MLDonkey is an open-source, multi-protocol, peer-to-peer file sharing application that runs as a back-end server application on many platforms. It can be controlled through a user interface provided by one of many separate front-ends, including a Web interface, telnet interface and over a dozen native client programs.

Originally a Linux client for the eDonkey protocol, it now runs on many flavors of Unix-like, OS X, Microsoft Windows and MorphOS and supports numerous peer-to-peer protocols.

It is written in OCaml, with some C and some assembly.

History

[edit]

Development of the software began in late 2001. The original developer of MLDonkey is Fabrice Le Fessant from INRIA. It was originally conceived as an effort to spread the use of OCaml in the open source community.[2]

In January 2003, Slyck.com reported brief friction between MLDonkey developers and the official Overnet MetaMachine developers, which denounced MLDonkey as a "rogue client", allegedly for incorrect behavior on the network.[3]

Versions before 3.0 have a known security vulnerability that allows an attacker with access to the web interface to read any file on the file system.[4]

Features

[edit]

Features of MLdonkey core:

Written in the OCaml programming language and licensed under the GPL-2.0-or-later license, the application separates the user interface (which can be a web browser, telnet, or a third-party GUI application) and the code that interacts with the peer-to-peer networks.

MLDonkey is able to connect simultaneously to different peers using different network protocols. In addition it can download and merge parts of one file from different network protocols[5] although this feature is currently documented as experimental. MLDonkey runs in a terminal session and does not require a GUI environment, saving memory and processing resources. Behavior is controlled by editable configuration files, or—in a more user friendly fashion—from a separate user interface.

From release 2.9.0 (2007) on, support for gnutella and G2 are no longer compiled in by default as both plugins are buggy and currently unmaintained;[6] however, it is still possible to compile them in by making the appropriate setting in the configuration file.[7]

View on Grokipedia
from Grokipedia
MLDonkey is an open-source, multi-protocol file-sharing daemon written primarily in , designed to operate as a lightweight backend server across platforms including , Unix variants, Windows, and macOS, without an integrated . Initiated in late 2001 by developer Fabrice Le Fessant at INRIA as a Unix- and -focused clone of the proprietary client—which had limited support for those environments—it rapidly expanded to encompass multiple networks such as eDonkey (including Overnet and variants), (with DHT support), Direct Connect, and even HTTP/FTP sources. This versatility marked MLDonkey as the inaugural open-source client for the , enabling decentralized file exchanges on a scale previously dominated by closed-source tools, while its daemon facilitates headless operation on low-resource devices via remote interfaces like web browsers, telnet, or third-party GUIs. Among its defining characteristics is the emphasis on and , with the core process handling downloads in the background to minimize system overhead, though early features like simultaneous multi-server connections—intended to accelerate transfers—drew criticism for potentially straining network infrastructure. Ongoing maintenance, including ports and forks addressing compatibility with modern OCaml versions (4.03 to under 5.0), sustains its relevance for users prioritizing cross-network interoperability over user-friendly frontends.

History

Origins and Initial Development

MLDonkey originated as an open-source peer-to-peer file-sharing client developed by Fabrice Le Fessant, a researcher at the French National Institute for Research in Digital Science and Technology (INRIA), who initiated its creation in 2002. Le Fessant, along with contributor Simon Patarin, implemented the software in Objective Caml (OCaml) to leverage the language's efficiency and cross-platform capabilities, enabling it to run on Unix-like systems where proprietary eDonkey clients were inadequately supported. The project addressed a gap in the eDonkey network by providing the first publicly available client with reverse-engineered protocol compatibility, achieved through tools such as Pandora for dissecting the closed-source eDonkey2000 implementation. The software's initial design emphasized a server-like daemon , allowing continuous operation independent of graphical interfaces and controllable via command-line, , or web-based frontends, which facilitated resource-efficient sharing on non-Windows platforms. Registered on the Savannah /NonGNU software forge on February 19, 2002, MLDonkey began as a dedicated eDonkey clone before evolving into a multi-protocol tool, reflecting Le Fessant's focus on distributed systems and technologies during his INRIA tenure. This foundational approach prioritized backend stability and protocol fidelity over user-facing simplicity, setting it apart from contemporaneous GUI-driven alternatives.

Major Releases and Protocol Expansions

MLDonkey's inaugural release in 2001 focused exclusively on the , serving as an open-source Unix/ client for a protocol then dominated by closed-source software. Early expansions integrated the Overnet protocol, a decentralized variant using the same file-transfer mechanisms as eDonkey but with distributed hashing for peer discovery, enabling compatibility shortly after Overnet's emergence around 2002-2003. BitTorrent support arrived with version 2.5.22 in July 2004, allowing MLDonkey to function as a console client for the protocol and introducing multi-network swarming capabilities that permitted hybrid downloads across eDonkey/Overnet and BitTorrent sources. By version 2.5.30 and later in the 2.x series, additional protocols such as Gnutella, Gnutella2, Fasttrack, and Kademlia (for eMule compatibility) were incorporated, establishing MLDonkey as a versatile multi-protocol daemon. The 3.x series, commencing with version 3.0.6 in November 2010, emphasized refinements over entirely new protocols, including for and eMule-specific features like handling. Version 3.1.0, released August 10, 2011, added (DHT) functionality to enhance 's decentralized tracking. Subsequent updates like 3.1.3 on August 28, 2012, extended with link parsing for metadata-less torrent initiation. Later releases, including 3.1.5 in March 2014, 3.1.6 in January 2017, and 3.2.0 in August 2024, prioritized bug fixes, security patches (e.g., resolutions), and compatibility with evolving dependencies like 4.14 and miniupnpc 2.2.8, without introducing novel protocols. These updates maintained core multi-protocol interoperability amid declining active development on certain legacy networks.

Decline in Official Development and Community Maintenance

The official development of MLDonkey, primarily coordinated through the Savannah hosting site, effectively stalled after the release of version 3.1.5 on March 22, 2014, with no subsequent major updates or news announcements from the core team. This period marked a transition from active feature expansions in earlier versions to minimal maintenance, as evidenced by the absence of commits or releases in the original repositories beyond sporadic patches for existing codebases. The project's mailing lists, once used for development discussions, saw their last notable activity around 2005, further indicating a long-term lull in coordinated efforts. Community-driven maintenance emerged as a response, with forks such as the ygrek repository on taking over compatibility fixes and builds. This released version 3.2.1 on August 19, 2024, focusing on support for versions 4.03 to 4.14 to address compilation issues on modern systems, rather than introducing new protocols or features. Other community initiatives, including Docker containers and updated frontends like mldonkey-next, have sustained usability for niche users, but these efforts remain fragmented and reactive, often prioritizing installation hurdles over innovation. The original documentation and user forums, hosted at mldonkey.sourceforge.net, were shut down on August 21, 2023, exacerbating reliance on scattered third-party resources. This decline in official stewardship has led to practical consequences, such as removal from major repositories; , for example, excised MLDonkey from its unstable branch on February 6, 2023, citing unresolved maintenance issues. Similarly, it has been dropped from other package managers like Armbian's repositories around mid-2023, reflecting broader challenges in keeping the aligned with evolving dependencies and standards. While patches mitigate some obsolescence, the lack of a unified development path has diminished MLDonkey's prominence amid competition from more actively maintained P2P clients.

Technical Architecture

Core Engine and Daemon Design

The core engine of MLDonkey operates as a standalone daemon process, primarily implemented in the programming language for efficient handling of concurrent network operations. Designated as mlnet, the daemon executes in the background, independently managing file discovery, downloads, uploads, and sharing without requiring a graphical interface. This design enables continuous 24/7 operation on diverse platforms, including servers and resource-limited devices, by decoupling the computational core from user-facing components. The daemon's architecture centers on a modular structure that abstracts multi-protocol support into interchangeable network handlers, allowing simultaneous connectivity to networks such as eDonkey (including Overnet and extensions), BitTorrent (with ), and direct HTTP/FTP sources. Core components include peer management for connection establishment and maintenance, chunk-based file transfer logic to optimize bandwidth and partial downloads, and a unified file queue system that persists state across restarts via configuration files and a dedicated downloads directory. This separation ensures the engine focuses on low-level protocol compliance and , while higher-level features like search indexing and are configurable at runtime. Interaction with the daemon occurs through lightweight, protocol-agnostic interfaces: a console (default port 4000) for direct command issuance, an integrated HTTP server for browser-based control, and a binary protocol socket for third-party graphical frontends. These interfaces expose core functions like adding files, querying status, and adjusting parameters without embedding UI logic in the engine itself, promoting and extensibility. The foundation provides functional paradigms suited to the daemon's event-driven nature, minimizing overhead in thread-safe operations despite the language's single-threaded runtime model in versions prior to OCaml 5.0 compatibility efforts.

Protocol Integration and Multi-Network Support

MLDonkey employs a modular daemon architecture in to integrate diverse protocols, allowing the core engine to manage protocol-specific communication layers within a unified backend process. This design separates network handling from download management, enabling the software to interface with multiple protocols simultaneously without dedicated clients for each. Core supported protocols encompass the , including Overnet for serverless peer discovery and (Kad) for distributed hashing and lookup; with (DHT) extensions for enhanced swarm participation; Direct Connect for hub-mediated sharing; and HTTP/FTP for non-P2P direct retrievals. Earlier implementations added and for query flooding, for indexed searches, and FileTP variants, though these have largely obsolesced due to network attrition. Multi-network functionality permits concurrent operation across enabled protocols, with parallel searches aggregating results into a for user selection. Downloads, however, remain network-bound, sourcing from multiple peers within the file's originating protocol to maximize throughput. Networks can be toggled individually via configuration, balancing connectivity against bandwidth constraints, while cross-network file aggregation—envisioned for broader source pooling—has not been realized in releases.

Features

Download and Sharing Mechanisms

MLDonkey divides files into fixed-size chunks to facilitate parallel downloads from multiple peers and sources across supported networks, including eDonkey, Overnet, , , and . A dedicated scheduler optimizes source selection and chunk retrieval by prioritizing available and reliable peers, reducing redundancy and enhancing efficiency. Chunk integrity is verified using cryptographic hashes inherent to protocols like eDonkey, ensuring data accuracy before assembly into complete files. The swarming feature, introduced in version 2.5.30, enables aggregation of chunks from disparate networks for a single file, allowing simultaneous sourcing from eDonkey, , and peers to accelerate completion times. Partial downloads support previewing, permitting users to access playable or viewable content from available chunks without full file assembly. Source discovery occurs via network-specific methods, such as querying eDonkey servers or leveraging decentralized lookups, followed by establishing direct peer connections for transfers. For sharing, users specify directories via configuration, prompting MLDonkey to scan and index files for advertisement on connected networks. Uploads operate through queued requests, where incoming peer demands are processed based on protocol rules, such as eDonkey's credit system that favors peers with prior contributions to encourage reciprocity. Shared files, including incomplete downloads, are offered in chunks to requesters, with dynamic bandwidth allocation balancing slots against priorities to maintain overall throughput. This multi-network sharing extends availability, as indexed files become discoverable across protocols, though rates are user-configurable to prevent resource exhaustion.

Bandwidth and Resource Management

MLDonkey provides configurable bandwidth limits to prevent network saturation and ensure stable connectivity, primarily through options in the downloads.ini edited while the daemon is stopped. The max_hard_upload_rate and max_hard_download_rate parameters set absolute ceilings in kilobytes per second, with a value of 0 indicating no limit; for example, on a 512/128 kbps cable/ connection, low-priority settings might use 2 KB/s upload and 6 KB/s download, while high-priority allows 6 KB/s upload and 12 KB/s download. These limits help maintain ratios essential for reciprocity, as unrestricted uploading can congest lines and degrade overall performance. Users can adjust rates dynamically via the interface on port 4000 or web interface, enabling real-time control without restarting the daemon. Recommendations include reserving bandwidth for non-P2P traffic like , with capped at around 60 KB/s and download at 1 MB/s for a 20 Mbit down/1 Mbit up connection to avoid total saturation. Resource management focuses on CPU and memory optimization, as the daemon can consume significant amounts during intensive operations like source scanning or handling large queues. CPU usage should ideally stay between 2% and 20%, with levels exceeding 50% signaling the need for tuning, such as reducing shared files from 1000 to 200 or disabling unused networks like Overnet or Kademlia. Memory requirements start at 15 MB minimum, but can escalate with queued files; historical versions struggled with 400+ queued items, though updates have mitigated leaks and high consumption. To curb resource demands, options like ED2K-max_sources_per_file limit tracked peers per download (e.g., from 5000 to 1250 on systems with ≤128 MB RAM), while share_scan_interval can extend to 120 minutes or disable scanning entirely. Trade-offs include enabling ip_blocking_descriptions for lower CPU but higher memory, or vice versa; later releases also cap concurrent sources and fix CPU spikes from UDP handling. Monitoring via Unix top command reveals usage patterns, guiding adjustments to prevent overload on low-end hardware.

Cross-Platform Compatibility and Deployment

MLDonkey's core daemon, known as mlnet, is implemented in OCaml, enabling compilation and execution across diverse operating systems without inherent platform-specific dependencies in its primary architecture. It officially supports Unix-like systems such as Linux distributions, FreeBSD and other BSD variants, Solaris, and macOS, as well as Microsoft Windows through precompiled binaries or cross-compilation. MorphOS and legacy systems like BeOS have also received historical support, though maintenance for these is limited. Deployment typically occurs as a headless daemon , allowing remote via built-in interfaces like , a , or HTTP-based controls, which facilitates operation on servers or embedded devices without a graphical environment. Users compile from available on for the most current version, requiring OCaml runtime (versions 4.03 to under 5.0) and dependencies like GTK2 for optional graphical components. Distribution-specific packages exist—such as mldonkey-server in repositories or for macOS—but these are often outdated relative to upstream releases, prompting recommendations to build directly from source for stability and feature access. On Windows, deployment involves running the mlnet.exe executable, often paired with third-party frontends for user interaction. Containerized deployment via Docker has gained traction for simplified setup across platforms, with images incorporating the core daemon and exposing ports for network protocols and control interfaces. This approach mitigates OS-specific compilation issues, supports orchestration on devices like QNAP, and ensures consistent behavior in heterogeneous environments, though it requires mapping volumes for persistent data storage. installations follow standard ports collection methods, emphasizing daemon configuration files for network tuning and multi-protocol integration. Overall, MLDonkey's deployment emphasizes minimal resource footprint, with the daemon configurable to run under low-privilege users and integrate with system init scripts or for automated startup.

User Interfaces

Built-in Control Interfaces

MLDonkey operates as a daemon without a native , instead offering built-in control mechanisms integrated into its core for remote and local management. These include a telnet-based , a web interface accessible via HTTP, and a binary protocol supporting third-party frontends. This design enables unattended operation while allowing users to monitor downloads, configure settings, and manage sharing across supported protocols like eDonkey, Overnet, and . The interface provides a scriptable command-line console for direct interaction, typically accessed via telnet localhost 4000 or remotely if configured. Users can execute commands such as help for listings, set <option> <value> for configuration changes (e.g., bandwidth limits or network preferences), show downloads for status overviews, and kill <id> to stop specific transfers. This interface supports automation through scripts and is lightweight, requiring no additional software beyond a client, though it lacks visual elements and relies on text-based output for details like peer connections and file availability. The web interface, served on port 4080 by default (configurable via set http_port <port> in ), delivers a browser-accessible for graphical control without installing frontends. It displays real-time statistics including active downloads, / rates, connected peers, and search results, with forms for adding links, prioritizing files, and adjusting preferences like maximum connections or friend lists. features include basic via username and password set through commands (e.g., set http_wwwuser <user>), though exposure requires firewall rules to mitigate risks. The interface uses simple with for interactivity, supporting operations across all integrated networks. Additionally, the binary protocol enables communication with external applications, facilitating the development of custom or native GUIs that interface with the daemon without relying on HTTP or . This protocol, documented in MLDonkey's and used by over a dozen frontends, transmits structured data for efficient control of core functions like search queries and file management. As of the last stable release in 2018, these interfaces remain functional in community-maintained builds, though compatibility with modern systems may require patches for dependencies like .

Third-Party Frontends and Modern GUIs

Third-party frontends for MLDonkey extend its core daemon functionality by providing graphical or web-based interfaces that connect via protocols such as , HTTP, or the TCP binary interface, enabling and user-friendly of downloads, searches, and across supported networks. These interfaces emerged due to the command-line nature of the MLDonkey backend, with developers creating alternatives to the basic built-in web and GUIs for improved usability, cross-platform support, and modern features like responsive design. One prominent modern frontend is mldonkey-next, an open-source client that includes a responsive built with Angular and a cross-platform desktop app, primarily tested on but designed for broader compatibility. It connects to the MLDonkey daemon using the TCP binary protocol for efficient control, supporting features like real-time monitoring of transfers and searches without requiring browser plugins. First developed around 2020 and actively maintained into 2025, mldonkey-next addresses limitations in older interfaces by offering a containerized Docker option for easy deployment and integration with modern container ecosystems. Available via Flathub for installations, it emphasizes simplicity and performance for multi-protocol P2P operations. Another web-based option is P2P-GUI, a graphical remote interface that supports MLDonkey alongside other P2P applications, allowing multi-user access through account management layers. Hosted on , it provides browser-accessible controls for queue management and network configuration, prioritizing via user authentication to mitigate risks in remote setups. While not as recently updated as mldonkey-next, it remains functional for users seeking a lightweight, protocol-agnostic frontend without native dependencies. Older third-party GUIs, such as MuLiGUI (a speed-focused web frontend) and RMldonkey (a multiplatform native interface), offer basic alternatives but lack the responsive and container-friendly designs of newer tools. These have seen limited updates since the mid-2010s, reflecting a shift toward web and app-based modernizations in the community. Developers often recommend testing compatibility with specific MLDonkey versions, as frontend-daemon protocol mismatches can occur due to the backend's evolving multi-network support.

Reception and Impact

Adoption and Technical Achievements

MLDonkey experienced initial adoption following its development starting in January 2002, positioning it as the first open-source client capable of accessing the , which attracted users seeking alternatives to amid the rapid growth of in the early 2000s. Its daemon-based architecture appealed particularly to technically proficient users on systems, including distributions, where it was packaged for easy deployment via tools like and integrated into devices such as Thecus NAS systems by 2016. While exact user base figures are unavailable, its presence in open-source repositories and community forums indicates sustained niche usage among developers and power users, with SourceForge reviews highlighting its reliability for multi-network operations despite limited mainstream appeal compared to GUI-heavy clients. Technically, MLDonkey achieved distinction through its multi-protocol integration, enabling simultaneous connections to networks including eDonkey, Overnet, , and , a capability that allowed efficient file assembly from disparate sources and predated broader adoption of hybrid P2P designs. The software's headless server model, controllable via , HTTP, or third-party interfaces, facilitated resource-efficient operation on low-power devices and remote management, reducing overhead compared to client applications with embedded GUIs. Key milestones include the addition of BitTorrent support in version 2.x releases around 2005, enhancing download speeds through protocol-specific optimizations like chunk verification and source exchange, and ongoing up to version 3.1.7 in January 2017, with community forks extending compatibility to modern systems as late as 2024. These features contributed to its reputation for robustness in bandwidth-constrained environments, though adoption waned as centralized alternatives and legal pressures diminished eDonkey's overall network scale from its mid-2000s peak of millions of concurrent users.

Criticisms and Technical Limitations

Despite its multi-network capabilities, MLDonkey has faced criticism for its stagnant development, with the core project largely unmaintained since around , leading to compatibility issues on modern operating systems and distributions such as Bullseye, where it was dropped from repositories. Forks like mldonkey-next have emerged to address this, incorporating modern web interfaces and cross-platform support, but the original codebase suffers from unresolved build failures, such as errors in queue configuration and missing dependencies like libgd on 18.04. This outdated status contributes to frequent user-reported problems, including failure to compile or run on platforms like and , often requiring manual patches or alternative installations. Security vulnerabilities represent a significant limitation, with historical flaws including an absolute path traversal issue in versions 2.8.4 through 2.9.7 that allowed remote to read arbitrary files via double-slash sequences in HTTP requests. Additional risks involved network module bypasses, where files in the web_infos directory could be loaded post-module initialization, potentially enabling unauthorized access, and default empty passwords in certain ebuilds like Gentoo's pre-2.9.0-r3. issued advisories, such as DSA 1739-1 in 2009, to mitigate information disclosure via path traversal, underscoring the software's exposure when unpatched. Users running legacy versions remain vulnerable, as urgent updates have been sporadic and CPU/memory inefficiencies persist even in later releases. Technical constraints include unreliable connection establishment, often resulting in LowID status due to firewall or failures, preventing incoming connections and limiting upload/download efficiency unless ports like 4662 are manually forwarded. issues, such as "too many open files" errors exceeding ulimit defaults (e.g., 5000), can halt operations on resource-constrained systems like devices. The software imposes practical limits on sharing, typically handling more than 1 GB but fewer than 1000 files effectively, with non-guaranteed download rates and ongoing instability in queuing, uploading, and downloading across versions. Configuration complexity exacerbates these, as out-of-the-box setups frequently fail to connect to eDonkey servers without importing .met files or disabling firewalls, leading to critiques of poor usability compared to modern P2P clients. The distribution and acquisition of copyrighted material via peer-to-peer (P2P) networks supported by MLDonkey, such as eDonkey and Overnet, constitute copyright infringement under applicable laws when performed without authorization from rights holders. While the MLDonkey software itself is legal open-source code, users bear direct liability as primary infringers for both downloading and uploading protected files, as P2P protocols inherently involve simultaneous sharing that exposes portions of users' downloaded content to the network. Copyright enforcement entities, including the Recording Industry Association of America (RIAA), have historically monitored these networks to identify and pursue individual uploaders, leading to thousands of lawsuits against U.S. users since the early 2000s for unauthorized sharing of music, films, and software. In the United States, such actions violate the Act (17 U.S.C. § 501), with civil remedies including statutory up to $150,000 per infringed work for willful violations, plus attorney fees; criminal penalties for repeat offenders can reach five years and fines of $250,000 per offense. The (DMCA) facilitates takedown notices to internet service providers (ISPs), potentially resulting in account suspension or termination for repeat infringers. In the , the InfoSoc Directive (2001/29/EC) imposes similar direct liability on users for and communication to the public of unauthorized works, with member states enacting penalties ranging from fines to ; for instance, France's HADOPI authority has issued warnings and pursued disconnections for P2P infringements since 2009. Enforcement against P2P users persists despite technological shifts, as networks like those accessible via MLDonkey remain traceable through IP addresses and shared file hashes, enabling rights holders to automate detection without undue burden. Legal use of MLDonkey is possible for or licensed content, but empirical from network analyses indicate predominant infringement, underscoring the practical risks of exposure to litigation regardless of intent. Jurisdictional variations exist—such as stricter intermediary liabilities in some countries—but user-level remains a core principle, with no safe harbor for decentralized P2P participants.

Documented Security Vulnerabilities and Mitigations

One notable security vulnerability in MLDonkey is CVE-2009-0753, an absolute path traversal issue affecting versions 2.8.4 through 2.9.7, which enables remote attackers to read arbitrary files on the host system by appending a leading double slash ("//") to a in HTTP requests to the web interface. This flaw stems from insufficient input sanitization in the file serving component, allowing traversal beyond the intended directory. Mitigation involves upgrading to MLDonkey 3.0.0 or later, where the path handling was corrected, or applying distro-specific patches such as those released in DSA-1739-1. Another documented issue, CVE-2007-4100, involves a bypass in MLDonkey versions prior to 2.8.0, where the application loads files from the $MLDONKEY/web_infos/ directory after network modules activate, potentially allowing remote attackers to circumvent IP-based access restrictions on the administrative interface. This occurs due to the timing of module initialization relative to web resource loading, enabling unauthorized access to sensitive controls. The was addressed in version 2.8.0 by enforcing restrictions before loading such files, with users advised to restrict interface exposure via firewalls until updated. An earlier cross-site scripting (XSS) vulnerability, CVE-2003-1164, affected MLDonkey 2.5-4, permitting remote attackers to inject arbitrary web scripts or into the web interface via unsanitized URIs reflected in responses. This could lead to or if exploited through the administrative web panel. required updating to subsequent releases beyond 2.5-4, which implemented URI validation, alongside general best practices like disabling the web interface when not in use or binding it to . Distributions have reported packaging-specific issues, such as CVE-2007-5714 in Gentoo's ebuild for versions before 2.9.0-r3, where a "p2p" user account defaulted to an empty password with shell access, risking unauthorized system entry if the service ran as or with elevated privileges. This was resolved by setting a non-empty password in the ebuild revision 2.9.0-r3 and recommending non- execution for the daemon. Overall, mitigations for MLDonkey emphasize running the daemon in a chrooted environment, firewalling exposed ports (e.g., 4080 for web access), and regular updates, though the project's stagnant development since the early limits patches for newly discovered flaws.
