Not sure about the status of any open source projects to do this, but there are a couple of commercial implementations - Kencast and Talarian are two I've evaluated. Kencast supports linux and freebsd clients, but their "sender" is a Win2K server (no big deal, its been reliable for us 2+ years running). We use Kencast to distribute huge multi-gigabyte files via one-way satellite and it is incredibly reliable, due to the excellent forward error correction methodology. Good luck, --Lee PS -- As far as open source, search google for "multicast file transfer" and you'll come up with things like: "xtp": http://www.ca.sandia.gov/xtp/xtp.html "xftp": http://www.cc.gatech.edu/computing/Telecomm/playground/SCE/xftp.html "ftp-m": http://www.cs.ucsd.edu/Dienst/UI/2.0/Describe/ncstrl.ucsd_cse/CS2001-0684 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
