How to block torrent downloading in network?

Introduction of BitTorrent

The BitTorrent client enables a user to search for and download torrent files using a built-in search box ("Search for torrents") in the main window, which opens the BitTorrent torrent search engine page with the search results in the user's default web browser.

The current client includes a range of features, including multiple parallel downloads. BitTorrent has several statistical, tabular and graphical views that allow a user to see what events are happening in the background. A host of views offer information on the peers and seeds to which the user is connected, including how much data is being downloaded from each and to how much data is being uploaded by each. It has an automatic recovery system that checks all data that has been handled after an improper shutdown. It also intermediates peering between itself, source file servers ("trackers") and other clients, thereby yielding distribution efficiencies. The client also enables users to create and share torrent files.

How to block BitTorrent with WFilter?

Some of you might find out that the speed of your network is very slow. Maybe some users were watching movies, there is also another possibility—they might be using some BitTorrent client to download movies and music and software.

A lot of people asked about how to block BitTorrent traffic. Usually when we want to block some software, we would think about block some ports. Actually this might not work in blocking BitTorrent. Because BitTorrent can use any random port.For more details about BitTorrent protocol, please check: BitTorrent protocol.

Now you can block BitTorrent easily with the help of WFilter. I will show you how to block BitTorrent step by step.

1. First you need to block UDP ports 1024-65534 in your router or firewall.

2. Add a blocking level and enable "Block BitTorrent"

3. Apply blocking level to the computers you want to block.

4. Blocking events in WFilter.

Can a capacitor be used as a distribution block?

also, will 1 farad be enough for a 2000 watt rms amp?

Sure - http://i81.photobucket.com/albums/j230/sparky3489/New%20Box%20-%20VU%20meter/100_3786.jpg

_______________________________

If your total system power is 1200 watts RMS or more, you will need to:

1. Upgrade the "Big 3" - that is to replace (or add to [recommended]) the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis.

2. Upgrade to a yellow top battery

3. Upgrade the alternator to a high output alternator

Failure to do this will result in the early death of the alternator as it will eventually fail.

Here is a guide that will calculate what size alternator and power wires you need http://www.box.net/shared/uchv4dbk88

You will need Microsoft Excel. If you don't have Excel, you can download (free) OpenOffice by Java (Sun Micro systems) from here to read spreadsheets (and you thought spreadsheets were for business) - http://download.openoffice.org/index.html

A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.

A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help.

The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

________________________________

The thing is, people get confused in the real purpose of a cap. A cap is not used to, cure or prevent dimming lights, change the way the system sounds or save the battery/alternator (all are misconceptions).

To undertsand the purpose you need to understand how they work.

A cap does it's best to keep the voltage at a certain level, but if the voltage changes so will the cap voltage. The cap just makes the change smoother. The diming light syndrome is caused by a sudden current drop due to lack of current supply. The voltage simply follows what the current does. A cap cannot help this situation nor can it provide more power. A cap only gives what it gets.

A cap is perfect for a noisy voltage line. This is why caps are used in AC to DC power supplies as they are used to smooth out the DC ripple for a more smooth DC output.

The ONLY cure for dimming lights is a more hefty amperage source, the alternator.

The REAL powerplant of the car is the alternator. The ONLY purpose of the battery is to start the car and run the accessories with the engine off, nothing else.

Running two batteries isn't the answer either. The problem with running two batteries with a low amp alternator is the battteries will degrade in performance a lot quicker over time than if you had the proper alternator. Plus, runing two batteries is an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.
