To summarize, the general consensus was that Sun's PPP daemon supplied with Solaris 2.5.1 is buggy and
not to be trusted. It may suffice however, if you can get by with only one modem, and you are not talking
to Windows 95 clients. Brian suggested that it may not be the PPP but my getty. Changing to mgetty
may solve our problem as he suggested. I may try that. We are also looking at Suns commercial product,
"Soltice PPP". It is supposed to be more robust and less buggy. Anyway, we haven't decided on anything
yet, but when we are happy with something, I'll write those of you (who requested) back with our solution.
Following are the 5 responses I received.

The problem is not in ppp but rather the deamon that communicates with the modems. The only answer I know of to do authentication without using the terminal window is to use mgetty. We used it for quite a while and it is slick. Read the instructions and be sure to compile it with the autoppp option.

This asppp.cf file works fine :
-----
ifconfig ipdptp0 plumb sunppp up
path
inactivity_timeout 300 # Approx. 2 minutes
interface ipdptp0
peer_system_name xxxppp # The name we log in with
peer_ip_address yyyppp
debug_level 1
----
sunppp : is the IP-address for the serial connection on the server site
xxxppp : is the loginid for starting the connection (/usr/sbin/aspppls)
yyyppp : is the IP-address of the ppp-client (Win95)
Every client that connects gets the same fixed IP-address (yyyppp), this
is not a problem because we only have one modem so only one client can
be connected at a certain time.

Steve,
I have had similar problems getting Win 95 to PPP in to a Solaris 2.5.1
box. Sun has offered very little help. Alo, the debug flag on aspppd
does not work anymore. This is a bug I reported to SUN.
You can turn on a PPP debug log on the Windows side. I am not sure if
SUN can tell you much with the file, but if you have support from
Microsoft ( I can't afford it) , they may be able to tell you where the
SUN PPP server fails.
I have successfully used Win 95 PPP to dial in a local ISP called
Erol's Internet with no problem, so I suspect the SUN is the culprit.
Depending on the version of Win 95 you have, you may need to download
the login scripting software so that your Win 95 client can
automatically negotiate the login prompts and start PPP on the SUN.
Check the site www.windows95.com for the download. With this you can
automatically login w/out the terminal window.
Please let me know how and if you resolve this problem. I have been
chasing this down off and on for months. I don't require dialin to my
SUN via PPP, but it would make my life much easier.
Good Luck!!

Hallo Steve,
it seems you are using the PPP version bundle with the operating systems.
We also, and until now :-( we've got a lot of problems.
Regarding the problem you mentioned, we encountered it also, but at the moment
I don't remember the way we solved it (in any case I've just forwarded your
messages to my collegues).
If it can be useful for you, we use that Sun PPP assigning statically each user
its own IP address.
On the client side (we have Win31, Win95 and Mac) we suggest our people to use
a script (we provided them) to connect and therefore to unset "[ ] Bring up
terminal window after dialing" .
We inserted some delay inside the connection scripts.
In any case at the moment we are not satisfied of that PPP ;
we are evaluating the commercial version called Solstice PPP, that should
(I strongly hope so !) be more robust and should have more functionalities.
Be free to contact me for further details.
