这个应该是因为proftpd仅获取到主机的hostname,并未获取到主机的IP,可以通过修改/etc/hosts文件解析本机的IP:

# This is a basic ProFTPD configuration file (rename it to 'proftpd.conf' for actual use).
# It establishes a single server and a single anonymous login.
# It assumes that you have a user/group "nobody" and "ftp" for normal operation and anon.
# ProFTPD需要系统内有一个用户/组nobody和ftp,实际上FreeBSD只有nobody用户/组,所以若要允许匿名登录,则需创建账号ftp。
