[Openswan Users] ppp error: tty is not open yet

[weirauch at checkmobile.de]

hi all,
I seem to miss something quite basic :-) trying now since 4 weeks to get 
the vpn up and running - the ipsec seems to work, the l2tp also gets up 
(at least thats how i interpret it), BUT the ppp is not coming up with its 
ppp0 device. since I have no integrated modem but run over a system with 2 
internal ethernet network cards, I am not getting how to set up the ppp 
daemon to produce correct ppp0 devices :-(
system: opensuse 11.0, kernel 2.6.25.18-0.2-default, l2tpd from Jacco de 
Leeuw. (I read through the whole mailing list, and found nothing except a 
fedora user with a similar problem in 2004. the solution was there to get 
some "character devices" configured within the kernel. but I have no idea 
of how to do that with suse...)
i start the ipsec, than the l2tp, but what to do with the ppp? is'nt that 
a process which is called by l2tpd? and how do I "teach" pppd to come up 
with a ppp0 device?? (10 years ago with old modems I knew I did it, but 
now, without any modems, I am lost, somewhat - and all the ppp how-to only 
explain the "modem"-case...)
anyone with any helpfull idea?
best regards,
philipp

ps: below the var/log/messages from the experimental server.
the client is a mac-book pro osx (but that does not seem to be of any 
problem, right?)
