A David Greenman special? :) Indeed. And before anyone asks, no, he's not giving away the sources. This isn't because they're secret and he's holding out for the Big Bucks or anything like that, it's simply that he doesn't like to release stuff which isn't ready for general consumption, and dg-ftpd is currently a "wcarchive special" which really would need significant documentation and packaging before anyone else could really figure out how to use it. He's also pretty busy now, so don't hold your breath. :) > I wanted to know how the limit on the number of anonymous users > was set. I was looking into PR #5109 and not wanting to re-invent Pretty much empirically - the number is moved around until the machine actually starts to swap and/or interactive performance suffers (and we can have as many as 10-15 active archive maintainers toiling away on there during the day who complain if the number of ftp or www sessions [which number several hundred also]) to the point where they can't work very well. Right now we seem to be bottlenecked on CPU, having eliminated memory starvation with our upgrade to 1GB. At 2750 ftp users, 200-300 www users and 10-20 interactive users (running the most godawfully large perl mirror scripts), we're just out of steam with a single P6/233. One thing we can get immediate relief on is moving the web server to another box entirely, and that's the planned next step. Jordan
