auditd.conf/audispd.conf question...

All:

I have a quick question about the name_format parameter in audispd.conf. When selecting options that require a dns lookup are these issued for each record, or is the dns lookup issued one-time at startup? If dns lookup is done for each record I'd prefer to use USER and NAME to force the issue, though if not I'd rather just use the same file on all my servers.

I want to log both locally and to a central server. So which file should this be specified in /etc/audit/auditd.conf or /etc/audisp/audispd.conf or both?

Thanks in advance for any suggestions.

Regards,

Jim Richard

Its done at the beginning of the event loop so that it never needs to be 
looked up again.

Both. They are independent of each other.

Let me clarify. If you want the node name in both places, then you need to put 
it in both places. At a minimum, you would want it in audispd.conf so that the 
central logger knows where things come from. But you can leave it off the 
auditd.conf to save disk space unless you need it to match.
