Open Source Linux System Shells

FLoM is a free open source distributed lock manager that can be used to synchronize shell commands, scripts and custom developed software. When used in a shell environment, FLoM manages process synchronization in the same way that "nice" manages process prioritization. Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication.

Banshell is a tool to scriptably execute commands on a remote machine. It was designed with the goal of increasing security by only allowing a specified set of commands to be executed.

GXP is a parallel/distributed shell, plus a parallel task execution engine that runs your Makefile in parallel on distributed machines. Very easy to install (no need to compile. install it on YOUR machine and use it on ALL machines).

PuSSH is Pythonic, Ubiquitous SSH, a Python wrapper/script that runs commands in parallel on clusters/ranges of linux/unix machines via SSH, ideally where SSH is configured to use Kerberos, RSA/DSA keys, or ssh-agent as to avoid password authentication.

Sensorware is an implementation of mobile agent environment targeted at wireless sensor network.

[Now hosted on Github.] A shell written in Ruby that makes it easier to work with clusters of *nix hosts. The shell allows you define groups of servers and commands that can be executed on the servers. As of right now, all communication is performed

WOOP(c) is an Open-Source Software Architecture.

central-ssh (cssh) is a Perl program that allows systems administrators to run multiple arbitrary commands on multiple arbitrary hosts from one central host. Straight CLI or config file can be used.

This tool lets you login with SSH to a group of machines and interact with them as if they were one machine. Each command that you enter is run in parallel on all machines in the group. The output from each machine is printed separately.

The program `pexec` executes parallely the given command or shell script on the local host or on remote hosts, while some of the execution parameters, namely the redirected standard input, output or error and environmental variables can be varied.

PyDSH is a remote administration tool, consisting of pydsh and pydcp. Pydsh allows you to run a command on multiple hosts in parallel over RSH, SSH or Telnet, OR manage your SSH public keys. The pydcp command allows copying files to/from multiple hosts.

A highly modular client remote/web services library written in Python supporting multiple protocols and transports through a unified interface. All modules are as independent as possible from each other to ensure high re-usability.

N-stage worm propagated via SSH. It executes commands in a given list of hosts and copies files to them with rsync. The paths for its propagation to the cluster are configurable. It offers a scalable/reliable transport API thanks to its adaptive algorithm

xlayout is a terminal based utility to get and set information about X11 windows and the pointer. Its designed to be easily integrated into bash shell scripts and takes advantage of the X11 protocol to allow it to access remote X11 desktops.
