Re: PPP over ATM
Sorry to chime in so late, but ppp(8) already has ATM support... I must confess that I haven't tested it and don't know how it works, but it may be worth looking at. A netgraph node would definitely be preferable. On Sun, 22 Oct 2000 03:41:27 +0200, Poul-Henning Kamp wrote: Who knows about the ATM stuff in the kernel?

We already have ppp over ethernet and other transports using netgraph, (and mpd (in ports) already uses teh netgraph kernel ppp stack) I am not familiar with netgraph could you point me to some info? The hardest part from my perspective is finding the info for the drivers for the ATM (I assume you mean ATM as used in DSL) DSL cards. We already have some ATM support so it would be a case of just working out how to best hook it all together, preferably with netgraph as the framework to do so. Well it is for DSL but, the adapter he has is already supported by FreeBSD. Just the PPP over ATM is an issue.

PPP over ATM
I was wondering what the state of PPP over ATM is, if there is at all. And would like to offer my services in it's development if it isn't finished (or started) yet. I inquired on #FreeBSDHelp on EFNet but I didn't get any useful results. I am not sure if this is the correct place to be posting but I figured it could't hurt. Thanks!
