UGH this is a wrench in the works...
I was hoping to grab all the rotated logs, process them while still
allowing audit
to run with no interruptions. Problem I run into is I run ausearch -i
> /tmp/file and then
do ausearch -i /nfs/file with auditd stopped, then compare files and
if they are the same in
size then delete the /tmp/file. I do this to make sure I get the log
in the nfs archive directory
and the /tmp is a backup if there is a problem. If audit is running
there is no way the files will
be equal in size while processing the /var/log/audit data in two
different intervals.
It's a problem for me too.
I was thinking about just patching the ausearch code to behave as
desired...but hoping Steve beat me to it so there was a greatly reduced
chance of bad code...
:)
As for the archive issue, what I am planning is to make a snapshot of my
current audit log directory (technically the partition on which this
lives; that's another SECSCN issue), then rsync the snapshot over to a
backup server (via crossover network connection) and finally release the
snap mount. Then I do not have to compare file sizes ... and really the
size is only one indicator of correctness. You'd probably need a
checksum activity.
LCB.
