Sorry to be so slow, I have been teaching and not working on LTSP.

Between my experimental LTSP server and my experimental client I have a
direct connect crossover cable no hub, now switch; the message on the client
boot screen indicates 100Mbps full-duplex and /var/log/messages on the
server says the same.
The network may be a problem - I am not really clear how different networks
interact. In my classroom I have a server (not the LTSP one) that is
between the school LAN and my classroom LAN. That classroom server has
10.6.44.1 mask 255.255.0.0 on eth0 connected to the school and 192.168.44.1mask
255.255.255.0 connected to a 10/100 switch for 36 computers in my
classroom. All the classroom computers are 192.168.44.x My LTSP server is
192.168.44.57 on eth1 by dhcp from the classroom server and is
192.168.0.254on eth0 which directly connects to the client.

I fixed the long boot process by changing the BIOS to default boot from SCSI
without first trying the other default BIOS settings. The former TFTP
timeout does not seem relevant.
The time out message is what needs to be looked at from LTSP point of

My LTSP server still repeatedly
Dec 12 14:36:14 server dhcpd: DHCPDISCOVER from 00:40:f4:e8:e9:24 via eth0
Dec 12 14:36:15 server dhcpd: DHCPOFFER on 192.168.0.253 to
00:40:f4:e8:e9:24 via eth0
while the client is "Searching for server (DHCP)"
It seems strange to me that in the Service Configuration GUI that the tftp
process is checked and says that xinetd is running -- however the start stop
restart etc. buttons in the tool bar are inactive.
