스마일 서브
Ubuntu 에서 VPN Client 설정해보았다.
패스워드 지정
vim /etc/ppp/chap-secrets
: ID / PW 지정
|
takakocap * 패스워드 * |
clinet 설정파일 생성
vim /etc/ppp/peers/kenseivpn
|
pty “pptp VPN접속아이피 or 도메인 –nolaunchpppd” name “접속할 VPN ID” remotename PPTP file /etc/ppp/options.pptp ipparam kenseivpn |
clinet 접속후 모든 트래픽이 VPN 서버를 통하지 않는다면 아래 스크립트를 삽입해보자
vim /etc/ppp/ip-up.d/route-traffic
|
#!/bin/bash NET=”10.0.0.0/8″ IFACE=”ppp0″ #IFACE=$1 route add -net ${NET} dev ${IFACE} |
실행권한 주기
chmod +x /etc/ppp/ip-up.d/route-traffic
pppd 접속하기
pppd call kenseivpn
정상접속시 VPN 서버로 부터 아이피 할당받음

프로세스 종료
|
killall pppd kill {pppd-PID} |
pptp 종료시 route 명령어를 통하여 ppp로 가는 라우팅이 잡혀 있으면 제거해야 한다
pptp 종료후 통신이 안될 수 있음
