Andrew,
It looks like tftp cannot find the boot kernel. The way this works is
that the client broadcasts on the local LAN looking for a dhcp server.
The DCHP server (192.168.1.1) responds with the IP address for the
kernel server and the name of the kernel. It should respond with a
server ip address of 192.168.2.1, and a boot kernel of
/tftpboot/vmlinuz-2.4.6-1.msc-up. Then the client should tftp the
kernel over the network from the kernel server, read it into memory and
boot the client using this network boot kernel.
Now, is the kernel actually in /tftpboot on the kernel server
(ESC00)? Assuming that the kernel is actually in the right place, with
the right name, I would suspect that either dhcp or tftp is failing.
You can try to tftp a file from ESC00 to ESC00 (tftp to itself) by just
typing in the tftp command, and giving the ESC00 hostname. This will
tell you if tftp is happy.
On your dchp server, you might want to kill dhcp and restart it with
the -d flag, for more debug information, as in:
/usr/sbin/dhcpd -d5&
Also, with dhcp errors, you should see the cause in the /var/log
messages file.
After you take a look at tftp and the dhcp messages, please post again.
best, Rich
