Thanks for the information.
I will look into the problem in more detail and report to the list if I
find a viable solution.
Cheers,
Lonnie

Hello All,
Is there a way to build a floppy boot disk for my clients in which I can
specify a specific DHCP server IP?
A dhcp client sends out a broadcast request for network information.
There's no way to direct it to a specific DHCP server.
There are ways to configure your dhcp servers to ignore requests from
unknown clients. That's handy if you have more than one DHCP server on the
same network segment.

Jim, Lonnie... This is a bit from the "other direction" but it is
relevant to this topic and it may help you (lonnie) to solve your problem.
I just finished up the network/VLAN/DHCP/DNS condfiguration for a
client's MITEL VoIP installation.
One of the DHCP options that I needed to set in my DHCP server for these
phones to work was the private option: option-130
Near the top of the dhcp.conf file I added a line to define the new
option to the server:
option option-130 code 130 = text;
Then within the subnet scope the option is given a value of
"MITEL IP PHONE" with the following line:
option option-130 "MITEL IP PHONE";
Mitel IP phones will ignore packets from DHCP servers that do not send
back that option in the DHCPOFFER after the phone's DHCPDISCOVER
broadcast. Is this "secure" by any means... Well, no... But at least the
phone is discerning when it ACKS a dhcp least offering. :)
So, Lonnie, on that boot floppy, you'd need to modify the settings for
the dhcpclient program of your choice to act like the MITEL IP Phones I
described above and configure your DHCP server in a similar manner,
defining a private option. I've never had to do this, so you'll have to
research and report back :)
One last comment on this (and to take it in a completely different
direction of thought): I currently have ONE ~20 station LTSP
installation under my belt for a client. I decided on using the 2nd
ethernet interface on the LTSP server to connect to a completely
separate VLAN where all the workstations live. They can ONLY get a DHCP
address from the LTSP server since their VLAN is not routed, and their
traffic is not hindered by other "normal" network traffic. Also, this
slution is helpful if - in the future - they experience some networking
bottlenecks and LTSP seems slow, I can always apply QoS on that VLAN
with minimal effort. :)
Just a passing thought that might also help you solve your problem,
unless you want to be able to dual-boot your LTSP machines as I suspect.
Hope something I said helps a little. :)
