My /etc/ltsp/dhcpd.conf looks almost exactly like yours. I think either your nics haven't taken their newer configuration or your dhcp server hasn't gotten it's newer configuration.

Joseph, I can't spot the problem either. And the dhcp3-server package in 11.10 is new to me (dhcp3-server - ISC DHCP server (transitional package)).
But since your error references not being able to process your /etc/ltsp/dhcpd.conf file correctly, consider
1) backing it up and regenerating it
2) checking it's read permissions (ls -l )
3) ensure that it's the correct config file (correct name/correct location)
I'll try to remember to check your dhcpd.conf file against mine when I get to work today.
I think it's unrelated to your dhcp server issue, but make sure you work out your upstream device (eth0) which might require purging network-manager.
And dont' forget to run sudo ltsp-update-sshkeys since you changed your nics.
but maybe you knew all that...

Hey Joseph,
Some things that come to mind...
Are you
using "Network Manager"? it seems that that has a different way of
setting up ip addresses.* For example, I was just trying to set up a vpn
client on my home ubuntu so I could access our district servers.* I
thought I had everything correct but couldn't make it work with editing
the appropriate config files.* So then I tried using
System-->Preference-->Network Connections and got it set up and it
worked BUT it also ignored my /etc/network/interfaces config file!* So
then I had to put further info into this application to get my internet
and static ip back.* Lesson here, read up all you can about the issues
with Network Manager.* I know that I ended up removing it while setting
up the school ltsp server 15 months ago.* So, I'm saying that some other
config file besides /etc/network/interfaces MIGHT be affecting your
setup.* Sorry I don't know more about this.
A common mistake for me is choosing the netmask--I've never
really learned the diff between type A and type B/C etc networks, I
don't remember when I should set this to 255.255.255.0 or 255.255.0.0.
so when nothing else works I try one then the other.* I seem to remember
that a 10.x.x.x would have the latter?* You probably know all this but I
thought I would share it just in case.
When you type the command, "ifconfig" into the terminal, what
do you get?* This give some critical info as to what's happening on each
of your ports.* It would be useful (perhaps for myself or someone who
knows more than I) for you to post the results of ifconfig here.Good Luck!* When it finally works it's sweet!

Hello,
Thanks for your feedback -- I tried mimicking your setting but I still
receive the same error. *I also did make a point to restart every time
I made changes to the configuration files but it also made no
difference.
