Looks like permissions or ownership are wrong on your client.keys file, which would certainly explain the agent not being able to connect. I assume you’ve checked that the client.keys file exists and contains the correct information for the agent you are using as an example here?

Do you think the command you provided will fix it? It seems the install or CONF file went wonky during the install, but the agent has been reinstalled multiple times. root@adr318 # cat /var/ossec/logs/ossec.log 2015/12/14 07:30:51 ossec-authd: INFO: Started (pid: 3787). 2015/12/14 07:30:58 ossec-execd(1314): INFO: Shutdown received.

The firewall is allowing all UDP and TCP ports to pass through for our deployment. No traffic is being blocked to/from the OSSEC manager. We distributed OSSEC to an environment via Puppet and are able to get the agents to grab a client key over port 1515, but they are having issues connecting. A handful do eventually connect, but the majority don't, I don't see them come up in the OSSEC logs but they do appear as inactive agents. Any ideas as to why the majority of agents are not connecting, but do get their keys? -- --- You received this message because you are subscribed to the Google Groups "ossec-list" group.
