Free web data extractor software for linux

Obscure-Extractor-GTK can extract data from simple and unusual archives as used by games, e.g. Neverwinter Nights, Homeworld 2, BloodRayne.

Mostly a framework where I can easily add new modules when I want to have a look at the inner workings of games, though the Delphi version has some more advanced stuff like support for old InstallShield archives that would need to be ported.

web-nsupdate is a web-based dynamic DNS update utility.

The web-nsupdate package provides a simple, web-based facility for clients to send dynamic DNS updates. Clients are typically DHCP hosts, such as a Linux system acting as a gateway for residential broadband service.

The client sends a simple web request (such as with the wget(1) or lynx(1) commands) to the web-nsupdate service to register their host request.

This package has been tested on a server with the following Debian packages:

* bind9 (ver 9.2.4-1)
* apache2 (ver 2.0.54-5)
* php4 (ver 4.3.10-16)

BE ADVISED: Its a pain in the butt to configure BIND to do dynamic DNS. You are going to need to do that to make "web-nsupdate" work. These instructions describe that process, so follow carefully. I *strongly* urge you to review the dnssec-keygen(8) and nsupdate(8) man pages first, so you can get some idea of what we are trying to accomplish.

Installation Instructions:

1. Copy the "web-nsupdate" files to a location such as
"/usr/local/lib/web-nsupdate". It is OK to install somewhere else,
just adjust the following directions accordingly.

2. Generate a TSIG key that "web-nsupdate" will use to authenticate
itself to the DNS server.

SECURE THIS KEY! Do not leave readable copies around. This key can
be used to make changes to DNS records managed by "web-nsupdate".

Here are the steps to generate the key:

cd /usr/local/lib/web-nsupdate
/usr/sbin/dnssec-keygen -a HMAC-MD5 -b 512 -n HOST web-nsupdate
chmod 440 Kweb-nsupdate*
# Below, adjust "www-data" to the GID your web server runs under.
chgrp www-data Kweb-nsupdate*

3. Setup the "web-nsupdate" definitions file, starting with the provided
sample. This file needs to be secured, to protect the client passwords
from being revealed.

cd /usr/local/lib/web-nsupdate
cp nsupdate-defs.php.sample nsupdate-defs.php
chmod 640 nsupdate-defs.php
# Below, adjust "www-data" to the GID your web server runs under.
chgrp www-data nsupdate-defs.php
vi nsupdate-defs.php

4. Verify that "nsupdate.php" has the correct path to the "nsupdate-defs.php"
file.

vi nsupdate.php
# Check the require_once() statement near the top.

5. Symlink the update script into your web site.

# Below, adjust "/var/www/nsupdate.php" to a location in your web server.
ln -s /usr/local/lib/web-nsupdate/nsupdate.php /var/www/nsupdate.php

At this point, the "web-nsupdate" front-end is configured. Now to
configure the nameserver back-end.

6. Assuming you dont already have a place for nameserver keys, create
a new file called "named.keys" that contains the TSIG key that
"web-nsupdate" will use. The file will look something like:

key web-nsupdate {
algorithm HMAC-MD5;
secret "jzzoMR4ocgZGq5pQho2Pr5r9DDHT4lWK8QO09cpvVtpvHqaUdzktBs1DHCslpPR8PwXU3ni8zjST/5FxEwg44Q==";
};

Replace the "secret" value show above with the key in the
"Kweb-nsupdate.+157+nnnnn.private" file you generated in step 2.

7. Install the "named.keys" file to the directory where your "named.conf"
resides. This file needs to be secured, to protect your namesever
from unauthorized updates.

If your "named.conf" directory is "/etc/bind", do:

# Below, adjust /etc/bind to directory where named.conf lives.
mv named.keys /etc/bind/named.keys
chmod 400 /etc/bind/named.keys
# Below, adjust "bind:bind" to the UID:GID your nameserver runs under.
chown bind:bind /etc/bind/named.keys

8. Add a line to your "named.conf" that says:

include "named.keys";

9. Modify your "named.conf" to list each host that web-nsupdate will
be updating. If, for example, you want to allow dynamic updates
from hosts "host1.example.com" and "host2.example.com", then modify
the "example.com" stanza in "named.conf" and add two lines:

zone "example.com" {
type master;
.
.
.
# add the lines below, one per host in thie zone
update-policy {
grant web-nsupdate. name host1.example.com. A;
grant web-nsupdate. name host2.example.com. A;
};
};

10. Test the update capability. Point your web browser to the installed
"nsupdate.php" script. This should bring up a form for manual
entry. Submit your entry, and verify the update was successful.

The Virtual Data Center (VDC) is a digital library system "in a box" for numeric data.

The VDC is a web application which provides everything necessary to maintain and disseminate collections of research studies: including facilities for the storage, archiving, cataloging, translation, and dissemination of each collection.

It includes on-line analysis, powered by the R Statistical environment. It also provides extensive support for distributed and federated collections including: location-independent naming of objects, distributed authentication and access control, federated metadata harvesting, remote repository caching, and distributed virtual

GData Java Client provides a library and source code that make it easy to access data through Google Data APIs.

The Google data APIs ("GData" for short) provide a simple standard protocol for reading and writing data on the web. GData combines common XML-based syndication formats (Atom and RSS) with a feed-publishing system based on the Atom publishing protocol, plus some extensions for handling queries.

Google also provides a set of client libraries for interacting with GData-enabled services, in a variety of programming languages. Using these libraries, you can construct GData requests, send them to a service, and receive responses.

Data::SimplePassword provides a simple random password generator.

SYNOPSIS

use Data::SimplePassword;

my $sp = Data::SimplePassword->new;
$sp->chars( 0..9, a..z, A..Z ); # optional

my $password = $sp->make_password( 8 ); # length

Its a very easy-to-use but a bit strong random password generator.
