Hi, I installed OSSEC ver 2 successfully on the Redhat, however when I try to start OSSEC using the command 'ossec-control start', I got the following error message
"Starting OSSEC HIDS v2.0 (by Third Brigade, Inc.)... 2009/03/23 10:01:38 rules_list: Group 'virus' not found. Invalid 'if_group'. ossec-analysisd: Configuration error. Exiting" I searched the problem on the ossec mailing list, Peter reported this similar problem but because Peter modified attack_rules.xml file. In my case, I have not modified any OSSEC file, I try to start OSSEC right after the installation is successful. Does anyone know why? Thanks a lot
