This would certainly cause this. Otherwise, try setting ``debug'' and ``physical'' logging. What does it say then ? > In ppp.log on my other machine (3.4 where it's all fine), I see lines > like, "tun0: Phase: deflink: /dev/cuaa1: CD detected." So what's up with > the carrier detect here, I don't know. There should be no carrier detected. Now that I'm in a position to check what happens, I see that basically you'll always see no carrier at the ``term'' bit (there is no carrier after all), but as carrier is optional by default, that's ok. There's a problem that ppp never checks for carrier - even after it receives its first LCP packet, but I don't think this has anything to do with your problem. To exercise this, try ``set cd 1!'' and then ``term''. It'll never succeed (unless you're already connected). The increased logging mentioned above may tell us more about your problem.... > Bill > -- > William Denton : Toronto, Canada : http://www.miskatonic.org/ : Caveat lector. -- Brian <brian@Awfulhak.org> <brian@[uk.]FreeBSD.org> <http://www.Awfulhak.org>; <brian@[uk.]OpenBSD.org> Don't _EVER_ lose your sense of humour !
