[ossec-list] Problems after running OSSEC server upgrade 2.6 to 2.7,

[Francisco Jelves]

After running OSSEC server upgrade 2.6 to 2.7 final release, the / var /
ossec / logs / alerts / alerts.log is zero bytes.
The following command displays all disconnected agents: if Never connected.
. / agent_control-l

OSSEC HIDS agent_control. List of available agents:
    ID: 000 Name: serverxxx (server) IP: 127.0.0.1, Active / Local
    ID: 1024 Name: xxx, IP: any, Disconnected
    ID: 1025 Name: xxx, IP: any, Disconnected
   ...
    ID: 5575, Name: xxx, IP: any, Never connected
    ID: 5576, Name: xxx, IP: any, Never connected

Any recommendations? I'm thinking about going back to 2.6, but I'd like
OSSEC 2.7 server and use your new features.
Thanks a lot,
Frank
