Defining Boot Server Global Parameters

During the boot sequence, the boot server provide the JavaStation clients with information they need to operate properly. This information is divided into two categories: global parameters and local parameters. Global parameters are the parameters that are used by all JavaStation clients on the network (Table 2-1). Local parameters are defined for each JavaStation individually (Table 2-2).

Table 2-1 Network Computer Global Parameters

Parameters 

Description 

NIS Domain Name (optional) 

The NIS or NIS+ domain name in which the network computers reside.  

NIS Server Address(es) (optional) 

The list of host address(es) of NIS or NIS+ servers for the network computers. List of NIS or NIS+ server addresses configured in the network computer server database is displayed.  

DNS Domain Name 

The DNS domain name in which the network computers reside.  

DNS Server Address(es) 

The host address of the DNS server for the network computers. 

Boot Server Address 

The host address of the network computer boot server on the local network. 

Time Server Address 

The IP address of a server supporting the network time protocol (NTP). 

Router Address(es) (optional) 

A list of host address(es) of the routers to be used by the network computers. If not given, JavaOS broadcasts looking for a router.  

List of router addresses configured in the network computer server database is displayed.  

Lease Time (in days) 

The duration (in days) of the IP address lease to the network computer client. A value of -1 specifies an infinite lease. By default, this field is set to 3 days. After this period of time has expired with no DHCP server sending a DHCPACK packet, JavaOS shuts down the networking port.  

Lease Negotiation 

A "Yes" or "No" flag indicating whether lease negotiation is to be performed. If the lease time is set to the value "infinite" (-1), "Yes" has no meaning. 

Network Interfaces 

An access point to a system on a network. Each interface is associated with a physical device. However, a physical device can have multiple network interfaces. 

Input Method Server (optional) 

A server with a language engine to interpret the keyboard input method (for Korean, Chinese, and Japanese languages only). This server must be running a localized version of Solaris. 

Input Method Port (optional) 

The port number of the IIIMP server for the network computer. The IIIMP port number configured in the network computer server database is displayed. 

Time Zone 

Specify the timezone in which the JavaStation clients are locate d. This is a 3-letter field. For example, GMT. If an invalid timezone is specified, the timezone on the JavaStation clients default to GMT.  

By default the timezone specified in the network computer server database is displayed. 

Fonts Server (optional) 

The host address or host name of the fonts server for the network computers. Font server configured in the network computer server database is displayed. Server address is required if the fonts directory is specified.  

Fonts Directory (optional) 

The directory location of the fonts for the network computers. If a fonts server is specified, a fonts directory is required.  

Localized Resources Server (optional) 

The host address or host name of the localized resources server for the network computers. The server address is required if the localized resources directory is specified.  

Localized Resources Directory (optional) 

The directory location of the localized resources for the network computers. If a localized resources server is specified, this directory is required.  

Login Locales List (optional) 

The list of locales to be presented as choices to the user loging on to a network computer. By default the locales specified in the network computer server database are selected  

JavaOS Command Line (optional) 

A list of definitions of either JavaOS or system properties. A formatted text string that can be delivered by DHCP or other methods. There are no spaces between the option and the value. Different command line options are separated by a space. Exact syntax must be used to specify the command line options. By default, all JavaOS and system properties configured in the network computer server database (using JOScmd1) are displayed.

Table 2-2 Local Parameters

Option 

Description 

Host Name Prefix 

The host name of any network computer will be generated using the name_prefix. If the IP address of the network computer is aa.bb.cc.dd, then the generated host name for this computer will be name_prefix-dd.

Starting IP Address 

The initial host address you want to assign to the network computers being set up. If a host address is already used by some other system in the network, that address will be bypassed. 

Number of NCs 

The number of network computers you want to set up. Note that if an IP address is already used in the network, that address will not be used, resulting in one less client that will be set up. 

Enter Lease Time (days) 

The duration (in days) of the IP address lease to the network computer client. A value of -1 specifies an infinite lease. By default, this field is set to 3 days. After this period of time has expired with no DHCP server sending a DHCPACK packet, JavaOS shuts down the networking port.  

Default Application  

The application that will be run on this computer. Views specifies HotJava Views, and browser specifies HotJava Browser. You can add other applications as options to the Default Application list by using the Client Application Administration menu.

Select NC Locale 

The language the user will be using with this network computer. For Asian languages, the input method should also be selected. See Chapter 11, Setting Locales and Adding Fonts for a detailed description on this topic.

Select Keyboard 

Select the keyboard for use with this network computer. Currently, only PS2 keyboards are supported  

Dead Keys Support 

This property controls the behavior of the accent keys ' " ~ and ^ for ISO Latin locales. If this property is enabled, these keys are dead keys. When a dead key is pressed, no value is generated until the NEXT key is pressed. To get a single quote character, press this key twice. If this property is disabled, these keys will generate their expected value.  

Vendor Specific Options 

The DHCP specification enables hardware and software vendors to create their own DHCP options. These options are delivered through the use of the Client Class Identifier option and the Vendor Options option. This field enables you to specify the vendor specific options.  

Be careful when you use this feature; the Netra j administration interface software does not validate the value you enter in this field. If you do not want the login prompt for an application to be run on the network computer, type -djavaos.login=false.

See Chapter 9, Setting JavaOS Properties for additional information.

Before you can set up the JavaStation clients, you must define the global parameters for the boot server. (You will define the local parameters when you set up the JavaStation clients.) If your server is already on the network and is properly configured, Netra j obtains most of the global parameters automatically. To verify this information or to make any changes, refer to the appropriate modules for instructions.

For instructions on defining boot server global parameters, see "Configuring Global Parameters".
