Check out "sysctl", it lets you change many things that are done by the
startup scripts.  For example:

sysctl -a |grep rfc shows:

net.inet.tcp.rfc1323: 0
net.inet.tcp.rfc1644: 0

sysctl -w lets you write values, while the system is running, including
tcp extensions:

sysctl -w net.inet.tcp.rfc1323=0
sysctl -w net.inet.tcp.rfc1644=0

It's a neat little interface to kernel doodads...
