If your /incoming needs to be usable for articles, you could just limit it to something like 2 kB/s per user. That's enough for legitimate articles, but for warez and porn it becomes effectively write-only. The only real problem is that people tend to upload the most worthless crap, so nothing interesting ever shows up in the 'harvesting' area. cheers, Rik -- IA64: a worthy successor to the i860. http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
