Introducing NETCU

# Introduction

The Network Control Utility (NETCU) is the utility program system managers and operators use to configure and control networks that run TCPware.

This chapter summarizes the NETCU commands, by category, and describes how to run NETCU and send NETCU output to a file. Each command is described in detail in the next chapter, NETCU Commands.

## Running NETCU

Run NETCU directly from a terminal or from a command procedure. To run NETCU from your terminal, enter the following command at the DCL prompt:

NETCU

or

RUN TCPWARE:NETCU

The system displays the NETCU> prompt. NETCU is ready to accept your commands.

To have a startup command file execute each time you invoke NETCU, do the following:

1 Create a file containing the commands you want performed at the beginning of each NETCU session.

2 Define the NETCU_STARTUP logical to point to the file.

For example, you can include the following in your LOGIN.COM file:

ASSIGN SYS$LOGIN:NETCUSTART.COM NETCU_STARTUP

When you start NETCU, the NETCU_STARTUP logical points to the specified file (SYS$LOGIN:NETCUSTART.COM for example) and processes all the commands. Note that they system ignores all commands following an EXIT or QUIT command in the file. NETCU ignores any "commented-out" command lines in files (such as SERVICES.COM) that are used as input to NETCU. The commented-out line in the file should begin with the !, #, or ; character. NETCU does not execute the command line until you remove the character.

## Summary of NETCU Commands

This section lists each NETCU command and summarizes its purpose. Related commands appear together.

## ARP Commands

Use commands listed in Table 1-1 to maintain the Address Resolution Protocol (ARP) table. You rarely need to enter these commands since ARP maintains the table automatically.

Table 1-1 NETCU ARP Commands (Continued)

Command | Purpose
ADD ARP | Adds an entry to the ARP table
FIND ARP | Displays an entry from the ARP table
FLUSH ARP | Flushes the ARP table
REMOVE ARP | Deletes an entry from the ARP table
SET INTERFACE/ARP_* | Sets various ARP parameters for an interface
SHOW ARP | Displays the ARP table for the specified line

## Parameter Setting Command

Table 1-5 contains the TCPware parameters you can set using the NETCU SET command. You usually do not need to enter these commands because they are issued during configuration.

Table 1-5 NETCU SET Command

Command | Sets
SET parameter | Connection backlog values Default IP datagram time-to-live value IP datagram time-out time Default type of service used Whether subnets are local Maximum size of TCP segments sent Minimum TCP retransmission time Maximum TCP retransmission time TCP persistence timer’s initial value Default time zone offset or name

## Routing Commands

Table 1-6 lists the commands that configure and maintain routes. If you enter the necessary routing commands in the TCPWARE:ROUTING.COM file, TCPware executes them automatically at startup. If using GateD, do not also include routes in the ROUTING.COM file by using the ADD ROUTE command.

## MAIL-CONFIG Command Summary

Table 1-13 lists the commands you can run from the MAIL-CONFIG prompt.

The DCL command $ TCPWARE CONFIGURE/MAIL brings up the MAIL-CONFIG prompt.

Table 1-13 MAIL-CONFIG Command Summary (Continued)

MAIL-CONFIG Command | Description
ADD GATEWAY | Adds a mail gateway to another domain.
ADD LOCAL-DOMAIN | Adds a domain to a list of domains that the TCPware SMTP symbiont considers to be local. If users send mail to hosts beyond the local domains, TCPware forwards the mail to the mail hub specified by the FORWARDER parameter. The local domain list affects mail forwarding only when the FORWARD-REMOTE-MAIL parameter is TRUE.
ADD QUEUE-GROUP | Forms a mail queue grouping of nodes in a cluster, or adds new nodes to an existing queue group.
ATTACH | Attaches your terminal to another process.
CLEAR | Erases all information from the current configuration; same as ERASE.
DELETE GATEWAY | Deletes a mail gateway.
DELETE LOCAL-DOMAIN | Deletes a domain from TCPware's list of local domains.
DELETE QUEUE-GROUP | Deletes a queue group or removes a node from a queue group. When a node is removed from a named queue group, it becomes part of the default queue group.
ERASE | Erases all information from the current configuration; same as CLEAR.
EXIT | Saves the configuration file and exits from MAIL-CONFIG.
GET | Reads in a TCPware SMTP configuration file. (Functionally equivalent to USE.)
HELP | Invokes MAIL-CONFIG command help.
PUSH | Accesses the DCL command interpreter.
QUIT | Prompts you to save the configuration file if it has been modified, then exits MAIL-CONFIG.
REMOVE GATEWAY | Functionally equivalent to DELETE GATEWAY.
REMOVE QUEUE-GROUP | Functionally equivalent to DELETE QUEUE-GROUP.
SAVE | Saves the current configuration file.
SET ALIAS-FILE | Identifies the file that holds mail aliases.
SET DECNET-DOMAIN | Sets the domain name for DECnet mail.
SET DELIVERY-RECEIPTS | Specifies whether mail receipts are sent when incoming mail containing Delivery-Receipt-To: or Return-Receipt-To: headers is submitted to the SMTP queue.
SET DISABLE-PSIMAIL | When TRUE, the TCPware SMTP symbiont looks for messages addressed through PSImail, usually of the form PSI%address::user, and returns them to the sender marked user unknown.
SET DISALLOW-USER-REPLY-TO | When set to TRUE, prevents VMS MAIL users from setting a Reply-To: header address with the logical name TCPWARE_SMTP_REPLY_TO.
SET FORWARDER | Specifies the host that will forward mail messages to other hosts.
SET FORWARD-LOCAL-MAIL | Forwards mail addressed to users on the local host to a central mail hub specified by the FORWARDER parameter.
SET FORWARD-REMOTE-MAIL | Forwards mail addressed to users on non-local hosts to a central mail hub specified by the FORWARDER parameter.
SET HEADER-CONTROL | Specifies which RFC-822 message headers should be included in messages delivered to local VMS MAIL users.

SET POSTMASTER | Identifies the user responsible for mail on the system.
SET QUEUE-COUNT | Specifies the number of mail processing queues that should be created on a particular system.
SET REPLY-CONTROL | Specifies how Internet mail headers should be mapped to the VMS MAIL "From" header.
SET RESENT-HEADERS | When FALSE, the TCPware SMTP symbiont omits the Resent-From, Resent-To, and Resent-Date headers that are usually included when a message is forwarded using a VMS MAIL forwarding address.
SET RETRY-INTERVAL | Specifies the amount of time that elapses before another attempt is made to send a message after a failed attempt.
SET RETURN-INTERVAL | Specifies the amount of time that a message can remain in the processing queue before it is returned to sender.
SET SEND-BROADCAST-CLASS | Specifies the broadcast class to use to deliver immediate SEND messages.
SET SMTP-HOST-NAMES | Sets the host name from which all outgoing mail appears to be sent and aliases for which this host accepts incoming mail.
SET START-QUEUE-MANAGER | Determines whether START_SMTP.COM starts the VMS queue manager if it is not already running.
SHOW | Displays the current configuration.
SPAWN | Executes a single DCL command.
STATUS | Indicates whether the SMTP configuration has been modified.
USE | Reads in a non-standard configuration file.
VERSION | Displays the MAIL-CONFIG version and release information.
WRITE | Saves the current configuration file.

## Creating Output Files

You can send output to a file for the DEBUG command and any SHOW command except SHOW EXPORT, SHOW GROUP, SHOW MOUNT, SHOW PROXY, and SHOW STATISTICS. Enter the /OUTPUT=filespec qualifier after the command. For example, the following command sends all output for the SHOW CONNECTIONS command to the file MYFILE.TXT:

SHOW CONNECTIONS/OUTPUT=MYFILE.TXT

## Exiting NETCU

To exit NETCU, use the EXIT command or type Ctrl/Z. NETCU exits with the last error status, if any. DCL command procedures can use the $STATUS and $SEVERITY symbols to test for success or failure of the NETCU commands issued. A success status indicates that all commands succeeded. A warning, error, or severe status indicates that one or more commands failed to execute, either because of syntax errors or because of operational problems.

When possible, the status code is a System Service (defined in $SSDEF), RMS (defined in $RMSDEF), or shared (defined in $SHRDEF) status. In some cases, status codes are TCPware private codes with a facility number of 1577.

## Command Reference

Each NETCU command is described in detail in the next chapter, NETCU Commands. The command descriptions include the command:

• Purpose, and any suggestions or restrictions that may apply

• Format

• Parameters (if any)

• Qualifiers (if any)

• Examples (when possible)

## Troubleshooting NETCU

This section describes:

• Error messages that NETCU and NETCP can display at startup time

• NETCP error messages that OPCOM displays

• The NETCP.LOG file

## NETCU and NETCP Startup Messages

This section lists messages that NETCU and NETCP may issue when you start-up the network.

%TCPWARE_NETCU-E-LPCNF, error configuring line port
-SYSTEM-F-BADPARAM, bad parameter

Meaning: Software other than TCPware might be using a TCP/IP protocol or your system might be running LAT without DECnet.

Action: Be sure TCPware is the only software using the TCP/IP protocols. If LAT is running without DECnet, perform one of the following steps:

• Start TCPware before starting LAT.

%TCPWARE_NETCU-E-LPSTART, error starting line port
-SYSTEM-F-IVADDR, invalid media address

Meaning: Two local lines have the same internet address.

Action: Be sure the internet addresses for all lines are valid, and that no duplicates exist. No two lines can use the same network (or subnet) number. Check the host for a bad SLIP line definition or ask if the host has two Ethernet interface cards. If there are two Ethernet cards, they cannot have the same network number, for example, 192.15.10.1 and 192.15.20.1.

## NETCP OPCOM Messages

OPCOM messages inform you when a major event occurs on the network. Some messages are informational (such as when an Ethernet line is being restarted after a fatal error), while others alert you to a problem (such as when an error occurs in trying to restart a port).

NETCP sends a message to OPCOM when a network event occurs. OPCOM formats the messages and adds some information (such as a timestamp). It then displays the messages on the operator's console and writes them to the SYS$MANAGER: OPERATOR.LOG file. OPCOM messages should rarely occur.

All messages from NETCP OPCOM have the following prefix:

Status report from TCPware(R) for OpenVMS NETCP:

### Most Important OPCOM Messages

The following are the most important NETCP OPCOM messages.

Line line-id restarted after fatal error

Meaning: The network controller reported a fatal error. The line was restarting automatically.

Action: Investigate the controller error, especially if it occurs repeatedly.

Error restarting line line-id (prot-id protocol) after fatal error

Meaning: The network controller reported a fatal error and TCPware could not recover from the error. An accompanying message displays the error reported by the controller during the restartattempt. After some failures, TCPware may periodically try to restart the controller. The prot-id value is IP, ARP, RARP, LTP (long trailer packets), or STP (short trailer packets).

Action: Investigate the controller error.

### OPCOM Message for Interfaces

CAUTION! Maximum receive packet rate exceeded on line line-id (rate packets/second).

Meaning: The interface specified by line-id received more packets than were allowed. This may indicate that either the receive packet rate limit is too low or that a flood of packets were sent to the system and a network problem exists that should be corrected.

Action: If the limit is too low, raise it using SET INTERFACE /RECEIVE_LIMIT. If a network problem exists, investigate it and correct it.

### OPCOM Messages for IP-over-DECnet Lines

OPCOM may display the following messages for IP-over-DECnet lines.

DECnet link lost on line line-id

Meaning: The communication path between systems is lost. Some possible causes can be that a modem line is down, a cable has been unplugged, or the peer system is shut down.

Action: If the problem persists, investigate the cause for the lost line.

DECnet line line-id reconnected to peer

Meaning: The lost line was reconnected. Network operation is back to normal.

MTU for line line-id too small, ignoring packets larger than mtu bytes

Meaning: The peer end of the IP over DECnet line is sending datagrams that are larger than TCPware can handle.

Action: Increase the maximum transmission unit (MTU) for the IP-over-DECnet line at the receiving host, or lower it at the sending host. You can reset the MTUs for the receiving host by using the NETCU START/IP command or by reconfiguring the network.

Shutting down line line-id after receiving fatal error

Meaning: A fatal error was detected. This message is usually accompanied by another OpenVMS message which specifies the exact error.

Action: See your OpenVMS documentation.

## NETCP.LOG File

The TCPWARE:NETCP.LOG file logs each NETCP master server connection. You can use this file to obtain details on server errors, and to monitor access and security violations.

The NETCP.LOG file shows:

• When the connection was established

• Which protocol is servicing the connection

• The internet addresses of both hosts

• The name of the server process created

Before you examine the NETCP.LOG file, issue the NETCU SHOW SERVICES command. This command writes the current server information to the NETCP.LOG file.

Example 1-1 shows part of a sample NETCP.LOG file.
