Good morning Chris,<br>
<br>
I don't have any suggestions for you, but I must commend you on choosing<br>
software that aligns with your organization's mission--and what a great one<br>
it is, from what I read on your website. Given how much time we all spend<br>
with our devices and computers consuming and creating content, I think<br>
sometimes we don't understand that the principals our software are<br>
developed with are in some ways the lenses through which we interact with<br>
that technology, and it shapes what we ultimately ingest and create.<br>
<br>

Welcome to the list. I would like to get some more information before I<br>
offer some advice. If you want we could arrange to meet and discuss<br>
these items on IRC instead of continuing an email thread; I leave the<br>
choice to you.<br>
<br>
See my responses below:<br>

How many computers is it installed on? If your fleet of devices is large<br>
you will want to employ some configuration management system to automate<br>
deployment, patches and settings. Managing 30 computers is feasible by<br>
hand (though inconsistencies due to human error are still possible), but<br>
managing 4000 computers by hand is not feasible. Even if you have a<br>
small number of computers using a configuration management tool can have<br>
benefits.<br>
<br>
There are choices like Landscape (1), ZenWorks (2), Puppet (3), Chef<br>
(4), Ansible (5) and Salt (6).<br>

<br>
Using the aforementioned tools for configuration management is one step<br>
towards securing the computing resources since it will ensure patches<br>
are applied. In order to offer more suggestions I would need to know<br>
what your concerns are for securing the computer labs. I do have the<br>
following questions though:<br>
<br>
* Do you have an identity management solution in place (Active<br>
Directory, Open Directory, Novel Directory Services, OpenLDAP,<br>
ApacheDS, 389 Directory Server, OpenDJ)?<br>
* Do you have file servers or other network accessible resources<br>
you need to secure? (keep students away from SchoolTool, etc)<br>
* What operating system is used by faculty and staff?<br>
* Are you concerned about students changing configurations on<br>
computers?<br>
* Do you currently have any ability to collect logs from your<br>
client computing devices and server infrastructure?<br>
<br>
I have 15 years of experience in a K-12 school and currently manage the<br>
core infrastructure (servers, virtualization, disaster recovery, Active<br>
Directory, etc). When I first started I was responsible for everything<br>
from the desktop to the server infrastructure. Based on that I would<br>
focus on configuration management, identity management and logging of<br>
events/activity.<br>
<br>
I would be happy to get deeper in to your particular environment.<br>
<br>
<br>

Nice to read this high-level conversation. Two things I would add:<br>
<br>
1. Consider using LTSP-pnp with Epoptes. This is a great way to address some of the challenges you mentioned (and that I?ve encountered as a 25-year science teacher using 15-20 computers in my classroom). It can work with LDAP/Active Directory.<br>
2. If you do continue the conversation on IRC, please copy/paste the IRC dialog back into this thread so that others can search/find and learn from the problems and wisdom shared.<br>
<br>
Best of luck,<br>
David G<br>

If we use IRC I will post the log or a link to the logs if it is a<br>
logged channel.<br>
<br>
I agree LTSP is one of the tools that can stretch the dollar and manage<br>
a lab. ITALC is another tool that can help.<br>
