I'm currently following the handbook on how to dial into another machine
using ppp and having some difficulty getting a tun device working.  Here
is the output from grep tun mykernel:

pseudo-device	tun     1	# Packet tunnel.
pseudo-device	gif	4       # IPv6 and IPv4 tunneling

I then rebuilt this kernel, installed it and rebooted, but ifconfig -a
gives me the following output which shows no tun devices:

Did I do something wrong in my kernel?  Am I supposed to use a gif instead
of a tun somehow?

thank you
