Gcover is a cd cover editor program for the Gnome community. Its my first development under Linux/C/Gnome so dont take it too hard. There are two reasons why I release this program:
I think it is quite useful If you want to create nice covers for your "home made" cds (eg.:audio cds from mp3s or data cds).
I couldnt find any good cover editor program for Gnome.
Main features:
- Different kind of covers (One or two back pages,booklet for your front pages or simple 2 paged front)
- Title text,page text with different fonts and colors. Many text formatting opportunities(eg.:margins,alignment,columns,word warp,etc..)
- Picture for every pages with scaling options,border cutting,different interpolation modes(using the power of gdk-pixbuf),etc..
- Printing to postscript output,real printers. Print preview.
- Plain text loading to the page editor or to the internal clipboard
- And so on... Its better if you look the program

FlatGallery is a simple image gallery producer that requires no database backend. Users simply add images to a directory and FlatGallery will recognise this and produce thumbnails that are cached for later use.
Producing thumbnails only when images ar added lessens the strain on servers that produce thumbnails "on the fly" for every image, every time the page is refreshed. FlatGallery also deletes thumbnails when the image is removed from the image directory. Nearly all aspects of FlatGallery are customizable such as number of images per page, thumbnail size, what to display, etc.
It can be run as a standalone gallery or as an integrated part of a pre-existing webpage. The class structure of FlatGallery makes it extremely small and flexible. All your formating is done via stylesheets. There is little to no set-up required. All you need are PHP, GDLib, and some pictures!
Enhancements:
- Minor: Fixed integration issue with other PHP
- Minor: die() functions replaced by return false;
- Minor: Errors return false and set $gal->error; to an error message
- Minor: Image directory only needs to be readable now. Chmod 0755 is sufficient.

File::Mirror is a Perl extension for recursive directory copy.

SYNOPSIS

use File::Mirror;

# recurvie copy /path/A to /path/B

mirror /path/A, /path/B;

# or do things you like

recursive { my ($from, $to) = @_; copy($from, $to) } /path/A, /path/B;

File::Mirror provides two helper functions to do recursive directory operations between source path and destination path. One is to call mirror which will do recursive copy. The other is to call recursive with a code block, which will be code for every file found in the source path.

File::Mirror fills the gap between File::Copy::Recursive, which only focuses on file copying, and File::Find, which is too obstacal to use.

phpsniffer shows that PHP really is the right tool for every programmnig task imaginable (humor, laugh), I submit for your amusement, phpsniffer.

phpsniffer is a packet sniffer written entirely in PHP without any PECL/PEAR extensions. (It is recommended that you check out Phpcap for any serious sniffing at http://alcane.newffr.com/phpcap/).

phpsniffer has some limitations:

- You probably will only see one side of a conversation.
- You might miss packets with a short TTL.
- Currently only IP,ICMP,UDP, and TCP headers are decoded.
- Sockets must be enable in your PHP build.

Script for a multi-homed firewall is an example IPTables 1.2.1 script for a dual-homed firewall.

This script has not yet been tested thoroughly on a dual-homed firewall. If you find any problems, please drop me an email.

Current versions and documentation are available at http://www.sentry.net/~obsid/IPTables/rc.scripts.dir/current/

## User-defined Chains ##

Chain KEEP_STATE
The KEEP_STATE chain holds a few rules for generic stateful packet filtering.
This chain is called from many of the INPUT/OUTPUT chains to DROP "INVALID"
and perhaps "UNCLEAN" packets and allow other packets from "RELATED" or
"ESTABLISHED" connections.

CHECK_FLAGS
The CHECK_FLAGS chain contains a few rules to filter based on TCP flags.
These rules do indeed filter mainly bogus/malicious traffic(scans, etc). It
would be a good idea to keep an eye on what these rules send to the logs.
Null scans are also logged and dropped, in the mangle table.

DENY_PORTS
The DENY_PORTS chains contains a few rules to DROP and/or LOG packets based
on the source and/or destination port number of the packet.

Packets destined to/from the following ports are dropped by default in the script. These are just some examples of some commonly used ports that certain daemons/trojans/DDoS agents may utilize.

## TCP ##
137:139 SMB
2049 NFS
6000:6063 X
20034 Netbus 2 Pro
12345:12346 Netbus
27374 SubSeven
27665,27444,31335 Trinoo
10498,12754 Mstream

## UDP ##
2049 NFS
31337 BO2k
27444,31335 Trinoo
10498 mstream

These are just examples to stare at. They guarantee no real protection against the associated trojans.

For more common port numbers check out:
http://www.sans.org/newlook/resources/IDFAQ/oddports.htm

ALLOW_PORTS
The ALLOW_PORTS chain simply ACCEPTs packets based on port number. If you have
a default FORWARD policy of DROP, then you would need to utilize a chain like
this if you are DNATing/routing connections behind the firewall or perhaps
running services on(!!!) the firewall.

ALLOW_ICMP
The ALLOW_ICMP chains simply allows packets based on ICMP type. Currently
the firewall allows the flow of the following ICMP types:
Echo Reply (pong)
Destination Unreachable
Echo Request (ping)
TTL Exceeded (traceroute)

SRC_EGRESS && DST_EGRESS
The SRC_EGRESS and DST_EGRESS chains filter packets that have a source or
destination IP address matching an array of private or reserved subnets.

TOS_OUTPUT
The TOS_OUTPUT chain exists in the mangle table and mangles the TOS(Type
of Service) field in the IP header of locally generated, outgoing packets.

TOS_PREROUTING
The TOS_PREROUTING chain exists in the mangle table and mangles the TOS(Type
of Service) field in the IP header of packets being routed through the firewall.

The following user-defined chains are pretty obvious. The firewall script is designed to have a user-defined INPUT and OUTPUT chain for every available interface. From these user-defined chains are called the user-defined chains
mentioned above, which I call "Special Chains". The chains below are then called by the built-in INPUT/OUTPUT/FORWARD chains. This isnt really the rule, of course, alot of the user-defined chains mentioned above are called directly from the built-in INPUT/OUTPUT/FORWARD chains. This is done to assure proper flow of the packets through the filters.

EXTERNAL_INPUT
INTERNAL_INPUT
DMZ_INPUT
LO_INPUT
EXTERNAL_OUTPUT
INTERNAL_OUTPUT
DMZ_OUTPUT
LO_OUTPUT

xRecurseDiff is a small sotware, useful for all those programmers working with a own code repository (class library or similar). Helps to rapidly verify difference between different copies of the same file.

For every file in project directory search in library directory for files having the same name. A report containing results is shown. A detailed diff output can be shown. Search can be case-insensitive and limited by a char filter.

Installation:

Extract archive: tar xzf xRecurseDiff.version.tgz
Enter in the new directory: cd xRecurseDiff.version
Link the correct language file: ln -s lang/xrdstrings-lang.h xrdstrings.h
Compile: make
Copy in the path: cp xrecursediff /usr/local/bin/

Isaac Newton Organizer is a software that helps you organise your plans and work, and keep track of your progress. Isaac Newton Organizer allows you to add tasks for any date in a visually appealing interface, and helps you mark these tasks according to their status.

It also allows you to add "recurrent tasks" which are tasks that have a frequency associated with them. For example, you could add tasks representing your loved ones birthday, and make it recurrent for every year, so that you never forget the birthday any longer!

There are hosts of other features in Isaac Newton Organizer, so please look at the Features section to find out more.
