Übersicht
Shareaza ist ein Mitte 2002 erstmals veröffentlichter Windows-Client
für das
Gnutella-Netzwerk mit einem leistungsstarken und funktionalem
Interface (siehe Screenshots) sowie einigen
speziellen Funktionen.
Beispielsweise kann Shareaza als erster Gnutella-Client auf
Bitzi-Metadaten
zugreifen (LimeWire hat
Bitzi-Support erst angekündigt) und verfügt über einen Metadaten-Editor.
Durch die Browser- und URL-Integration werden P2P-URIs wie "magnet:" und
"gnutella:" unterstützt:
magnet:?xt=urn:sha1:Y32Z6URUUYEY4AGRGGU5DDRCDQXXGVFW&dn=Shareaza1201.exe
gnutella://sha1:Y32Z6URUUYEY4AGRGGU5DDRCDQXXGVFW/Shareaza1201.exe/
Als Swarm Download wird der gleichzeitige Dateitransfer von
unterschiedlichen Quellen bezeichnet; dieses Feature bieten andere
Systeme wie der eDonkey 2000 oder
die FastTrack-Clients KaZaA und
Grokster bereits seit längerem.
Shareaza unterstützt auch neuere Funktionen des
Gnutella-Protokolls wie Ultrapeers, Query Routing, und GWebCache.
Lizenz: Freeware, Closed Source.
Anbieter: Shareaza Development Group.

Features
- A simple QuickStart wizard helps new users get up and running in
less than a minute.
- Swarmed downloads get what you want faster and more reliably.
Full support for multiple sources, automatic requerying, and pause
and resume across sessions.
- Powerful metadata support lets you search for content by artist,
album, bitrate, etc. Shareaza integrates varied metadata formats
from different clients into a simple unified display.
- Full library management features put you in charge of your
collection, with a nested folder browser, file-level sharing
control, hit and fetch statistics, metadata editor and automatic
change scanning.
- Automatic file hashing and metadata acquisition for common
music, image and application files provide the benefits of metadata
without the work. Operates in the background to keep your metabase
up to date. Shareaza automatically acquires metadata from asf, bmp,
exe, dll, gif, jpg, mp3, mpg, png, wma, and wmv files.
- Ultrapeer and query routing technology use intelligent
connections to save your bandwidth. With other Ultrapeer enabled
clients only. Shareaza gives you full control over your level of
Ultrapeer involvement.
- A kick-ass interface keeps you informed and gives you the power
to do what you want. Don't be restricted by dictated "tab-based"
interfaces. Shareaza lets you organise your session with multiple
windows and easy to use navigation. Right-click anywhere for an
intuitive popup command menu.
- Detailed diagnostic and monitoring capabilities including smart
packet dumping, search monitoring and filtered hit monitoring enable
you to keep an eye on the network.
- Fully featured and infinitely configurable performance graphing
visualises key indicators such as bandwidth utilisation, neighbour
interactions, downloads, uploads and network characteristics over
time. Create multiple graphs to keep track of performance (or just
to look cool).
- Chat peer-to-peer with other Shareaza or LimeWire users. You can
initiate a converation from a search result, a download or an
upload.
- Support for the latest Gnutella protocol enhancements such as
v0.6 handshaking, Ultrapeer/Supernode, QRP, BYE, pong caching, flow
control, EQHD, HUGE, HTTP/1.1, chat and XML metadata ensure you're
PC is a good citizen on the network.
- Extensive options put power users in total control of the
software, from high-level settings to low-level communications
parameters, buffer sizes, caching and routing policies.
- Shareaza's lean and mean design doesn't chew up half your
available memory and CPU time, or take ages to load. And it doesn't
crash your PC if you leave it running for too long. Multithreaded
native code ensures smooth operating conditions without going
overboard and taxing resources.
- Much better UltraPeer address storage and selection in the host
cache. This seriously drops connection time by a factor of 3 or more
once it's had time to accumulate some entries. It also helps other
clients get connected better. It worked alright before, it works
even better now.
- Full 100% support for the latest HUGE specification. Previously
Shareaza supported 90% of it, with hashing, secure fragment
downloading by hash, grouping and requesting by hash, etc -- the
important bits.
- Now however the final 10% is supported – download source meshes.
This has the potential to really improve downloads for everyone once
more clients adopt it. Shareaza helps to build a mesh of alternate
locations for each file by receiving and transmitting alternate
sources on every upload and download transaction it performs, and
maintaining a database of potential sources for each library and "in
progress" file.
- Ability to access and download Bitzi metadata. You can now query
the Bitzi.com online file information database for information about
files in your library or the Gnutella network. As far as I’m aware
this isn’t available in any other clients yet – very cool. (see
www.bitzi.com for more
information)
- Select a single file and open the Bitzi web "ticket", which
shows information about the selected file in your browser. Or use
the innovative Acquire Metadata feature to download metadata
directly from Bitzi.com to your local library database. Shareaza
automatically converts data formats and merges foreign information
with any existing annotations. This information is then stored in
your library and can be used by you and other Gnutella users for
richer, more powerful searches.
- Comprehensive security system. The new Security Manager window
allows you to create simple or complex access control rules that
govern incoming, outgoing and routed traffic. Deny connections from
hostile hosts or networks, or create a private network of servents
by listing the network ranges to accept and denying the rest. Each
rule has individual hit counting and automatic expiry control. The
security manager provides more power than you’ll find anywhere else,
but it’s also very simple to use with easy point-and-click Ban Host
options in the Uploads and Search windows.
- Enhanced library management tools. The Library window has
undergone some major additions, and now offers a whole lot more than
it did before. You can now copy, move and delete files within your
library, right from within Shareaza. This has the advantage of
coordinating with the file sharing core, and it also operates
transparently on any metadata you have stored. There’s also commands
like Enqueue to add selected files to an external media playlist,
and Refresh to update statistics. You can also see file hashing
progress (unhashed files appear gray), and shared/unshared folders
are more clearly indicated.
- The ability to directly download URLs, and manually add sources
to existing downloads. You can now leverage Shareaza's fragmenting
download engine (which from what I've seen is more advanced than
that found in any other P2P product) to download any URL,
Gnutella-based or not. HTTP download URLs can be entered on the
Tools menu. You can also add sources to existing downloads by
right-clicking, and entering a URL.
- The uploads window has been redesigned for more intuitive
control. Uploads are now displayed by file rather than by host, and
shown in green when active and in black when disconnected. You can
still view the enhanced view by selecting “Group by Host”.
- More statistics - Shareaza displays the total unique files and
total hits in search windows, and displays a readout of bandwidth
and transfer usage on the status bar. This stuff is not new (there’s
lots of reporting functionality in the performance graphing system
already), but now it’s visible all the time. You can also see the
number of active download transfers, sources per file, requests per
upload, etc.
- Ability to search by raw SHA1. Simply type the file’s URN, ala
"urn:sha1:xxxxx" into the search window to search for an exact file
by hash.
- Better Search, Monitor and Packet Dump performance. Some people
noted poor visual performance in these windows, which has been
corrected. These areas now utilise batched updates to prevent CPU
use from getting out of hand.
- Better upload limiting. Shareaza always supported limiting the
number of total uploads and the number per unique host, which
provided good protection. However some clients can be very
aggressive and send frequent requests without closing their old
connections. Shareaza now has additional measures to limit not only
the number of active transfers per host, but also throttle the
number of raw connections.
