Wireshark is the world’s foremost network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It is the de facto (and often de jure) standard across many industries and educational institutions.

Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

Features

Wireshark has a rich feature set which includes the following:

• Deep inspection of hundreds of protocols, with more being added all the time
• Live capture and offline analysis
• Standard three-pane packet browser
• Multi-platform: Runs on Windows, Linux, OS X, Solaris, FreeBSD, NetBSD, and many others
• Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
• The most powerful display filters in the industry
• Rich VoIP analysis
• Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
• Capture files compressed with gzip can be decompressed on the fly
• Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
• Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
• Coloring rules can be applied to the packet list for quick, intuitive analysis
• Output can be exported to XML, PostScript®, CSV, or plain text

MLDonkey is a multi-platform and freely distributed eDonkey client, a P2P (Peer-to-Peer) file-sharing application. It provides users with both a server (daemon) and graphical user interface (GUI).

It seems to be the first ever open source application that could access the eDonkey peer-to-peer file sharing network, as a eDonkey2000 clone. It officially supports the Linux, BSD, Solaris, Mac OS X, MorphOS, and Microsoft Windows operating systems.

Currently, the application supports several large P2P networks, including Overnet, BitTorrent, Fasttrack (Kazaa, Imesh, Grobster), Gnutella (Bearshare, Limewire, etc), Gnutella2 (Shareaza), Soulseek, Opennap, and Direct-Connect (DC++).

Several user interfaces are available for this project, including web-based, native GUIs, Telnet based and basic Wap front-ends. The most simple and effective appears to be the Telnet interface accessible through the command-line (telnet 127.0.0.1 4000) or via the Putty application.

While the Wap interface is extremely simple and provides users only with very basic functionality, such as current download and upload speed, current running downloads, as well as pause, resume, and cancel functions, the web-based interface can be easily accessed with any modern web browser through http://admin@127.0.0.1:4080.

MLdonkey comes by default with a GTK interface. However, there are many open source or commercial GUI (Graphical User Interfaces) front-ends available, including Sancho, KMLdonkey, G2Gui, CocoDonkey, xDonkey, mlMac, Nulu GUI ML, MLdonkeyWatch, phpEselGui, saman, Platero, Alemula, Zuul, JMoule, Web-GMUI, and Rmldonkey.

All the aforementioned MLdonkey interfaces can be used both remotely and locally. Furthermore, it allows users to easily enable or disable P2P networks, perform parallel searches on all enabled peer-to-peer networks, as well as to download files concurrently from multiple clients.

Summing up, MLdonkey is a very powerful and popular P2P client that runs on most operating systems, supports a wide range of peer-to-peer networks, and comes with a plethora of user interfaces.
