I am unable to connect to my Linux server using a dial in PPP
connection, from a Win95 machine using DUN. I am using mgetty, which works
fine when connecting with a terminal program (i.e Hyperterminal). But when
I try to connect using DUN, I get an "Error 691:The computer you are dialing
in to cannot establish a Dial Up Networking connection. Check your password
and try again."
I am using a user name and password from /etc/passwd, which from what I
know should work by setting the "login" option in ppp/options.

I have a line in /etc/mgetty+sendfax/login.config:
/AutoPPP/ - a_ppp /usr/sbin/ppd

My /etc/ppp/options contains:
proxyarp
kdebug
auth
login
-chap
-detach
crtscts

I have also attached a portion of sys log messages containing a ppp
connection. (Where cleopatra is the user name):

Yes, but first it has to pass pap-secrets, which it apparently does
not.

Once you get that working you may fail for lack of IP addresses. When
using proxyarp, I believe you have to use an ethernet IP or hostname
for local IP on the server (since arp is related to ethernet hardware
address). See http://www.xnet.com/~efflandt/linux/dialin.txt

Here it fails too, but I get this line in my mgetty:
yS1 getlogname (FIDO AUTO_PPP), read:CLIENTCLIENTCLIENTCLIENT
##### failed dev=ttyS1, pid=7802, got signal 1, exiting

Try set debug level higher and see if you get something like this, too.
(Then we have the same problem ;-)

Have you compiled pppd with "make USE_MS_DNS=1" ?
