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) G --
