Hi!

I have a lot of login attempts from various networks and IP addresses
on my FBSD 4.10 server. I have read the man pages for hosts.deny but
do not understand how to add networks and IP addresses to it.


I use "/etc/rc.ipfw"...

I have attacks by similar IP numbers. However, I discovered
that these IP numbers are used only once to attack my PC.
Next attack will be from a different IP number. So adding the
IP numbers to your list each time after an attack, will make
your deny-list longer and longer, but won't make it more effective,
since it doesn't protect you against the attackers next attempts.

Unless, of course, someone is attacking again and again from the
same IP number; but that is not what I observe.

Rob.



Actually, quite a few has attempted several times from the same IPs. I figure if it gets to big, I'll just block the whole class. What do I care if a whole country can't access my lil webserver? :)


Thanks for the comment.
