Drbd is a block device which is designed to build high availability clusters.
This is done by mirroring a whole block device via (a dedicated) network.
You could see it as a network raid-1. You might need drbd to build Linux based
HA clusters.

Csync2 is a cluster synchronization tool. It can be used to keep files on
multiple hosts in a cluster in sync. Csync2 can handle complex setups with
much more than just 2 hosts, handle file deletions and can detect conflicts.
It is expedient for HA-clusters, HPC-clusters, COWs and server farms.

Trapdoor2 allows remote users to execute local commands by sending 'magic
cookies'. This can e.g. be used to alter local firewalling rules so people can
connect to local services after sending the magick cookie. Trapdoor2 is
implemented as high-secure https server.

SSH-Dist
|
A toolchain for autocreating and distributing ssh authorized keys files (as
well as distributing other files). The created authorized keys files do only
allow logins using the keys from dedicated other hosts. The toolchain also
contains a script to visualize the graph of allowed logins for security
auditing. There hasn't been an official realease so far.

A really short but useful shellscript for connecting to all nodes of a
cluster using ssh (also thru gateways and trapdoors) and sending commands
to all nodes in parallel. It's using DCOP to remote-control a konsole
process with the ssh connections in seperate tabs.

driver for the GNU/Linux operating system that mirrors a disk over
the network onto another node.

making use of multiple CPUs/cores to handle requests of a single connection
in a pipelined fashion.
