+If the system has multiple IP addresses,
+.Nm ftpd
+supports the idea of virtual hosts, which provides the ability to
+define multiple anonymous ftp areas, each one allocated to a different
+internet address.
+The file
+.Pa /etc/ftphosts
+contains information pertaining to each of the virtual hosts.
+Each host is defined on its own line which contains a number of
+fields separated by whitespace:
+.Bl -tag -offset indent -width hostname
+.It hostname
+Contains the hostname or IP address of the virtual host.
+.It user
+Contains a user record in the system password file.
+As with normal anonymous ftp, this user's access uid, gid and group
+memberships determine file access to the anonymous ftp area.
+The anonymous ftp area (to which any user is chrooted on login)
+is determined by the home directory defined for the account.
+User id and group for any ftp account may be the same as for the
+standard ftp user.
