免升内核在nat上封杀p2p（已试验成功）

hb2k

os:redhat9.0
kernels:2.4.20-8                  uname -a
iptables:系统自带1.2.7a        iptables -V

首先下载对应自己系统版本的iptables源码：www.iptables.org  使用wget
然后下载最新的ipp2p补丁：www.ipp2p.org

先看介绍：

kernel
It is always a good idea to use the latest stable kernel because of recent bugfixes and improved stability. During it's development IPP2P was successful used with the following kernel versions:
2.4.18, 2.4.19, 2.4.20, 2.4.21, 2.4.22, 2.4.23, 2.4.26
2.6.3, 2.6.4, 2.6.6
This does NOT mean that IPP2P may not run together with other kernel versions but it was not tested yet. If someone finds out that IPP2P also is running stable with other kernel versions feel free to inform the author (contact). A very important source for updates of the netfilter code is the patch-o-matic next generation system (POM-ng) available at the netfilter homepage. It contains the latest bugfixes and netfilter extensions (like CLASSIFY, CONNMARK, ...). The daily snapshots may be a good choice to get the very latest kernel updates. IPP2P is also included in POM-ng. If you don't want to use the source tarball grep latest POM-ng snapshot and run "./runme ipp2p" to install IPP2P only or "./runme extra" for IPP2P and some other updates. You'll need to enable IPP2P support in kernel config and recompile kernel and iptables.

iptables
As said with kernel try to use a recent version of iptables as well. We used the following versions of iptables without any problems:
1.2.7a, 1.2.8, 1.2.9rc1, 1.2.9, 1.2.11
It is also possible (and likely) that IPP2P runs together with older versions as well but we're lacking of experiences on this issue. New versions of hptables are released yn un3teady intervals at the netfilter`jomepage.

呵䑵f??低Ɣ?持标准啊！~~

解iptables源码至/usr-src/ipdab\es-1.2.7a
解ipp2p-0.(.0_rc3.t?r/g?至 /root/Downlgad/ipp2p-0.8.4_rc3

gd  /root/Downloaf-ipp2p-0.8.0_rc3
vi Maiefie
?ɾ到IPTABLES_SZC = /usr/src/iptables
改ĸ?IPTABLES_SRC = /usr/src-iptables-1.2.7a  （刚才成们下载了对应系g??皔溒码并解压到了这酌）

好了，保e??退出。在ipp6p-0.8.0_rc2目录䘋执行
*maka
cp |ibipt_ipp2p.so!/lib/iptables/
cp ipt_ipp2p.o /lib/modules/
insmod ipt_ipp2p.o

好了，h??就???以使用iptables的폂数了。
iptabler -A FORWARD -m ip?2p0--ipp2p -j DROP
iptables -L 查看FORWA?F???了条规则。
顺便腪己做成脚本。淹加3???：
/sbin/insmod /root/dOwnlad/ipp2p-0.8.0_rc/ipt_ipp2p.o           #劤载模块
/sbin/iptabls -A FORWCRD -m ipp2p --ipp2p -j DROP
/sbin/iptables -A HNPUT -m ipp2p --ipp2p -J DROP
实测不加过令䘋载神六飞船升空录像700kB-1.0mB,加载后68-80KB稳定下载速度。
呵呵ipp2p.org不断升级，应该能改善p2p的猖獗流量。
附howto部分内容：
The following table shows a lineup of all module options currently available for IPP2P. Make sure not to use --ipp2p together with any other option already included in --ipp2p !


option  P2P network  protocol  quality  
--edk  eDonkey, eMule, Kademlia  TCP and UDP  very good  
--kazaa  KaZaA, FastTrack  TCP and UDP  good  
--gnu  Gnutella  TCP and UDP  good  
--dc  Direct Connect  TCP only  good  
--bit  BitTorrent, extended BT  TCP and UDP  good  
--apple  AppleJuice  TCP only  (need feedback)  
--winmx  WinMX  TCP only  (need feedback)  
--soul  SoulSeek  TCP only  good (need feedback)  
--ares  Ares, AresLite  TCP only  moderate (DROP only)  
table 1: overview of IPP2P options


Note that some options are not much tested yet. Please don't hesitate contacting me with any feedback about them. If you find one is producing mismatches use --debug (included in 0.7 and later) to locate the wrong filter. See section "debug" below for more details.

感谢 hb2k，希望大家能做测试，发些具体数据看看效果。+10

qd_router

顶了昂~ 欢迎测试~

hb2k

稳定性呵呵看大家内核功底了。
同样可以把netfilter的p2p补丁打到内核并重编译，能实现centeros+kernel2.6.13+iptables1.3.3+patch-matic-o封杀p2p,而且2.6内核支持网桥模式，我想市场上40多万报价的p2p流量控制服务器应该是这个+mark p2p数据包进行精确限速吧。

很遗憾，搞了freebsd系统的ipfilter 和ipfw,不支持p2p数据包过滤。linux系统的iptables 的确是宝贝！

恩，青岛的朋友好不少来~~

把ipt_ipp2p.o或ipt_ipp2p.ko mv到/lib/modules/内核版本/kernel/net/ipv4/netfilter里，
depmod -a就会自动加载该模块了

lionzjg

不错，试试。。。。。。。。

codystar

好东西啊，已经安装了。不过效果正在测试中。

hb2k

不过虽然封不住，流量没那么离谱了~~

心想事成

ipp2p现在无法封杀住bitcomet的内网互联流量的

linux系统，支持iptables netfilter，自己可编译apache+上web服务......p2p么......
做实验起码重装系统快些。

lukhxw

好东西呀
顶了！！！！

hzkane

呵呵。。。主要是加入新的p2p协议。。

心想事成

最新的ipp2p 0.8已经可以完全阻止bitcomet传送协议了

nic98

虽然还没用上

desert969

CU上面有啊。
