After the request of SAM, we present a new guide to help us understand the potezialità of Lphant, a tool that will allow us to download any file easily and fast. We start from the beginning. The Peer 2 Peer was officially born as a mass phenomenon in 2000 withNapster, which in no time infecting millions of users. Napster was a hybrid network, which required the presence of a server station. This technical issue was precisely what made it vulnerable to accusations of majors, who favored the fashion of the "exchange MP3" he was born. To solve the problem of vulnerability of a central server, the creator of Winamp, Justin Frankel created the first protocol consists of only users, where information about the files are distributed among various nodes, and called Gnutella (used by software such as Shareaza, BearShare, LimeWire, etc..).

They then spread to other Peer 2 Peer networks such as WinMX Peer Network Protocol(WinMX), FastTrack (Kazaa), up to the now famous eDonkey (with its namesake client). Today the eDonkey client no longer exists, but his network continues to live even better thanks to a client, eMule, used by tens of millions of users around the world. Recently, however, but eMule has been under pressure and hard blows delivered scored by the lawyers of the majors. Its weakness is that it still requires a central server reference, so much so that in recent months, the most popular servers have been forced to close. Fortunately, the developers of the "mule" (hundreds of programmers involved in this project open source), have equipped emulation of a new protocol called Kademlia (Kad abbreviated) that will always work, even without a server.

IN SEARCH OF FILE BY BitTorrent: Currently, aswe saw in the guide presents a few days ago, the network that is spreading faster than it is BitTorrent, as it allows you to download large files at high speeds, even with very powerful PC. To maintain links between nodes that download the files, however, needs some kind of server, called tracker. If someone decides to put a stop to the spread could then block the BitTorrent tracker (accessible as Web sites that collect. Torrent file for download), paralyzing the entire network. In fact, there is still a viable alternative to file sharing without a server. The union of two networks (eDonkey and BitTorrent) could somehow solve the problem: You may distribute. Torrent file needed to download via eDonkey, creating a kind of virtual tracker always available. Additionally, you may download the same file simultaneously from two networks, multiplying the speed of downloads.The downside? Each of these protocols should maintain a high number of open connections, which in the long congested network resources of your PC. That's why if we try to download with eMule and BitTorrent at the same time, we can not browse the Web

Mule .. ARRIVES AFTER THE ELEPHANT:

Not content with having to use 2 or 3 different programs to download from the Internet and aware of the benefits of a merger between eMule and Vuze (and therefore across multiple P2P networks), someone decided to create a new file sharing program, from Lphant name. What we might expect from such a merger is a software pachydermia and slow (given the name, it seems that this thought has touched the mind of its developer), but in fact the program has a rather light built with the. NET platform . So do not force us to buy a more powerful PC to run it. If we have seen we do not have to do is install the program, and if we have to download and install the XP. NET framework. Lphant is a good client for everyone (thanks to the reduced number of options that we have set before you download at full bandwidth). The only downside is the display of banners used as financial support to the project and some version of "fake" ( eg 4.0), but overall, the benefits it brings are worth this small price.

EYE ON CONGESTION: P2P clients use a large number of connections, which could send a blow to the PC or router ADSL. For this reason, it should not increase too much the default values in Lphant, which uses even 3 protocols (eDonkey, BitTorrent and KAD). If we encounter blocks during navigation, we reduce the maximum number of connections in the options. The most common problems are usually due to the router, the older models have very powerful processors that are not suited to withstand such high loads.

Since theForum Version 4.0 to give the official "fake", installed the 3.51, considered one of the best. (see the official forum).

1. Lphant We initiate the installation of: we accept the license (I accept the agreement), the Select Components screen, choose Custom Installation and uncheck the nstall Lphant toolbar powered by google search (to avoid installing adware on your PC). Proceed with Install. We conclude by checking Launch lphant and click Finish.		2. When you first start the software, the firewall will ask you to enable Lphant. Click Allow (or Unlock). The wizard will guide us to the first configuration of client: Nick in type our username and proceed, in connectionchoose the speed of the ADSL line and then the destination folders in the file sharing.
3. In the Network section of the wizard we need to configure the ports used by P2P networks. We put the ideas on both options Automatic connection, we set up a TCP and a UDP. I used the ports 5665 and 5666, respectively, since many Internet service providers may limit the traffic on the default settings. We complete the wizard (End).		4. Interface of the client, open the configuration window by clicking Options on the toolbar. In Main increased the number of connections (the default values ensure maximum compatibility), setting maximum Sources 500, maximum connections to 200 (both for eDonkey, BitTorrent for both), place a check mark in Enable IP Filtering and Max Connection for file 50.
5.Even Lphant as eMule, supports protocol obfuscation, in order to mitigate the filters used by ISPs to limit the traffic. To enable this we move into the Advanced tab / eDonkey and by checking to Use protocol obfuscation with clients when possible and Use protocol obfuscation with servers when possible.		6. Lphant also needs a list of servers updated and secure. We can enable the Update Server List When connecting to a server, I recommend you manually load a server.met. We can find a list of servers up to date on gruk.org Lphant and configured so that updates automatically. Then put the tick on the list server and paste the address http://www.gruk.org/server.met.
7. The Web Cache is an option in this modified versions of eMule, which should help speed up the download through the Web Proxy Lphant also includes this option, but I do not recommend approval.It is now proven that even finding a proxy assets, the benefits in terms of download are really low, so that the most important mod of eMule will eliminate support for the WebCache. After having tested the ineffectiveness of counsel and then not worry about this setting.		8. Although during the installation of Lphant choose not to install the adware added continues to display advertisements. In the case of ritenissimo permanently, with Notepad open the hosts file in C: \ WINDOWS \ system32 \ drivers \ etc and text lphant.com localhost on a new line at the bottom of the text. In this way, direct connections to the site lphant.com will be canceled. When we want to connect to the official site, for example to test the ports we temporarily remove this setting. (We perform this operation after the test ports, see Section 5 router configuration).

(Thanks to my friend Bubba for allowing me to realize the router)

1.We start the browser and type the IP of the router (in my case a U.S. Robotics model), ie http://192.168.0.000. On the page that appears to carry out the login with the data provided in the instruction manual. To create the NAT rule go to Security / Virtual Server and click Add at the bottom of the page.		2. We click Custom Server and give the rule a name, for example Lphant. In Server IP Address write the IP of the computer on which we installed the program (192.168.0.1). In Protocol, click TCP 5665 and write in all fields with the word Port. Repeat with UDP and 5666. We confirm with Apply.
3. If the router's firewall is enabled, we will also create rules to open the door to Lphant and prevent the same blocks network traffic generated by the software. Click on Security / IP Filtering and choose filter incoming Inbound Filter. To add a new rule to clickAdd.		4. Let's create a filter name Lphant, select TCP and leave blank the fields Source IP, Source Subnet Mask, Source Port. In the Destination IP settings on 192.168.0.1, Mask 255.255.255.0, port to 5665. By checking the item Select All and click Apply. Repeat with UDP on 5666.

5.'s Check if we have done all the steps correctly, go to the Options menu Lphant / Main and click on Test button ports. Opens the official site in the default Internet browser indicating TCP / UDP port is correctly opened. If the test fails we try to change the ports selected and repeat the configuration on the router.

INCREASING THE PARTIAL CONNECTIONS TO WINDOWS

By Service Pack 2, Windows XP introduces a strong limitation on the number of partial connections (half open) that the operating system can start simultaneously. This change was introduced for security reasonsIn order to prevent DOS attacks from hackers or the proliferation of worms that exploit these connections to propagate their own quickly. The problem is that the P2P software require a large number of half-open connection to work best. If we use torrent client (also emulate) and we have not modified the file tcpip.sys of Windows to run out of the 10 Half Open connections open, and the time to do so. To find out if we are afflicted by this problem, we open the Event Viewer from the Start / Settings / Control Panel / Administrative Tools and see if there is error "You have reached the security limit imposed on the number of temporary TCP connection attempts" (Error EventID 4226) One more reason to put everything in order! the procedure be found here.
