For you web developers... Ever wanted to run your own chat room from your site? Well, now you can, as many as you like, on as many pages of your site as you like! This really is a truly dynamic chat plugin for your website! Oh yes, and it's free of course...
So click here to check out the new GutterStar.net Dynamic Live Chat Plugin!
To find additional resources, enter the search terms: "direct connect hubs" or "dc++"
Introduction
DC++ is an amazing Windows program for accessing the Direct Connect Network, which is one of the most extensive underground file sharing networks on the web! How awesome is that?!
This download is actually the same as is available from the DC++ home page, http://dcplusplus.sourceforge.net/. However, I've included this download here as well, to ensure that there are no version conflicts between the JAWS scripts for DC++ and the DC++ application itself.
Rather than go through all of the totally awesome features that DC++ actually has (like realtime chat, instant messaging, remote p2p file and folder browsing, etc.), simply visit http://dcplusplus.sourceforge.net/ to read all about DC++ and its various features!
Getting Started, It's Easy...
Getting up and running is very simple using DC++... Just follow these steps to get going...
2. After starting DC++, configure your connection by opening the File menu, selecting Settings, then open the Connection tab.
a. If you connect directly to the internet, choose Direct Connection for inbound.
b. If you connect to the internet using a router, choose UPnP or UDP for inbound.
Once done, click OK.
3. Open the Public Hubs tab from the View menu. You should now see a bunch of available hubs.
4. Within the Filter edit field, type something that relates to the types of files or information that you are interested in. Examples: "books", "comics", etc. Press return to activate the filter, then tab to the results again. The list should have narrowed dramatically.
5. Right-click one of the hubs, and choose Connect. Pay special attention to any instructions that are displayed within the Main Chat window, or the Private Message window, since this is often where special hub related rules and instructions will be sent for you to read.
6. Once you are connected, you should now find more hubs... Press Control+S to open the Search window, type "hubs" in the search field, ensure that "Any" is selected within the file type field, and click Search.
7. You should be getting many results such as folders and files with names like hubs.txt, or Hubs Database, etc. Just right-click one of these, and choose Download to get lists for more hubs that may be of interest. This is very useful for finding private hubs that are not listed publically. You can then manually add a hub address within the Favorite Hubs window, by clicking New.
Important: When you click the option to browse another user's file list, don't be surprised if it takes a while. When you click this option (by right-clicking a user's name, and choosing this option), the file list is automatically generated on the user's computer, then the file list is added to your download queue. When the file list completes downloading, then it will appear. You can check the progress of this by opening the Download Queue window, or by viewing the Current Transfers window.
File sharing usually follows the
peer-to-peer
(P2P) model, where the files are stored on and served by personal computers of the users. Most people who engage in file sharing on the Internet both provide
(upload) files and receive files (download).
P2P file sharing is distinct from file trading in that downloading files from a P2P network does not require uploading, although some networks either provide
incentives for uploading such as credits or forcing the sharing of files being currently downloaded. Napster started this whole wave and has since became
a legal spot for downloads with a fee schedule.
The first generation of peer-to-peer file sharing networks had a centralized file list. In the centralized peer-to-peer model, a user would send a search
to the centralized server of what they were looking for. The server then sends back a list of peers that have the data and facilitates the connection and
download.
The first file-sharing programs marked themselves by inquiries to a server, either the data to the download held ready or in appropriate different
Peers
and so-called
Nodes
further-obtained, so that one could download there. Two examples were
Napster
(today using a pay system) and
eDonkey2000
in the server version (today likewise with
Overnet
and
KAD
- network decentralized).
Webhosting
is also used for file sharing, since it makes it possible to exchange privately. In small communities popular files can be distributed very quickly and
efficiently. Web hosters are independent of each other; therefore contents are not distributed further. Other terms for this are one-click hosting and
web-based sharing.
File Sharing On The Social Graph
Recently,
Facebook
opened up its
API
to 3rd party developers that has allowed for a new type of file-sharing service to emerge. Box.net and FreeDrive.com
[3]
are two examples of companies that have specific Facebook Applications that allow file sharing to be easily accomplished between friends.

Second P2P-Generation: Decentralization
After Napster encountered legal troubles,
Justin Frankel
of Nullsoft set out to create a network without a central index server, and Gnutella was the result. Unfortunately, the Gnutella model of all nodes being
equal quickly died from bottlenecks as the network grew from incoming Napster refugees.
FastTrack
solved this problem by having some nodes be 'more equal than others'.
By electing some higher-capacity nodes to be indexing nodes, with lower capacity nodes branching off from them, FastTrack allowed for a network that could
scale to a much larger size. Gnutella quickly adopted this model, and most current peer-to-peer networks implement this design, as it allows for large
and efficient networks without central servers.
Also included in the second generation are
distributed hash tables
(DHTs), which help solve the scalability problem by electing various nodes to index certain hashes (which are used to identify files), allowing for fast
and efficient searching for any instances of a file on the network. This is not without drawbacks; perhaps most significantly, DHTs do not directly support
keyword searching (as opposed to exact-match searching).
The best examples are
Gnutella,
Kazaa
or
eMule
with
Kademlia
, whereby Kazaa has still a central server for logging in.
eDonkey2000/
Overnet
, Gnutella,
FastTrack
and
Ares Galaxy
have summed up approx. 10.3 million users (as of April 2006, according to slyck.com). This number does not necessarily correspond to the actual number
of persons who use these networks; it must be assumed that some use multiple clients for different networks.
