Its very Linux-centric and i gave up for the moment when i realized how much work it would be to port it. Brian's ppp over i4b does support deflate compression and i get very good results out of it - too good to put more work into the above URL. > today... impressive stuff.) and is someone working on linking i4b > and netgraph? There will be a netgraph node interface which will link an i4b B-channel to netgraph. There are no plans from my side to netgraphify the D-channel part of i4b. > that seems to be the logical way to do more complex > stuff like this aodi thing that e.g. the german Telekom wants to use > for their low-bandwidth 10 DEM/month isdn `flatrate' which they plan to > introduce around the end of the year.

Since i'm not such a beast and will probably never become one its of not much use for me. - my usage of the internet is not much compatible with what this "flatrate" offers. - the Telecom does not give away anything for free. Check when, why and most important how you are using the internet: the savings you get using this "flatrate" does not pay even a fraction of the time and work needed to implement this - in my eyes. Anyway, i will happily accepting (clean) code which implements it :-) hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
