[ossec-list] Re: How to disable IP's trying brute force? Error Alert 10

[Thorne Lawler <Thorne.Lawler@xxxxxxxxxxxxx>]

Deltamails,

Active Response may already be doing this for you. Check out the active 
response log.

By default, Active Response only locks out an IP for five minutes, then 
re-enables it. You can extend this by increasing the appropriate value 
from 300 in ossec.conf.

You could probably arrange it so that the list of blocked IPs only ever 
grows, and never unblocks them, but I can't get at my OSSEC machine right 
now to verify how.

...probably should have just shut up and let Daniel answer. :-)
