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. ~Jeff On Tuesday, January 28, 2003 12:00 PM, mazdaracer wrote: > I see 21 below.
