Dear All,

how easy/difficult would it be for an intruder to spoof file modification 
dates and sizes (i.e. the data which show up in an "ls -al")?

I have e.g. in my root directory:
/kernel          (3258128 Nov 20  2000)
/kernel.GENERIC  (3258128 Nov 20  2000)
Can I trust, that those are identical files (i.e. the kernel is still 
intact), even if somebody intruded?

Tnx,
Stefan
