The only reason I'm using tftp is for nfs-boot/root for diskless clients and I am pretty happy atftpd and tftp windows users use then WinSCP or putty to exchange files with the server besides if you have something running on port 21 itshould be an ftp server. why don't you try what you have. Instead of disable it, why not remove it? Anyway, your descisions regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

On Thu, 5 Mar 2009, Star Liu wrote: i changed the port my ftp server use, then it starts. it's good, i'm not so stupid. Hi Star. I'd recommend against solving the problem that way. Ports are standardised so they may be found easily by those who needs them. As others have noted Inetd is the Internet superserver. If you look in /etc/inetd.conf (or /etc/xinetd.* if using xinetd) then you should see an entry where it is starting an ftp server on tcp/21. It shouldn't be starting anything else there unless you have a honeypot set up. So I'd recommend finding out what Inetd is starting, disable it and start your ftp server on the correct port. Having said that I wouldn't recommend ftp for anything except anonymous access. sftp is now widely supported in file transfer clients even on MS-Windows. sftp is a lot more secure and doesn't have any problems with firewalls like ftp does.

It manages Internet services and in many cases FTP server. http://en.wikipedia.org/wiki/Inetd Edit /etc/inetd.conf file, comment lines that enable ftp server and restart inetd daemon (invoke-rc.d ...), check with netstat -laptn that no program uses TCP/21, and then start your FTP server. Another solution is to remove inetd package, if you really don't use it. Regards. Yann. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
