  • Magic-Wormhole - makes it possible to get arbitrary-sized files and directories (or short pieces of text) from one computer to another. The two endpoints are identified by using identical “wormhole codes”: in general, the sending machine generates and displays the code, which must then be typed into the receiving machine.The codes are short and human-pronounceable, using a phonetically-distinct wordlist. The receiving side offers tab-completion on the codewords, so usually only a few characters must be typed. Wormhole codes are single-use and do not need to be memorized.

  • - a tool that allows any two computers to simply and securely transfer files and folders. There are many tools that can do this but AFAIK croc is the only tool that is easily installed and used on any platform, and has secure peer-to-peer transferring, and has the capability to resume broken transfers. Note: A new WebRTC version is in progress.

  • - Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance. currently supports the s3 (Amazon S3), gdrive (Google Drive) providers, and local file system (local).

  • - a WebRTC based file exchange software.It allows to share a file directly between two computers, without the need of a third party.
gfile send --file filename



scp -P [port] file.txt user@remotehose:~/file.txt

When scp on remote is initiated, it done so with -t flag, which is undocumented but might be required for precise command persmission configuration.



  • UDPcast - a file transfer tool that can send data simultaneously to many destinations on a LAN. This can for instance be used to install entire classrooms of PC's at once. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities: it won't take longer to install 15 machines than it would to install just 2.


  • Tsunami UDP Protocol: A fast user-space file transfer protocol that uses TCP control and UDP data for transfer over very high speed long distance networks (≥ 1 Gbps and even 10 GE), designed to provide more throughput than possible with TCP over the same networks.


  • - a command-line tool that allows sharing files between devices directly over Wi-Fi. Its unique feature is that it is protocol-compatible with Apple AirDrop which allows to share files with Apple devices running iOS and macOS. Currently (and probably also for the foreseeable future), OpenDrop only supports sending to Apple devices that are discoverable by everybody as the default contacts only mode requires Apple-signed certificates.




  • croc - a tool that allows any two computers to simply and securely transfer files and folders. AFAIK, croc is the only CLI file-transfer tool does all of the following: allows any two computers to transfer data (using a relay); provides end-to-end encryption (using PAKE); enables easy cross-platform transfers (Windows, Linux, Mac); allows multiple file transfers; allows resuming transfers that are interrupted; local server or port-forwarding not needed; ipv6-first with ipv4 fallback

File sync

See also SaaS#Storage, Backup



  • lsyncd - designed to synchronize a local directory tree with low profile of expected changes to a remote mirror. Lsyncd is especially useful to sync data from a secure area to a not-so-secure area. Lsyncd watches a local directory trees event monitor interface (inotify or fsevents). It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes. By default this is rsync. Lsyncd is thus a light-weight live mirror solution that is comparatively easy to install not requiring new filesystems or block devices and does not hamper local filesystem performance.


  • inosync daemon leverages the inotify service available in recent linux kernels to monitor and synchronize changes within directories to remote nodes.



  • Syncany is an open-source cloud storage and filesharing application. It allows users to backup and share certain folders of their workstations using any kind of storage, e.g. FTP, SFTP, WebDAV, Samba, Amazon S3 or Google Storage. While the basic idea is similar to Dropbox, Syncany is open-source and additionally provides data encryption and more flexibility in terms of storage type and provider.


  • Syncthing - Open Source Continuous File Synchronization. Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet. This is the Syncthing project which pursues the following goals: Define a protocol for synchronization of a folder between a number of collaborating devices. This protocol should be well defined, unambiguous, easily understood, free to use, efficient, secure and language neutral. This is called the Block Exchange Protocol. Provide the reference implementation to demonstrate the usability of said protocol. This is the syncthing utility. We hope that alternative, compatible implementations of the protocol will arise. [6]

The discovery mechanism can take a minutes or two to kick in.

  • Port 22000/TCP (or the actual listening port if you have changed the Sync Protocol Listen Address setting.)
  • Port 21027/UDP (for discovery broadcasts on IPv4 and multicasts on IPv6)

vim ~/.config/syncthing/config.xml

Local only access;

<gui enabled="true" tls="false">

No whitelist;

<gui enabled="true" tls="false">

Delete the username and password entries from config.xml to reset the login details (do that quickly though!).


gtk2 gui is a bit dodge, drops any ssh args given to it.

syncing requires a manual start.



  • Seafile - an open source cloud storage system with features on privacy protection and teamwork. Collections of files are called libraries, and each library can be synced separately. A library can also be encrypted with a user chosen password. Seafile also allows users to create groups and easily sharing files into groups.


  • git-annex allows managing files with git, without checking the file contents into git. While that may seem paradoxical, it is useful when dealing with files larger than git can currently easily handle, whether due to limitations in memory, time, or disk space. git-annex is designed for git users who love the command line. For everyone else, the git-annex assistant turns git-annex into an easy to use folder synchroniser.



DirSync Pro

  • DirSync Pro is a small, but powerful utility for file and folder synchronization. DirSync Pro can be used to synchronize the content of one or many folders recursively. Use DirSync Pro to easily synchronize files from your desktop PC to your USB-stick (/Externa HD/PDA/Notebook, ...). Use this USB-stick (/Externa HD/PDA/Notebook, ...) to synchronize files to another desktop PC. Using DirSync Pro you can make incremental backups. In this way you'll spare lots of time because you don't have to copy all the files each time you want to update your backup; only new/modified/larger files would be copied. DirSync Pro provides some preconfigured modes (e.g. Mirror, Backup, Contribute, ?) for common synchronization and backup tasks and some custom modes in which the user could set up the synchronization behavior to meet specific wishes.


  • Conduit - a synchronization application for GNOME. It allows you to synchronize your files, photos, emails, contacts, notes, calendar data and any other type of personal information and synchronize that data with another computer, an online service, or even another electronic device. Conduit manages the synchronization and conversion of data into other formats


  • Csync2 is a cluster synchronization tool. It can be used to keep files on multiple hosts in a cluster in sync. Csync2 can handle complex setups with much more than just 2 hosts, handle file deletions and can detect conflicts. It is expedient for HA-clusters, HPC-clusters, COWs and server farms.


  • bfsync - a file-synchronization tool which allows to keep a collection of big files synchronized on many machines. To do this, bfsync maintains a global and local history of changes; every time the file collection is changed on one machine, an entry in the local history is made. Bfsync allows to automatically merge this local history with the global history where possible, and offers manual conflict resolution in cases where this is not possible. Due to history synchronization, each bfsync checkout knows precisely which files are part of the file collection. Therefore, it can determine which file contents (data blobs with SHA1 contents) are present in a checked out repo, and which are missing. The main interface to bfsync is a FuSE filesystem, so it is possible to manage your data with a file manager or copy new data into the repository using rsync. As soon as you "commit" the changes, they are entered into the local history and if you "push/pull" the changes, they become part of the global history.

Bittorrent Sync

Ubuntu One


  • Pydio - an open source software that turns instantly any server (on premise, NAS, cloud IaaS or PaaS) into a file sharing platform for your company. It is an alternative to SaaS Boxes and Drives, with more control, safety and privacy, and favorable TCOs.


  • - a small but smart script that does 2-way directory synchronization. It uses rsync to do efficient data transfer and tracks local file creation/removal to avoid known rsync problem when doing 2-way syncing with deletion. bitpocket can use any server which you have ssh access to for its central storage. If you have gigabytes of free disk space on your hosting server you can finally make use of it.




  • - a data distribution tool with a version control feature for tracking changes and publishing datasets. It is primarily used for data-driven science, but it can be used to keep track of changes in any data set. As a distributed revision control system it is aimed at speed, simplicity, security, and support for distributed, non-linear workflows.

[10]



  • FileSender - a web based application that allows authenticated users to securely and easily send arbitrarily large files to other users. Authentication of users is provided through SimpleSAMLphp, supporting SAML2, LDAP and RADIUS and more. Users without an account can be sent an upload voucher by an authenticated user. FileSender is developed to the requirements of the higher education and research community.The purpose of the software is to send a large file to someone, have that file available for download for a certain number of downloads and/or a certain amount of time, and after that automatically delete the file. The software is not intended as a permanent file publishing platform

Firefox Send


  • Lufi - stores files and allows you to download them.Is that all? No. All the files are encrypted by the browser! It means that your files never leave your computer unencrypted. The administrator of the Lufi instance you use will not be able to see what is in your file, neither will your network administrator, or your ISP.The encryption key part of the URL is a anchor (Cf. Fragment Identifier), that means this part is only processed client-side and does not reach the server. Lufi is licensed under the terms of the AGPL.


See Net media#Usenet

  • Lidarr
    • - a music collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new tracks from your favorite artists and will grab, sort and rename them. It can also be configured to automatically upgrade the quality of files already downloaded when a better quality format becomes available.

Encrypted / anon


  • WASTE is an anonymous, secure, and encryped collaboration tool which allows users to both share ideas through the chat interface and share data through the download system.

The suggested size for a WASTE network (referred to as a "mesh" by users) is 10-50 nodes, though it has been suggested that the size of the network is less critical than the ratio of nodes willing to route traffic to those that are not.


  • Freenet - Share files, chat on forums, browse and publish, anonymously and without fear of blocking or censorship! While users can insert data into the network, there is no way to delete data. Due to the anonymity, no node knows who is the 'owner' of a piece of data. The only way data can be removed is if users don't request the data.


  • RetroShare is a Open Source cross-platform, Friend-2-Friend and secure decentralised communication platform. It lets you to securely chat and share files with your friends and family, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication. RetroShare provides filesharing, chat, messages, forums and channels




  • OFF is a highly connected peer-to-peer distributed file system. The unique feature of this system is that it stores all of its internal data as meaningless multi-use data blocks. In other words there is not a one to one mapping between a stored block and its use in a accessed file. Each stored block is simultaneously used to access many different files. Individually however, each block is nothing but arbitrary digital white noise.

Free Haven Project

  • Free Haven Project aims to deploy a system for distributed, anonymous, persistent data storage which is robust against attempts by powerful adversaries to find and destroy any stored data. This model of decentralized system has been classified as peer-to-peer by recent popular media.
