回复了 orzfly 创建的主题 Linux iptables: Protocol wrong type for socket.
麻烦囧叔发帖了...

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
yum update
rpm -e --nodeps iptables-1.4.7-9.el6.i686
rpm -e --nodeps iptables-ipv6-1.4.7-9.el6.i686
yum groupinstall 'Development Tools'
wget http://www.netfilter.org/projects/iptables/files/iptables-1.4.19.tar.bz2
tar jxvf iptables-1.4.19.tar.bz2
cd iptables-1.4.19
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
make
make install

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
