Summary
This document describes
an architecture and configuration techniques for creating an Embedded
Terminal Server (ETS) that provides:
1. Load
balancing and fail-over capabilities for new and existing LTSP installations.
2. Samba file and printer sharing in addition
to Domain Authentication.
3. Enterpise
Integration for legacy Windows applications (using Wine) and Linux natives such as
Evolution,
Mozilla and OpenOffice.
4. openMosix for computationally
intensive and supercomputing applications.
5. An easy to configure
firewall
for monitoring and managing network traffic on all ETS interfaces.
6. A Disaster Recovery Procedure
in the event of catastrophic single server hardware failures.
7. A Soft Fail-over
Procedure that allows individual servers to be removed from
service for normal maintenance.
8. A remotely accessible, comprehensive and
secure administration
system that minimizes the need for command line configuration.
9. A process
that lends itself to automation and the rapid deployment of
additional systems, once the initial ETS is configured.
10. A prototype and template for a highly integrated,
CD bootable distribution that is compliant with the Tools Architecture.
Other then the addition
of a second server, the method described achieves these results
without adding significant cost or runtime complexity to an existing
LTSP system. The implementation provides the architectural features
of both a computational and high availability cluster and would be
suitable for small home/office, educational, institutional and enterprise
applications where low cost, good reliability high performance are
required.
