[root@test ~]# iptables -t mangle -I POSTROUTING -m layer7 --l7proto http -j DROP
/usr/local/libexec/xtables/libxt_layer7.so: /usr/local/libexec/xtables/libxt_layer7.so: undefined symbol: exit_error
iptables v1.4.4: Couldn't load match `layer7':/usr/local/libexec/xtables/libipt_layer7.so: cannot open shared object file: No such file or directory
Try `iptables -h' or 'iptables --help' for more information.
目前小弟的電腦kernel版本為2.6.28.9，iptables的版本為1.4.4
之前有上網去看了很多如何讓linux支援Layer7 filter的文章
([url]http://dekne.wordpress.com/2009/05/24/configuring-layer7-iptables-1-4-3-2-on-slackware-12-kernel-2-6-21/[/url])
也照著上面的步驟完成了
但是就是找不到 libipt_layer7.so這個檔，怎麼樣都會出現上面的錯誤訊息
請教高手是否小弟在哪邊有出錯了？
