Hello, I have been testing an XS. We are in NY and the server is in Boston. I have set the Mesh Server on the XOs (in the Control Panel) for the server's URL, and edited /etc/hosts on the XOs to point toward the server's IP address. The devices connect just fine, and I can collaborate on activities between some machines. I am noticing the following things: 1. In the Neighborhood view on the XOs, different devices seem to drop off at irregular intervals. I don't understand why this is happening. 2. Even after a device has been shut down, it still appears in the Neighborhood view on the other devices until they are restarted. 3. I don't' see all the devices in the Neighborhood view at any one time. All of this seems different that how I understand how XS is supposed to work. So, some questions: 1. Is there some timeout function on the server? If so, can it be customized? 2. Is there any limit to the number of connections made to an XS from one IP address? I am thinking that since these devices are all coming from my school, they are all leaving the building with one IP address. 3. If there is such a limit, can anything be done about this? Thanks. My plan is to deploy 150 machines in the next two weeks, so any help will be greatly appreciated. Gerald
