This doesn't involve any special code, however. Otherwise the kernel is stock with only kernel config file and sysctl tuning. Most of the ability to handle that many users comes from a pain-stakenly optimized ftp server that I call 'dg-ftpd'. It's true that I have not made that available as freeware, but that's my perogative since I wrote it. -DG David Greenman Co-founder, The FreeBSD Project - http://www.freebsd.org Manufacturer of high-performance Internet servers - http://www.terasolutions.com Pave the road of life with opportunities.
