''Network Control Program''
 +
 
 +
''The Network Control Program (NCP) performs three primary functions: displaying statistics, controlling network components, and testing network components.''
 +
 
 +
''Using the DECnet-VAX NCP utility, an operator can display the status of DECnet activity at the local node.''
 +
''The user can choose to display statistics related to the local node, other DECnet-VAX nodes, and communication lines, including information on traffic and errors.''
 +
''Using the DECnet-VAX NCP utility, the local operator can also perform many network control functions such as reconfiguring the local node’s network parameters, starting and stopping lines, activating the local node, and down-line loading DECnet-11S systems.''
 +
 
 +
''NCP allows the user to perform a series of tests that aid in isolating problems. NCP can be used to send and receive test messages over individual lines either between nodes or through other controlled loopback arrangements. The messages can then be compared.''
 +
 
 +
==NCP Remarks==
 +
* '''NCP''' is started with:
 +
** '''MC NCP''' (the oldfashioned RSX-11-way), or:
 +
** '''RUN SYS$SYSTEM:NCP''' (the VMS-way)
 +
* You can either:
 +
** enter complete NCP commands, or:
 +
** start with only the beginning of an NCP command and after pressing '''[Enter]''' NCP will show you how you can continue
 
* '''LOCAL''' is what '''EXECUTOR''' is in newer NCP versions
 
* '''LOCAL''' is what '''EXECUTOR''' is in newer NCP versions
 
* '''KNOWN''' means "all" (kind of a wildcard)
 
* '''KNOWN''' means "all" (kind of a wildcard)

===NODE===
 +
----
 +
A '''NODE''' is a computer participating in a [[DECnet]] network.
 +
 +
NODEs have got DECnet numbers (= DECnet adresses) in the range 1 to 31 ([[DECnet#Phase II (1976)|DECnet Phase II]]).
 +
 +
NODEs have got names up to 6 characters long.
  
 
===LOCAL===
 
===LOCAL===
 +
----
 +
'''LOCAL''' is the DECnet NODE where '''NCP''' is executed.
 +
 +
===REMOTE===
 +
----
 +
'''REMOTE''' are other DECnet NODEs connected via DECnet.
  
 
===LINE===
 
===LINE===
 +
----
 +
A '''LINE''' is the physical connection between two DECnet NODEs.
  
−
===OBJECT===
+
A NODE can have more than one LINE (restrictions apply).
  
−
===NODE===
+
A LINE is named after the interface on the local end; i.e. '''DMC11_0''' is the line of the first [[DMC11]] on the local node, '''DMC11_1''' is the second, and so on.
  
 
===LINK===
 
===LINK===
 +
----
 +
A '''LINK''' is an active data connection over a LINE.
 +
 +
A LINK has got a unique number.
 +
 +
A LINE can carry serveral LINKs at a time in parallel (restrictions apply).
  
 
===COUNT===
 
===COUNT===
 +
----
 +
'''COUNT''' is a collection of statistical numbers, e.g. for LOCAL, a LINE, or a LINK.
 +
 +
===OBJECT===
 +
----
 +
An '''OBJECT''' is a program that works on behalf of a DECnet function.
 +
 +
OBJECTs have got names up to 8 characters long and a unique number.

==DECnet/VAX V1.3 Peculiarities==
 +
 +
Some DECnet/VAX V1.3 Peculiarities I found out while configuring resp. using it.
 +
 +
=== No DECnet CIRCUITS ===
 +
 +
At the time of DECnet/VAX V1.3 (DECnet Phase II) there were no DECnet '''CIRCUIT'''s.
 +
 +
The term '''CIRCUIT''' only came into being when DECnet PHASE III was introduced where certain types of '''LINE''' could have multiple '''CIRCUITS''' (logical connections that carry information between two nodes).
 +
 +
=== Definition of the LOCAL (EXECUTOR) Node in Two Places ===
 +
 +
The '''LOCAL''' node in DECnet/VAX V1.3 (called '''EXECUTOR''' in later versions) needs two definitions:
 +
* The <code>'''DEFINE LOCAL'''</code> definition, and
 +
* additionally a <code>'''DEFINE REMOTE'''</code> definition.
 +
 +
See the sample DECnet V1.3 [[NCP DECnet/VAX V1.3#Example NCP Command File (CONFIGNET.COM)|configuration file]] for details.
 +
 +
=== Required Receive Password ===
 +
 +
While in newer DECnet versions a receive password for nodes is optional, it is mandatory in DECnet/VAX V1.3:
 +
 +
NCP>'''DEFINE REMOTE'''
 +
REMOTE NODE NAME(1-6 CHARS):'''TEST'''
 +
REMOTE NODE NUMBER(2-240):'''99'''
 +
FILENAME FOR SECONDARY LOADER(1-13 CHARS,OPTIONAL):
 +
FILE USED FOR TERTIARY LOADER(1-13 CHARS,OPTIONAL):
 +
DOWN-LINE LOAD FILE(1-13 CHARS,OPTIONAL):
 +
BOOTSTRAP PASSWORD(EXACTLY 4 CHARS,OPTIONAL):
 +
PASSWORD REMOTE SENDS DURING INIT SEQUENCE(1-8 CHARS):'''MUSTBE'''
 +
PASSWORD REMOTE EXPECTS DURING INIT SEQUENCE(1-8 CHARS,OPTIONAL):
 +
NON-PRIVILEGED DEFAULT USER IDENTIFICATION( 1-16 CHARS,OPTIONAL):
 +
NON-PRIVILEGED DEFAULT PASSWORD( 1-8 CHARS,OPTIONAL):
 +
NON-PRIVILEGED DEFAULT ACCOUNT NAME ( 1-16 CHARS,OPTIONAL):
 +
PRIVILEGED DEFAULT USER ID( 1-16 CHARS,OPTIONAL):
 +
PRIVILEGED DEFAULT PASSWORD( 1-8 CHARS,OPTIONAL):
 +
PRIVILEGED DEFAULT ACCOUNT NAME( 1-16 CHARS,OPTIONAL):
 +
TIMEOUT CONSTANT FOR NSP CONNECT SEQUENCES IN SECONDS(1-120,OPTIONAL):
 +
NAME OF REMOTES SERVER NODE(1-6 CHARS,OPTIONAL):
 +
SERVERS LINE TO REMOTE(DEV_#_#_#,OPTIONAL):
 +
REMOTES HOST NODE(1-6 CHARS,OPTIONAL):
 +
%NCP-S-RECADD, new database record added
 +
NCP>
 +
 +
=== Privileged Default User ID and Password ===
 +
 +
The:
 +
* <code>'''PRIVILEGED DEFAULT USER ID'''</code> (paramter name: <code>'''PRVID'''</code>) and the
 +
* <code>'''PRIVILEGED DEFAULT PASSWORD'''</code> (paramter name: <code>'''PRVPSW'''</code>)
 +
must be set to the VMS SYSTEM Account and Password (or maybe another sufficient privileged account values (not yet tested)) of the local node; otherwise the local node will not be able to connect to other nodes.
 +
 +
=== Line Status Change ===
 +
 +
If a DECnet line goes off:
 +
 +
Opcom, DECnet line XMA0: had a DSR on-to-off transition
 +
 +
and comes up again, DECnet V1.3/VAX does not recognize this automatically and you have to intervene manually:
 +
 +
NCP>'''SET STATE LOCAL OFF'''
 +
    Opcom, 08:57:35.33, NETACP      Accnt=       
 +
    Opcom, DECnet line XMA0: shutting down
 +
 +
NCP>
 +
    Opcom, 08:57:35.36, NETACP      Accnt=       
 +
    Opcom, DECnet shutting down
 +
 +
NCP>'''SET STATE LOCAL ON'''
 +
    Opcom, 08:57:48.42, NETACP      Accnt=       
 +
    Opcom, DECnet starting
 +
 +
NCP>'''SET STATE LINE DMC11_0 ON'''
 +
    Opcom, 08:58:12.55, NETACP      Accnt=       
 +
    Opcom, DECnet line XMA0: starting
 +
 +
NCP>
 +
    Opcom, 08:58:26.86, NETACP      Accnt=       
 +
    Opcom, DECnet line XMA0: received a valid node init from address: 3, name: VAX2
 +
 +
NCP>
 +
 +
Maybe there's a more elegant way, but I don't know it yet.

A VERY ROUGH DRAFT!

What is NCP?

Citation from "DECnet-VAX, Version 1.3 Software Product Description":

Network Control Program

The Network Control Program (NCP) performs three primary functions: displaying statistics, controlling network components, and testing network components.

Using the DECnet-VAX NCP utility, an operator can display the status of DECnet activity at the local node. The user can choose to display statistics related to the local node, other DECnet-VAX nodes, and communication lines, including information on traffic and errors. Using the DECnet-VAX NCP utility, the local operator can also perform many network control functions such as reconfiguring the local node’s network parameters, starting and stopping lines, activating the local node, and down-line loading DECnet-11S systems.

NCP allows the user to perform a series of tests that aid in isolating problems. NCP can be used to send and receive test messages over individual lines either between nodes or through other controlled loopback arrangements. The messages can then be compared.

NCP Remarks

  • NCP is started with:
    • MC NCP (the oldfashioned RSX-11-way), or:
    • RUN SYS$SYSTEM:NCP (the VMS-way)
  • You can either:
    • enter complete NCP commands, or:
    • start with only the beginning of an NCP command and after pressing [Enter] NCP will show you how you can continue
  • LOCAL is what EXECUTOR is in newer NCP versions
  • KNOWN means "all" (kind of a wildcard)
  • Use [ESC] to abort NCP commands

NCP "Elements"

NODE

A NODE is a computer participating in a DECnet network.

NODEs have got DECnet numbers (= DECnet adresses) in the range 1 to 31 (DECnet Phase II).

NODEs have got names up to 6 characters long.

LOCAL

LOCAL is the DECnet NODE where NCP is executed.

REMOTE

REMOTE are other DECnet NODEs connected via DECnet.

LINE

A LINE is the physical connection between two DECnet NODEs.

A NODE can have more than one LINE (restrictions apply).

A LINE is named after the interface on the local end; i.e. DMC11_0 is the line of the first DMC11 on the local node, DMC11_1 is the second, and so on.

LINK

A LINK is an active data connection over a LINE.

A LINK has got a unique number.

A LINE can carry serveral LINKs at a time in parallel (restrictions apply).

COUNT

COUNT is a collection of statistical numbers, e.g. for LOCAL, a LINE, or a LINK.

OBJECT

An OBJECT is a program that works on behalf of a DECnet function.

OBJECTs have got names up to 8 characters long and a unique number.

DECnet/VAX V1.3 Peculiarities

Some DECnet/VAX V1.3 Peculiarities I found out while configuring resp. using it.

No DECnet CIRCUITS

At the time of DECnet/VAX V1.3 (DECnet Phase II) there were no DECnet CIRCUITs.

The term CIRCUIT only came into being when DECnet PHASE III was introduced where certain types of LINE could have multiple CIRCUITS (logical connections that carry information between two nodes).

Definition of the LOCAL (EXECUTOR) Node in Two Places

The LOCAL node in DECnet/VAX V1.3 (called EXECUTOR in later versions) needs two definitions:

  • The DEFINE LOCAL definition, and
  • additionally a DEFINE REMOTE definition.

See the sample DECnet V1.3 configuration file for details.

Required Receive Password

While in newer DECnet versions a receive password for nodes is optional, it is mandatory in DECnet/VAX V1.3: 

NCP>DEFINE REMOTE
REMOTE NODE NAME(1-6 CHARS):TEST
REMOTE NODE NUMBER(2-240):99
FILENAME FOR SECONDARY LOADER(1-13 CHARS,OPTIONAL):
FILE USED FOR TERTIARY LOADER(1-13 CHARS,OPTIONAL):

SERVERS LINE TO REMOTE(DEV_#_#_#,OPTIONAL):
REMOTES HOST NODE(1-6 CHARS,OPTIONAL):
%NCP-S-RECADD, new database record added
NCP>

Privileged Default User ID and Password

The:

  • PRIVILEGED DEFAULT USER ID (paramter name: PRVID) and the
  • PRIVILEGED DEFAULT PASSWORD (paramter name: PRVPSW)

must be set to the VMS SYSTEM Account and Password (or maybe another sufficient privileged account values (not yet tested)) of the local node; otherwise the local node will not be able to connect to other nodes.

Line Status Change

If a DECnet line goes off: 

Opcom, DECnet line XMA0: had a DSR on-to-off transition

and comes up again, DECnet V1.3/VAX does not recognize this automatically and you have to intervene manually: 

NCP>SET STATE LOCAL OFF
   Opcom, 08:57:35.33, NETACP       Accnt=        
   Opcom, DECnet line XMA0: shutting down

NCP>
   Opcom, 08:57:35.36, NETACP       Accnt=        
   Opcom, DECnet shutting down

NCP>SET STATE LOCAL ON
   Opcom, 08:57:48.42, NETACP       Accnt=        
   Opcom, DECnet starting

NCP>SET STATE LINE DMC11_0 ON
   Opcom, 08:58:12.55, NETACP       Accnt=        
   Opcom, DECnet line XMA0: starting

NCP>
   Opcom, 08:58:26.86, NETACP       Accnt=        
   Opcom, DECnet line XMA0: received a valid node init from address: 3, name: VAX2

NCP>

Maybe there's a more elegant way, but I don't know it yet.

Miscellaneous Messages

ABORT, abort
Facility: VAX/VMS System Services
Explanation: An attempted operation was aborted:
1. The system returns this status for an I/O request that was canceled before it was completed.
2. Following a network request, this status indicates that a logical link was disconnected.
User Action: The operating system does not normally display this message; user programs should be coded to detect and respond to the status return.

ACCQUOTA, ACCOUNT had inadequate quota at remote node
Facility: VAX/VMS System Services
Explanation: This severe error message is associated with a Status code returned from a system service request. An attempt was made to initiate a DECnet logical link connection. The target object is already using its quota of logical links or some other resource.
User Action: This condition is not usually permanent. Try to initiate the connection later. Consult the DECnet-VAX User's Guide for additional information.

BADPARAM, bad parameter value
Facility: VAX/VMS System Services
Explanation: A value specified for a system function is not valid. Several conditions can cause this error:
1. If this message occurs as a result of a call to a file system ACP function, it indicates that parameter listoptions are not valid.
2. If this message occurs as a result of a call to the Formatted ASCII Output (SFAO) system service, it indicates that a control string contained an unknown directive.
3. If this message occurs as a result of a call to a network ACP control function, it indicates that one of the function parameters is out of range or has a bad format.
4. If this message is associated with a status code returned by a request to a DR32 interface, an attempt was made to set the data rate higher than the rate allowed by the SYSGEN parameter /XFMAXRATE.
5. If this message is associated with a status code returned by a request to a DR11-W interface, an odd transfer count was specified.
User Action: Determine the system service call that returned the error, using the debugger if necessary. Verify that the call to the service was coded correctly. See the VAX/VMS System Services Reference Manual for coding specifications.

BUG_DAP, internal network error condition detected; DAP code=xxxxxx
Facility: VAX-11 RMS
Explanation: A Data Access Protocol violation was detected by VAX-11 RMS while attempting to communicate with the Remote Access Listener.
User Action: Collect as much information as possible and submit an SPR. The status value (STV) field of the FAB or RAB contains the DAP status code. Consult the DECnet-VAX User's Guide to interpret the status code. Note, however, that the explanation is intended for users who are familiar with DAP.

CRC, network DAP level CRC check failed
Facility: VAX-11 RMS
Explanation: CRC checksums computed by VAX-11 RMS and the File Access Listener (FAL) program did not match when compared during an RMS close operation.
User Action: The file that was created or modified may be corrupted. Repeat the file access. If the CRC error on close persists, the communication hardware is malfunctioning.

DIRFULL, directory is full
Facility: VAX/VMS System Services
Explanation: This message is associated with a status code returned from a file system ACP QIO request. The message indicates that an error occurred while a disk file was being created because the directory specified is full and cannot catalog any more entries. The maximum size of a directory file is 1024 blocks.
If associated with a DECnet operation, this message indicates that the directory of declared network names is full.
User Action: Delete or purge unwanted files from the directory and repeat the request; specify a different directory for the output file; or, organize the directory into subdirectory levels to obtain more cataloging space.

FILALRACC, file already accessed on channel
Facility: VAX/VMS System Services
Explanation: This message is associated with a DECnet operation. A logical link already exists or is pending.
User Action: Check for a programming error.
