Subject: Audit and file watching
Date: Wed, 14 Jun 2006 13:41:29 -0400 [thread overview]
Message-ID: <44904A49.7090308@ornl.gov> (raw)
I have been using Audit's file watching ability to monitor when files
are opened. I decided to also try to monitor the deletion of files, so
I told audit to watch for all syscalls pertaining to a particular file.
I then tried opening the file, it worked as before. Then I tried to
delete the file using 'rm /tmp/test.c' the file was deleted from the
filesystem, but audit only showed two syscalls being performed: lstat64
and access. Audit also sent a message saying:
... audit updated rules specifying watch="/tmp/test.c" ...
lstat64 and access can not delete files on the filesystem, can they?
I expected to see unlink...
Any ideas?
Steve
