Hello, I have a problem to connect an embedded pptp client to a 64 bits pptp server. I have to establish this VPN connexion to forward a serial line through pptp. The symptoms are the following: Client side: ppd options in effect: debug # (from command line) nodetach # (from command line) dump # (from command line) noauth # (from /etc/ppp/options.pptp) refuse-pap # (from /etc/ppp/options.pptp) refuse-chap # (from /etc/ppp/options.pptp) refuse-mschap # (from /etc/ppp/options.pptp) refuse-eap # (from /etc/ppp/options.pptp) name GATEWAY-0004 # (from /etc/ppp/peers/tunnel) remotename pptp # (from /etc/ppp/peers/tunnel) # (from /etc/ppp/options.pptp) pty pptp 145.239.72.162 --nolaunchpppd # (from /etc/ppp/peers/tunnel) crtscts # (from /etc/ppp/options) asyncmap 0 # (from /etc/ppp/options) lcp-echo-failure 4 # (from /etc/ppp/options) lcp-echo-interval 30 # (from /etc/ppp/options) hide-password # (from /etc/ppp/options) ipparam TUNNEL # (from /etc/ppp/peers/tunnel) nobsdcomp # (from /etc/ppp/options.pptp) nodeflate # (from /etc/ppp/options.pptp) require-mppe-128 # (from /etc/ppp/peers/tunnel) noipx # (from /etc/ppp/options) Couldn't open pty slave /dev/pts/1: No such file or directory using channel 7 Using interface ppp1 Connect: ppp1 /dev/ttyp1 sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] sent [LCP ConfReq id=0x1 ] LCP: timeout sending Config-Requests and Server side: Sep 7 14:01:51 COORD-00020 pptpd[27671]: CTRL: Sending ECHO REQ id 1 Sep 7 14:01:51 COORD-00020 pptpd[27671]: CTRL: Made a ECHO REQ packet Sep 7 14:01:51 COORD-00020 pptpd[27671]: CTRL: I wrote 16 bytes to the client. Sep 7 14:01:51 COORD-00020 pptpd[27671]: CTRL: Sent packet to client The embedded device obtains it's 3G connection using pppd it also sometimes obtains the connection to the pptp server with the same connection. The embedded client uses pptp-linux_1.7.2-5_armel.deb and ppp_2.4.5-4em1_armel.deb The server uses pptpd_1.4.0-5_amd64.deb and ppp_2.4.6-3.1_amd64.deb The embedded device obtains the pptp connection every times when it is connected using ethernet (with the same config). I made a lot of search trying to find how make the connexion efficient using 3G access but this problem doesn't appears in any forum. Does anyone understand what is happening for my VPN ? Thanks in advance. |
