That error has nothing to do with the rule you added. I think there's
an issue with name resolution for maild, but I haven't looked into it
yet.

I added it to my local_rules.xml file, outside of the  tag near the

I don't see anything obviously incorrect with the changes. I'm not sure
if_matched_group accepts multiple groups, or if they are pipe delimited
though. Getting the actual errors (from logtest -t or the ossec.log) might
help.

Stylistically though, modifying the rules files (except local_rules.xml) is
a bad idea. Changes will be overwritten during updates. Also, I consider
rule 1002 to be very important, and changing it isn't something I

Re: [ossec-list] Re: Testing OSSEC

2017-08-23 Thread Ritu Soni 
Hello,
My work requirement is that OSSEC should generate an alert " Attack 
Detected " ,when the request from same ip address is received by the server 
for 3 or more times within 300 seconds.
I have done changes in syslog_rules.xml file:
**
*attacks|attack|automatic_attack*
*alert_by_email*
*DDOS Attack Detected*
*  *
But when i restart OSSEC,it generates an error msg:
*OSSEC analysisd: Testing rules failed. Configuration error. Exiting*.

Are these changes made correct?if not, please suggest the changes to 
achieve the same.
