Re: [CentOS] Changes to inodes discovered by aide
Hi Correct, looking at the log of prelink.full and prelink.quick the times match the inode changes using aide -c. thanks Jobst On Fri, Sep 28, 2012 at 09:31:19AM +0100, Tony Molloy (tony.mol...@ul.ie) wrote: On Friday 28 September 2012 03:03:31 Jobst Schmalenbach wrote: Hi.

[CentOS] Changes to inodes discovered by aide
Hi. On one of my servers aide just reported inode changes to a large bunch of files in a variety of directories, e.g. /usr/bin, /usr/sbin etc. This machine sits behind a couple of firewalls and it would be hard to get to.
