Free caching appliance software for linux

rPath Appliance Agent project is an extensible application framework for the administration of appliance devices through a web-based user interface.
The framework is comprised of individual component plugins which offer specialized functionality, such as a message log interface, user account preferences, system updates, and entitlement management capabilities.
You can also develop and add plugins to the rAA framework, extending capabilities and functionality for your specific requirements.
To set up your environment for developing rAA, untar the devel.tar.bz2 tarball in the docs directory into your development directory. It should contain the following files:
- README.devel:
this file.
- dev.cfg:
configuration for the development environment.
- raa:
symbolic link to the rAA installation, usually
/usr/lib/python2.4/site-packages/raa.
- raa-service:
used by the startup script for the rAA service daemon.
- raa_service_dev.conf:
configuration file for the rAA service daemon. This contains a pluginDirs
configuration option. Change or append to its value to add additional
directories in which you are developing plugins.
- raa-web:
startup script for the rAA web layer.
- start-raa-service.sh:
startup script for the rAA service daemon.
Enhancements:
- Enhancements to the backup plugin, and a new plugin has been added to allow users to upload new SSL certificates for rAAs Web servers HTTPS connections.

RtspProxy is a proxy server for multimedia streaming services based on the RTSP protocol.
The current version is a complete rewrite from scratch in Java of previous versions based on C++. The goal is to build a robust and scalable system usable in production environment.
The proxy is based on an asynchronous network framework, Apache MINA , which is built on Java NIO. This framework does permit to RtspProxy to handle high loads and concurrent users.
RTSP Caching Proxy is a proxy server that works with the RTSP protocol in multimedia streaming reproduction. RTSP (Real Time Streaming Protocol) is an emerging protocol for "session initiation" scopes, its purpose is to establish the conditions of an audio-video streaming session. The streaming data is then sent over other channels using other protocol such as RTP (Real Time Protocol).
Using a RTSP proxy does permits to access multimedia content without the need of being directly connected to the internet, for example being behind a corporate firewall.
Enhancements:
- A preliminary implementation of the IP address and host name filter was added.
- The Windows startup script was fixed.
- Session data is properly cleared when a session is closed.
- Only a UDP port pair is used for all RTP/RTCP packet handling and sending for all the connected clients.

srcat project can retrieve data from disks once used in a Coraid SR (SATA+RAID) appliance.
Enhancements:
- This initial alpha release retrieves data from disks that previously composed a clean RAID 5 in a Coraid SR.
- The retrieval takes place on a POSIX platform, independently of the SR unit.
- Support for RAID arrays missing disks and for levels besides RAID 5 has yet to be added.

Copix is a multi-purpose framework for PHP Web applications. It features a multi-layered structure (GUI, services, and database access) and an advanced caching system based on plug-ins (Smarty, internal, or others).
Many other components are also integrated, including a calendar, mail sender, and a forum.
Enhancements:
- A wiki, cache system, and log system were added.
- Authentication is better and simpler.
- Copix 3 works with PHP 5 and PDO (MySQL, SQLite, Oracle, and others).
- Lot of major changes were done.
- The module system is very useful and simple.

cache4j library is a cache for Java objects with a simple API and fast implementation. It features in-memory caching, a design for a multi-threaded environment, both synchronized and blocking implementations, a choice of eviction algorithms (LFU, LRU, FIFO), and the choice of either hard or soft references for object storage.
Main features:
- in memory caching
- design for multithread environment
- two implementation: synchronized, blocking
- eviction algorithm LFU, LRU, FIFO
- for store object can use strong or soft reference
- available under the BSD license
Enhancements:
- Initial release of cache4j.

CacheFu is a project which speeds up Plone dramatically.
CacheFu speeds up plone sites transparently using a combination of memory, proxy, and browser caching. CacheFu can be used by itself or with squid and/or apache.
CacheFu generates configuration files for squid or squid behind apache (if you are using apache by itself, no special configuration is needed).
Once you have installed CacheFu, your site should run much faster (~10x faster by itself, ~50x faster with squid).
Enhancements:
- This release aims to address some minor issues with generated configuration, documentation, and version compatibility with Plone and Squid.

wmcapshare is a dockapp to control and manage the HP Capshare Information Appliance.

The goal is to provide a linux replacement for the CapShares own application which HP has seen fit to discontinue.

Why

I got sick of having to deal with the openobex sample application as my only interface to my HP Capshare. So I finally sat down and dealt with it. Also HP recently discontinued the product and no longer support it. I had been using it with windows when I needed to, but the drivers no longer work with Win2K.

What

The HP CapShare is a handheld document scanner. wmcapshare is a dockapp to manage the files you upload

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...)
