Setting up a PXE Boot Server
I've set up a PXE boot server and I'm having a slight snag in the booting process. On the client machine, DHCP renders fine and TFTP seems to begin but then the system hangs. On the server, the error message "Client does not accept options" occurs -- which from reading online is a common message that generally doesn't affect booting. So, I've been doing random troubleshooting but nothing has yielded anything useful. Any thoughts? Thanks.

Once I knew how to set up a unix file so that the num lock would automatically be on after booting up. How exactly is that done?
Unix has final control on the setting of the num lock from off or on to on at the end of the boot up process.
Any help will be appreciated, especially if detailed.

ndbootd
NDBOOTD(8) BSD System Manager's Manual NDBOOTD(8)
NAME
ndbootd -- Sun Network Disk (ND) Protocol server
SYNOPSIS
ndbootd [-s boot2] [-i interface] [-w windowsize] [-d] boot1
DESCRIPTION
ndbootd is a server which supports the Sun Network Disk (ND) Protocol. This protocol was designed by Sun before they designed NFS. ND sim-
ply makes the raw blocks of a disk available to network clients. Contrast this with the true namespace and file abstractions that NFS pro-
vides.
The only reason you're likely to encounter ND nowadays is if you have an old Sun 2 machine, like the 2/120 or 2/50. The Sun 2 PROMs can only
use ND to boot over the network. (Later, the Sun 3 PROMs would use RARP and TFTP to boot over the network.)
ndbootd is a very simple ND server that only supports client reads for booting. It exports a disk that the clients consider to be /dev/ndp0
(ND public unit zero). The disk is available only to clients that are listed in /etc/ethers and have valid hostnames. (Sun 2 PROMs don't do
RARP, but they do learn their IP address from the first ND response they receive from the server.)
boot1 is a file containing the mandatory first-stage network boot program, typically /usr/mdec/bootyy. The layout of the exported disk is:
o block 0: normally a Sun disklabel (but ignored by the PROM)
o blocks 1-15: the first-stage network boot program
With the -s boot2 option, ndbootd will also make a second-stage network boot program available to clients, typically /usr/mdec/netboot. When
boot2 is a filename, that file is the single second-stage network boot program to be served to all clients.
When boot2 is a directory name, typically /tftpboot, ndbootd finds a client's second-stage network boot program by turning its IP address
into a filename in that directory, in the same manner later Sun 3 PROMs do when TFTPing (i.e., if a client has IP address 192.168.1.10,
ndbootd expects to find /tftpboot/C0A8010A.SUN2 ).
When used in this last manner with an ND-aware first-stage boot program, ndbootd serves the same purpose in the Sun 2 netboot process as
tftpd(8) serves in the Sun 3 netboot process.
Any second-stage network boot program always begins at block 16 of the exported disk, regardless of the length of the first-stage network
boot program.
All first- and second-stage network boot programs must have all executable headers stripped off; they must be raw binary programs.
The remaining options are:
-i interface
Only listen for ND clients on interface interface. Normally ndbootd listens for clients on the first non-loopback IP interface
that is up and running.
-w windowsize
This adjusts the window size of the ND protocol. This is the number of 1-kilobyte packets that can be transmitted before waiting
for an acknowledgement. Defaults to 6.
-d Run in debug mode. Debugging output goes to standard error and the server will not fork.
FILES
/etc/ethers
/etc/hosts
SEE ALSO
tftpd(8)
BUGS
Whether or not there is a second-stage network boot program, the exported disk appears to all clients to have infinite length. The content
of all blocks not used by the first- or second-stage network boot programs is undefined. All client reads of undefined blocks are silently
allowed by the server.
