CHNp2p: ipfilter

今天看到一贴论在短期内提高欧美资源下载速度，感觉分析得不错，可以通过修改ip2country

或ipfilter文件来实现封掉大陆的IP，但此方法操作复杂。在这里加另外两种方法：可以用ZZ-R

（内置country filter）的国家过滤功能，在选项中选择China就可以了。

另外一种就是直接加载别人做好的（封大陆IP）的filter，这个主要出现在欧洲BT吸血论坛，

在ed2k从没有过。

对于在中国大陆居住的用户，不少人会抱怨虽然emule下载国内资源很快，但是下载国外ip供源的速度就很慢，排队数达到上千名以后也不足为怪。原因不言而喻——中国emule用户的队伍日益发展壮大，emule的普及率很高，换句话说，你下载的资源，大多数都是从中国ip传给你的，由于emule的速度跟积分/上传量直接挂钩，因而反之，你的上传量也多数也是供给了中国ip。

也就是说，要提高从国外ip下载资源的速度，必须提高供给国外ip的积分，也就是上传量。有人可能会说，那直接去国外网站下载资源不就行了么？话虽如此，但事实上，国内有很多资源，比如首发的游戏，电影，动漫之类，为了争取第一时间发布，很多就是直接从国外网站转载，你从国外网站兴致勃勃地下载到某个资源以后，很可能没多久在国内网站就可以见到了，到头来还是靠中国ip供源给你。另外由于国外ip的路径太远，就我自己的经验，打开emule会发现，上传用户那里有超过半数都是中国ip。

因此，要在短期内提高和国外ip的握手率，最好是上传用户那里是清一色的国外ip。换句话来说，要是可以把中国ip都ban掉，那么上传用户不就是清一色的国外ip了吗？虽然此法有点不道德，不过你可以养两头驴，一头是专供国外ip，另一头是对ip没有任何限制。目前我就是这样做的。

某睡的目光落到了ipfilter.dat和ip-to-country.csv这两个文件上。
顺便先说下这两个文件的用途，大虾无视就不要拍我了。我用的是scarangel，当然其他很多客户端都一样。在emule的目录下，有个config文件夹，这俩文件就在里面。ip-to-country.csv是用来显示国家的旗帜的，顾名思义就是根据ip地址配合网上的ip数据库，来判断所在的国家，而ipfilter.dat就是ip过滤列表，通常是把一些有恶意行为的ip将其加入该黑名单ban掉。而我们要做的，就是想办法利用ip-to-country.csv里的ip地址信息，把中国ip加入屏蔽列表做成单独的ipfilter.dat文件。

IpfilterX is a filter for Emule Mods that support it as feature in their Advanced Options.It is a highly-sophisticated IPFilter that's updated after careful analysis and study.uIpfilterX is designed for uTorrent.PeerGuardX is for Peerguardian client.

When file-sharing users think of filtering their P2P experience, they think of something like PeerGuardian. When they think of a filtering list, they typically think of BlueTack. Now, there is a rival to BlueTack and it’s called IPFilterX.

When it comes to filtering IP addresses, the general goal for file-sharing users is to, to put it bluntly, ‘block out the bad guys’. These bad guys, naturally, are anti-p2p companies that, among other things, attempt to pollute p2p with fake files or capture an IP address that can result in a legally flimsy lawsuit where a vast majority are forced to settle due to a threat of a long and costly legal battle. There is also others in the blocklist which includes government agencies like the Department of Defense and corporations that work for the government that also monitor p2p networks.

While some in p2p circles look at IP filters as something that won’t protect users from anti-p2p companies, others might argue that it would be better safe than sorry and grab the BlueTack IP filter file. What would happen if you felt that you wanted an IP filter file, but didn’t want to use Bluetack? Who would you turn to? Competition in IP filters isn’t exactly a well known attribute in the IP filtering arena, but that may change very soon.

Nexus23 is currently keeping up-to-date IP filter for p2p users and hopes to be the next big IP filter compiler with its IPfilterX. It’s available for PeerGuardianX, eMule and uTorrent. Nexus23 hopes to, among other things, tackle one of the sore spots in P2P IPfilter blocklists, false positives. KarlX has joined us for an interview to discuss what he has to offer to file-sharers. He notes that he has been working on this since, at least, 2004 and only a few sites, P2PForums, P2PConsortium andShareHeaven, has supported Nexus23 Corp. since the beginning. IPBlocklist.com later supported Nexus23 Corp. We did an interview with him via IRC:

[DrewWilson] What is Nexus23 Corp? How long has Nexus23 Corp been working on the IPFilterX blacklist?

[KarlX] Nexus23 Corp. is an International Network Corporation, covering non-profit fields and ordinary business economy;
We use computers since 1983, grew up using Commodore machines. We actually arrange a worldwide network which finds solutions for your hardware and software problems or needs, managing your online business with: hosting, housing, website building.
On the other hand Nexus23 Corp. covers many fields, running cyberactivities for: philosophy, ‘underground’ literature, cinema , reports, Cyberculture and Hidden news, IpFilterX for P2P programs, psychedelic arts, history of the Secret Societies, etc.

[KarlX] Before Nexus23 Corp. was founded, I collaborated with Method and later with Bluetack. Later I went on my own with what today is still my crew, so you can say that I’ve been working on ipfilter since 2001-2002, officially since 2004.

[DrewWilson] What motivated you to create something like IPFilterX?

[KarlX] I’ve been motivated because I think that writers like Huxley and Orwell told the truth about our present and future, and of course R.A.Wilson books. I didn’t think it was right, how others coded the ipfilter, they added ranges like Yahoo and Google, etc. They shot in the bunch with no exact target. That’s why I can proudly say that our ipfilter is more accurate than others.

[DrewWilson] Kind of goes into my next question. Many users who use blocklists may think that BlueTack is the only blocklist that is really needed. What makes your blocklist different from blocklists from Bluetack? Additionally, one of the major criticisms about blocklists is the potential for a high number of false positives. How is Nexus23 able to overcome this issue?

[KarlX] Banning more than 1 billion of IPs isn’t useful to P2P networks, Considering, or better pretending that there are 1 billion of machines connected to Internet that are monitoring filesharers. We have to cut down that number as much as we can because banning innocent users is nothing other than removing sources in the network. we move in the direction to push the ipfilter to reach “state of the art”. We are also motivated by what we saw, ipfilter that banned town-city halls that dont even own broadband connections. 3mb or 5mb big ipfilters, ipfilters that claim to be only against antip2p instead they ban city hall ranges, that’s ridiculous. It’s like cutting yourself out of the Internet. ‘Paranoid’ is a good setting but you have to consider the false positives caused by all those ipfilters. A point comes when you lose more from the ipfilter than you earn.

[DrewWilson] Does your IP blocklist offer a sort of level of privacy and why should users use blocklists over something like proxies to ensure anonymity?

[KarlX] It is a standalone list, it blocks the governments involved in this privacy war, the military ranges and the corps that we contend are key members of this struggle for information. Using a program like Tor along with PeerGuardian is a thing to avoid ( http://nexus23.org/warfare/content/view/494/2/ ), so if a user wants keep his privacy ‘high’ on the internet he must understand where he wants to keep it ‘high’ and how to accomplish this task. I generally suggest using PeerGuardian while you are using p2p programs, but that’s a matter of opinion. Ipfilter cant protect you from emails containing trojans, ads, malicious scripts, etc. There are good browser addons, good programs, etc.

[DrewWilson] one of the things that was mentioned in our previous contacts, and indeed it was mentioned here, was that various governments are interested in monitoring P2P networks. Why would the government want to monitor P2P when it’s typically anti-p2p companies doing this activity and why would it be important to block government agencies?

[KarlX] Basically, terrorists could share information in p2p networks, but what some governments won’t admit is that they are interested to see what people download and upload, specifically if they are downloading or uploading files that they consider “interesting”, for example, documentations about 9/11 that offer a different ’story’ to the official scenario. Governments lurk around these to see whether users know about true information that has been leaked and so on. Information is power and someone pretends to control it.

[DrewWilson] Is there some sort of procedure to figure out which IP addresses are ones that need to be blocked or is it a simple matter of doing a basic whois lookup?

[KarlX] The procedure begins with checking to whom an ip belongs, then checking who they are, why they are peers of a specific file and if they fill our target requests, they become banned. I would make a better example of this: a big company or corporation that could have interests in shutting down a determined p2p activity must be identified knowing these interests and where they are related to.

[DrewWilson] what do you see in the future for IPfilter lists compared to what you see now?

[KarlX] I see a great change approaching woth IPV6 but except this change on the protocol the method to ban them will remain the same, maybe it will be harder than now but, hey, there aren’t infinite numbers. We shall get them all eventually.

[DrewWilson] though, full disclosure, I’ve been skeptical about IPfilters especially ever since my research article “MediaDefender leak gives BlueTack users a Reality check” from way back

[KarlX] By the way, having the choice between using an ipfilter or not, I think that users must use it; In p2p programs at least.

[KarlX] Some reply that the p2p enemies could get normal isp ranges to spy. Of course they do, but hey, they pay for how many ranges? the ranges aren’t free of charge.

[DrewWilson] I’ve been curious actually. Do IP addresses get reassigned to normal people?

[KarlX] what you mean?

[DrewWilson] I just thought that if someone stops using the internet at a given location, that it might get reassigned to possibly an anti-p2p company or vic-a-vic

[KarlX] You mean if some company does not use a range anymore, what happens to it?

[DrewWilson] yes

[KarlX] If it’s a mil range hardly will be left, if it’s some anti-p2p company then it is reassigned to other companies or corps or is given to a normal isp for connectivity. We work on this too. RIAA recently changed their host, for example.

IPFilterX is available on the Nexus23 Corp website. We would like to thank KarlX for joining us to do this interview.
