Table 9-1 JavaOS General Properties
Property Name |
Default Value |
Description |
---|---|---|
javaos. mountlist |
null |
A semicolon-separated list of pairs of network paths and local paths. As soon as the network is up, each remote file system is mounted onto the local file system. The syntax of each pair is: server:remote_path|local_path For example, to enable localized keyboards, mount /REMOTE from the server and file system that has JavaOS: -djavaos.mountlist=myserver:/export/root/javaos/classes|/REMOTE See Chapter 11, Setting Locales and Adding Fonts" for more details. |
javaos. snmpSysContact |
null |
This property sets the value that will be returned in the system Management Information Base (MIB) for the system contact field. It can be set with a string of your choice, which should be enclosed in quotes. Example: -djavaos.snmpSysContact="Bob" |
javaos. snmpSysLocation |
null |
This property sets the value that will be returned in the system MIB for the system Location field. It can be set with a string of your choice, which should be enclosed in quotes. Example: -djavaos.snmpSysLocation="Sun MPK14" |
javaos.kbd |
null |
By default, JavaOS assumes you are using a U.S. keyboard, To enable a different keyboard, use the syntax javaos.kbd=keyboard. Possible values for keyboard are provided in Chapter 11, Setting Locales and Adding Fonts." |
javaos. consoleHotKey |
VK_PRINTSCREEN |
This property sets the keyboard hotkey that activates the JavaStation console, which displays debugging information. The value of the property is the JDK virtual keycode name for the hotkey. The following codes are valid:
The value of this property is case-insensitive; VK_PRINTSCREEN and vk_PrInTSCreen are equivalent. |
javaos.login |
true |
If true, JavaOS displays a login screen after booting and before starting the initial application. If false, JavaOS runs the main application as soon as it boots, without displaying a login screen. This means there is no user home directory and no system properties are read from a properties file. You may want to use the javaos.homedir property to specify an NFS directory to mount (see below). |
javaos. alwaysUpdate |
null |
This property specifies that JavaOS is always or never updated in the JavaStation's flash memory, regardless of the value of the JavaOS checksum. It is useful for public kiosks or other systems where user input is not expected.
Note that if the DHCP checksum is not present or is zero, the flash is not updated. |
javaos. allowGuest |
false |
If true, the login screen (if displayed at all) will contain a guest login button. |
javaos.homedir |
null |
This property specifies the NFS path JavaOS should mount if NIS is not used to find the path based on the user name. The NFS path is specified as hostname:/path. This property is most often used if the javaos.login property is set to false, or, if NIS is not enabled or available, to determine the directory to use for the properties file that is read by HotJava at launch. |
javaos.dns |
true |
When set to true, host name-to-address and address-to-host name resolution is performed using the DNS protocol. See also javaos.nis. If lookup using NIS is enabled also, NIS is attempted first, and DNS is attempted only if NIS lookup fails. See also javaos.hostaddrmap and javaos.hostnamemap. |
javaos. hostnamemap |
host. byname |
The name of the NIS map used to perform host name-to-address resolution. |
javaos. hostaddrmap |
host. byaddr |
The name of the NIS map used to perform address-to-host name resolution. |
javaos. homedirmap |
auto.home(sought first), auto_home |
If NIS is enabled, this property is used to set the name of the NIS map used by JavaOS to determine a user's home directory. |
javaos.nis |
true |
When set to true, login authentication, host name-to-address resolution and address-to-host name resolution are performed using the NIS protocol. See also javaos.dns. If lookup using DNS is also enabled, NIS is attempted first, and DNS is attempted only if NIS fails. |
