Server Configuration Parameters

SERVER-CONFIG Service Parameters

Table A-1 describes the service parameters you can set with the SERVER-CONFIG Utility.

Table A-1 SERVER-CONFIG Service Parameters (Continued)

Parameter

Description

ACCEPT-HOSTS

The list of hosts allowed access to this server. See Chapter 10.

ACCEPT-NETS

The list of networks or subnetworks that are allowed to access this server. See Chapter 10.

BACKLOG

The number of server connections to queue up before refusing to accept additional connections when MAX-SERVERS is reached.

CONFFILE

This file is used instead of the default MULTINET:NAMED.CONF file.

CONNECTED [ For servers supplied with MultiNet, do not change this parameter. When adding your own servers, you usually do not need to modify the default parameters.]

The name of the internal MULTINET_SERVER routine to call when a connection request is received. This varies by protocol and is normally not changed.

DEBUG

Sets the debug level of the Domain Nameserver (the default is no debugging). The larger the number, the more verbose the output. A value of 0 turns off debugging.

DEBUGFILE

This file is used instead of the default MULTINET:NAMED.RUN file.

DISABLED-NODES

The list of VMScluster nodes that cannot run this server. See Chapter 10.

ENABLED-NODES

The list of VMScluster nodes that can run this server. See Chapter 10.

FLAGSa

Various flags that control the operation of the service.

INITa

The name of the internal MULTINET_SERVER routine for initializing a service. This varies by protocol and is normally not changed.

LISTENa

The name of the internal MULTINET_SERVER routine for listening for connections to the service. This varies by protocol and is normally not changed.

LOG-ACCEPTS

Specifies whether to log successful connections to the service.

LOG-FILE

Destination of log messages. May be a VMS filename or OPCOM to direct messages to the VMS OPCOM process.

LOG-REJECTS

Specifies whether to log rejected connections to the service. A connection is rejected because of the combination of the REJECT-HOSTS, REJECT-NETS, and REJECT-BY-DEFAULT parameters.

MAX-SERVERS

The maximum number of service processes to allow at any one time. If this limit is reached, additional connections -- up to the number specified by the BACKLOG parameter -- are accepted but not processed until one of the previous connections completes.

MAXIMUM-TTL

Changes the maximum time-to-live (TTL) that resource records are cached from the default of 604800 seconds (1 week) to the specified value.

MINIMUM-TTL

Changes the minimum time-to-live (TTL) that resource records are cached from the default of zero (0) seconds to the specified value.
Note! It is recommended you use this command only if there is a specific need. This could cause problems in that you may be caching resource records for longer than the authoritative administrator intended.

PARAMETERS

Specifies service-dependent parameters passed to the initialization routine of built-in services. Normally not used for user-written services.

PRESERVE-CASE

Tells NAMED to keep the case of the response from the remote nameserver after doing a query.

PRIORITY

The VMS process priority to assign to created processes.

PROGRAM

The VMS filename of the image to run or merge.

QUERY-LOG

Toggles query logging ON and OFF. Query logging shows an informational message every time a query is received by the server. Query logging can be directed to OPCOM or a file in the MULTINET:NAMED.CONF file using the logging category queries.

REJECT-BY-DEFAULT

Whether to reject a connection from a host that does not match any of the ACCEPT-HOSTS, ACCEPT-NETS, REJECT-HOSTS, and REJECT-NETS lists.

REJECT-HOSTS

The list of hosts not allowed access to this server. See Chapter 10.

REJECT-MESSAGE

A text string to send down the network connection when a service is rejected.

REJECT-NETS

The list of networks or subnetworks not allowed access to this server. See Chapter 10.

REWRITE-TTL

Sets the time-to-live (TTL) that load balanced resource records are cached from the default of 300 seconds (5 minutes) to the specified value.

SERVICEa

The name of the internal MULTINET_SERVER routine to call to perform the service. This is normally Run_Program for user-written services.

SERVICE-NAME

The name of the service.

SOCKET-FAMILYa

The address family of the service; for example, AF_INET.

SOCKET-OPTIONSa

Socket options to be set via setsockopt(). See the MultiNet for OpenVMS Programmer's Reference for more information on socket options.

SOCKET-PORTa

The port number on which to to listen for connections.

SOCKET-TYPEa

The type of socket; for example, SOCK_STREAM (TCP) or SOCK_DGRAM (UDP).

WORKING-SET

The VMS working set to assign to created processes.
