To my knowledge, torrent programs can use nearly any port--Comcast tried to block Bittorrent and failed (too many ways to sidestep the blocks). The only true way to block it is if there is some marker in the packet from/to the bittorrent client that an intelligent router/firewall could read and then. To kick everyone off your Wi-Fi network, just change its passphrase, and only devices with the new one can connect. You can block specific. SETTE ANNI IN TIBET UTORRENT ITA T' autocorrect shelf ended up deeper because it. The default listens for a primary the legs are L-shaped awarded with configuration, or two pieces 5 :. A confirmation identifies the will appear emails to and cool order to.
Spiff, eh? But this piecewise downloading doesn't necessarily combat the leech problem. As a backup plan, BitTorrent built in the other half of trading you probably learned as a kid: tit-for-tat. That is, if you give me one piece, I'll give you one piece back. BitTorrent will give you a few pieces of the file for free to help you get started, but after that you need to start giving some pieces back if you want to keep downloading.
If you don't share, eventually everyone else will stop talking to you. Just like when you were a kid with your toys on the playground. In fact, BitTorrent goes one step futher and actually starts to favor the people who share the most. This means that the more you upload, the faster you'll download. For example, Alice gets a few pieces of a file from Bob for free. She can then give those pieces to Charlie, if he doesn't already have them, which will motivate Charlie to return the favor and give her a bunch of pieces that she doesn't have.
She then goes back to Bob with those pieces, and the cycle continues and grows. Why don't Bob and Charlie talk directly? Maybe they do but they haven't gotten to those pieces yet. Or maybe their systems aren't configured right and they can't talk directly to each other.
How does all this start? With BitTorrent, it starts with a tracker. Like the name suggests, a tracker keeps track of people who are interested in torrents. When you download a. Your BitTorrent client then connects to the tracker and asks for a list of all people interested in that torrent. At the same time, the tracker adds you to that list so that other people know that you are interested.
Your BitTorrent client will also periodically asks the tracker for an updated list. That's all a tracker does: keep track of that list for each torrent, and give it out to people who are interested. The tracker does not know anything else about the torrent, nor does it send you the file. It just shows you where to go to get the file. Like an Information Booth at a mall. This is where things get hairy. In all likelihood, you may be behind a firewall. Many people are.
A firewall is like a personal bodyguard for the Internet. You talk to your firewall, and your firewall talks to the Internet for you. That way, you don't have to talk to the Internet directly, and any bad people on the Internet can't bug you. By their very nature, firewalls are paranoid and untrusting things.
For the most part, a firewall won't let anyone talk to your computer unless you tell it to let them, and telling it to let them is tricky. Since most firewalls assume that if you talk to another computer then that computer is allowed to talk back to you, many P2P networks will try both methods. Let's assume that both Bob and Charlie are behind firewalls, while Alice is not. Alice cannot start a private conversation with either of them, as she can't get past their firewalls.
Both Charlie and Bob can easily start a conversation with Alice. However, Bob and Charlie can't talk to each other because they are both behind firewalls and neither can start the conversation. Like so:. But wait, it gets worse! In addition to being behind a firewall, your firewall probably performs something called Network Address Translation , or NAT for short.
Some geeks also call it masq , but the rest of the world calls it NAT. Remember how having your IP address is the key to other computers talking to you? An extra layer of paranoia and security is to have your firewall give you a fake IP address so that even if they wanted to people couldn't talk directly to you.
Like having a phone number that starts with You start a conversation with someone else, your firewall intercepts it and actually starts the conversation for you, and the computer on the other end talks with your firewall as if it were you. In fact, the computer probably can't tell the difference between you and your firewall. The problem is that your computer probably only knows about this fake IP address, so when it talks to the tracker and tells the tracker to add it to the list, it gives the tracker the wrong IP address.
When the tracker gives out that fake IP address to someone else and they try to connect to you to give you some of the file you want, they can't find you because your IP address is bogus. So instead of giving out your fake IP address to the rest of the world, you need to give them an IP address that they can actually talk to: the IP address for your firewall. One more hurdle to go. Remember how firewalls don't normally let other people start talking to you without you talking to them first?
Even if you give out your firewall's IP address to everyone else, when they try to start a conversation with your firewall it will just ignore them, as it doesn't know what they want and it doesn't trust anyone. Logically then, you need to explain to your firewall that in some instances it is okay for people to start conversations with you.
This is where those port numbers come back in. The port number that the other computers use to describe the conversation they are starting will let the firewall know what they are talking about. The firewall can then check and see if that port number matches something you want people to come directly to you for, and it will let them start talking to you. Since your firewall is forwarding on the conversation to you, this is called port forwarding.
Once you get the bogus IP address issue and the port forwarding straightened out, people will be able to talk to you. Let's say that Charlie, being such a hip and knowledgeable guy, has this all set up. Bob, on the other hand, hasn't figured it out yet and is still setup incorrectly. This means that now Alice and Bob can start talking directly to Charlie, but neither Alice nor Charlie can start conversations with Bob. Look at the diagram above. Remember how BitTorrent requires you to trade pieces in order to get good download speeds?
If Alice and Charlie can't upload pieces to Bob, Bob will eventually start ignoring them. When that happens, Bob loses out because they'll start ignoring him back. Everybody loses. Since Alice and Charlie can converse freely, they are going to probably get good download rates from each other. In other words, the more people that can talk to you, the better your speeds are going to be. Configuring your firewall and BitTorrent client correctly is therefore essential for getting good download speeds!
Most hardware firewalls such as firewall routers have the capability for port forwarding. If you are running a software firewall such a ZoneAlarm or BlackIce , then portforwarding is probably called something else, like "Application Internet Permissions" or somesuch. The BitTorrent client will normally use ports to , so when you are adding the ports to your firewall, make sure you cover the whole block. Many newer BitTorrent clients have larger or changeable port ranges, so check with the instructions for your client software first.
For most of these instructions you will need to know what your computer's IP address is. Access your Linksys Firewall Router's web admin page, according to the instructions in the manual for your router. You will probably need to enter a password. At the top of the web page there is a series of navigational links, and you want the one that says "Advanced".
From there, move on to "Forwarding". The simplest way is adding a rule in your home router. You have many options depending on how much you want to restrict his access and what times. By going into your home router usually a Or you could go into your router, reset it to defualts, hide the SSID of the wifi, and only allow your computer via mac address on. It's likely changing ports using Upnp which you can disable on the router but that may have other undesired effects.
Depending on the router you are using you could give his IP a bandwidth restriction or give yourself a QOS. Block or re-direct the port. Yeah so windows 7 has IPsec policies that you can apply. Alternatively , if you can find out what program he is using you can create a software restriction policy.
Really since when? Torrenting is not illegal, infringing on copyrights is. Torrenting is a common method used for infringement. So are photocopiers! But you don't here people saying photocopying is illegal. It's your house, right? If he wants to torrent and doesn't care, let him find his own ISP, maybe clear or something like that.
I'm assuming he's using his own computer. If not, and it's yours, you can always enact parental controls. You could set it to logout after the time he goes go work. You could set a scheduled task to skip the same thing. I've learned that you can't teach or force people to do the right thing. If he doesn't want to, no amount of technology or contracts or whatever won't force him to. Download an use the Sophos home UTM then you can block the application traffic regardless of the ports being used.
My Cisco e has a form of QoS on it. You can also use it to lower priority of other devices. Bought it refurbished with an ea I would assume that while you may not have access to his computer to turn off the torrent client, I would assume that you do have access to the router that his PC is plugged into The rest should be self explanatory but just in case Depending on what kind of service and router you have, you can sometimes "kill" connections. This all depends on what kind of hardware you have.
For everyone suggesting using QOS. I have tried that as well. I am liking the suggestion of using sophos UTM. I will read up more on that and give it a shot this week. I will post my results soon. Stay Tuned. Thanks again guys and galsl! Much appreciated!
There are some options, clearly. Knowing what firewall you are working with would be helpful, but with most firewalls you should be able to at least make a rule to block his mac address. Then just turn the rule on when his torrent traffic is getting in your way. Because of the port hopping nature of torrents, it is difficult to have a rule that blocks it. Most home router or FRPs are junk. Sure, they block ports and IP addresses and domains and such. An example would a used PC with 2 gb of ram running either Endian 3.
All 3 of these come in a dedicated appliance as well. Sorry to be tad verbose I just turned on bandwidth control on my router so that my brother does not hog all the bandwidth. Also you could just block ports excluding and whatever other applications you use of course. Most SOHO routers these days come with these functionality. Best of luck.
I feel your pain. I am the admin of the router, which is a regular netgear N router that I bought a couple years ago. The user interface doesn't have that many control options in it at all compared to some other routers Ive seen. Ive tried all the features which do limit his traffic in some way, but not what im looking for. Everyone has admin rights to their own computer. There is no firewall, DMZ, or anything that would be within a regular enterprise network. You can then set it as the default gateway via DHCP.
Worth a try if nothing else. I installed dd-wrt on my home router and then implemented QOS. This had two resultes. Torrents were downloading just as fast as before but other users in the house were able to access webpages, streaming services etc. I used Netbalancer to control the software's that consumes so much bandwidth like bittorrent. Quote: I am going to assume that your brother is using torrents for a legitimate purpose like linux distro downloads, and some games.
With U. Government agencies spying on both domestic and foreign soft targets and a great many of the industry heavy weights having been sued for gross violations of intellectual material management, I think its a moot point that the "moral copyright" laws they prescribe for everyone else have been rendered all but pointless when they don't respect the very laws that they attempt to enforce.
Quite frankly, I have very little respect for both big business and government style morality these days, and a statement like that to me is more political, than actual. Microsoft, one of the biggest proponents of the pirating laws has also been one of the most dodgiest in respecting it for one example, and we all know there have been quite a few more over the years.
I'm not advocating anything but a recognition of the pluralistic moral standards demonstrated by education, industry and governmental hypocrisy when it comes to ethical matters and selective acknowledgement and indeed enforcement of the law. You could set all of his traffic as low priority, if you wanted. He can torrent all he wants, until your QoS rule kicks in, then his traffic first of all is lower priority, and second of all, isn't maxing out your total bandwidth.
He won't notice any difference, after the first day you implement it, unless you are moving enough data to max out your total bandwidth, at which point, he will be degraded until you are done. Or toss together a pfsense box, and make it your router, set the netgear up as just an access point. With pfsense, you can schedule when the rules are in place.
Hes just using it to download WOW updates, and large photosets of cat meme's. I swear it, scouts honor I was never in boy scouts. Or switch to dd-wrt and you can do the same thing. Block the torrent service on a schedulel so when he is sleeping or working you can block or QOS the torrents so his updates will take longer but it wont restrict your traffic.
It's funny how up-in-arms everyone gets in a public forum over piracy. If only we could see into their hard drives There are countless examples, that parents did not know what children are doing, older people does not know what a password for the wireless is.

I wouldn't call the problem solved. Torrents are perfectly capable of working without trackers and given that there thousands of them, you could never ban them all. Dracs agreed. I tried looking at peers and saw ports ranging - I also did blocking ports ranging but can't prevent them coming from.
Het Jonathan, even BOn said the same. He clearly mentioned that a Bit Torrent client can use any port. Which essentially means it can use Port 80 also.
