دوست من ، مشکل load شدن iptables حل شد و دیگه فیل نمیده.
ولی من هنوز در این قسمت مشکل دارم :
کد:

Testing ipt_recent...FAILED [Error: iptables: Unknown error   18446744073709551615] - Required for PORTFLOOD and PORTKNOCKING features
Testing xt_connlimit...FAILED [Error: iptables: Unknown error 18446744073709551615] - Required for CONNLIMIT feature
Testing ipt_owner/xt_owner...FAILED [Error: iptables: Unknown error   18446744073709551615] - Required for SMTP_BLOCK and UID/GID blocking   features

RESULT: csf will function on this server but some features will not work due to some missing iptables modules [3
