    SubjectTCP keepalive seems to send to only one port
    From

    I've been doing some experiments with the keepalive code in 2.4.0-test10 here
    (I want to avoid the 2.2.x NAT I'm using (for which I don't have root) from
    timing out my connections). To test it, I reduced both tcp_keepalive_time and
    tcp_keepalive_intvl to 1. Using ethereal, I saw that the keepalives were sent
    as expected, but only for one of the two idle TCP connections I had to a given
    host (I was testing with two remote hosts, each with two idle TCP connections,
    one in port 5500 and the other in port 5501). I only saw activity on 5500, yet
    netstat told me both were still active.

    This means that keepalive is useless for keeping alive more than one connection
    to a given host.
