Free fault tolerant software for linux

APLoader stands for Another Postgres Loader, is a front-end to the Postgresql COPY command written in Ruby.

Features include:

fault tolerance
a progress meter
failed batch logs
minimal requirements
a programmable API
excellent performance.

The APLoaderproject is a PostgreSQL Community project that is a part of the pgFoundry.

yagg::Tutorial is a Perl module that contains a tutorial for yagg.

SYNOPSIS

# To use the generator
./yagg -m nonterminals.yg terminals.lg
./output/progs/generate 5

This tutorial will show you how to use yagg, by way of two examples. In the first example, we create a simple logical expression generator from scratch. In the second example, we create a more sophisticated logical expression generator from existing parser/lexer input files, such as those used by YACC/Bison and LEX/FLEX. These examples, plus another more sophisticated fault tree generator are included with the distribution in the examples/ directory.

It is assumed that the reader knows a little about formal grammars. Ideally, the reader would have some experience writing grammars for input to parser generators like YACC and Bison.

VP Toolkit is an Internet client/server C++ library, with support for object threads, stream based socket I/O, a multi-threaded server socket framework, a multi-process fault tolerant server framework, XML, HTTP, etc.

VP Toolkit software is now deprecated in favor of UDK.

To build the documentation you will need SDF, and HTMLDOC. SDF can be downloaded freely from the SDF home page at http://www.mincom.com/mtr/sdf/, and HTMLDOC can be had from

UMLMON is a complete run time environment for User Mode Linux. There is a separate monitor daemon for every VM.
UMLMON project creates the run time environment and starts the VM by executing the UML kernel. The daemon also determines the arguments that are passed to the UML kernel, and includes special support to set up arguments for memory size, virtual disks, virtual network interfaces, and console channels in a convenient way.
UMLMON also includes routines to do certain administration tasks like the creation of disks.
The team UMLMON + UML can be applied in the following areas:
- Server consolidation: Improve the utilization of server hardware, and ease the operation of servers.
- Virtual security zones: Instead of building demilitarized zones (DMZ) with real hardware, it is a cost-effective alternative to set up purely virtual DMZs on a single host.
- Virtual hosting: A cheap version of server hosting is virtual hosting; instead of leasing real computers to customers, virtual machines are used.
- Laboratory nets: By using virtual machines it is possible to build cheap laboratory nets, e.g. to test software in real network environments.
- Training environments: One can use virtual machines for Linux trainings where participants can get true administrators priviledges without any risks.
Enhancements:
- This release no longer call the problematic glibc function getgrouplist, which is often broken (symptom: segmentation fault immediately after starting umlmon).

if_rate measures and prints some statistics about the rate of traffic through network interfaces (like iptraf).
This is a simple program who read from /proc/net/dev and write some real-time statistics about the trafic on interfaces. You can use it free (and without waranties), i hope you will find it usefull and you will use it only for moral .
These are the known bugs:
- some interface drivers have bugs in the update of the counter, not my fault...
- some drivers have time counters updated at more than 1 second interval, to have exact averages you must set an interval much bigger than this interval (example: "./if_rate 10")
Enhancements:
- the rate is more accured, now I use gettimeofday() for exact time measuring.
- more space for gigabit counters
- accept argument - number of seconds between counters is settable

Waveselect was first thought of as a replica of the Windows XP wlan-connection tool. The project makes it a snap to discover local wlans, and connect to them.
It depends on QT-3.x (3.3.3 was used to develop it), and wireless-tools (iwlist, iwconfig). It should work with every card that works with wireless-tool. Use of the great KNemo-tool: ( HTTP://kde-apps.org/content/show.php?content=12956 ) as a companion is recommended, for extra comfort.
Future releases of waveselect will support more features, as long as it can be implemented while still keeping a simple and easy GUI.
This tool must be run as root, unless your user have access to change driver-parameters with iwconfig, and start dhcpcd.
Main features:
- Profile-creation for often used APs (home/work/school/etc)
- Automatically roaming between APs defined by a profile
- Integration with kismet/gpsd/mysql, for showing ESSIDs kismet have previously decloaked.
- Support alternative dhcpd-clients other than dhcpcd
- Support for non-dhpcd networks. Letting the user specify ip, gateway, dns, proxy, etc. manually.
- Configure-dialog for specifying paths etc.
- KDE integration (KDE-classes, KDE-systray)
Enhancements:
- GUI improvements. Options are no longer available if no network is selected. Also beautify the "scan-results" if no networks are found.
- Do an "ifconfig up" on the selected device before scanning.
- (some?) cards using the madwifi-driver does not return scan-data unless this is done (reported by TMS)
- Instead of killing all dhcpcd instances before associating, check if the /var/run/dhcpcd-.pid exists. If it does, get the pid of the cards current dhcpcd-process from this file, and kill only this process. If file does not exist, assume dhcpcd is not running for the card. (reported by TMS)
- This time, it handles a notebook with several wlan-cards better.
- In fact, it handles them at all.
- Improved parsing once again to make it even more fault-tolerant.
- Dont know about any way to segfault it now. But if you find one, be sure to mail me and let me know.
- Manage encryption-settings better. It will now manage to set four different encryption keys. You select which one should be the transmitted key, by selecting the key you want to be active in the "key index" combo-box before pressing associate.
- The "security-mode" option was actually connected to code this time, so it will now have effect.
