[K12OSN] ltsp, subnets, dhcpd.conf

[Will Hatch]

Thanks for the quick reply Rob.  You've focused in on one of my problems.  The dhcp is served from the high school, as is dns.  There are no plans to have dhcp served from my building.  I do have two nics installed in the Edubuntu server, because that is the way I previously did it with k12ltsp.  I'm a Educational Technology teacher, so networking is a work in progress.  If I understand correctly, you can't have a dhcp server inside of a dhcp server.  So there is nothing I can do to my Edubuntu server to make things work?

If you want to have thin clients only on subnet 3, then it sounds like 
you should use a single-nic setup.  This means, though, that the K12LTSP 
server will be acting as the DHCP server for the entire subnet.  Make 
sure that is ok, and make sure there is no other DHCP server on that 
subnet.

If you set it up like this, then the K12LTSP server can be located 
anywhere on your subnet and it will work.  Just make sure it's giving 
out the correct IP addresses for your subnet.  Also make sure that you 
define the proper gateway machine in dhcpd.conf.  It will not be the 
K12LTSP server.  It will be the IP address of the Sonicwall firewall. 
Now that I think of it, you'll also need to set the DNS server in 
dhcpd.conf too.

I have Edubuntu with ltsp installed, I have a universal boot floppy written for clients.  But I know I have to do something to configuration files to get clients to boot.
