Free analysis tools software for linux

Net::Analysis are modules for analysing network traffic.

SYNOPSIS

Using an existing analyser:

$ perl -MNet::Analysis -e main help
$ perl -MNet::Analysis -e main TCP,v=1 dump.tcp - basic TCP info
$ perl -MNet::Analysis -e main HTTP,v=1 dump.tcp - HTTP stuff
$ perl -MNet::Analysis -e main Example2,regex=img dump.tcp - run an example

Writing your own analyser:

package MyExample;
use base qw(Net::Analysis::Listener::Base);
# Listen to events from other modules
sub tcp_monologue {
my ($self, $args) = @_;
my ($mono) = $args->{monologue};
my $t = $mono->t_elapsed()->as_number();
my $l = $mono->length();
# Emit your own event
$self->emit(name => example_event,
args => { kb_sec => ($t) ? $l/($t*1024) : N/A }
);
}
# Process your own event
sub example_event {
my ($self, $args) = @_;
printf "Bandwidth: %10.2f KB/secn", $args->{kb_sec};
}
1;

ABSTRACT

Net::Analysis is a suite of modules that parse tcpdump files, reconstruct TCP sessions from the packets, and provide a very lightweight framework for writing protocol anaylsers.
__top

I wanted a batch version of Ethereal in Perl, so I could:

- sift through parsed protocols with structured filters
- write custom reports that mixed events from multiple protocols

So here it is. Net::Analysis is a stack of protocol handlers that emit, and listen for, events.

Radar Tools in short RAT is a small collection of tools for processing SAR (synthetic aperture radar) remote sensing data, packed together in a nice graphical user interface.
Our motivation to start the development of RAT is that modern remote sensing software like Erdas Image or ENVI include only some basic SAR functionality. Advanced algorithms have to be implemented by oneself.
So we descided to start the development of RAT. RAT should bring modern SAR algorithms to a wider user-base by simplifying in particular the data handling and processing of complex SAR data.
RAT is planned as an ongoing community effort, i.e. there will be no final version with a certain functionality. It is our idea to include more and more SAR tools in future and to make them freely available to the scientific community.
We of course also hope for external contributions. Because of this, the programming interface of RAT is kept quite simple and adding own functions is quite easy. Function templates are included in the distribution and a step-by-step description of how to program a RAT module will appear soon in the documentation.

nwbintools is a machine code toolchain containing an assembler and various related development tools. The project will thus be similar to GNU binutils, but no attempts are made to duplicate its functionality, interfaces, or organization.
nwbintools has been under development (on and off) since January 2007. It was written from scratch in C, and version 0.1.1 has just been released under the (revised) BSD license. Full source code is available from the download page.
At present, the tool collection only consists of the assembler - nwasm - and a simple program to dump some basic ELF object file information. However, in the future nwbintools is probably going to be extended with a new linker, disassembler, and other binary file analysis tools.
nwasm is currently x86-only, 32bit-only, and ELF-only. There are lots of other bugs and limitations as well. See the bugs page for details. The current goal is to get nwasm to work well with the code generated by the nwcc C compiler, which already works to a considerable extent because that code is very simple and doesnt use many obscure x86 features.
Hopefully future releases will support the complete x86 instruction set as well as multiple other architectures, and allow for seamless cross-assembling.
Enhancements:
- This release extends the assembler with support for most instructions from x87, MMX, SSE, SSE2, and SSE3.
- However, support for various system-level and post-486 instructions is still missing.
- Various critical bugs related to labels, relocations, and wrong section sizes were fixed.
- Performance has been doubled.

Analysis of Reinforced Concrete Elements will assist its user to find out capacity of various Reinforced Concrete Structural Elements.

The following professionals are the target audience:

Structural Engineers
Civil Engineers
Architect
Builders

Installation:

The software is web-based, so you need web-server (Apache) running with PHP. The installaton is very simple. If your document root is /var/www/html , then on uncompressing downloaded compressed file in this "document root", the URL for ARCE application become: http://YourWebSite/arce/

WaveTools is a library consisting of 8 programs for manipulating mono WAV Files which I have written for an audiology project at the Technical University of Vienna some years ago as a toolbox for generating and preprocessing small test samples, so this is probably not for making music with (unless youre doing some real hardcore Techno), but if you want to write your own effect filters or sound analysis tools and dont want to mess around with format conversions or standard input filters, or if you just want to arrange some WAVs for your voice modem, you might find this useful.
WaveTools have been developed under Linux/gcc, but should compile on any platform which has an ANSI C compiler (except wview, of course).
Enhancements:
- Dropped binary DOS support (due to lack of DOS compiler; you can still try to build your own DOS binaries if you have a sufficiently old watcom compiler available.)
- fixed bug in wcat.c when converting to lower sample rates
- Dokumentation is now in PDF Format (still German only, though)
- If you have trouble compiling, try deleting the wview entry from the exec: tag in the Makefile. Unless youre into computer archeology, svgalib should be really obsolete by now.

IRRToolSet is a set of policy analysis tools, written in C++. IRRToolSet is designed to run under UNIX, using Tcl/Tk for graphics.

Main features:
RtConfig
- analyzes the routing policies registered in the Internet Routing Registry (IRR) and produces router configuration files;
CIDRAdvisor
- suggests safe cidr aggregates (i.e. those that do not violate any policy constraints) that an Autonomous System (AS) can advertise to each of its neighbour ASes;
peval
- low level policy evaluation tool that can be used to write router configuration generators;
prtraceroute
- prints the route and policy information packets take to a network host;
prpath
- enumerates a list of paths between Autonomous System and specified destination;
