JavaStation Client Software Guide

TFTP

If a TFTP server will be involved in the boot sequence, set it up using the instructions below. For information on selecting TFTP to be used in the boot sequence, see Table 2-1.

Note -

Only experienced Solaris system administrators should set up boot services for JavaStation computers using Solaris commands. Inexperienced Solaris users should use the Netra j software. For information on Netra j, go to http://www.sun.com/netra-j or refer to the Netra j 3.0 Administrator's Guide.

To Set Up a JavaStation TFTP Server

  1. Follow the instructions in the TCP/IP and Data Communications Administration Guide to configure a server on the network as a TFTP server.

    This guide is available on the Web at http://docs.sun.com.

    Also, refer to the inetd(1M) and in.tftpd(1M) man pages.

  2. Use dhtadm to set the JavaStation boot protocol to TFTP.

    Set the JSBproto vendor-specific option to tftp. See "Vendor-Specific Options" for more information.

  3. Use dhtadm to add other TFTP boot information to the dhcptab file, as described in the following table:

    Table 2-6 DHCP Option Settings for TFTP

    If the TFTP server delivers.. 

    Set the following in dhcptab...

    The booter  

    • Set Bootfile to the path name of the booter file. The path name is assumed to be relative to the TFTP root directory. (If Bootfile is not set, the name of the booter file is assumed to be the Client Class Identifier - SUNW.JDM1 for a brick model; SUNW.JSIIep for a tower model.)

    • Set BootSrvA to the IP address of the TFTP server.

    • Set Rootpath to the directory on the NFS server where the JavaOS image is located.

    The JavaOS image 

    • Set Bootfile to the path name of the JavaOS image. The path name is assumed to be relative to the TFTP root directory.

    • Set BootSrvA to the IP address of the TFTP server.

    • To enable flash update after the boot, set Rootpath to the directory on the NFS server where the JavaOS image is located.

    (A case using all three of the above settings would be unusual. Typically, the JavaStation computer boots straight from flash, not the network, before a flash update.)
