I am also very happy with native ftpd of 4.7(lukemftpd not tried). It can process over 1000 connections if you tuned socket parameters(such as mbuf clusters) properly. proftpd cannot handle such situation. One bad point of native ftpd is simplicity.(also good point of ftpd) It cannot limit total users or total bandwidth. It can allow unlimited connections (that's too bad if too many requests come in) so I gave up running standalone mode and use inetd to limit total connection and per-ip connection. a little bit overhead, but reasonable. And it doesn't support wu-ftpd style xferlog(8) format. You need to convert ftpd's /var/log/ftpd log properly if you wish log analyzing. I think thttpd-style ftpd(single process, use kqueue() model, mmap() caching or utilizing sendfile() ) will be perfect solution for high load. But I cannot find such ftpd yet... I have the following entry in /etc/inetd.conf: ftp stream tcp nowait/800/1200/1 root /usr/libexec/ftpd ftpd -l -T 30 -t 15 -S > -- > Maxim Konovalov, maxim@macomnet.ru, maxim@FreeBSD.org > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-hubs" in the body of the message -- CHOI Junho <http://www.kr.FreeBSD.org/~cjh>; KFUG <cjh at kr.FreeBSD.org> FreeBSD Project <cjh at FreeBSD.org> Web Data Bank <cjh at wdb.co.kr> Key fingerprint = 1369 7374 A45F F41A F3C0 07E3 4A01 C020 E602 60F5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hubs" in the body of the message
