Bittorent

Post subject:	Bittorent
I have a couple questions: How, exactly is it supposed to work? What issues would i have using WinXP Pro sp2, firefox, and a router with firewall? I downloaded an installer from http://bittorrent.com/ and ran it. I got a prompt that said it was installed. Then i went to a copule sites that I found links for in the "ultimate essential program list" But when i try to download something, the progress doesnt move, its been at 0% for about 5 minutes now, and it says "connecting to peers"

Post subject:
I sometimes get that also. I believe that bittorent works by spreading out the bandwidth among all the peers who are conncected that have the same file that you are trying to download. I think this makes it either run faster or more relieable. I personnal;ly like the azureus bittorent client better then the one from bittorent.com (although I have used it only very briefly). www.azureus.net I believe that site also has a description of how bittirent works.

ok si i tried to download a small file, a trailer instead of a full movie, and it seems to be working to far. Would i get better performance by tweaking with the firewall?

Turn on port forwarding and you shouldn't have any more slow download speeds.

Ok, but what are the security implications of doing that?

Just open up the ports you need, don't DMZ anything, and there shouldn't be any real risk.

Post subject:
what do you mean by 'DMZ"?

Author:	rdrake [ Sun Oct 03, 2004 8:55 pm ]
Post subject:
DMZ basically opens your computer up to the internet so there's little to no protection from your router's firewall. It's as if you don't even have the router there.

Post subject:
What kind of speed should I expect.. ? the trailer only went to about 30kbps, which is what about what I would get on winmx from a single source, although its gone a lot higher when i was downloading a lot of stuff from lots of good sources..

Author:	rdrake [ Sun Oct 03, 2004 8:59 pm ]
Post subject:
It really depends on how many sources there is for the thing you're downloading. I've gotten up to 120 kbps which is the average for my connection, but I've also gone as low as 1 kbps.

All this talk is about a router, correct? So, if your router is any good, you should have a setting burried somewhere in your router's port-forwarding menu that is labled (something like): "Application-Triggered Port Forwarding". This closes the ports when un-used and only opens them when an application from within the network (and only the specified computer) calls for those ports. This is exactly what I have done. The only ports that need "Persistent Forwarding" are thing like web-servers, or the likes. But for BitTorrent, "Application Triggered" is your safest bet. As for Azureus, what, you don't have 13 MBs of memory to spare? And although one megabyte of RAM it may not consume, I'd rather let it have the extra memory, and deal with a client of higher quality than that of a light-weight, stripped down, python version of any other. I need the features that are included in Azureus; you may not. I'm just saying, for a nub: Azureus is easy to use. For someone that uses BitTorrent for all their P2P action: it's got nice advanced functionality. EDIT: Someone already said what DMZ is (De-Militarized Zone). In a nutshell, think of the router's firewall as a small army protecting against port-scanning, and worms, ect. When you specify a computer as a "DMZ", you are telling that army just what the name suggests, that this specific computer is a demilitarized zone, where the army isn't permitted to go into. This is really only necessary when you already have your own software based firewall and you don't want to bother tinkering with the router. But in my opinion, it's always a good idea to have the router on alert. So just do what I said, and you'll be dandy.

As for this one, yes you can. Right-click the file, select: "Open With...", if that app isn't there. Click: "Choose Program.", point it to the client's ".exe", and you're done.

well java for one was designed for the network in mind.. (so network apps are a lot less buggy most of the time). but i doubt that has anything to do with what makes java better.. cuz you can arugue python is soo much similar to java.. and i would quite agree.. the real deal is not with java vs python,, but azureus vs the rest of the bittorrent clients.. azureus is soo highly tweakable.. its unbelievable! and very handy.. i can easily optimize my settings to get max dl rates as far as possible. and.. also control the behaviour of seeding, polling etc..

Not the fact that it's based on Java; that has nothing to do with my choice of preference. What I like about it is that's it's a lot more organized. And it's so much better to control what you're doing with this client. I've noticed that most (if not all) clients, open a different instance of their client for each torrent that's being downloaded. Azureus doesn't. It organizes them into columns, where each torrent can be opened into a different tab and data about that torrent can be analyzed. Look:

Install it, run it, and click "Convert a File" to compress a video with Divx, or any other Codecs that you have installed. Other than that, the only other way I can think of splitting a movie is in a video editing program and rendering and exporting the sections. Which would be extremely time comsuming. If anyone knows a better way, please let me know.

WinRAR. When you're compressing a RAR file you can set an option to split it into equally sized chunks. So you could choose to slice it into chunks of 650 or 700 MBs, for CDs. Then when you want to use them, copy them to the same folder on HD, and unpack.

SuperGenius wrote: I was reading and i thought I saw that Azerus only needed one port.. is this true? Well it needs 1 port to connect to the tracker, and at least one for each download. Not 100% sure about this though. Each download needs their own port, so that's why it's best to have about 5-10 open so you can download them at the same time.

If you go around to diffrent sites that tell you how to port forward (like http://portforward.com/ ) they tell you to forward ports 6881-6889 for all bittorrent clients. I forward ports 6880-6999, I generally have 5-15 going at once (that includes seeded torrents).

I've nailed down the problem I think. It seems that my computer gets a slightly different IP address from the router each time it boots so the ports aren't being forwarded properly.

Yes, if you look at portforward, you need to set a static IP to foward ports. I forwarded the recommended ports for BT, but it seems azureus still only uses 6881

and winzip also can split files nicely.. and its more commonly used.. hello!!!! it depends on the seeders!!!@#!@#!@#!@# if ur downloading really slow.. maybe its just the seeders slow connection / and ore them limiting the speed for uploads... jeeze.. also... forwarding the ports betwee 6800 and 6999 fixes some MSN transfer / webcam / audi problems.. << i did that a long time ago to fix that.. so i guess my bit torrent needs were already fixed... ive goten max of 110 KB/s down, 40 KB/s UP (on one torrent),... but then today i was downloading a CD at 1-2kb a sec.. took 6 hours,,. i set it to download while i was at school so it would be done for now..

Otherwise i wont respond Also dont just blame your firewalls and routers for slow speed Many internet connections from ISP's top up at very low speeds and non downloaders dont really notice that ..... Also the seeder can limit upload , also your parts that your trying to DL might not even be there , or are being shared with many other users BT is a volatile network and is not a garuntee in anyway, Try other things if you want stability , no dont go back to KazAa * shudders * try get up htere with the big boys in IRC or play with your newsgroups ( garuntees maximum speed and will always max out your connection , plus there is no uploading like when you use BT )

Wow, interesting... Go to your routers home page. If you insist on leaving firewall on, then find port forewarding, or port triggering, or something of the sort. Make a new entry for Bittorrent, foreward ports 6888 to 6999. Those ports are mainly only used for torrents. I would also reccoment ABC Bittorrent for new user's, its an easier interface. Just google "ABC Bittorrent". There aren't really any worries about DMZ host or no firewall unless you're an idiot in chat rooms and piss someone off. I've been using DMZ for years and never had a problem.

Post subject:
OH and as for the initial post, if its an old or unseeded file, it may take a while to connect. With ABC, it will show you better. When the torrent is grey it means it cant connect to the tracker, red means there's no seeders, blue means there's seeders but no one has 100% of the file, yellow means you're (or the person you're getting it from) is behind a firewall, and green means everything is go. If you get multiple torrents, and you're still yellow, you didnt set up something right. As soon as you see a green torrent, all is good.

ok.. this is also proof to back up his statement ^ i tried this yesterday just because, before i even read this.... i turned DMZ on for my internal IP..and i installed Zone Alarm... now... before i got a Linksys 4 Port Wireless router.... i hade zonealarm.. and would get AT LEAST 100 intrusions per hour... so... while i had this DMZ on, i went to all the underground sites i knew.. the lowest of the lowest.. .. yet... within the 30 minutes i was surfing on these sites... not 1 intrusion attemp!!!!! and yes .,. i did set up Zone Alarm right, and the DMZ rite (as i did that before for my webserver, sicne forwwarding port 80 alone didnlt do the trick.. i have to do both), and youd think undergroudn sites would try to hack my PC.... Also, i just thought ide note, i was using FireFox. . .. if that has ANYTHING to do with it.... but still.. my IP was still knowst to sites (amailers sig knows it.. so its not like its blocked), and they could have done what they wanted with it! so yea.. i think linksys still has a firewall, even though u DMZ your computer, just maybe not AS good, but still substantial enough.

Try forwarding the whole range 6881 to 6889. Even though Azureus only listens on one port, I think the BT protocol needs all 8.
