call the following script as a cron job @ 3:10 on each host:
Code:
#!/usr/bin/perl
use strict;
use warnings;

my @stat=stat('path/to/file.txt');
if ($stat[9] > (time() - (60 * 60) ) ){ # last modified within an hour
   exec ('scp path/to/file.txt other.server:/absolute/path/to/file.txt'); #assuming you wish to replace the copy on the other node in the cluster
}

i-ls

i-ls(1) 						      General Commands Manual							   i-ls(1)

NAME

       i-ls - display file stat and checksum information for files

SYNOPSIS

       i-ls [-s] filename

       i-ls [-s] dirname

       Specify a filename for i-ls to examine, or specify a directory with dirname to examine all the files in the directory.

       -s

	      Do not show/calculate checksums for all regular files.

DESCRIPTION

       The integrit system detects intrusion by detecting when trusted files have been altered.

       integrit records information about files in a database.	i-ls allows the user to see that information for live files.

       The output syntax is the same as that of integrit.

EXAMPLES

	    i-ls /tmp/foo.txt

       shows file stat attributes for the file, "/tmp/foo.txt".

	    i-ls /tmp

       shows file stat attributes for all files in the directory, "/tmp".

	    i-ls -s /tmp

       shows file stat attributes for all files in the directory, "/tmp", also including also checksums for all regular files.

AUTHOR

       Ed L Cashin <ecashin@users.sourceforge.net>
