Actually only 3 users are using the service, about 1 month ago, I have problems with connection and service that consistently falls, sometimes it can get 1 hour of connection and then falls, I neet to know that is causing this but can not find the solution, can you help please

My Server is on Centos , Kernell 2.6.18-53.el5PAE

This is my File on /etc/pptpd.conf

Code:

option /etc/ppp/options.pptpd

localip         192.168.10.1
remoteip        192.168.10.230-250

This is my File on /etc/ppp/options.pptpd

Code:

Not sure what anyone can tell you.

You say it was working, until about a month ago. I'd start with checking what changed a month ago, since something obviously did.

And did you try to Google for the error that you posted, from your messages file??? Lots of info. It looks like the problem you are experiencing is because of EAP authentication on the remote end, you'll need to pass "refuse-eap" option to pppd.

It's for Ubuntu, but references the same sorts of issues. Signs point to authentication/PAP-CHAP problems.

Doesn't matter what your clients are...you set that option on the Poptop server, along with whatever pap/chap options you may have to use. Read the links that were given to you.
