        take a look at tripwire from gene spafford and gene kim at purdue.
version 1.2 was released just last month.  it will monitor any files you 
want for changes in any of the fields returned by the lstat() syscall.  
this includes size, modification time, owner etc.   it  will also 
checksum those files using the checksum you specify, from simple 32bit 
crc to cryptographically strong signature algorithms.   you can run it 
out of cron as often as desired.
