Distributed Storage Grid
From 25C3 Public Wiki
The idea is to build an experimental Distributed Storage Grid at 25C3 using the Least-Autority Filesystem LAFS-Tahoe.

[edit] Introduction
Tahoe is a secure, decentralized, fault-tolerant filesystem. All of the source code is available under a Free Software, Open Source licence. This filesystem is encrypted and spread over multiple peers in such a way that it remains available even when some of the peers are unavailable, malfunctioning, or malicious. The one-page summary explains the unique properties of this system.
[edit] Installation instructions
Quickstart using easy_install tool as root:
easy_install allmydata-tahoe
You can find detailed instruction on the project install.html page.
Open your firewall for inbound tcp trafic on port $(cat /home/tahoe/.tahoe/client.port).
[edit] Platform specific hacks
[edit] MacOS X Leopard
sudo easy_install -U setuptools sudo /usr/local/bin/easy_install allmydata-tahoe
[edit] Ubuntu intrepid
If you are using ufw, allow access to tahoe client port for other people to connect to your node.
sudo ufw allow $(cat ~/.tahoe/client.port)
[edit] Connecting to the grid
1. Create an new client.
tahoe create-client
2. Edit ~/.tahoe/tahoe.cfg to set the introducer furl and your nickname
echo MyNaMe > ~/.tahoe/nickname echo pb://qu5tmeahks4s3ndwndhhblqdzgu4kzwk@213.251.167.55:4790,127.0.0.1:4790/introducer > ~/.tahoe/introducer.furl
3. Optionally set quota for storage used on your computer, 10 GB limit in this example.
echo $[10*1024*1024*1024] > ~/.tahoe/sizelimit
4. Start tahoe !
tahoe start
5. Browse through the available files and upload stuff at following location.
http://localhost:8123/uri/URI%3ADIR2%3Aa6e2i3itbehus5mvdssl4irzry%3Atroswo2gpqw2esnv7lnczbllmdiinzq7aamecafgt5hywk5gyppq/
NB: Firefox users using the Torbutton extension might suffer from this bug.
