On my Centos 5 server, the secure file has not updated since Dec 10. This despite the fact that I run an sshd server that I access many times per day. Most peculiar is the fact that a swatch monitor that I run on the secure file catches plenty of lines. It is as if when swatch catches a line in the file, the line is removed from the file and the modification date is set back. Hard to believe. Any ideas? Thanks, Mike.
