PPP dialin server problem

PPP dialin server problem

Post by Thorheimdal » Mon, 03 Jan 2005 13:02:42



I had a ppp dial in server working perfectly with Redhat 9 (ppp 2.4.1)
(with windows 2000 and xp clients).
I have upgraded my server to Fedora Core 3 (ppp 2.4.2) and  now clients
cannot connect anymore...  I have used exactly the same options files
for ppp, so i really don't know what the problem is...  The Windows
clients give an error message that looks like "Your computer or the
server can not negociate PPP parameters".  I have attached my
configuration files and log.  We can see in the log that the
authentification have succeeded, but something goes wrong for network
address negociation...  Maybe version 2.4.2 have a different behaviour
than 2.4.1 with some options??

Server informations :

LAN address : 192.168.0.11
Router : 192.168.0.1
Client address (assigned by the server): 192.168.0.200

options.server file:

-detach
asyncmap 0

logfile /var/log/pppd.ttyS1.log
crtscts

I don't think so.  From what I saw in the log it's rather likely
that the server hostname is not assigned the IP address of it's
LAN Ethernet card (192.168.0.11) in /etc/hosts.  Or the pppd option
noipdefault configured somewhere - which should not be the case if
"exactly the same option files" are present now as with RH 9.

1. MST PPP for SCO Dialin PPP Server and Windows 95

Hi Friends,

I dialin to the MST PPP for SCO Dailin PPP Server from the Windows 95, I
saw the following problem.

1. Windows 95 can dialin, can give login name and password.

2. Windows 95 can see PPP negotiation characters. And then press F7.

3. "Verifying User Name and Password" appears on the Windows 95 screen and
cutoff the telephone line.

I analysing the log files so many days. I found the following.

1. The MST PPP for SCO dialin PPP server and Windows 95 negotiated the call
back negotiation.

2. I think, the callback on and the MST PPP is cutoff the line for callback
from MST PPP for SCO.

I looking for the MST PPP for SCO user guide and SCO web site, I did not
see the callback disable for the MST PPP for SCO PPP dialin server side.

If someone know, how to disable the callback negotiation function in MST
PPP for SCO, please e-mail to help me. I have very big problem in MST PPP
dial in PPP server and windows 95.

Please !! Help me .......
