Also,check_diff dont works properly due this issue.
I think it's bug.



My ossec is 2.8 (rpm from Atomic repo)

part of my config:

<localfile>
        <alias>tcp_netstat</alias>
        <log_format>full_command</log_format>
        <command>netstat -tpln |sort</command>
</localfile>



Thank you!
