drbssh

A protocol implementation for Distributed Ruby (DRb), supporting SSH-connections.

Usage

	DRb.start_service 'drbssh://'
	remote = DRbObject.new_with_uri("drbssh://remote/")
	remote.eval('1+1')

	remote = DRbObject.new_with_uri("drbssh://remote/path/to/ruby")

Description

drbssh makes it possible to create DRb-connections via SSH, with support for bi-directional communication. In contrast to other DRb protocols, DRbSSH requires that a local server is started before creating DRbObjects.

A newly-created DRbObject pointing at a remote server will be pointing at an instance of Binding, representing the top-level of a newly-started Ruby interpreter. The only interesting function exposed is eval.

Development

Uses a Vagrant VM with an Ubuntu-installation to serve as the remote end-point in tests.

TODOS

• Use Net::SSH if installed/possible?
