Just like my editing of /etc/shadow from a normal account won't succeed.

This is also a known sign of potential intrusion. There needs to be some more 
investigation of the circumstances surrounding it, but almost all intrusion 
detection system look at both of these.

If it went to syslog, it would go to all users. That is not desirable and an 
easy way to DoS someone else on the same machine. The messages can scroll so 
fast that you can see what you are typing.

That's the basic idea. The events go to a central audit log analyzer in the 
data center and the admin can see that a particular machine went into 
promiscuous mode.
