L
local host The host system you are currently
working from.
local node Same as host system.
loopback The routing of messages from a node back
to itself.
N
name space The set of possible names allowed in a
given environment. The POSIX name space, which
follows hierarchical file system syntax (i.e.,
\sys\pub\myfile) is distinct from the MPE/iX
name space, which follows MPE naming rules (i.e.,
MYFILE.PUB.SYS).
network address Either the network portion of an
IP address (as opposed to the node portion) or a
node’s X.25 address when referring to X.25
networks.
network directory A file containing information
required for one node to communicate with other
nodes in 1) an internetwork, 2) an X.25 network, or
3) a network that contains non-HP nodes. The active
network directory on a node must be named
NSDIR.NET.SYS.
NI See Network Interface.
Network Interface The collection of software that
enables data communication between a system and
a network. A node possesses one or more network
interfaces for each of the networks to which it
belongs. Examples of network interfaces include
Local Area Networks (LANs), point-to-point (router),
X.25, token ring, SNA, loopback, and gateway half.
The maximum number of supportable network
interfaces is 12, one of which is reserved for
loopback.
Network Services Software application products
that can be used to access data, initiate processes,
and exchange information among nodes in the
network. The NS 3000/iX Network Services include
RPM, VT, RFA, RDBA, and NFT.
NMCONFIG.PUB.SYS The file that contains all
the network configuration data for the HP e3000
computer on which it resides. It includes information
about the clients that can access the system as well
as information about any Network Services (NS)
products running on the system. This is the only file
name allowed.
NMMAINT Node Management services
MAINTenance utility. A utility that lists the
software module version numbers for all HP
AdvanceNet products, including NS 3000/iX. It
detects missing or invalid software modules.
NMMGR Node Management Services Configuration
Manager. A software subsystem that enables you to
configure network connectivity and access
parameters for an HP e3000 computer.
NMMGRVER Node management services
conversion utility. A conversion program that
converts configuration files created with NMMGR
from an earlier version to the latest format.
node A computer that is part of a network. The
DTC, or Datacommunications and Terminal
Controller that enables asynchronous devices to
access the HP e3000, is also considered to be a node
and has its own address.
node address The node portion of an Internet
Protocol (IP) address.
Node Management Services Configuration
Manager See NMMGR.
node name A character string that uniquely
identifies each system in a network or internetwork.
Each node name in a network or internetwork must
be unique; however, a single node can be identified
by more than one node name.
NS See Network Services.
NS 3000/iX Link Software and hardware that
provides the connection between nodes on a
network. Some of the NS 3000/iX links available are
the ThinLAN 3000/iX Link and its ThickLAN option,
the DTC/X.25 iX Network Link, and the NS
Point-to-Point 3000/iX Link.
NS 3000/iX Network Services Software
applications that can be used to access data, initiate
processes, and exchange information among nodes in
a network. The services are RPM, VT, RFA, RDBA,
and NFT.
