Urgent! PPP inconsistency - 3.1

[Robert Brott <robertb@mbox.com.au>]

**Please reply directly if possible, as I have been waiting for over an 
hour for majordomo to acknowledge me on the misc list, but can't wait 
anymore..**

I've been using OpenBSD since 2.9 and am not an expert, but know my way 
around.  I've been wrestling with this problem for several days, with 
no luck.  It may seem initially like user error, although I am 
confident there is something else..

I use ppp to get online, and share this (slow) connection between other 
boxes on my home network via NAT, using 2.9.  My IP Address is 
dynamically assigned by my ISP; Australia's 'iPrimus'.  I've 
successfully been using 2.9 to facilitate this connection, and am now 
attempting to migrate to 3.1 (which I have lready done successfully on 
my samba server).  I am installing fresh, so as to ensure the 
distribution is clean and (theoretically) working.

PPP doesn't work as it should.  I used the exact same configuration 
parameters in setting it up, as I have in 2.9's ppp.conf (as shown 
below):

/etc/ppp/ppp.conf

..

default:
 set log Phase Chat LCP IPCP CCP tun command
 set device /dev/cua00 #the serial port to which the modem is connected
 set speed 115200
 set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK 
ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"  

..

primus:
 set phone 99232000
 set login
 set authname xx
 set authkey xx
 set timeout 120
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
 add default HISADDR
 enable dns

..

Note that this file is produced by -
> "cp /etc/ppp/ppp.conf.sample /etc/ppp/ppp.conf" so I *am* using the 
correct version of the file.

ppp is then invoked by: "gw-inet# ppp -auto -nat primus", although more 
recently I have been trying to get ppp working *without* NAT ("gw-inet# 
ppp -auto primus") -> this seems more logical to me in isolating the 
problem.

I have read the manual page on 3.1 from cover to cover several times, 
and can find no indication that the configuration for this setup has 
changed at all.  Furthermore, I am aware of two others whom I know 
personally, who have had ppp in 3.1 working without issue using the 
*exact* same configuration as myself (but a different ISP).  I know it 
isn't ISP error, though, because when i install 2.9 and set up ppp (in 
order to stfw a little more and try to find some more clues) it works 
flawlessly.

Here is some of the errors I've been getting in 3.1:

Jun27 18:02:13 gw-inet ppp[17995]: tun0: Warning: iface add: ioctl
(SIOCAIFADDR, 210.50.220.102/24 -> 0.0.0.0: File exists

And

Jun27 18:02:13  gw-inet ppp[17995]: tun0: Error: ipcp_InterfaceUp: 
unable to set ip address

And

Jun27 18:02:13  gw-inet ppp[17995]: tun0: Warning: ff02::%tun0/32: 
Change route failed: errno: Undefined error: 0

I also have a ppp.log but I won't include it unless someone 
specifically asks for it, don't want to make this too long.  By the 
same token, I'm not sure how much a dmesg would help, but I can include 
it if need be.

If anyone has come accross this, or knows why this may be ocurring, 
please help! Again, please reply directly..

I love this OS and I don't know what's going on :|
