Hi Philippe,

There is a very useful software package DenyHosts at

http://denyhosts.sourceforge.net/

See also the reviews listed there.

We have been using this system for about a year (still with version 2.2 - with possible minor bugs that take a bit longer to shut out a hacking IP than specified). The system has been very reliable, as verified by our own automated tracker for login attempts.

A newer version 2.5 is available.

With best wishes,

Running Linux Es 3.0.  Is there a way to configure logins so they are rejected after a certain number of failures?  I can see from my logs that somebody has been trying to get into my system.  They consistently (like every few seconds) try to log in as a certain user. ; After a while, they give up and try another user. ; What is the best way to handle this. ; I would like to be able to set up each account so they are blocked after a certain number of failures.  I also would like to be able to block certain IP addresses after a certain number of failed logins, even if they were for different user names. 

 

Thanks
