--ibfi4zPkg9 Content-Type: text/plain; charset=us-ascii Content-Description: message body text Content-Transfer-Encoding: 7bit Hi, We need some help with regards to ppp client program from FreeBSD (4.2 Release). We are trying to test the PPPoE/L2TP session establishment. In our case the ppp client host is directly connected to the LAC system, where PPPoE server, pppd server and LAC are running. LAC system is based on Linux 2.4.16 kernel. We are able to connect to the LAC and PPPoE session is established(PADI, PADO, PADR, PADS). After this, the pppd daemon on the LAC is sending LCP config requests with CHAP (MD5) option. The ppp client on FreeBSD host is not acknowledging the config requests and hence the LCP signaling is not completed. I would appreciate if some body can throw some light on why the FreeBSD ppp client is not responding to the LCP config requests from pppd. Specifically I would like to know if we need to use some configuration options to enable LCP signaling. Please find below the ppp.conf file on ppp client machine: --ibfi4zPkg9 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline; filename="ppp.conf" Content-Transfer-Encoding: 7bit ################################################################# # PPP Sample Configuration File # Originally written by Toshiharu OHNO # Simplified 5/14/1999 by wself@cdrom.com # # See /usr/share/examples/ppp/ for some examples # # $FreeBSD: src/etc/ppp/ppp.conf,v 1.2.2.1 2000/08/18 08:33:02 jhb Exp $ ################################################################# default: ident user-ppp VERSION (built COMPILATIONDATE) # Ensure that "device" references the correct serial port # for your modem.
