NSCONTROL START
Enables the Network Services.
Syntax
NSCONTROL START[=service[,service]...]
Parameters
START[=services] Enables the Network Services (VT, Reverse VT, NFT,
RFA, RDBA, RPM, LOOPBACK, and NSSTAT). The first
START creates the Network Services control process,
called DSDAD. The optional service list (services)
allows you to select which of the services are
enabled for local or remote use.
Default (if the service list is omitted): enables
all services for both local and remote use.
The services which allow users on remote nodes to use
resources on the local node are as follows:
LOOPBACK Allows remote users to use the
loopback diagnostic server on the
local node.
NFT Allows remote users to transfer
files to or from the local node
using the DSCOPY command and
intrinsic.
NSSTAT Allows remote users to use the
NSSTATUS intrinsic to retrieve
network services information from
the local node.
RFA Allows remote users to access
files on the local node, using
the RFA and RDBA services.
RPM Allows remote users to create and
kill processes on the local node
using the Remote Process
Management service.
VT Allows remote users to logon to a
session on the local node.
VTR Allows remote users to access
local terminals using the Reverse
VT service.
VTA Allows remote users who are
running the Virtual Terminal
service over TCP implementations
which only support the ARPA
standard stream mode flow control
mechanisms to log onto the local
node.
The services which allow users on the local node to
use resources on remote nodes are:
NFTL Allows local users to transfer
files to or from remote nodes
using the DSCOPY command and
intrinsics.
NSSTATL Allows local users to use the
NSSTATUS intrinsic to retrieve
network services information from
the local and remote nodes.
RFAL Allows local users to open and
access files and databases on
remote nodes, using the RFA and
RDBA services.
RPML Allows local users to create and
kill processes on the local and
remote nodes using the RPM
service.
VTL Allows local users to log onto
remote nodes using the REMOTE
HELLO command.
VTRL Allows local users to access
terminals on remote nodes using
the Reverse VT service.
Discussion
If you issue an NSCONTROL START without specifying a service list, the
default is to start all services. You use the service list if you wish
to select which services to start, and whether local or remote users are
allowed to use the services. To allow remote users to use VT, VTR, VTA,
NFT, RFA/RDBA, NSSTAT, LOOPBACK, and RPM on your local node, you must
START the appropriate remote services. Additionally, if you wish to
allow local users to use VT, NFT, RFA/RDBA, RPM, and NSSTAT to remote
nodes, you must START the appropriate local services.
You must issue the NETCONTROL START command before the NSCONTROL START
command. This is because the Network Services depend on the network
transport subsystem. Refer to the NETCONTROL START command for more
information.
Example 1
Example 1 shows the command sequence necessary to start the Network
Services. Enter the NETCONTROL START command to initiate the network
transport before the NSCONTROL START command, as shown in the example.
Issuing the NSCONTROL START creates the DSDAD process and starts all the
user services.
To successfully initialize a node, the commands must be issued in the
order specified. At least one of the required NETCONTROL START commands
must be issued first, before the NSCONTROL START command.
:NETCONTROL START;NET=LAN1
:NSCONTROL START
Example 2
For security reasons, the node manager for this node has decided to
restrict the Network Services to outgoing only. The command shown in
example 2 enables users on the local node to use resources on remote
nodes. The reverse is not true. Users on remote nodes are not allowed
to logon or use any of the services on the local node. The status
display shows all the local services enabled and all the remote services
disabled.

Example 3
The network transport must be initialized before you can issue the
NSCONTROL START command. If not, the error messages shown in example 3
are displayed.
