XS Release Notes

Please read these notes to understand the capabilities and known problems with a particular release of the XS ("XO School server") software. For older release notes, see XS Release Notes archived.

XS 0.7

Read steps to install.

• Rebased onto CentOS 6.2.
• Linux-3.2 backported from Fedora 15 for maximum hardware compatibility
• Supports installation on top of existing RHEL-compatible install (e.g. CentOS), in addition to regular install media
• Interoperates better when run on an existing network - you are no longer required to make the XS 'run' the network.
• Networking setup greatly simplified: no more bonding
• eth0 is now the LAN, eth1 is now WAN. This is the opposite of previous XS releases, aimed at situations where no WAN connection is available (or when running on a previously existing network).
• Active antenna and mesh support dropped.

Known issues/untested items:

• XS-on-XO1 not generated for this release (and XO-1 mesh is no longer supported)
• No tested upgrade path from XS-0.6. Feedback/documentation welcome.

XS 0.6

XS 0.6 was released on 07 October 2009!

1. Download OLPC-School-Server-0.6-i386.iso ,
2. Read steps to install. From XS-0.5.x, the upgrade is easy -- see upgrade notes.

This release provides

• Installation improvements: significantly easier installation and configuration.
• Moodle+XO automagic authentication: using Browse.xo v101 or newer, users autologin to Moodle after registration.
• Better network scalability through Moodle+ejabberd integration Moodle can now control the presence information shown in ejabberd.
• Delegated security: xs-activation now handles lease delegation, making it possible to delegate activation to disconnected or partially connected School Servers.

Notes

• Upgrades: With this release you can now upgrade sanely from earlier version. The steps are:
  1. Recommended: Backup the system! :-)
  2. Edit /etc/yum.repos.olpc.d/stable.repo - set the 'baseurl' of the 'olpc' repo to http://fedora.laptop.org/xs/stable/olpc/xs-0.4/i386/
  3. Run yum -y upgrade
  4. You will have to re-run /etc/sysconfig/olpc-scripts/domain_config <yourbasedomain>
  5. Some new system daemons are set to start on the next restart - either restart the machine or start them manually. The services that need starting should be: incrond, apache
• New installations: there is a bug in Anaconda which prevents it from setting the ownerships and permissions correctly in the /library directory. After installation, execute chown -R xs-rsync.xs-rsync /library/xs-rsync/{pub,tmp,state}
• This release contains the DS-Backup implementation, with a restore facility aimed mainly at the test team. The user-friendly (and privacy-friendly) version of this will be part of Moodle - coming to a build near you soon. For production deployments you might want to disable the restore page. See documentation on this feature here.

• This build requires a minimum of a 5.5Gig hard drive to install -- thanks to Grant Patterson for the kickstart fixes for trac 7241 .
