It's extremely easy to use - downloads are started by clicking on hyperlinks. Whenever more than one person is downloading at once they send pieces of the file(s) to each other, thus relieving the central server's bandwidth burden. Even with many simultaneous downloads, the upload burden on the central server remains quite small, since each new downloader introduces new upload capacity. Windows web browser support is added by running an installer. A prebuilt one is available, but instructions for building it yourself are in BUILD.windows.txt Instructions for Unix installation are in INSTALL.unix.txt To start hosting - 1) start running a tracker First, you need a tracker. If you're on a dynamic IP or otherwise unreliable connection, you should find someone else's tracker and use that. Otherwise, follow the rest of this step. Trackers refer downloaders to each other. The load on the tracker is very small, so you only need one for all your files. To run a tracker, execute the command bttrack.py Here is an example - ./bttrack.py --port 6969 --dfile dstate --dfile is where persistent information is kept on the tracker across invocations. It makes everything start working again immediately if you restart the tracker. A new one will be created if it doesn't exist already. The tracker must be on a net-addressible box, and you must know the ip number or dns name of it. The tracker outputs web logs to standard out. You can get information about the files it's currently serving by getting its index page. 2) create a metainfo file using btmakemetafile.py To generate a metainfo file, run the publish btmakemetafile and give it the file you want metainfo for and the url of the tracker ./btmakemetafile.py myfile.ext http://my.tracker:6969/announce This will generate a file called myfile.ext.torrent Make sure to include the port number in the tracker url if it isn't 80. This command may take a while to scan over the whole file hashing it. The /announce path is special and hard-coded into the tracker. Make sure to give the domain or ip your tracker is on instead of my.tracker. You can use either a dns name or an IP address in the tracker url. 3) associate .torrent with application/x-bittorrent on your web server The way you do this is dependent on the particular web server you're using. You must have a web server which can serve ordinary static files and is addressable from the internet at large. 4) put the newly made .torrent file on your web server Note that the file name you choose on the server must end in .torrent, so it gets associated with the right mimetype. 5) put up a static page which links to the location you uploaded to in step 4 The file you uploaded in step 4 is linked to using an ordinary url. 6) start a downloader as a resume on the complete file You have to run a downloader which already has the complete file, so new downloaders have a place to get it from. Here's an example - ./btdownloadheadless.py --url http://my.server/myfile.torrent --saveas myfile.ext Make sure the saveas argument points to the already complete file. If you're running the complete downloader on the same machine or LAN as the tracker, give a --ip parameter to the complete downloader. The --ip parameter can be either an IP address or DNS name. BitTorrent defaults to port 6881. If it can't use 6881, (probably because another download is happening) it tries 6882, then 6883, etc. It gives up after 6889. 7) you're done! Now you just have to get people downloading! Refer them to the page you created in step 5. BitTorrent can also publish whole directories - simply point btmakemetafile.py at the directory with files in it, they'll be published as one unit. All files in subdirectories will be included, although files and directories named 'CVS' and 'core' are ignored.

Install Python 2.2 - Make sure ProjectBuilder knows where to find libpython2.2a Update the library's location in Groups&Files/BitTorrent/Frameworks/LinkedFrameworks Update Targets/BitTorrent/BuildSettings/SearchPaths/Libraries - IMPORTANT: You can't use Python.framework Use a regular python install (fink is ok!) 2. Build BitTorrent - click hammer icon The freeze.py script copies the dependent python modules from your python distribution into the app wrapper. I think this script will work independently of your particular python installation but I haven't tested it on any other systems. ** The project configuration could be better. ---------------- HACKING GUIDE The thing that makes BT-OSX not so straightforward is on the Mac you don't create a whole new instance of the app for each download (DL). That means each DL runs in it's own thread. BT uses callbacks for display updates but in Cocoa you con't reliably draw from any thread but the main thread or your app will crash. So what we do is use an NSConnection so messages sent from a DL thread to it's DL window are posted in the main thread on the next turn of the main event loop. This complicates setting up the DL but once things are setup communication between the python threads and the DL window controller is a simple ObjC message send. Basically, a pair of mach ports is created and the DL window is registered in the main thread's connection. Then the ports are passed into the DL thread and the DL thread gets a proxy to the DL window. When the DL thread messages it's window, NSConnection transparently packs up, sends over a Mach port, unpacks, and dispatches the message on the main event loop with the return value sent to the originating thread if necesary. components: BTAppController.m - App delegate, loads the DLWindow nibs and starts DLs DLWindowController.m - each DL window has one of these as it's delegate, it is messaged by the python callbacks to update the DL window BTCallbacks.h - ObjC protocol for messages the DLWindowController - responds to; chooseFile, display, and finished callbacks.. callbacks.m - Python object written in C, it's methods are passed into BitTorrent as callbacks. It encapsulates the connection to the DLWindowController and makes the ObjC calls to it. here's how it goes: main.m initializes the Python interpreter before starting the regular Appkit stuff when BTAppController starts a new DL, it loads the DLWindow nib and instantiates a DLWindowController. BTAppController then makes a pair of NSPorts and an NSConnection and registers the DLWindowController instance as the root object. BTAppController makes Python Event object for cancelling the download, then starts a new thread passing the ports and event flag The new thread uses the ports to create an NSConnection to the DLWindowController, creates a Python proxy object (defined in callbacks.m,) that encapsulates the DLWindowController NSProxy then sets up the arguments for the BT download. Now when BT calls back, the python callback functions message the DLWindowController via the NSConnection, with the messages being dispatched on the main event loop...

Sorry... InternetExplorer users: You must launch BitTorrent with InternetExplorer NOT RUNNING in order to register as a helper app. This only needs to be done once. Safari: Safari doesn't automatically hand the torrent file off to BitTorrent. Open the torrent file to start the download. Mozilla: Restart Mozilla after launching BitTorrent for the first time. OmniWeb: OmniWeb doesn't auto-launch BT. Just double-click the .torrent file in the download panel or otherwise open the .torrent file to get things started. Guide to Fast Downloads ----------------------- The name of the game is connecting to as many peers as possible. If you are behind a NAT or firewall, the single thing that will make the biggest difference in your download speed is to reconfigure your NAT/firewall to allow incoming connections on the ports that BT is listening to (it uses a new port for every download, starting at the minimum you specify.) Then all the other peers behind a NAT or firewall will connect to you so that you can download from them. BitTorrent uses "tit for tat" for deciding which peer to upload to. In general terms, the client uploads to the peers that it is downloading from the fastest. This is why there can be a delay after connecting to peers before downloading begins; you have nothing to upload to other peers. The torrent typically bursts to life once your client gets a complete piece or two. If there is excess bandwidth available, perhaps because many peers left their window open, then you can get good download rates without uploading much. If you are on a very fast connection and think you could be downloading faster, try increasing the maximum number of uploads; by uploading to more peers you may end up downloading from more peers. Give the client a few minutes to "settle" after tweaking it. The client uses one upload "slot" to cycle through peers looking for fast downloads and only changes this slot every 30 seconds. Release Notes Version 3.3a 2003/11/07 ---------- Recompiled with XCode, works on Pathner Release Notes Version 3.3 2003/10/10 ---------- Latest BitTorrent: more hard drive friendly file allocation less CPU consumption many tweaks Internationalization: Better handling of extended characters in filenames. Dutch translation contributed by Martijn Dekker Partial French translation contributed by ToShyO Fixed Bugs: opened file descriptor limit removed illegal characters from Rendezvous advertisements, not compatible with 3.2! Release Notes Version 3.2.2a 2003/05/31 ---------- somehow a typo snuck in unnoticed Release Notes Version 3.2.2 2003/05/30 ---------- Latest BitTorrent Fixed bug where opening multiple torrent files at once caused a deadlock New Features: Preferences for minimum/maximum port and IP address Displays number of peers Displays total uploaded / downloaded Adjustable max upload rate and max uploads (not surprisingly, this was the most requested feature) Rendezvous tracking finds peers on the same side of the firewall and allows "trackerless" operation in the local domain Cancel button for torrent generation Release Notes Version 3.1a ---------- Fixed a bug where torrents larger than about 2 gigabytes would fail. These builds do not seem to work on 10.1, the cause is being investigated. For now you need 10.2 "Jaguar" Release Notes Version 3.1 ---------- This release has the latest BitTorrent and also UI for generating torrent files. Checking the "create a torrent file for each file/folder in this folder..." will create a torrent file only if one does not already exist. Also, it only creates torrents for the files/foldes in the top level of the chosen folder.
