4. date is a string containing the current time with a 1 hour resolution index is a running number starting at 0 If a client can not insert its announcement at an index due to a key collision it increments index and tries again until the announcement succeeded This process is repeated every hour so that a client can assume that clients that haven t been heard from by announcement for the last two hours have gone away 4 12 File Lists File lists are inserted by the clients to enable other clients to search for file File lists contain the local filename the FreeNet key without the freenet prefix the size the number of blocks and the user given rating and comment File lists are inserted to SSK private key freeMule filelist index Inser tion to an SSK key ensures that the file lists can not be manipulated by other clients or malicious parties index is incremented every time a client updates its list of shared files by adding or removing files or directories or by adding or changing a rating or comment of a shared file When a file list has been inserted new announcement information contain ing the now updated index will be inserted Thus by continously scanning for announcement information by other clients a client can keep up with changes in file lists of other clients 4 2 File Download Downloading a file can be accomplished in two ways by using the Download Key Textfield see The Download Key Textfield or by selec
5. download by other clients UPd say that my source code is actually pretty clean and well structured but other people s source is always hard to understand no matter what I peer to peer i e clients communicate directly with each other without some kind of server 4 TECHNICAL INFORMATION 14 In the design phase it has been taken into account that a request for a file that does not exist in FreeNet strains the FreeNet network much more than a request for a file that does exist due to nodes having to forward the request to a number of other nodes until finally being able to conclude that the data is not there opposed to being able to abort a search prematurely due to having found the data In theory the files a client inserts are requested by almost every other running freeMule client so that the data should spread very quickly through the FreeNet network in turn allowing nodes to find it almost immediately Of course that is only valid if a sufficient number of nodes are running and the network is working well 4 11 Announcements When a client starts it knows nothing about other clients In order to com pensate the lack of a server telling the client about other clients clients insert Announcement Information This information contains some client related properties like the name the user choose the identity of the client and the latest version of it s file list Announcements are inserted to KSK freeMule announcement date index
6. file you want to down load is pretty difficult When using The Freedom Engine you have to search every freesite for a link to the file you are interested in This can be a lengthy process and might not result in what you want Also as desribed earlier files that are not requested tend to drop out of FreeNet As a solution to these problems I came up with the idea of freeMule freeMule as can already be deduced by its name is a file sharing application modelled after the popular eDonkey network client eMule The key in down loading a file with eMule is that as soon as you re downloading a file you re also uploading it to other clients who are interested in the same file Obviously eMule works with TCP and UDP connections allowing bi directional real time communication between clients and servers freeMule does not have this possibility so some mechanisms used in eMule had to be adapted to the FreeNet way Fortunately FreeNet also offers some advantages over classical file sharing content has to be stored in FreeNet so as soon as a block of data is uploaded to FreeNet it is available to all users interested in that block at the same time and at no cost for the original inserter Searching for a file in eMule works by sending a query string to the server one is connceted to The server has all a list of files of all clients that are connected to it As you don t connect to a server in freeMule the clients store their file lists in Fr

UI you are presented with when freeMule starts I have tried to make the user interface as sensible and intuitive as possible but I am only a programmer not a user interface designer So if the interface is flawed in some way forgive me and submit a patch 2 1 The Main Window freeMule s main window is what you see when you start freeMule In the upper half it contains the menu bar a toolbar and a tabbed panel In the lower half you can see the messages window and the key download textfield The following sections will describe the functions in the menu and the toolbar and all panels that can be seen by selecting the corresponding tab from the tabbed panel 2 THE USER INTERFACE 5 2 2 The Toolbar The toolbar has contains a couple of functions that can also be accessed from the menu As those functions behave exactly the same way regardless from where they are executed no distinction between the source of the action is made 2 2 1 The Connect Button This button starts freeMule More exactly all the services are started 2 2 2 The Disconnect Button This button causes freeMule to stop All running services are stopped which may take some time e g the download service finishes all blocks it is currently requesting first 2 23 The Node Button Pops up the node dialog see The Node Dialog This button is only activated when freeMule is not running 2 2 4 The Preferences Button Pops up the preferences

16. eeNet Project The FreeNet Project has been around for quite some time now FreeNet in short is a large distributed encrypted hard disk spread over the internet Whenever a document is inserted into FreeNet it is spread over several FreeNet nodes creating redundant copies When a document is then requested it is further spread across the nodes in the request chain When a FreeNet node runs out of local disk space it forgets the oldest doc ument it has in its store Thus not requested content tends to drop out of FreeNet after a while This is the only way content can disappear from FreeNet there is no way to specifically delete a file Other features inherent in the design of FreeNet are inserter anonymity and requester anonymity based on plausible deniability Though it is possible to trace a request be it insert or retrieval to your node nobody can 1A FreeNet node is the program you run on your computer to access FreeNet More exactly the document that was not accessed for the longest time 1 INTRODUCTION 3 determine for sure that you inserted or requested the document in question There is always the possibility that your node merely forwarded the request for some other node A disadvantage of FreeNet s design is the impossibility to search content or to create bidirectional real time communication comparable to a TCP connec tion 12 freeMule Because FreeNet can not be searched for files locating a
