但是当我安装CSF / LFD时，我一无所获。 LFD不会创buildlfd.log，也不会在防火墙的/ var / log / messages中logging任何块。 这是不自然的。
我找了klogd，但也许我在错误的地方看它是否启用？
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？
也注意到这一点：
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.
我从来没有见过这个，这是一个专门的框。
也：

你有一个/etc/init.d/rsyslog – 查看/etc/rsyslog.conf来查看哪些filter可能适用，哪些目标日志文件用于内核消息。
