Does anybody know what Win95 PPP links try to negotiate? What is it looking
for as far as PAP or CHAP? I got two linux boxes connected by ppp, basic
connection, no authorization. I try to dialin with Win95, and then Win95 times
out saying that it's "can't negotiate a compatible protocol". I'm set up where
my Linux Server dictates local and remote IP address (ie. x.x.x.x:y.y.y.y in
the options file). I'm experimenting with 'usehostname', 'remotename <n>', and
'domain <d>' options for CHAP, but no luck yet. Thank's in advance for any
help.

It attempts to negotiate Microsoft CHAP (what pppd calls ms-chap80) and
PAP.

Use PAP, not CHAP.

Use PAP. Try the 'auth +pap login' options to pppd to make it use
/etc/passwd for authentication. Win95->Linux works fine here, so
it can be made to work. We use mgetty to answer the phone and
have it's "auto ppp" feature enabled. The command line it uses
when it detects a ppp connection attempt is:

/usr/local/bin/pppd auth -chap +pap login kdebug 0

Plus, our usual /etc/ppp/options file(s). Main things in there
are IP address and 'modem crtscts proxyarp'.

Try to use the option -debug when you start your pppd in your linux box.
The debugging goes into /var/adm/debug. It will tell you what goes wrong.
You can also look into /var/adm/messages and /var/adm/syslog to get a hint what goes wrong.

I believe Microsoft told me that Windows 95 will support either CHAP or
PAP. I haven't tried CHAP yet, but we successfully connect using PAP
authentication. The pppd process I have running is:

/usr/sbin/pppd -detach passive auth +pap /dev/ttyE0 38400

with the following in /etc/ppp/options:
crtscts
modem
asyncmap 0x00000000
mru 1000
mtu 1000

and the local and remote ip addresses in /etc/ppp/options.ttyE0

In /etc/ppp/pap-secrets, we have the expected
<username> * <password>

for each of our customers.

The serial port has a modem attached to it, so as soon as the modem
answers, the pppd process tries to do its thing and connect to the dial in
client.

Works great with Windows 95, Macs with FreePPP or MacPPP, and other linux
hosts. Doesn't work so well with Netscape Personal Edition under Windows
3.1. Don't know why yet.
