Excerpts from Mikus Grinbergs's message of Sun May 30 09:38:37 +0000 2010: > I've been currently using an Ad-Hoc wireless network (set up by clicking > in an XO's palette at the gray icon in Frame) for testing collaboration. > That network is performing well, and has been reliable. Great!
> But this was on channel 1. Can neighbors (or drive-bys) connect to it? The channel doesn't matter. And yes, as you can see by your other XOs not needing any authentication, everyone can connect to it. This isn't specific to Sugar or the XO. Unlike the XO Mesh, ad-hoc mode is standardised (IEEE 802.11 IBSS) and supported by virtually all devices. There's nothing "obscure" about it (re. "security through obscurity"); at least NetworkManager and iwconfig will list it with all the other (i.e. infrastructure mode) wireless network. I don't know how setting up / discovering networks works on Windows or Mac, so can't tell whether they show ad-hoc ones as well. Unlike Sugar, the Gnome UI for NetworkManager offers enabling WEP/WPA when creating the ad-hoc network, but I don't know how well this is supported by the chipsets (one forum post I stumbled upon suggests that at least a Broadcom one seems to have issues). > And what is my legal liability if they do? IANAL, but given that NetworkManager (which Sugar relies on for doing the actual work) does not enable "connection sharing" (NAT from private network to default route) by default and Sugar does not enable it either you should be pretty safe. If anyone can gain access to any of your hosts via the unsecured network, you already screwed up before. HTH. Sascha -- http://sascha.silbe.org/ http://www.infra-silbe.de/
