First check that you truly have the ftpd binary:
root at flame:/root# ls -l /usr/libexec/ftpd
-r-xr-xr-x 1 root wheel 96360 Jan 8 13:00 /usr/libexec/ftpd
Then see if ftpd is supposed to start as 'standalone' or as a
service controlled by inetd:
root at flame:/root# grep ftp /etc/rc.conf
root at flame:/root# grep inetd /etc/rc.conf
root at flame:/root# pgrep inet
root at flame:/root# grep '^[[:space:]]*ftp' /etc/inetd.conf
ftp stream tcp nowait root /usr/libexec/ftpd ftpd -l
If inetd is running, pgrep should report its PID as above.
Seeing no PID means that inetd failed to start. Your system logs
at /var/log/messages will almost certainly have clues about the
reason of the failure.
Then, start checking if something *is* listening at port 21:
root at flame:/root# netstat -na | fgrep LISTEN | grep [:.]21
tcp4 0 0 *.21 *.* LISTEN
root at flame:/root# sockstat -4 -l -p 21
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root inetd 651 5 tcp4 *:21 *:*
root at flame:/root#
If you don't have any indication how ftpd was started it's possible that
you manually fired up ftpd and then promptly forgot about it, until you
had to reboot. Stability is nice, isn't it? :)
