The XS is installed on x86 -(Intel-compatible) computers. These could be conventional servers such -as rack-mounted computers, purpose-built low-power machines, or even -netbooks. - -The OLPC XS provides additional infrastructure extending the -capabilities of the laptops. While the laptops are self-sufficient for -many learning activities, other activities and services depend on the XS -providing connectivity, shared resources and services. The XS provides -XO machines with network connectivity for backups, anti-theft leases, -web browsing, system, content updates, and asynchronous collaboration -tools such as Moodle. - -Installation -============ - -Two installation options are available: - -1) XS installation CD (recommended): download and burn a CD image, and - use the resultant CD to install the system. See details at - [http://wiki.laptop.org/go/XS\_Installing\_Software\_0.7\#Installing\_from\_CD](http://wiki.laptop.org/go/XS_Installing_Software_0.7#Installing_from_CD) - -2) On top of another system (advanced): install the XS software - packages on top of an existing operating system installation. See - details at - [http://wiki.laptop.org/go/XS\_Installing\_Software\_0.7\#Installing\_on\_top\_of\_existing\_OS\_installation](http://wiki.laptop.org/go/XS_Installing_Software_0.7#Installing_on_top_of_existing_OS_installation) - -The installation is fairly straight forward and requires minimal -configuration after the intial installation to the XS hard drive. - -Configuration -============= - -Configuring the XS involves choosing a server domain name. The hostname -is always 'schoolserver'. So, using a domain name like example.org will -give you schoolserver.example.org. - -The XS has a fairly standard server-style networking setup. The XS -provides DHCP and DNS services to all the XOs connected to it via a -wireless access point. However, if the school already has its own -network running its own DHCP services, the XS networking can be modified -to work with the existing infrastructure. The XS can work with two -Ethernet cards, where one works as a WAN interface, while the other -works as the LAN interface. The XS can also work with a single Ethernet -card where it works as a LAN interface for schools without WAN -(Internet) connectivity. Optionally, such a server can provide WAN -connectivity using a USB-to-Ethernet adapter. - -Services -======== - -Collaboration -------------- - -The XS provides collaboration services across a variety of activities. -When XOs are connected to the School Server, the collaboration is -managed through the server and can be segmented by a classroom or a -group. While the user will not see anything different, the capacity of -collaboration will scale up considerably with a XS in the mix. - -Caching -------- - -The XS uses Squid to cache content locally. At sites where Internet -access is limited, slow or expensive, content caching helps in speeding -up acccess to content by making copies on the XS and serving these up -locally. - -Backup and Restore ------------------- - -The XS provides seamless backup services for each registered XO. The XS -checks to see the backup status of the Journal on each XO and backs it -up incrementally. Once the backups are made, these can be used to -restore a child's work back on her XO. - -Antitheft Controls ------------------- - -Antitheft controls lists all registered XOs in one location. -additionally, this feature offers rescue leases to laptops to -re-activate laptops in case of problems. If a laptop gets stolen, the -antitheft control feature shuts it down. - -Learning Management System --------------------------- - -Moodle is a Learning Management System that provides the teacher with a -way to create a course, manage assignments and administer assessment -using a web-based interface. On the XO, the Moodle LMS is accessible via -the Browse activity. Moodle features include assignment submission, -discussion forums, file downloads, grade books, instant messages, -calendars, news, announcements, quizzes and wiki. - -:author: - -> © Sameer Verma and George Hunt 2012 |
