This will solve purpose for other applications also. I write second time about TCP Low Priority. It's a congestion control algorithm included in Linux kernel. Connections using this algorithm *should* use only idle bandwidth. In other words, such framework already exist in form of self-tuning TCP stack. Last time I wrote you asked for example code how to use it. Here you are, in python: #v+ #!/usr/bin/python import socket socket.TCP_CONGESTION = 13 sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_CONGESTION, "lp") #v- Module tcp_lp.ko will be autoloaded by kernel. So this setsockopt() call is ready to be put into yum-updatesd, just after socket creation. -- Tomasz Torcz -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
