[UFO Chicago] syncing multiple workstations to one master

You can go either way:  thin(ish) clients with LTSP, or thick clients that have full OS installs.

In some ways, you can trade pain now for pain later, not to mention costs.  Having a single large server for ltsp may reduce your admin costs, but you have to have good hardware.  Or you can go for thick cilents with small "policy server" for your cfg mgmt program.

Without knowing more, I can't say which is right.

You could have the clients connect to a VM 'server', but that means an even larer server, and more complicated management.  The advantage, however, is that you can test new server software, but leave the 'production' system alone in its own VM.

Two other points:

1) If you go the LTSP route, you can start with a small server, and see if that model will work for you.  If performance is a problem, then get better hardware, but use what you have until you can show there's a problem.

2) The thick client model will scale more easily than the LTSP model, since all the 'server' is going to do is feed small policy files, and possibly push larger files around the network occasionally.  Most of the "work" is on the client side, so when/if you double the size of the lab, you probvably won't need a huge new server.

Ah, You're using LTSP--I didn't know that using that before my last email.  That actually makes things a bit simpler, so far as package distribution goes.

We haven't actually built the lab yet. 
First question is do we use the 12 (or so) boxes as clients ? Or install a full blown OS on each box ? 

Whatever we decide to install, the existing g/PXE boot server will make quick work of it. Clients would require a beefy server to connect to. Full blown OSes would require lots of management, unless we use some of the tools suggested.

Next question is, if we use the boxes as clients, to we connect to LTSP or VMs ? 
Probably woulda helped if I started the question like this.......I'm pleading the fifth...on what grounds I don't know , but I'll think of something good.
