Re: bin/56129 (ftp(1) should keep control session during large xfer)

On my host that operation would set it to 40 minutes.

tcp(4) says the default value for TCP_KEEPIDLE is 4 hours, which
corresponds to

net.inet.tcp.keepidle = 14400

which means this value should be specified in seconds.

So if you have a device on the path with a 30min NAT translation
time-out, you'll still lose.
