This is hard because they are selling bandwidth ("watch video") so they can't really cap the downloads, and they are selling always-on so they can't measure by time conveniently either. So they try to get the "bandwidth hogs" through contractual means. Comcast prohibits VPNs, and prohibits ~"attaching to another network", as examples. If you use too much bandwidth, they will use these to drop your service.There it is... how many bits is the customer actually moving? As for the person who mentioned modifying Linux IP code to alter the port range... it's a simple set of sysctl tunables in BSD (at least FreeBSD).
And it just came to my mind, a solaris machine uses by default high port numbers to open tcp connections: root@backup:~[15] > ndd /dev/tcp tcp_smallest_anon_port 32768 That settings determines which port number it uses to open outbound connection from what I know. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://seven.Alameda.net/~ulf/resume.html
