If you have lsof installed, that will tell you what's listening on port 21:
# lsof -i :21
COMMAND PID USER FD TYPE DEVICE SIZE/OFF INODE NAME
xinetd 256 root 4u inet 0x624b4908 0t0 TCP *:ftp (LISTEN)
Otherwise, as root, run netstat with some different args:
# netstat -nlp | grep :21
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN
256/xinetd
In both cases above, I can see that the process LISTENing on port 21 is
xinetd (PID 256).
Also, I missed the beginning of this thread. Is your ProFTPd installation
new, or is this something that used to work and then stopped working? If
it's a new installation, I would guess that your distribution installed an
FTP server by default (e.g. wu-ftpd) and that's what's listening on port 21.
