Is the traffic going in both directions?
How can I tell? There's no outside reason it shouldn't work. Ping
works on both machines to the other. No firewalls in between the two
machines.
Do the agents have multiple IP addresses?
No
Are they using the correct IP address?
Yes
Does the manager have multiple IP addresses?
No
Is it using the correct one?
Yes
Does the <remote> section in the ossec.conf on the manager configured
to use the secure method?
I haven't changed that file from the default, but this is it:
[r...@ackbar etc]# cat ossec.conf
