SUMI Anonymous P2P

SUMI is a new file sharing program that aims for total anonymity for the uploader SUMI is a new file sharing program that aims for total anonymity for the uploader. It is a work in progress; although anonymous file transfer works there are some rough edges. SUMI is the first P2P program to use IP spoofing with proxied acknowledgement.

No proxies needed = no slow down
Resuming
Cross-platform client GUI

[edit]News
2005-09-15: Summer is over. Development will proceed slowly as I will no longer have all day to work on SUMI. Sorry. Feedback is, as always, appreciated. Interested programmers even more so. I will be back... --Shellreef 06:46, 16 Sep 2005 (BST)

P.S.: The (unreleased) code in Subversion adds scripting support and the allows the client to join multicast groups.

2005-09-12: 0.8.14 is out, featuring: more bugfixes, CRC-32 in every packet, SHA-1 for file verification, and an improved uninstaller. This is the first release with the source code in Subversion. Due to the CRC-32 and SHA-1, the protocol is backwards-incompatible, so you'll need to upgrade in order to access the sample servers.

2005-09-01: 0.8.13 released, notably featuring:

Many bugfixes
Torrent-like .sumi files--see sample files above
WinPcap is included with installer to simplify installation
modirclib is back, with full crypt_req support
Drag-and-drop support (can drop a .sumi file onto the sumigetw window to open it)
GUI enhancements: upgraded to wxPython 2.6.1.0, add context-menu options to resume and abort
Additionally, the Tor and irclib sample SUMI servers are back up.

2005-08-30: Moved SUMI Wiki to BerliOS. Let's hope it is faster...

2005-08-27: Created this Wiki, powered by MediaWiki, hosted on SourceForge

2005-08-25: Temporarily shutdown the sample server due to MTU/MSS incompatibilities introduced in CVS. Will be restored with next release.

2005-08-21: 0.8.12 released! Featuring full file data encryption, and the ability to use Tor (http://tor.eff.org/) as a transport. A sample server should be up soon.

2005-07-31: 0.8.11 is now out, with sharing integrated within the GUI and optional request encryption

2005-07-02: 0.8.10 released, featuring Windows 95/98/Me sumiserv compatibility, UDP checksums, optional Ethernet address spoofing, a better transport plugin mechanism for sumiserv, and AIM support in sumiserv.

2005-06-20: development resumed

2005-06-15: #sumi moved to irc.xtc-dreams.com and after many months, the sample SUMI server sumi-00 is back up.

Using a NAT? As of v0.8.5, a new program, rawproxd is included to run on NATs (particularly the WRT54GS) to enable SUMI serving.

Limitations: None
