You don't turn off ports in /etc/services, that file is like a
database. You turn off services in /etc/inetd.conf:
$ man 5 inetd.conf ; man inetd
Are you sure you need port 21? You should use scp (secure copy,
part of SSH - secure shell) to copy files between systems. To see which
udp ports are open on your system:
$ netstat -an | grep udp
I am currently finishing up FreeBSD Security How-To .. when I am
done (a few more days), I'll post the URL here or something...
