Class::InsideOut is a Perl module with a safe, simple inside-out object construction kit.
SYNOPSIS
package My::Class;
use Class::InsideOut qw( public private register id );
public name => my %name; # accessor: name()
private age => my %age; # no accessor
sub new { register( shift ) }
sub greeting {
my $self = shift;
return "Hello, my name is $name{ id $self }";
}
This is a simple, safe and streamlined toolkit for building inside-out objects. Unlike most other inside-out object building modules already on CPAN, this module aims for minimalism and robustness:
- Does not require derived classes to subclass it
- Uses no source filters, attributes or CHECK blocks
- Supports any underlying object type including black-box inheritance
- Does not leak memory on object destruction
- Overloading-safe
- Thread-safe for Perl 5.8 or better
- mod_perl compatible
- Makes no assumption about inheritance or initializer needs
It provides the minimal support necessary for creating safe inside-out objects and generating flexible accessors.

mod_coredumper uses the CoreDumper library from Google to fetch a GDB compatible core file from Apache, over HTTP.

Warning: Do not enable mod_coredumper on a public server without access control in place!

This module allows a remote user to possibly download passwords or other sensitive information stored inside Apache.

Run a web server inside LAN is a simple script to run a WWW server inside a Local Area Network. Run a web server inside LAN script assume all iptables features are compiled statically in the kernel, or all modules are loaded.

Otherwise you may encounter some surprises trying to utilize the more featureful and creative commandlines that Ive come up with.

Sample:

#external and internal interfaces
EXT=eth0
INT=eth1

# clear everything, and create my cascading chains
iptables -F
iptables -N e0
iptables -N tcpin
iptables -N udpin

# e0 is the name of our chain for eth0
iptables -I INPUT -i $EXT -j e0

# OUTPUT Chain
iptables -A OUTPUT -o $EXT -j DROP -p icmp --icmp-type ! echo-request

# remote gnutella queries were really pissing me off one day
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --dport 6346
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --sport 6346

# $EXT Chain
# a single rule to accept SYN Packets for multiple ports (up to 15)
iptables -A tcpin -j ACCEPT -p tcp --syn -m multiport --destination-ports 873,993,995,143,80,113,21,22,23,25,53

# stateful connection tracking is wonderful stuff
# ESTABLISHED tcp connections are let through
# If we send a SYN out, the ACK is seen as RELATED
# then further communication is accepted by the ESTABLISHED rule
iptables -A e0 -j ACCEPT -m state --state ESTABLISHED
iptables -A e0 -j ACCEPT -m state --state RELATED

# certain ports I simply DROP
iptables -A tcpin -j DROP -p tcp --syn -m multiport --destination-ports 6346,139

# UDP rules...
iptables -A udpin -j DROP -p udp -m multiport --destination-ports 137,27960

# I run a DNS server, so we must accept UDP packets on port 53
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 53

# lets log NEW udp packets on ports 1024:65535, then let them through
iptables -A udpin -j LOG -p udp -m state --state NEW --destination-port 1024:65535 --log-level debug --log-prefix UDPNEW --log-ip-options
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 1024:65535

# lets log NEW tcp packets on ports 1024:65535, then let them through

iptables -A tcpin -j ACCEPT -p tcp --syn --destination-port 1024:65535

# lets log INVALID or NEW tcp packets on priveleged ports, then DROP
# (remember I have certain ACCEPT rules higher up the chain)
iptables -A tcpin -j LOG -p tcp -m state --state INVALID,NEW --destination-port 1:1023 --log-level warn --log-prefix TCPPRIV --log-tcp-options --log-ip-options

RJBs Digital Media Center is a music player.
RJBs Digital Music Center is designed to run on dedicated hardware. Because of this. It running as root. Very dangerous. Other than grabbing the X display and calling stop and halt scripts. It should be able to run as a non-root user. I will look into this on future releases.
Install steps:
(1) Install Nvidia Graphics Card.
(2) Plug X10 or IRMan control module into Com1.
(3) Connect Computer to Television
(4) Install RedHat 9.0
(5) During RedHat install select "Server Install"
(5) During package selection
(a) Select The Following Packages
X Window System
Sound and Video
Windows File Server
Development Tools
X Software Development
(b) De-Select The Following Packages
Printing Support
Text Based internet
Server Configuration Tools
Web Server
Administration Tools
(6) Identify or Create a directory for your Media files.
mkdir /usr/local/Media
Would be a good choice. The install script will ask and expect this path to exist. It will create a symbolic link to it. Also create symbolic link inside to for Cdrom to /mnt/cdrom
(7) As root UnZip/Tar the DMC release in /usr/local
cd /usr/local
tar zxvf dmc-releaseV2.0.tgz.tgz
(8) If your System is a HP DEC then you need to copy from the original HP disk the binary decvfdcmd.
cp /opt/odin/dec/bin/decvfdcmd /tmp
This binary controls the front LCD display.
The install script will ask for this path.
(9) As root run the DMC Install Script.
cd /usr/local/dmc/bin
./Install.sh
(10) Answer questions and follow instructions
(11) Good Luck!

Class::InsideOut::Manual::About is a guide to this and other implementations of the inside-out technique.
This manual provides an overview of the inside-out technique and its application within Class::InsideOut and other modules. It also provides a list of references for further study.
Inside-out object basics
Inside-out objects use the blessed reference as an index into lexical data structures holding object properties, rather than using the blessed reference itself as a data structure.
$self->{ name } = "Larry"; # classic, hash-based object
$name{ refaddr $self } = "Larry"; # inside-out
The inside-out approach offers three major benefits:
- Enforced encapsulation: object properties cannot be accessed directly from ouside the lexical scope that declared them
- Making the property name part of a lexical variable rather than a hash-key means that typos in the name will be caught as compile-time errors (if using strict)
- If the memory address of the blessed reference is used as the index, the reference can be of any type
In exchange for these benefits, robust implementation of inside-out objects can be quite complex. Class::InsideOut manages that complexity.
Philosophy of Class::InsideOut
Class::InsideOut provides a set of tools for building safe inside-out classes with maximum flexibility.
It aims to offer minimal restrictions beyond those necessary for robustness of the inside-out technique. All capabilities necessary for robustness should be automatic. Anything that can be optional should be. The design should not introduce new restrictions unrelated to inside-out objects, such as attributes and CHECK blocks that cause problems for mod_perl or the use of source filters for syntatic sugar.
As a result, only a few things are mandatory:
- Properties must be based on hashes and declared via property
- Property hashes must be keyed on the Scalar::Util::refaddr
- register must be called on all new objects
All other implementation details, including constructors, initializers and class inheritance management are left to the user (though a very simple constructor is available as a convenience). This does requires some additional work, but maximizes freedom. Class::InsideOut is intended to be a base class providing only fundamental features. Subclasses of Class::InsideOut could be written that build upon it to provide particular styles of constructor, destructor and inheritance support.

INSERT (the Inside Security Rescue Toolkit) aims to be a multi-functional, multi-purpose disaster recovery and network analysis system. It boots from a credit card-sized CD-ROM and is basically a stripped-down version of Knoppix. It features good hardware detection, fluxbox, emelfm, links-hacked, ssh, tcpdump, nmap, chntpwd, and much more.
INSERT provides full read-write support for NTFS partitions (using captive), and the ClamAV virus scanner (including a fairly recent signature database and a GUI). It also has a network boot facility.
Main features:
- full read-write support for NTFS-partitions using captive
- support for various file system types: EXT2,EXT3,MINIX,REISERFS,JFS,XFS,NTFS,FAT,MSDOS,NFS,SMBFS,NCPFS,UDF,UFS,HFS,HFS+
- support for linux software RAID and LVM
- support for WLAN adapters
- network analysis (e.g. nmap, tcpdump)
- disaster recovery (e.g. parted, gpart, partimage, testdisk, recover)
- virus scanning (Clam Antivirus)
- computer forensics (e.g. chkrootkit, rootkit hunter)
- surf the internet (e.g. links-hacked, AxY FTP)
- network boot server to boot network boot enabled clients that cannot boot from the CD
- based on Linux kernel 2.4.27 and Knoppix 3.6
