Referencing a Properties File in the DHCP Vendor Options

This is the preferred method for setting JavaOS properties because dhcptab entries are limited to 255 characters.

Use the -i flag described in the preceding table in a dhcptab macro (see Chapter 2, JavaStation Boot Process: Theory of Operations ). The relevant line of the macro should have the following syntax:

JOScmd1="-ihttp://hostname[:port_number]/filename"

The text file should be located in the web server root directory. It should contain property settings using the flags described in the preceding table. It can also include arguments. Each property setting and argument should be typed on a separate line, with the separator hyphens mentioned above on their own line, as follows:

-Duser.timezone=PST
-djavaos.login=false

The following is a sample properties text file.
