Thanks to all who have responded so far. I attempted to send an update
yesterday, but failed so here's what I've learned so far...
First some background:
----------------------
I can do ppp to the Linux server in question from another Linux box.
This is done using a special login (user name ppp) who's default shell is
a script which launches pppd on the server.
My goal is to do ppp from Windows 95 to this same Linux server. I can do
this, but not with the ppp login mentioned above. Instead I must setup
W95 to give me a terminal window instead of attempting to login
automatically. I login as a different user (one who has a bash shell)
and execute the script which serves as the shell for the ppp user then
hit continue and I'm in like flynn... (I'm really interested in why
logging-on with the terminal window works, but the automatic login fails,
but I can accept this login process - it's not pretty but it works.)
Remaining problem:
------------------
Although I can connect and establish a ppp session with the Linux server,
I can only see myself and the Linux server when I go out and ping
around. W95 is setup to use the default gateway of the host (i.e. the
Linux server), but it doesn't seem to be doing this. I've tried
establishing gateways statically on the Windows 95 machine (client) to
point to both the Linux server or the Linux server's default gateway,
but I still can't see beyond the Linux server. The script I'm running on
the Linux side upon login is:
#!/bin/bash
# This is the script to run as specified in the Network Administrator's Guide
# ppplogin - script to fire up pppd on login
mesg n
stty -echo
exec /usr/sbin/pppd <Linux server IP addr>:<Windows 95 client IP addr>
-detach silent modem crtscts netmask 255.255.255.0 debug
The output from this script upon login of the Windows 95 machine is:

It looks like some of the connection setup negotiations are not
successful, but this may be no big deal - the Windows box is setup to
support IPX and NetBEUI, so it may be a handshake for one of these
causing the 'Unknown protocol' message. What I need is for the Windows
95 machine to be able to see its DNS server. I've tried adding static
routes to the network where the Windows 95 machine expects to find its
DNS servers, and although the Linux box can get to them fine the Windows
95 machine can't. I realize this means I can't resolve host names, so
all my pings from the Windows 95 machine have specified IP addresses
instead - and I still can't get anywhere.
Thanks for any help anyone can offer.
