pod2man is a Perl module that can convert POD data to formatted *roff input.

SYNOPSIS

pod2man [--section=manext] [--release=version] [--center=string] [--date=string] [--fixed=font] [--fixedbold=font] [--fixeditalic=font] [--fixedbolditalic=font] [--official] [--lax] [--quotes=quotes] [input [output] ...]

pod2man --help

pod2man is a front-end for Pod::Man, using it to generate *roff input from POD source. The resulting *roff code is suitable for display on a terminal using nroff(1), normally via man(1), or printing using troff(1).

input is the file to read for POD source (the POD can be embedded in code). If input isnt given, it defaults to STDIN. output, if given, is the file to which to write the formatted output. If output isnt given, the formatted output is written to STDOUT. Several POD files can be processed in the same pod2man invocation (saving module load and compile times) by providing multiple pairs of input and output files on the command line.

--section, --release, --center, --date, and --official can be used to set the headers and footers to use; if not given, Pod::Man will assume various defaults.

pod2man assumes that your *roff formatters have a fixed-width font named CW. If yours is called something else (like CR), use --fixed to specify it. This generally only matters for troff output for printing. Similarly, you can set the fonts used for bold, italic, and bold italic fixed-width output.

Besides the obvious pod conversions, Pod::Man, and therefore pod2man also takes care of formatting func(), func(n), and simple variable references like $foo or @bar so you dont have to use code escapes for them; complex expressions like $fred{stuff} will still need to be escaped, though. It also translates dashes that arent used as hyphens into en dashes, makes long dashes--like this--into proper em dashes, fixes "paired quotes," and takes care of several other troff-specific tweaks. See Pod::Man for complete information.

OPTION

-c string, --center=string

Sets the centered page header to string. The default is "User Contributed Perl Documentation", but also see --official below.

-d string, --date=string

Set the left-hand footer string to this value. By default, the modification date of the input file will be used, or the current date if input comes from STDIN.

--fixed=font

The fixed-width font to use for vertabim text and code. Defaults to CW. Some systems may want CR instead. Only matters for troff(1) output.

--fixedbold=font

Bold version of the fixed-width font. Defaults to CB. Only matters for troff(1) output.

--fixeditalic=font

Italic version of the fixed-width font (actually, something of a misnomer, since most fixed-width fonts only have an oblique version, not an italic version). Defaults to CI. Only matters for troff(1) output.

--fixedbolditalic=font

Bold italic (probably actually oblique) version of the fixed-width font. Pod::Man doesnt assume you have this, and defaults to CB. Some systems (such as Solaris) have this font available as CX. Only matters for troff(1) output.

-h, --help

Print out usage information.

-l, --lax

Dont complain when required sections are missing. Not currently used, as POD checking functionality is not yet implemented in Pod::Man.

-o, --official

Set the default header to indicate that this page is part of the standard Perl release, if --center is not also given.

-q quotes, --quotes=quotes

Sets the quote marks used to surround C text to quotes. If quotes is a single character, it is used as both the left and right quote; if quotes is two characters, the first character is used as the left quote and the second as the right quoted; and if quotes is four characters, the first two are used as the left quote and the second two as the right quote.

quotes may also be set to the special value none, in which case no quote marks are added around C text (but the font is still changed for troff output).

-r, --release

Set the centered footer. By default, this is the version of Perl you run pod2man under. Note that some system an macro sets assume that the centered footer will be a modification date and will prepend something like "Last modified: "; if this is the case, you may want to set --release to the last modified date and --date to the version number.

-s, --section

Set the section for the .TH macro. The standard section numbering convention is to use 1 for user commands, 2 for system calls, 3 for functions, 4 for devices, 5 for file formats, 6 for games, 7 for miscellaneous information, and 8 for administrator commands. There is a lot of variation here, however; some systems (like Solaris) use 4 for file formats, 5 for miscellaneous information, and 7 for devices. Still others use 1m instead of 8, or some mix of both. About the only section numbers that are reliably consistent are 1, 2, and 3.
By default, section 1 will be used unless the file ends in .pm in which case section 3 will be selected.

EXAMPLES

pod2man program > program.1
pod2man SomeModule.pm /usr/perl/man/man3/SomeModule.3
pod2man --section=7 note.pod > note.7

If you would like to print out a lot of man page continuously, you probably want to set the C and D registers to set contiguous page numbering and even/odd paging, at least on some versions of man(7).

troff -man -rC1 -rD1 perl.1 perldata.1 perlsyn.1 ...

To get index entries on stderr, turn on the F register, as in:

troff -man -rF1 perl.1

The indexing merely outputs messages via .tm for each major page, section, subsection, item, and any X directives.

Apache2::xForwardedFor is a Perl module to re-set remote_ip to incoming clients ip when running mod_perl behind a reverse proxy server. In other words, copy the first IP from X-Forwarded-For header, which was set by your reverse proxy server, to the remote_ip connection property.

SYNOPSIS

in httpd.conf

PerlModule Apache2::xForwardedFor
PerlSetVar xForwardedForRequire 1
PerlSetVar xForwardedForAccept 192.168.1.1
PerlAddVar xForwardedForAccept 192.168.1.2
PerlPostReadRequestHandler Apache2::xForwardedFor

also note:
PerlSetVar xForwardedForRequireHeaderName X-Internal-Password
PerlSetVar xForwardedForRequireHeaderValue shibby

or:
PerlSetVar xForwardedForRequireHeaderName X-Forwarded-Server
PerlSetVar xForwardedForRequireHeaderValue lanServer1
PerlAddVar xForwardedForRequireHeaderValue lanServer2

USAGE

At this time you simply need to load the module and add it to the PerlPostReadRequestHandler phase of your mod_perl-enabled httpd, and set a few variables.

Apache2::xForwardedFor is really flexible and does some very odd ( but neat! ) things

Set some variables in httpd.conf, and thats it

This program is a daemon intended to catch someone installing a rootkit or running a packet sniffer. It is designed to run continually with a small footprint under an innocuous name. When triggered, it sends email, appends to a logfile, and disables networking or halts the system. it is designed to install with the minimum of disruption to a normal multiuser system, and should not require rebuilding with each kernel change or system upgrade.http://vancouver-webpages.com/rkdet/rkdet-0.54-2.i386.rpm
The program regularly verifies the checksum of a small number of system files that are typically modified by a rootkit. This list of files is compiled into the program. The file list, together with the system commands and messages, are obfuscated in the compiled code to prevent someone from figuring out what the program is for by eyeballing the binary.
The obfuscation algorithm is simple, but is compiled into the program and does not depend on external programs or other libraries.
The program takes a single optional numeric argument. If odd (bit 0 set), the interface "eth0" is checked for promiscuous operation (packet sniffing). If bit 1 is clear, the program will delete the default route on the network when triggered. Of bit 1 is set, the program will disable the eth0 interface. Systems with multiple interfaces may require an alternate interface specification in "xstrings.txt", or modification of the program to disable multiple interfaces. If bit 2 is set, the program will only log events and not disconnect the network.
The command may be modified to "init 1" or "shutdown -h now" if desired, or to run a script such as "panic.sh" (included).
Enhancements:
- Added configure script.
- Do not trap if checksum program fails (due to load, etc.)

Nikto is an Open Source web server scanner which performs comprehensive tests against web servers for multiple items, including over 3200 potentially dangerous CGIs/files, versions on over 625 servers, and version specific problems on over 230 servers. Scan items and plugins are frequently updated and can be automatically updated (if desired).
Nikto is not designed as an overly stealthy tool. It will test a web server in the shortest timespan possible, and its fairly obvious in log files. However, there is support for LibWhiskers anti-IDS methods in case you want to give it a try (or test your IDS system).
Not every check is a security problem, though most are. There are some items that are "info only" type checks that look for items that may not have a security flaw, but the webmaster or security engineer may not know are present on the server. These items are usually marked appropriately in the information printed. There are also some checks for unknown items which have been seen scanned for in log files.
Main features:
- Uses rfps LibWhisker as a base for all network funtionality
- Main scan database in CSV format for easy updates
- Determines "OK" vs "NOT FOUND" responses for each server, if possible
- Determines CGI directories for each server, if possible
- Switch HTTP versions as needed so that the server understands requests properly
- SSL Support (Unix with OpenSSL or maybe Windows with ActiveStates Perl/NetSSL)
- Output to file in plain text, HTML or CSV
- Generic and "server type" specific checks
- Plugin support (standard PERL)
- Checks for outdated server software
- Proxy support (with authentication)
- Host authentication (Basic)
- Watches for "bogus" OK responses
- Attempts to perform educated guesses for Authentication realms
- Captures/prints any Cookies received
- Mutate mode to "go fishing" on web servers for odd items
- Builds Mutate checks based on robots.txt entries (if present)
- Scan multiple ports on a target to find web servers (can integrate nmap for speed, if available)
- Multiple IDS evasion techniques
- Users can add a custom scan database
- Supports automatic code/check updates (with web access)
- Multiple host/port scanning (scan list files)
- Username guessing plugin via the cgiwrap program and Apache ~user methods
Enhancements:
- Added -config option to specify a config file (from Pavel Kankovsky)
- Added enhanced content checking to reduce false positives (from Pavel Kankovsky)
- Added more explicit licensing to code/databases

Devel::StealthDebug is a simple non-intrusive debug module.

SYNOPSIS

# in users code:
use Devel::StealthDebug;
... #!assert(< cond >)!
will die at this line if < cond > is not verified...
... #!watch(< var_name >)!
will carp each access to < var_name >
(Idea from Srinivasans monitor module)
... #!emit(< double_quoted_string_to_be_printed >)!
will emit the string Depending on emit_type
it will print, carp, croak or add to a file

carp is the default value for emit_type
... #!dump(< ref to a variable to be dumped >,< another ref >,...)!
will emit the variables structure
... #!when(< var_name >,< op >,< value >)!
will emit when < var_name > will pass the condition described by
< op >< value >. Currently, only works for watched scalar...
... #!emit_type(carp|croak|print)!
Define the emits behaviour

Can also be set on the use line :
use Devel::StealthDebug emit_type => croak;

Note that if you set it this way you gain an additional feature,
you can now emit to a file :

use Devel::StealthDebug emit_type => /path/to/file;
carp being the default value

You can also pass other optionq on the use line :

use Devel::StealthDebug ENABLE=>/path/to/file;
or
use Devel::StealthDebug ENABLE=>$ENV{WHATEVER};
or
use Devel::StealthDebug DUMPER=>1;

The third form will make the dump function use Data::Dumper.

The second form enable debugging only if the var passed as value is true (i.e. different from undef,,zero, or empty list)

The first form will enable the debug instructions if /path/to/file dont exist or exist AND contain a line (regex) which match the current file name.

This behaviour may sound odd, but as theres no way to know it you pass a value or a filename, a first test is made to check if the file exists, if it isnt the case then a value is assumed (so /path/to/missing/file is treated as a value which is true and so debugging is enabled). If the file exists, debugging is disabled unless this file contains a line whith a regex which matchs the current file name.

With Zhu3D you interactively can view and animate functions, isosurfaces and a further independent parametric system. Numerical solutions of an equation system can be found with a precise and reliable adaptive random search. The OpenGL-viewer supports zooming, scaling, rotating and translating as well as filed lightning or surface properties. Special effects are transparency, textures, fog and motion blur.
You have up to eight independent lights or spotlights, background settings, miscellaneous wire-modes or global illumination models. Pictures are rendered as PNG, JPG, PDF or PostScript and can be of arbitrary size. For textures Zhu3D recognizes nine common formats. Isosurfaces you can be visualized with different volume-based algorithms.
Zhu3D runs under Linux/Unix, Windows 98-XP and Mac OS X and is localized for English, German and Spanish. It supports different CPUs as well as different APIs like KDE, Motiv, Gnome or Windows. All settings can be changed dynamically at runtime. The application comes with extended help-files and a lot of examples.
COMPILING:
All you need is Qt 4.1 or later and support for OpenGL 1.2, what can be a software implementation like Mesa. The qmake easily can be taylored for special needs, what supports packagers.
HARDWARE:
For basic viewings even an old and slow PC without hardware accelerated OpenGL is sufficient. However, enabling goddies like animation, big textures and especially motion blur is a challenge for every GPU out there. On the other hand isosurfaces with dense meshes need a lot of CPU-power.
VERSIONS:
Whatever ends with an odd number, is considered as "pre". Those versions are not intended to be unfinished or buggy, but my testing capabilities are limited to my own HW/SW-configurations. So especially packagers may wait for an even number. This happens after a significant amount of downloads and no major problems reported. A complete Windows version is available - special thanks to Victor Fernandez, who is hosting this!
Enhancements:
- When wire-mode was on, the xyz-legends rendered incorrect. Fixed
- Small optimization in the "Special editor" ui-form for nicer view
- Slightly polishing startup file and some examples

Raster3D is a powerful set of tools for generating high quality raster images of proteins or other molecules.
The core program renders spheres, triangles, cylinders, and quadric surfaces with specular highlighting, Phong shading, and shadowing.
It uses an efficient software Z-buffer algorithm that is independent of any graphics hardware.
Main features:
- Raster3D uses a fast Z-buffer algorithm to produce high quality pixel images featuring one shadowing light source, additional non-shadowing light sources, specular highlighting, transparency, and Phong shaded surfaces. Output is in the form of a pixel image with 24 bits of color information per pixel plus one matte channel.
- Raster3D does not depend on graphics hardware. The rendering program currently supports output to files in AVS, JPEG, TIFF, PNG and SGI libimage format. To actually view or manipulate the images produced, you must also have installed an image viewing package (e.g. John Cristys ImageMagick or the SGI libimage utilities). The Raster3D rendering program can be integrated with ImageMagick to expand the flexibility of output formats and interactive use.
- Ancillary programs are provided for the generation of object descriptions based on atomic coordinates stored in PDB format. Although Raster3D is not intended as a general purpose ray-tracing package, nothing in the rendering process is specific to molecular graphics. Some of the algorithms used have been chosen for speed rather than generality, however. They work well for molecular graphics images, but possibly would produce odd results if used for very different types of image.
- Raster3D currently supports rendering six object types: spheres, triangles, planes, smooth-ended cylinders, round-ended cylinders, and quadric surfaces. It also supports the definition of material properties (transparency, bounding planes, color, reflectivity) that apply to groups of objects within the rendered scene.
Enhancements:
- changed the default output format to PNG for all programs
