[ossec-list] syscheckd causing soft lockups

2017-02-28 Thread John Gelnaw
Was running wazuh 2.8.1 agent on "most" systems, with the wazuh ossec docker container for a master server. Upgraded to 2.8.3 to try to resolve this problem, with no luck. Out of about 160 machines, 4-5 of them will reliably wedge themselves after some amount of time with messages akin to:

Followup. ossec-syscheckd appears to be doing some bind operation: socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 6 bind(6, {sa_family=AF_INET, sin_port=htons(12310), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 close(6) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 6 bind(6, {sa_family=AF_INET,

Running the ossec server in a docker container, makes sense, and I run the Wazuh fork of ossec in their provided container with logstash / kibana4. Running ossec agent in a container makes no sense to me. I would suggest instead that you use the docker logging driver to reroute stdout from

to follow up to my own post-- First, the problem was indeed happening during ossec-rootcheck, but I was unable to determine what was failing. Secondly, the affected servers all were at one time or another, exporting a CIFS or NFS share. Disabling the share didn't prevent ossec-rootcheck from

As the default audit plugins for MySQL are somewhat horrific (XML is not a log format), and the log syntax for MySQL is multi-line, I've been looking for other options. The MariaDB audit plugin so far looks very nice-- It's highly tunable in terms of what it can report and it plays nice with
