Free runs house software for linux

Chungles is a file-sharing program for local networks that runs on any platform.

More, its a file-sharing program that utilizes ZeroConf (JmDNS libraries) for computer detection and shares files easily about platforms with simple drag ndrop.

The GUI is done in SWT (allowing native graphics) and the program is written in Java.

PShutter lets you firewall off ports such as ssh, and selectively enable access with a one-time password.
For example, if you want to log into the server from a friends house, you pull out a list of one-time passwords and point the web browser at a URL that contains one password. That tells the server to allow ssh connections from your friends IP address for five minutes. Connections made in that period will stay up indefinitely.
IPShutter is written in Perl language. It requires ipchains - on 2.4 kernels, ipchains can be loaded as module. IPShutter must run as root.
You may need to modify the first line of IPShutter to point to where Perl5 is located on your system.
Enhancements:
- Version 0.2 - Sat Sep 28 14:55:03 CDT 2002 - Moved configuration options to /etc/ipshutterrc and fixed daemonization.

IPC::Run::Simple is a simple system() wrapper.

SYNOPSIS

# Run a command and check whether it failed
use IPC::Run::Simple;
run("echo Hello, O Cruel World")
or die "Command failed";

# Describe the failure
use IPC::Run::Simple qw($ERR);
run("echo Hello, O Cruel World")
or die "Command failed: $ERR";

# Use the :all tag instead of explicitly requesting $ERR
use IPC::Run::Simple qw(:all);
run("echo Hello, O Cruel World")
or die "Command failed: $ERR";

# Die with error message if command does not return 0
use IPC::Run::Simple qw(:Fatal);
run("echo Hello, O Cruel World");

# Allow other exit values without dying
use IPC::Run::Simple qw(:Fatal);
run(command => [ "echo", "Hello, O Cruel World!" ],
allowed => [ 1, 2, 5 ]);

This module is intended to be a very simple, straightforward wrapper around the system() call to make it behave more like other builtins.

run() will return a true value if the command was executed and return a successful status code, and false otherwise. The reason for the failure will be stored in the $IPC::Run::Simple::ERR variable (which is just $ERR if you import either $ERR or :all). The description of the reason was pulled almost directly from the system() documentation.
Optionally, you can import the :Fatal tag, which will cause run() to die() with an appropriate message if the command fails for any reason.

If you wish to allow nonzero exit values but still want to trap unexpected errors, you may use an expanded call syntax. Call run() with a set of key=>value pairs. The two implemented keys are command (an array reference containing the command to run) and allowed (an array reference of exit values that are allowed without causing run() to return false or throw an exception.)

Poissonrun runs a given command statistically once every T seconds. The program can be run at any given time, but on average, it is every T seconds.
The random process is based on the poisson distribution.
Installation:
./configure
make
make install
Enhancements:
- This release adds new methods for specifying probabilities and time intervals, improves documentation, and adds a feature for having multiple commands in a running state simultaneously.

Chaos Caverns is a Manic Miner style retro game.

Retro style platform game in a similar style to Manic Miner. Collect the items, avoid the nasties and get to the exit before the time runs out.

Instructions for creating custom levels provided.

rwdshell uses the RubyWebDialogs GUI to run shell commands in a Web browser. It uses the rwdtinker framework for removal and installation of applets.

You have a Ruby eval screen, a shell command line, and a shell script runner. You can edit scripts and run Ruby scripts.
