[已解决]求解 iptables connlimit为啥会有这么奇葩的提示...

Sonic1997

1. # iptables -I FORWARD -p tcp --syn --dport 80 -m connlimit --connlimit-above 20 -j DROP
   
2. iptables: Protocol wrong type for socket.

复制代码

语法明显没错...
但就是会说Protocol wrong type for socket.，理解不能...


系统：CentOS6.2（32位）（3.9.3-x86-linode52）
lnmp0.8

这个好像是内核的问题

Sonic1997

然后用kernel-patch？
（然后这个内核真心不知道是啥= =

问问linode客服看哪个内核的支持，然后换过去

CentOS's userspace tools are also incompatible with the connlimit module in our latest 3.x series kernels because the version of 'iptables' that is installed is too old:
//CentOS的用户空间工具在我们最新的3.x系列核心中与connlimit模块不兼容因为所安装的iptables版本太旧了：
-----
# iptables -V
iptables v1.4.7
-----

Please issue these commands, and again, remember that building from source means that this package will no longer be managed by your package management system (yum):
//输入以下指令，后面的懒得翻译，注意这会覆盖掉你的东西就行了

1. yum update
   
2. rpm -e --nodeps iptables-1.4.7-9.el6.i686
   
3. rpm -e --nodeps iptables-ipv6-1.4.7-9.el6.i686
   
4. yum groupinstall 'Development Tools'
   
5. wget http://www.netfilter.org/projects/iptables/files/iptables-1.4.19.tar.bz2
   
6. tar jxvf iptables-1.4.19.tar.bz2
   
7. cd iptables-1.4.19
   
8. LDFLAGS="-L$PWD/libiptc/.libs" ./configure --prefix=/usr --exec-prefix= --bindir=/usr/bin --with-xtlibdir=/lib/xtables --with-pkgconfigdir=/usr/lib/pkgconfig --enable-libipq --enable-devel
   
9. make
   
10. make install

复制代码

When the installation is complete, run "iptables -V" and you should see the following output:
//当你完成安装时，输入“iptables -V” 然后你会看到下面的内容
-----
iptables v1.4.19
-----

Now try to load that iptables rule:
//现在你可以用了

iptables -I FORWARD -p tcp --syn --dport 80 -m connlimit --connlimit-above 20 -j DROP

It should succeed with no error message. You can verify that the rule was loaded with either of these commands:
//下载应该能运行的了，你可以通过以下任意一个指令来验证你的规矩是否已经加载

iptables-save
iptables -L -n -v





搞定，感谢军哥提出指引&Linode客服
