Thanks Tim,

Wouldn't a complete reinstall be overkill when it only "appears" that
someone put some mysterious files in an anonymous ftp incoming
directory?

It's not like someone cracked into the system, putting files in 
/var/ftp/pub/incoming is normal.  Unless, the ftpd that comes with
FreeBSD 4.4-Release has a gaping security hole I don't know about.

The default ftpd that comes with FreeBSD chroot's anonymous users and
has builtin commands so it should be quite secure, right?


	- Scott
