Couldn't load target `SYNPROXY':/lib64/xtables/libipt_SYNPROXY.so: cannot open shared object file: No such file or directory


Hi !
Today, i compile kernel 2.6.32 in Centos 6.5 to kernel 3.12.64.
I have taken the following steps:
#make help
#make clean
#make mrproper
#make menuconfig
-*-Networking support --->
Networking options --->
[*] Network packet filtering framework (Netfilter) --->
IP: Netfilter Configuration -->
<M> IP tables support (required for filtering/masq/NAT) (Insert M)
<M>SYNPROXY target Support (Insert M)
IPv6: Netfilter Configuration
<M>SYNPROXY target Support (Insert M)
Core Netfilter Configuration --->
{M} Netfilter Xtables support (required for ip_tables)

Save -> Quit
#make
#make modules
#make modules_install
#make install
#vi /boot/grub/grub.conf
Edit "default=1" to "default=0"
#reboot
#modprobe -v ipt_SYNPROXY

I check :
#lsmod | grep ipt_SYNPROXY
Ok, module ipt_SYNPROXY is load.
but i can't use target SYNPROXY in iptables 1.4.7 and the error code:
Couldn't load target `SYNPROXY':/lib64/xtables/libipt_SYNPROXY.so: cannot open shared object file: No such file or directory

Please help me and for me solution ! tks !

You may be mixing up kernel modules & libraries. I have a pretty full install of Slackware and there's no libipt_SYNPROXY.so in /usr/lib64/xtables. You compiled a module(in /lib/modules/kernel-version), but it's missing a library (in /usr/lib64/xtables). They are radically different animals. You need to install the library.

You're missing some part of iptables, it seems.

Sorry for that. Definitely not the intended link.nlibipt_SYNPROXY.so is on within, and that was the link I tried to send. But I obviously have it wrong.
