[IAEP] Sugar on Wireless
The idea of running Sugar on the local network is very appealing. The idea of setting up a server is a pretty daunting prospect. Can I do it? Would I be allowed to do it? etc.. I would have 16 students max running Sugar but there could be another 16 or so in the next classroom. Hmm... I have Sugar on three Macbooks. I removed the sugar labs server address from all three and verified that I could get on the internet. I could not see the other Mac books. Next, I created my own network, got all three Macbooks on the network. Nothing. I verified the network by turning on internet sharing. Still nothing. On Jun 25, 2009, at 4:40 PM, Benjamin M.

Sugar has serverless collaboration that works very well... as long as there isn't too much collaboration traffic for the network to handle. The maximum number of students seems to vary between 20 and 40, depending on wireless network hardware, physical classroom layout, RF environment, etc. The limits are probably much higher for wired networks. In other words, if she is only working with one classroom, she probably doesn't need a server. If the laptops are plugged into a wired network, then a server is even less likely to be necessary. If a server is necessary... that's trickier. Setting up a server is a lot of work. Personally, I think XS as a service would be a great business for some enterprising company (or even Sugar Labs itself, though that seems less likely these days), and a free taster limited to 30 students per school might be just the way to get started. --Ben ___ IAEP -- It's An Education Project (not a laptop project!)

Think of that NAT behaving like new virtual local network, as if your VM was running behind another separate AP. Regards, --Gary Hi, I just double checked this. NAT does not work with local collaboration. It works fine with a collaboration server. Bridged does work with local collaboration. I am looking into using the Export Appliance feature of Virutalbox to preset the network settings. Dave ___ IAEP -- It's An Education Project (not a laptop project!)

Re: [IAEP] Sugar on Wireless
Hi, I'm back home now and checking in. When I was at FOSSED it looked like Macs running under virtual box could not use local collaboration because it doesn't directly see the APs. Is this confirmed? Are there other ideas for getting MacBooks using VirutalBox to collaborate without an XS?

In Virtualbox? If so, one of our Virtualbox experts will have to work with you on network topology issues. (The problem could be that Virtualbox is running the virtual machine behind a firewall, rather than giving it direct access to the local network.) FWIW, I use these network settings. There are a number of different ways to get a working network, but this one seemed closest equivalent to being 'just another laptop on the network'. One thing to note, is that VirtualBox does not represent wireless interfaces specially as wireless interfaces. It just treats them like a wired ethernet connection. No big downsides to this, but you will see the Sugar frame showing a Wired Network icon, and you will not see any wireless access points showing up in the Neighbourhood view – you need to be correctly connect to your network access point over in OS X.

I've not done extensive collaboration tests with the SoaS Strawberry image, but cursory Salut tests with Chat (between a MacBook Pro running the Strawberry VM, and 2 other XO-1s running 0.82.1 connected to my local AP) seems to be working just fine. Each machine sees the other 2 in the Neighbourhood, each can share or join Chat Activities created by the others. Were the VirtualBox VM networks set up correctly?

I would have 16 students max running Sugar but there could be another 16 or so in the next classroom. Unfortunately, it's hard to predict how reliable this sort of setup will be. It depends on how many access points there are, and how they are wired together. It also depends on the radio performance of your APs and macbooks. It even depends on what the walls of your school are made of. However, I would say that there is at least a good chance that it will work. Hmm... I have Sugar on three Macbooks.
