Re: [SLE] Setting up ppp server for Win and Linux

here is what i have and it works with windows and linux clients /etc/ppp/options.server -detach # detach from ppp session (ie, run in background) asyncmap 0 modem crtscts lock require-pap # use pap authentication refuse-chap # dont use chap authentication #login proxyarp ms-dns 10.1.1.5 # sets the local dns server ms-dns 10.1.1.1 10.1.1.10:10.1.1.50 # sets the gateway and ip address for dial-in /etc/mgetty+sendfax/login.config /AutoPPP/ - a_ppp /usr/sbin/pppd file /etc/ppp/options.server and from /etc/inittab mo:23:respawn:/usr/sbin/mgetty -n 5 -s 57600 -D ttyS0 on both windows and linux i just setup a standard dial-up networking connection.

However, just to be thorough, I put in the username and password explicitly in pap-secrets. There was no change in the failure, or in the log entries.

I think my problem is in the way I have the client set up. None of the documentation I can find says what settings to make in the Windows configuration screens which would work with the way I have the ppp server set up..

Thanks, again, for your questions and suggestions.

I remember running into something like this a while ago. I think the login must be set in /etc/passwd and in /etc/ppp/pap-secrets . The pap-secrets entry must be plaintext for the username and the password. See if that doesn't do it for you.

Jonathan, thank for writing.

I did have this line in /etc/mgetty+sendfax/login.config, which is what I think invokes pppd in this situation. /AutoPPP/ - a_ppp /usr/sbin/pppd auth login I've just tried this again, and there was no change in the failure, or either of the log files.

Then, I left that change alone, and added "+pap -chap" to /etc/ppp/options: admin:/etc/ppp # grep -v ^# /etc/ppp/options | grep -v ^$

<snip> lock modem proxyarp login auth +pap -chap

When I tried this, again it failed with the same entries in both logs.

Thanks, again for your thoughts and suggestions.

Windows uses pap authentication to connect to a ppp server. I don't see where you have pap turn on in your options file or your parameters for pppd.

I'm trying to set up a ppp server which can be dialed into from either Linux or Windows PCs. I'm building this on a SuSE 7.2. host. I'm hoping to use the normal authentication (regular login) for the users in /etc/passwd, as opposed to setting up separate passwords in /etc/ppp/pap-secrets and chap-secrets. Right now, Linux users can dial in, using wvdial, just fine, with no problems.

When Windows users log in, they immediately disconnect after validating their user name and password. The error is something like "not able to negotiate a common protocol; make changes in Server-Types of Networking control panel." I'm trying to use a static IP on the client, but wouldn't mind using a dynamic one if that's easier.

In /var/log/messages, when a Windows client dials in, I get: Jul 18 10:25:02 admin pppd[27446]: pppd 2.4.0 started by root, uid 0 Jul 18 10:25:02 admin pppd[27446]: Perms of /dev/ttyS1 are ok, no 'mesg n' neccesary.

Can anyone tell me if anything's wrong with the setup on the server? Do I need to change anything on the Windows client? Any way to get any further information on the error or any diagnostics to run?

Thanks very much for your thoughts and suggestions.
