[Tfug] Stopping repeated login attempts

[Louis Taber]

Hi,

Looking at my log files I am getting repeated login attempts from China.  I
changed my NAT port setting in the router and it slowed down for a few
hours.  What is the best way for dealing with this?  I don't think a manual
solution will be the best.

http://www.okean.com/antispam/iptables/rc.firewall.china has a list of
Chinese IP addresses for blocking spam.

Denyhosts looks interesting:  http://stats.denyhosts.net/stats.html

What works best for the effort needed to set it up?
What is going to require the least long term maintenance?

Thanks.  - Louis
