Setting up for Boot with TFTP

Now we need to set up the last step on our server: the TFTP configuration. For this step, you will need the

kernel you created (using the "NFS−Root" option) or the piggybacked kernel/fs boot image (using the

"Embedded−Root" option), the appropriate PROLL, and some knowledge of hexadecimal numbering.

The first thing you need to do is verify that "TFTPd" is enabled in your "/etc/inetd.conf" file:

tftp dgram udp wait root /usr/sbin/tcpd in.tftpd

Now, you move your copy of proll for your JavaStation architecture, along your kernel or piggybacked kernel

image to /tftpboot.

Now, you create of symbolic link from the hexidecimal version of your IP to your PROLL image, and a map

from "HEXIP.PROL" to your real kernel image. If you are using "Embedded−Root" option, you point to your

"Embedded−Root" Filesystem plus Kernel image. If you are using the "NFS−Root" option, you need to point

to the normal "vmlinux.aout" image, plus have a separate map of IP−>nfsroot location. For sake of

completeness, you might also want a "HEXIP.SUN4M" −> "HEXIP" map, as that is the custom way of

dealing with net boot situations with the Sun.

Example for java01 booting from "NFS−Root":

$ ls −ld /tftpboot
