Just a follow up... I forgot to mention that I also did a tcpdump on tun0 as the link comes up - it shows no packets sent or received. From my limited knowledge of ppp negotiation, it looks like the link is being brought up but nothing is being sent over it. I also did a ktrace on ppp that didn't reveal anything which would indicate why ppp is dialling upon initialisation. One other thing is that after the initial dial, if I leave ppp to timeout, then it will not dial again, unless I do something (send mail, browse the web) - I've left it for at least 24 hours. This is strong evidence that the way ppp itself is setup is causing it to dial upon initialisation - is it testing the link? Is that some option somewhere?
