Oh, ECN. Stupid broken routers. (As I understand it, ECN is
backwards-compatible with the TCP *standards*, but a number of
implementations can't deal with it.)

You REBOOTED!?  This isn't windows.  Just run
    /sbin/sysctl -p
after editing /etc/sysctl.conf, or merely run
    echo 0 > /proc/sys/net/ipv4/tcp_ecn
(which won't persist through a reboot, btw)

Now I wonder why the error message said it couldn't get root to
setuid, but the problem was a TCP timeout. Were all the error
messages the same?
