  • I've installed SuSE 9.3 on a Notebook HP Nx7000 and a AMD desktop without any major difficulties except the fact that for some legal reasons, Novel has removed the ability of SuSe to play out the box any Divx, Xvid, mp3. In fact If You have a acess to internet, the online update tool may resolve some of these issues (You will have to download what Novel call "Multimedia pack" ). After using 2 years long SuSE 9.0, 9.1, 9.2 and now 9.3 I found pathetic that I still need to remove this crappy noatun, kaffeine and xine because they simply do not work as good as Mplayer or even better Videolan (VLC). Note that both Videolan, or VLC can not be install through YaST, and I think that it is really a big mistake.
    So let repair this by:

    • Installing APT-GET packaging system (a lot simpler than YaST as It deal with package conflicts!!!), First read this page, then If You are interested read on :-)
    • Decode encrypted DVD  under Suse 9.3
    • Install Videolan (VLC), the best multiplattform video player

     Before deciding to buy it, download it (FTP source are here), or starting Your favorite Bittorent client, You can

  • Introduction

    This talk will be about why complete Decentralization and Immutability matter for public block chains, and why it is impossible to have one without the other. This will be used as the basis to discuss the consequences of the recent Ethereum Hard Fork, and what it could mean for the viability and integrity of the platform and its dapp developers.

  •  Freenet is free software which lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack.
    Communications by Freenet nodes are encrypted and are "routed-through" other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
    Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.

  • GNUnetis a framework for secure peer-to-peer networking. The primary application implemented within the GNUnet framework is anonymous censorship-resistant file-sharing.
    The goal of the GNUnet project is to provide an infrastructure for secure peer-to-peer networking. All communication in GNUnet is authenticated and link-to-link encrypted. The economic model makes attacks on the network harder since the economics can be used to control resource usage. GNUnet peers exchange messages using a pluggable transport service abstraction. Currently, transport services based on UDP, TCP, HTTP and SMTP are available. The GNUnet core provides mechanisms to perform resource allocations for CPU, bandwidth and storage space. The core enforces resource limitations set by the user. GNUnet does not rely on any centralized services. New Peer-to-Peer protocols can be easily implemented on top of the basic GNUnet infrastructure. Current protocols include anonymous file sharing, a trivial chat protocol, message throughput benchmarking and network topology visualization.

  •  Mute is a file sharing network that uses virtual addresses (instead of IP addresses) and ant-inspired routing algorithms to protect the privacy of both downloaders and uploaders.

    • MUTE protects your privacy by avoiding direct connections with your sharing partners in the network. Most other file sharing programs use direct connections to download or upload, making your identity available to spies from the RIAA and other unscrupulous organizations.
    • Ants display collectively intelligent behavior when foraging for food or fighting off predators. Each ant in the colony acts in a rather simple way, but together they end up doing something clever, like discovering the shortest path between their ant hill and a food source. MUTE's routing mechanism is inspired by ant behavior.

  • Zoogmo is secure and easy to use. It operates by backing up your data over the Internet or within a LAN to your own computers or the computers of your trusted friends, family and colleagues.
    Before your files leave your computer, they are fully encrypted and remain that way crossing the Internet and while stored on your partners’ computers. No one but you, neither Zoogmo nor your backup partners, has access to your data. In fact, they won’t even be able to tell what types of files you are storing on their computer.

    zoogmo.1

    So lets say you have 10 GB worth of data you don't want to loose, most of your friends have some spare disk to give you if you let them also backup their data on your disk. this is where Zoogmo can be useful.

    Data you are storing by your friend can not be read, change or viewed, and your backup can be spawn on many friends (nodes). It's peer to peer nature let Zoogmo go through firewall and is quite network efficient. It also create a kind of backup community that is sharing not only disks but also bandwidth.

    The added value of Zoogmo is that anybody has spare disk, and that distributed backups are more resilient to extraordinary events like fire, theft, short circuit, disk crash.

    If you do not have enough friends :-) or want to have more node to spare your data, the tool allow you to find anonymous (you just see their login) partner. Anonymous partner have a big disadvantage as many of them can disappear from one day to the other simply because they may simply remove Zoogmo of their computer. Currently the tool only run under windows but this kind of tools is quite common now.

  • Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you anonymize web browsing and publishing, instant messaging, IRC, SSH, and more. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features....
    It use the principle of mixing all web request of all users into a huge distributed network of servers, called onion routers. Instead of taking a direct route from source to destination, data packets on the Tor network take a random pathway through several servers that cover your tracks so no observer at any single point can tell where the data came from or where it's going.  It is working more or less like JAP

  • Good
    + Unix based (apache software)
    + telnet interface for advance user with a full CLI
    + a lot of functionnaliies, every protocol is available.
    + Very fast switching. According to Tom's hardware one of the fastest in its class.
    + Very configurable (real business class router not home consummer crap)
    + Built in USB and 1394 FTP server support
    + Nice GUI interface,
    + SUPER stable under emule Load!!!! 1000 connections wthout any loss of performances. A restart each 6 months or less!!!
    + affordable: 90 (USR9105)  to 110 euro (USR 9106)
    + not so much bios update but as I said before a lot of functionnalities and soooooo stable

    But
    - Users guide is very bad
    - GUI and Bios only available in english
    - Is a  little bit tricky to get configured - No explnantion of technical terms in manual or interface

    Setup notes for emule:
    Navigate to security> access control > new and create a new user service rule:
    name: emule
    desc: emule
    TCP any -> 4662
    TCP any -> 4711
    UDP any -> 4672
    UDP any -> 4673
    UDP any -> 4661
    UDP any -> 4665

    2. navigate to security > local servers > new and setup the machine on your lan running emule to use the service you just set up for emule.

    Be sure to set you emule client system as a static IP so the router always assigns it the same IP address. This can be done by fixing the IPadress in windows control panel. you may also play with the CLi to achieve the same result, Here I want to assign the adress 192.168.1.3 to the pc with the mac adress 00:00:00:00:00:00
    telnet 192.168.1.1
    arp add 192.168.1.3 00:00:00:00:00:00
