VPN 호출 스크립트 열기: 인식할 수 없는 옵션: [AF_INET]

넷기어 R7000 라우터 토마토 v1.28.0000 -2017.2-kille72- K26ARM USB AIO-64K

내 스크립트를 디버깅하는 데 도움이 필요합니다.

목표: VPN API JSON에서 전달된 포트 번호를 검색하고 전송 원격을 사용하여 포트 번호를 실행 중인 전송 데몬에 전달합니다.

내가 어디서 잘못됐나요? 스크립트가 호출될 때는 OpenVPN이 실패하지만 셸에서 실행될 때는 실패하지 않는 이유는 무엇입니까? AF_INET 포인트를 어떻게 알 수 있나요? 이상하게도 오류의 IP 주소는 JSON에서 반환된 전달 포트 번호가 아니라 내 클라이언트 VPN 서버 및 포트입니다.

아래 Ipor Sircer 덕분에 매개변수 1을 정의하지 않음으로써 오류를 피할 수 있었습니다. 이제 내 입력은 단순화하기 위해 다음과 같지만 OpenVPN이 호출될 때의 출력은 스크립트를 직접 실행할 때와 매우 다릅니다.
