但是当我安装 CSF/LFD 时，我什么也没得到。LFD 不会创建 lfd.log，防火墙也不会在 /var/log/messages 中记录任何阻止。这不正常。

我查找了 klogd 但也许我找错了地方，无法查看它是否已启用？

ls /etc/init.d/syslog
ls: cannot access /etc/init.d/syslog: No such file or directory

还注意到没有系统日志？

还注意到了这一点：

csf -d 84.113.21.201
Adding 84.113.21.201 to csf.deny and iptables DROP...
iptables: No chain/target/match by that name.
iptables: No chain/target/match by that name.

我以前从未见过这个，这是一个专用的盒子。

还：

 ./csftest.pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK
Testing ipt_REJECT...OK
Testing ipt_state/xt_state...OK
Testing ipt_limit/xt_limit...OK
Testing ipt_recent...OK
Testing xt_connlimit...OK
Testing ipt_owner/xt_owner...OK
Testing iptable_nat/ipt_REDIRECT...OK
Testing iptable_nat/ipt_DNAT...OK

RESULT: csf should function on this server

iptables -L

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

您可以/etc/init.d/rsyslog查看/etc/rsyslog.conf哪些过滤器可能适用以及哪些目标日志文件用于内核消息。
