rpi vpn client 설치 및 설정!

실은 odroid에 한거임 ㅋㅋㅋ

$ sudo apt-get install openvpn

인 줄 알았는데 굳이 이거 아니어도 되는건가?

아래는 좀 다시 내용을 봐야 할 듯..

$ sudo apt-get install pptp-linux

라즈베리에서 설치해보니 위에 패키지를 깔면 된다.

주소와 계정은 임의로 변조함

$ sudo pptpsetup --create TUNN --server vpntest.minimonk.net --username pi --password raspberrypi --encrypt --start Using interface ppp0 Connect: ppp0 <--> /dev/pts/9 CHAP authentication succeeded MPPE 128-bit stateless compression enabled local  IP address 192.168.219.205 remote IP address 192.168.219.1

원격으로 접속해서 크롬으로 접속하다 보니 영어로 나옴.. -_-a

아무튼 VPN 상태에서 Connected로 뜸!!

전혀 다른 아이피와 전혀 다른 NIC으로 접속이 됨

그런데.. 80번 포트 포워딩 해서 접속해보려고 하는데 이건 안되네..

터널 설정은 위에서 한 대로 pptpsetup을 이용하면되고

접속은

$ sudo pon TUNN

+

접속 끊기는

$ sudo poff TUNN

[링크 : https://wiki.archlinux.org/index.php/PPTP_Client]

이상하게 접속이 안되는 경우가 있는데, 일단은 SD 메모리 불량으로 EXT 파일 경고가 뜨는거 봐서는

시스템이 엉겨서 그런 듯..

$ sudo pptpsetup --create TUNN ... Using interface ppp0 Connect: ppp0 <--> /dev/pts/9 Modem hangup Connection terminated.

Ubuntu 14.04 에서는 커널 모듈 문제로 발생하는 경우도 있는 듯

접속 로그 보는 방법

# pon <TUNNEL> debug dump logfd 2 nodetach

[링크 : https://wiki.archlinux.org/index.php/PPTP_Client]

해보니까.. debug랑 nodetach만 해도 된다.
