There are a number of XO deployments possible in the Boston metro<br>
area sometime next spring. My understanding is that OLPC does NOT<br>
want to run these deployments, but is interested in having them happen<br>
so there are deployments local to the Cambridge office for test<br>
purposes. As a result, the local XO users group (OLPC_Boston) has<br>
been asked to help out. As my background is in system administration,<br>
I offered to look into possible XS server deployments at the same<br>
time. Even though I've been on server-devel since June; I'm still not<br>
sure to what extent an XS would be useful in these circumstances.<br>
</blockquote><div> </div><div>Bill, at Sugar Labs we are working on taking the olpc server technologies beyond the xs:) We would greatly appreciate your help. I have forward this message to Iaep.<br><br>A good place to start contributing is <a href="http://sugarlabs.org/go/DeploymentTeam">http://sugarlabs.org/go/DeploymentTeam</a> the deployment team is doing some good work with small scale deployments.<br>

As I see it, at this point an XS provides:<br>
<br>
1. XO backup service (ds-backup)<br>
2. Activation service? (probably not needed since XOs will be G1G1)<br>
3. Support for > 20 networked XOs (ejabberd?)<br>
4. Moodle server (not clear what this means in terms of funcionallity)<br>
<br>
Is that correct? Is much going to change by January? For a<br>
deployment of say 20-30 XOs in one location, does it even make sense<br>
to have an XS?<br>
<br>
Another issue is that reusing available resources (pre-existing<br>
wired/wireless hardware, dhcp/dns/web proxy/filtering services) would<br>
be very helpful. Even if pre-existing services are inferior to what<br>
an XS might provide, for political reasons in a small deployment, it<br>
is probably better fit into a framework with which local IT<br>
personnel are comfortable. Unfortunately, my impression is that the<br>
current XS images are somewhat brittle in terms of assuming they<br>
control all of the networking services and as well as requiring<br>
specific IP numbering of various interfaces, control of DNS/DHCP/NAT<br>
routing/etc.<br>
<br>
I understand the need to provide turn-key software for locations<br>
where there isn't anyone who understands networking. However, I find<br>
myself in the situation where even though I know about netmasks, DNS A<br>
records, etc.; I have no idea how much of the higher level<br>
infrastructure on the XS requires leaving things as they are. For<br>
example, can I have an XS with a single Ethernet interface? I think I<br>
saw something in a config file somewhere that suggested this (doing<br>
DHCP on the Internet facing interface), but I can't find any mention<br>
of this anywhere on the wiki. What if I want DHCP/DNS to be handled<br>
by something other then the XS, but do what the other services? Given<br>
the rapid pace of development, it's hard to tell from the wiki pages<br>
what works/used to work/was never implemented/is an idea for the<br>
future/etc.<br>
<br>
I apologize if the above is confused/confusing. Unfortunately, that's<br>
the way I feel at this point. I've got this big ball of string I'm<br>
trying to untangle and I have no idea where to start. Any suggestions<br>
how to get a handle on this would be greatly appreciated.<br>
<br>
Thanks,<br>
