No, they don't all do it but you'd be hard pressed nowadays to find one
that didn't.  Anyway, most unixes are set up on the principle that
people *can* snarf your password file.  If you're a security-by-obscurity
fanatic, you might as well go the whole hog and get a shadow password
suite.

On the flavour of unix that I run, I haven't worked out how to get
it to log transfers except by turning ftpd debugging on (-d).  A bit
verbose, but it gives me what I want.

(I have moral objections to logging anonymous ftp transfers on public
sites, but this is *my* machine, and I have no public archives and
no users who would be ftp'ing in)
