Free priority health software for linux

System Health Monitor for Linux is a handy python program that will setup your system to generate RRD Graphs of network interface traffic, system load, memory usage, disk space and inode usage and graphs of the number of running processes.

System Health Monitor features a user-friendly interactive configuration mode and auto-generated html pages. Just point your web server to the health_html directory to get an overview of the status of your machine. You can see examples of it in operation here on my machine and on KPLUG.org

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you dont want they eat too much cpu.

cpulimit project does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

issPolicy is a free open-source utility for converting an ISS RealSecure Network Sensor and ISS Proventia Inline Appliance Policy to a static HTML file.
Written in Perl, issPolicy allows for granular parsing of ISS RSNS and ISS Proventia policies (also refer to the "support" section), and supports a wide variety of features (see "features" section) allowing the HTML generation to be customized based on different policy parameters.
Main features:
- issPolicy automatically detects whether the policy is a ISS RealSecure Network Sensor or ISS Proventia Inline Appliance policy and generates a static HTML file based on the policy type and its features.
- issPolicy extracts the following information from the ISS RealSecure Network Sensor Policy:
- Signatures Policy (Signature Name, Signature Description, Signature Status, Signature Priority, Configured Responses, Logging Type)
- IP Filters Policy (Filter Name, Filter Description, Filter Status, Protocol, Source Address, Source Port, Destination Address, Destination Port)
- Event Filters Policy (Filter Name, Filter Description, Filter Status, Filtered Event, Source Address, Source Port, Destination Address, Destination Port)
- issPolicy extracts the following information from the ISS Proventia Inline Appliance Policy:
- Signatures Policy (Signature Name, Signature Description, Signature Status, Signature Priority, Configured Responses, Logging Type, Drop Options, DynamicBlock Options)
- IP Filters Policy (Filter Name, Filter Description, Filter Status, Protocol, Source Address, Source Port, Destination Address, Destination Port)
- Event Filters Policy (Filter Name, Filter Description, Filter Status, Filtered Event, Source Address, Source Port, Destination Address, Destination Port)
- issPolicy contains various useful options allowing for a tailored HTML Policy file to be generated, based on one or more of the following criteria:
- Signature Policy Criteria:
- Whether signature is enabled or disabled
- Based on signature priority (High, Medium, or Low)
- Whether drop is enabled [only on ISS Proventia Inline Appliance Policies]
- Based on drop options (ConnectionWithReset, Connection, or Packet) [only on ISS Proventia Inline Appliance Policies]
- Whether dynamicblock is enabled [only on ISS Proventia Inline Appliance Policies]
- Based on dynamicblock options (IsolateTrojan, BlockWorm, BlockIntruder) [only on ISS Proventia Inline Appliance Policies]
- IP Filter Policy Criteria:
- Whether IP filter is enabled or disabled
- Event Filter Policy Criteria:
- Whether Event Filter is enabled or disabled
- issPolicy uses an "API" structured format, pushing the entire policy to hash arrays, allowing the possibility for other output methods to be developed (CSV, XML, etc...)

PHD Help Desk provides help desk registry and follow-up software.
PHD Help Desk is software conceived for the registry and follow-up of help desks incidents. Registry of incidents allows classification in two levels (type and subtype), the state of the incident, a description, ticket assignment and priority, historical registry, and an audit.
Information can be reported in consultation format, to give reports or export the information for later processing in a database or spreadsheet.
Enhancements:
- Now the operators belong to a sector, in the same way that the users belong an area.
- The database update proccess will insert the sector table with the areas that belong to the operators in version 1.21.
- The ticket is now initialized as "private" by default.
- Only the operators can change this state.
- Two bugs in the support request that prevented the input of the request into the ticket database were corrected.

PKAudio library is a high performance signal/audio processing library that allows stream objects to be created and mixed without interrupting the main stream of audio.

The core library runs in pkaudiod, an executable that runs with realtime or high priority, and a single client can communicate with it via a tcp socket.

A python client is provided, and can be used to write clients in other languages if necessary. The API is small and the protocol is simple.

Installation:

There are two parts to pkaudio: the pkaudiod daemon executable and the python module to communicate with it. The daemon is written in C++ and is configured and compiled like and other make program. To install everything, all you have to do is use the install.py python script like any other extension module. Here are the simplest install instructions:

cd < source dir >
python install.py [-h]

Usage:

If Jack support is compiled into pkaudio, make sure you start the jack daemon before running pkaudiod. If you dont, there will be no audio output. You can start the jack server with at least something like this (-r 44100 is required):

jackd -d alsa -r 44100

The pkaudiod executable is installed in your path and can be executed explicitly from the command line, or implicitly with the python module:

pkaudiod --realtime

The "--realtime" option tells pkaudiod to run with realtime priority, or the highest priority possible if realtime shceduling is not available in the kernel. Most systems will only allow processes to be scheduled with realtime priority if they are executed by the superuser "root". If you want to run the daemon with realtime priority as a normal user, you have to set the owner of the file to root, and the suid bit to on, like this (this is automatically done in the install.py script):

su
chown root `which pkaudiod`
chmod +s `which pkaudiod`

The daemon will tell you if it is running with realtime priority, or if it is running with increased priority.

Using the Python Module:

A good way to learn how to use the python module is to look at test_unittest.py. But, the following code will start the pkaudiod daemon as a child process and play a wav file:

import time
import pkaudio
pkaudio.connect(startserver=1)

sid = pkaudio.createModule(Sample,
/home/ajole/wav/loops/Document 1.wav)
sample = pkaudio.getModuleInfo(sid)
mixer = pkaudio.getMainMixer(0)
pkaudio.getModuleInfo(mixer)
pkaudio.connectToMixer(mixer, sample[outs][0])
pkaudio.setProperty(sid, playing, pkaudio.TRUE)
pkaudio.setProperty(sid, looping, pkaudio.TRUE)
time.sleep(100)

Fortunately, all of this can be accomplished with the higher-level PKAudio module:

import time
import PKAudio

PKAudio.start_server()
d = PKAudio.Driver()
s = PKAudio.Sample("/home/me/my.wav")
m = d.getMixer(0)
m.connect(s.outputPort())
s.play()
while not s.atEnd():
time.sleep(1)

The Aurora Project is an attempt to create a new generation of Linux distributions. It will try to break free from old patterns and establish Linux as a serious world player.
Currently, Aurora Project consists of the Aurora Desktop Environment which, unlike most other Linux-based desktop environments, dont attempts to accomplish everything but to remove the focus from system configuration and desktop customizing by creating an easy-to-use out-of-the-box intuitive and beutiful desktop experience.
The UI is (for now) somewhat Microsoft Windows-inspired. I am satisfied with the general layout of the panel and start menu, currently I am busy designing the core functionality of the desktop with the panel as my number one priority. Also there is the session manager, the desktop manager and the shared library.
The Aurora Project currently consists of two major components - the panel and the shared library.
Main features:
- Windows-like user interface with a start menu.
- Freedesktop-compliant application menu (compatible with GNOME and KDE).
- Frequently used applications are easy to access.

Rconfig is intended to manage configuration files across heterogenous groups of machines. The configuration for each machine is determined by a set of rdist trees based on the various tags such as OS, hostname, and architecture.

Files in more specific rdist trees take priority. A basic setup would consist of a common directory, and then optionally one directory per machine in order to override any of the files in the common area.

Remote configuration requires passwordless root RSH/SSH from a host with direct access to the rconfig basedir. Target machines will require rdist but not rconfig installed.
