Hi All,

Hoping someone really clever knows the answer here (I asked on the
'questions' mailing list and I got no response).  This problem is really
getting to me - I can normally solve problems on my own with some googling
and reading the man pages, but this one has me beat.

Briefly:

4.8-RELEASE "ppp -auto" always dials 
Turned off sendmail - same result
Booted in single user mode - same result
Read /usr/share/examples/ppp, man ppp, ppp faq, searched google.

Need to know what or why the ppp link is being brought up.  Original
message with my config and logs below.  I was running 4.9-RC and as an
attempt to fix it I regressed to 4.8 (the day before 4.9 was released :-)

Many thanks in advance,
David

Hi FreeBSD'ers,

I've just upgraded to 4.9-RC (from 4.2) and I'm really happy with
everything except ppp. 

Whenever I start ppp (with ppp -auto pmdemand) it immediately starts to
dial - after connecting it briefly sends and receives a minimal amount of
data then sits there idly.

One other problem I've got with my upgrade is that I'm getting pam errors:

Oct 26 20:26:25 stoat login: no modules loaded for `login' service
Oct 26 20:26:25 stoat login: pam_open_session: Permission denied

(related?)

I've read the ppp faq and this question is covered and it says sendmail is
the often the culprit.  This rang loud bells as I saw that the more recent
version of sendmail has depreciated the 'nodns' feature.  So I tried
rebooting without sendmail running, but still the same problem.  I tried
killing off a few daemons including inetd, lpd, usbd.. but no joy.

I added "log All +tcp/ip" to get the full output, but I don't know enough
about this stuff to go further.  I initially get the following lines in
the log:

Oct 26 21:17:32 stoat ppp[466]: tun0: TCP/IP: OUT
<0>: fe80::240:95ff:fe44:3e11 ---> ff02::1:ff44:3e11 (72)

Oct 26 21:17:32 stoat ppp[466]: tun0: TCP/IP: OUT ICMP: :::135 --->
ff02::1:ff44:3e11 (16/64)

I've uploaded the rest of the conversation to:

http://www.carter-hitchin.clara.co.uk/logs/ppp.log.gz

My setup is an isolated workstation (no LAN, occasional dialup). Here are
some outputs:

I'd really appreciate some help here - I'm stuck in being able to
identify precisely what is using the link.

Many thanks,
David.
