What's the problem

The net.ipv4.tcp_keepalive_time is off by a factor of ten. The comment says it should be set to 10 minutes, which is 600 seconds, and not 60.

You're right @trijpstra-fourlights , that value is wrong. I'll upload a fix as soon as I can. Thanks for warning about it.

I've corrected the net.ipv4.tcp_keepalive_time value to 600 seconds, as specified in its own explanatory comment.
