<snip>
I am running 4.2-S (sources as of February 7, 2001) and right now
I am surfing the 'Net after authenticating via the CHAP mechanism.
<snip>
I think I have found part of the problem - routing and the ISP. :(
Using my backup ISP allowed me to log on but that did not solve
the CHAP problem. It does not work with either ISP but the backup
ISP at least allows a manual login with username and password.
After the login the system trys to set up ppp and fails. Routing.
The system warns tun0 does not exist when I first boot up.
It does exist but running ifconfig confirms it does not exist
as far as the system is concerned.
The ifconfig tun0 line in /etc/rc.conf is being ignored.
So I booted from the GENERIC kernel, turned off all the
appropriate toggles in /etc/rc.conf and /etc/defaults/rc.conf and
tried again. Same thing, so I went back to my custom kernel. :|
After running ppp interactive the tun0 device will show up
because the ppp.conf file has:
set device /dev/cuaa1
which apparently links tun0 to the system and
set ifaddr 0 0
add default HISADDR
which supposedly allows setting all the routing information.
The ppp.log still shows ppp and my ISP disconnecting
after the link negotiation fails.
Neither side receives any response and they give up but
now the tun0 device exists for the system.

The docs say User ppp has to be started before natd.
But natd is configured before user ppp in /etc/defaults/rc.conf.
I tried moving the whole User ppp section before the natd
section hoping that would work but it did not.
# netstat -i
Routing tables
Internet:
Destination Gateway Flags Netif Expire
localhost localhost UH lo0
^^^^^^^^
Internet6:
Destination Gateway Flags Netif Expire
::1 ::1 UH lo0
fe80::%lo0 fe80::1%lo0 Uc lo0
ff01:: ::1 U lo0
ff02::%lo0 fe80::1%lo0 UC lo0
It looks to me as if tun0 is not being used and there is
no external interface.
# routed -T tracefile
shows routed struggling valiently to tell me it can not
find a route to the ISP nameserver (probably because
I am not actually on-line :)) then it sleeps for a while.

The other part of the problem is I keep getting side-tracked reading
docs, This List, source code and configuring other parts of the system
without crashing or destroying any existing data. So far, so good. :)
I haven't really needed to use the Internet because most of the docs
and information for using the system are included in the install.
This is the type of system I really wish I had twenty years ago and
there are some real gems in there along with the pabos.
