welllll, start with the netgraph(4) manpage (not netgraph(3))
then you'll find MOST of the implemented nodes in /sys/netgraph,
though there are a couple of others (sync cards)
the mpd-netgraph port (under ports/net) can use netgraph to run pptp
vpns
and the ppp daemon (ppp(8)) can use netgraph to connect to
pppoe sessions running through DSL. (though it needs a
ethernet attached DSL modem.)
there is also an article on netgraph on Daemonnews
in the "blueprints (?)" section that is illuminating..
also check out /usr/share/examples/netgraph
for examples of how you might set up some configurations.
For a very conoluted example you may write yur own setup and control C
program
using the netgraph(3) library to control it. (that's what mpd and ppp
do)
