    Okay. If you use the same client program on FreeBSD and Debian to access
    netradio, you can check the settings on the FreeBSD client and compare
    them to the settings on the Debian client for any differences.

    Another thing you can check is ECN, which is a TCP extension that
    sometimes causes problems with broken TCP/IP stacks that don't implement
    it properly or at all.

    cat /proc/sys/net/ipv4/tcp_ecn

    This will show you the value of the setting. 0 is off, and 1 is on. If
    it's on, try turning it off, like this (do this as root):

    echo "0" > /proc/sys/net/ipv4/tcp_ecn

    If that works, you can set it to be permanently off by adding this line
    to /etc/sysctl.conf:

    net/ipv4/tcp_ecn=0
