PPTP VPN 연결 문제-모뎀 끊기

우분투 14.04에서 PPTP VPN에 연결하는 데 다음과 같은 문제가 있습니다.

1. ppp와 ppp-linux를 설치했습니다

2. / etc / ppp / chap-secrets를 다음과 같이 설정했습니다.

   113.41.242.167\\mark    PPTP    NaksOsP    *
   

3. 다음과 같이 / etc / ppp / peers / vpn1을 만들었습니다.

   pty "pptp 113.41.242.167 --nolaunchpppd"                                    
   name 113.41.242.167\\mark                                
   remotename PPTP                                
   require-mppe-128                                
   file /etc/ppp/options.pptp                                
   ipparam vpn1                                
   mru 1412                                
   mtu 1412 
   

4. /etc/ppp/options.pptp를 다음과 같이 편집했습니다.

   lock
   noauth
   refuse-pap
   refuse-eap
   refuse-chap
   refuse-mschap-v2
   nobsdcomp
   nodeflate
   

5. 그런 다음 응답없이 sudo pon vpn1을 실행하므로 다음 출력으로 sudo pon vpn1 디버그 덤프 logfd 2 nodetach를 실행했습니다.
