Free 2.5 software for linux

mony is an ICMP monitoring tool designed to be very flexible, scalable, and fast.

What does this program:
reads a configuration file (which can be reread on SIGHUP receival) and tests IPv4 devices
uses O_NONBLOCK so it should be completly non-blocking
programs the tests so there is no flooding effect (if we have to test 10 hosts in 10 seconds we send a test each second)
uses SO_TIMESTAMP for very fine RTT precision
has a modular structure so it can be very easy to change/add new db layers (used for the effective storage of the gathered data) or proc layers (layer which implements the method of gathering/making statistics from the tests)
has a fping-like mode when it reads targets from stdin, runs in foreground, dumps stats to stdout and exits

Installation
./configure
Edit Makefile (if neccesary, but it should work unmodified), and run:
make

Then (as root if needed):
make install
(for installation just copy "mony" to whether location you like)

NPI is a simple calculator that supports Reverse Polish Notation, devised by Jan Lukasiewicz in the Twenties to allow evaluation of mathematical expressions without brackets. NPI calculator supports completion and command history.

In the Twenties, Jan Lukasiewicz developed a system of formal logic making it
possible the mathematical expressions to be indicated without brackets while
placing the operators avant (notation of prefix) or after (notation of suffix)
the operands.

The notation of suffix is named Polish notation reversed (RPN = Reverse
Polish Notation) in the honor of Lukasiewicz.

With this program you will be able to calculate maths expression in the Unix
shell using the RPN notation and with historic and completion support.

Kbtv project is a TV viewer for FreeBSD/KDE mostly written in Python. It uses the PyQt/PyKDE3 bindings, SWIG, and SDL, and supports BrookTree/Connexant BT8x8 (bktr) and Phillips SAA713x (saa) based analog TV cards as well as Philips compatible USB webcams (pwc).

Kbtv is hosted at http://freebsd.ricin.com/kbtv as well as on Sourceforge at http://sourceforge.net/projects/kbtv

DUMA (Detect Unintended Memory Access) stops your program on the exact instruction that overruns (or underruns) a malloc() memory buffer.
GDB will then display the source-code line that causes the bug. It works by using the virtual-memory hardware to create a red-zone at the border of each buffer: touch that, and your program stops.
DUMA project can catch formerly impossible-to-catch overrun bugs. DUMA is a fork of Bruce Perens Electric Fence library.
Enhancements:
- Minor bugfixes for MinGW, Mac OS X and Windows in the test environment.
- A new environment variable DUMA_REPORT_ALL_LEAKS to avoid many false leak reports in broken environments.
- A new debug helper function duma_alloc_return().
- The documentation/README have been updated.
