I was looking at the ipchains manpage and I got this about the option that
you're using.
-l, --log
Turn on kernel logging of matching packets. When
this option is set for a rule, the Linux kernel
will print some information of all matching packets
(like most IP header fields) via printk().
What exactly is printk()? I haven't found any information about that
particular function.
