast address are not allowed.

Element 2: Subnet mask

A subnet mask value must be specified if *DFTROUTE or a route destination is entered for the route destination element. Subnet mask specifies a bit mask that identifies to TCP/IP which bits of the value specified for the route destination compose the network and subnet portions of the internet address. The subnet is identified by combining the route destination internet address and the subnet mask.

*NONE
There is no subnet mask. If *DFTROUTE is specified in the route destination element, then *NONE must be specified. *NONE is valid only for the *DFTROUTE route destination value.
*HOST
The internet address value specified in the route destination field is a host address. The subnet mask value is calculated to be 255.255.255.255.
character-value
Specify the mask of the subnet field.

The value is specified in the form nnn.nnn.nnn.nnn , where nnn is a decimal number ranging from 0 through 255.

For example, a destination route's internet address value of 129.35.11.0 is a Class B subnet. The network ID part of its address is 129.35. The upper 2 bytes must designate 255 in the subnet mask, for example, the subnet mask must appear like 255.255.x.x, where x is determined by the user. The portion of the subnet mask which is associated with the network portion of a particular class of address must equal 255.

Element 3: Next hop

The next hop value specifies the internet address of the next system (gateway) on the route. A route cannot be added unless the internet address specified by the next hop element is directly reachable through a network associated with one of the integrated server ports.

See the Fastpath for TCP/IP book for general information about internet addresses.

character-value
Specify the internet address of the next system on the route.

The value is specified in the form nnn.nnn.nnn.nnn , where nnn is a decimal number ranging from 0 through 255.

The host ID portion and the network ID portion of the internet address may not be all 0 bits or all 1 bits. An internet address that has all binary ones or all binary zeros for the network ID portion or the host ID portion of the internet address is not valid.

TCP/IP local host name (TCPHOSTNAM)

Specifies the short form of the host name associated with the integrated server.

Notes:

  1. *NWSD must be specified if *NONE is specified for the TCP/IP port configuration (TCPPORTCFG) parameter except when *AUX is specified on the Server operating system element of the Network server type (TYPE) parameter.
  2. This parameter is not valid when when Server operating system specified *ESX or *ESXE for the Network server type (TYPE) parameter.
*SAME
The value does not change.
*NWSD
Specifies that the host name for the integrated server is the same as the name of the network server description.
name
