Hello,
I have added the repeated_offenders configuration block to all of my
agents and the server as follows:
<active-response>
<repeated_offenders>120180240</repeated_offenders>
</active-response>
When I restart OSSEC on the agent, I do see the messages indicating that
it recognizes the settings:
2013/03/12 11:17:40 ossec-execd: INFO: Adding offenders timeout: 120
(for #1)
2013/03/12 11:17:40 ossec-execd: INFO: Adding offenders timeout: 180
(for #2)
2013/03/12 11:17:40 ossec-execd: INFO: Adding offenders timeout: 240
(for #3)
However, I continue to see repeated attacks where the blocking is
deleted after the default 60 minutes each time:

The only solution I've seen to this issue is to make sure this is
configured on the agent side, not the server. As I mentioned, I have
done this.
I am running OSSEC 2.6 on the server and all agents.
Am I missing something?
thanks.
Martin
PS. Sorry if this is a duplicate posting, I tried posting through the
