ip tunnel ... mode gre -- encrypted? or not?

[will trillich <will@serensoft.com>]

when a linux wonk says <with real IP's, of course>
	DEV=mytunnel
	OUTSIDE_HERE=321.1.2.3
	OUTSIDE_THERE=789.9.8.7
	ip tunnel add $DEV \
		local $OUTSIDE_HERE \
		remote $OUTSIDE_THERE \
		mode gre
is the tunnel encrypted? if so, how can i confirm
that? if not, is there a way to do so? (maybe some
argument needs to be supplied to insmod?)

and i still get
	root: /var/log# ip link show
	Cannot send dump request: Connection refused
	root: /var/log# ip link show
	Cannot send dump request: Connection refused
	root: /var/log# ip link show
	Cannot send dump request: Connection refused
with no messages logged under /var/log/* at all... ?
