Progress on Edbuntu thin client lab

I’m not sure. If I get a chance when I go to school tomorrow, I’ll check it out and see what I can find out from my installation.

Full Disclosure: I used K12LTSP for my lab. It is based on Fedora (or now, CentrOS). If you don’t mind using Fedora instead of Ubuntu, it might be an option as well. It did, in my case, install multiple Desktop Environments, which was nice to play with and find what the kids liked best. http://www.k12ltsp.org

I’ll try to remember to check my lab tomorrow if I get a chance and see what my files look like. I didn’t have this many issues getting mine going-so I’m not certain.

Full Disclosure: I used K12LTSP instead of Edubuntu. That might be an option to consider, in my experience, it had more programs to offer than Edubuntu. That might have changed with the latest Edubuntu release. If you’re not against using Fedora (which is what K12LTSP is based on), its an option. I’ll either be upgrading mine this summer, or switching over to Edubuntu–haven’t quite decided yet.

Ok-I’m sitting in front of my LTSP server right now. Here’s what I have…

First of all, my /etc/dhcpd.conf file is basically empty. Here’s what it says:

#
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#


I actually couldn’t believe that is what it was–until I was able to boot up my other machines (making sure they still worked).

In my experience (it took going through this to remember) - I used this file to tell my clients about specific hardware.

Now…there is this sample file in there as well.

# Sample configuration file for ISCD dhcpd
#
# Don't forget to set run_dhcpd=1 in /etc/init.d/dhcpd
# once you adjusted this file and copied it to /etc/dhcpd.conf.
#

# Apple Specific Settings
# host ws007 {
# hardware ethernet 00:30:65:69:23:60;
# fixed-address 192.168.0.4;
# option root-path "192.168.0.254:/opt/ltsp/ppc";
# filename "yaboot";
# option vendor-class-identifier "AAPLBSDPC";
# }
}


There are also some startup scripts further in to /etc/init.d. You may have to change a setting on one of those to get dhcpd to start.

The 172.***.**.* looks weird to me. LTSP (from my experience) always has used 192.168.0.*** with the server being 192.168.0.254. That could be an issue. I’m not sure if it is different for Edubuntu or not–so that could be an Ubuntu thing.

One other thought, have you been to the official Ubuntu forums and given them your problem? (I’m sure you have–but I figured I’d check) You can also pop on their IRC channel. They’re usually very helpful.

Thanks odometer for the feedback. It helps to see what the DHCPD.config file looks like on a working system.
The 172.16.10.0 is the static address for the server on the network. Our network admin set when he was trying to figure out why id wasn’t working. Although he said the 192.168.x.x is available to use since the school network doesn’t use that IP range. I’m not sure whether or not the rest of the subnet has to be in the same IP range as the server.

I think you’re making the same assumption that I did initially. The IP address of my server at school to the outside world is 10.***.**.***. (I don’t remember exactly). However, the IP address of my server inside my network is 192.168.x.x. On my setup, Eth1 gets its IP via DHCP from the server. Eth0 is a static IP 192.168.0.254.

I’m just speaking from my personal experience. I’m definitely no expert. Basically–I can boot my entire network without plugging my server into the internet. There are times where this is handy–b/c I’m able to keep my kids off the net (when needed). All I do is unplug it from the wall.

However, I’m not sure the IP address is the only issue. It should work either way.

Maybe this link will explain further.

As you can tell, I truly believe in this solution–so I’ll do what I can to help.
