Re: tcp_keepalive

Thanks! That did it. But one detail:

Running sysctl doesn't save the new values for when I
next reboot, does it?

>From what I've found on the web for BSD, there should
be a /etc/sysctl.conf, but there's not. (I'm running
the Mac OS, so maybe darwin and Mac don't overlap
here.)

And if this helps anyone I put

net.inet.tcp.keepidle -> 8000
net.inet.tcp.keep -> 100
net.inet.tcp.keep -> 100

I arrived at these by extrapolating from values that
work on my Redhat machines. They are perhaps low, and
I'll experiment with them sometime.
