Hi all, I try to use linux pptp client in order to connect to a Windows 2003 Server but without any success. When i try to connect without authentication, it seems to work. So i try with PAP, CHAP, MSCHAP and MSCHAPv2 but it doesn't work. Here are my logs for a test with PAP: Sep 11 11:56:17 LinuxBox kernel: MPPE/MPPC encryption/compression module unregistered Sep 11 11:56:17 LinuxBox kernel: CSLIP: code copyright 1989 Regents of the University of California Sep 11 11:56:17 LinuxBox kernel: PPP generic driver version 2.4.2 Sep 11 11:56:17 LinuxBox kernel: PPP BSD Compression module registered Sep 11 11:56:17 LinuxBox kernel: PPP Deflate Compression module registered Sep 11 11:56:17 LinuxBox kernel: MPPE/MPPC encryption/compression module registered Sep 11 11:56:17 LinuxBox pppd[1834]: pppd 2.4.2 started by root, uid 0 Sep 11 11:56:17 LinuxBox pptp[1838]: anon log[main:pptp.c:243]: The synchronous pptp option is NOT activated Sep 11 11:56:17 LinuxBox pppd[1834]: using channel 1 Sep 11 11:56:17 LinuxBox pppd[1834]: Using interface ppp0 Sep 11 11:56:17 LinuxBox pppd[1834]: Connect: ppp0 <--> /dev/pts/2 Sep 11 11:56:17 LinuxBox pptp[1841]: anon log[ctrlp_rep:pptp_ctrl.c:243]: Sent control packet type is 1 'Start-Control-Connection-Request' Sep 11 11:56:17 LinuxBox pptp[1841]: anon log[ctrlp_disp:pptp_ctrl.c:721]: Received Start Control Connection Reply Sep 11 11:56:17 LinuxBox pptp[1841]: anon log[ctrlp_disp:pptp_ctrl.c:755]: Client connection established.
