You use the following utilities to configure and manage your router:
NOTE: You use monitoring utilities to check how each protocol is functioning and to help you identify potential problems. These include PPPCON, IPXCON, ATCON, and TCPCON.
The utilities you use to configure and manage Novell Internet Access Server 4.1 work in conjunction with the monitoring utilities to configure, monitor, and optimize the router and its connections.
NIASCFG enables you to configure Novell Internet Access Server 4.1. You can set up and customize your internetworking configuration for PPP, IPX, IP, AppleTalk, and the source route bridge by performing the following tasks:
NIASCFG records information in various configuration (*.CFG) files located in SYS:\ETC. Some of these files are present at system startup; others are created by NIASCFG, depending on the parameters you configure. The following is a partial list of these files:
WARNING: NIASCFG creates these files strictly for its own use; do not delete them or change their contents.
You use the Filter Configuration utility (FILTCFG) to set up and configure filters for the IPX, TCP/IP, and AppleTalk protocols and the source route bridge.
Filters provide a way to control the kind of information that is sent and received by a router by selectively discarding packets and routes of specified types. Filters are useful when you want to limit specific kinds of traffic to a certain part of your network topology, or when you want to provide a level of security. To configure filters, refer to Setting Up in the Filters documentation.
You use the Static Routing Configuration utility (STATICON) to open a connection to a remote IPX router and configure static routes and services at each end of the connection. To configure static routes with STATICON, refer to Configuring Static Routes and Services in the IPX documentation.
You can use STATICON to perform the following tasks:
You use the Call Manager utility (CALLMGR) to monitor the status of your WAN connections or to initiate and terminate WAN calls manually. When you start CALLMGR, you see a list of the current WAN connections. Each line displays the status of the call, the network interface, and the protocol used for the call. Outgoing calls display the name of the WAN call destination specified for the call. The name of the remote system might also be displayed.
Call error detailed information is available for calls that terminate while you are in CALLMGR.
You use the CPE Configuration utility (CPECFG) to configure and manage communications equipment from the server console. You can use CPECFG to establish communications with your communications equipment, such as a DSU/CSU or a modem, through the existing serial port on a server or standalone router.
You use the TECHWALK utility to record your Novell Internet Access Server 4.1 configuration. The TECHWALK utility records all information in NIASCFG or other console utilities by walking through the configuration parameters and saving them to the SYS:/ETC/TECHWALK.OUT file. All enabled items and summary lists are recorded.
You can access TECHWALK by typing one of the following command variations:
The console option runs TECHWALK to record only the information for the console utility you specified in the command.
Depending on the information you want to record, you should exit NIASCFG or the specific console before you run TECHWALK. Running TECHWALK might take from 5 to 60 minutes, depending on your configuration and the network traffic, and dedicates your machine to the process.
Novell Internet Access Server 4.1 also includes the commands described in this section to enhance the configuration and management utilities.
The INITIALIZE SYSTEM command lets you enable the Novell Internet Access Server 4.1 configuration by executing all commands in the system NETINFO.CFG file.
To use INITIALIZE SYSTEM, type the following command at the server prompt:
INITIALIZE SYSTEM
This command is typically executed from the INITSYS.NCF file during server startup.
NOTE: Executing INITIALIZE SYSTEM on a system that has already been initialized can generate errors as the system discovers that the commands in the NETINFO.CFG file have already been executed.
The REINITIALIZE SYSTEM command lets you enable configuration changes made since the commands in the NETINFO.CFG file were executed.
To use REINITIALIZE SYSTEM, type the following command at the server prompt:
REINITIALIZE SYSTEM
NOTE: The REINITIALIZE SYSTEM command is also available from the Internetworking Configuration menu.
REINITIALIZE SYSTEM compares the current NETINFO.CFG file with the previous one, which became effective with the execution of the INITIALIZE SYSTEM command. If REINITIALIZE SYSTEM finds any new or changed commands in the current NETINFO.CFG file, it executes them.
REINITIALIZE SYSTEM also informs any SNMP-registered NetWare Loadable ModuleTM (NLMTM ) file that it is executing. This callback mechanism enables NLM files that store configuration information outside the NETINFO.CFG file to recognize that changes to the configuration have taken place.
