나는 맞춤형 Debian을 가지고 있습니다(debootstrap으로 구축).
Linux debian 4.9.0-4-686 #1 SMP Debian 4.9.51-1 (2017-09-28) i686 GNU/Linux
읽기 전용 파일 시스템이 있습니다.

그런 다음 새로 생성된 프록시를 사용하도록 firefox-esr(Debian의 iceweasel의 새 이름)을 구성했습니다. 수동 프록시 구성 http 프록시, SSL 프록시, ftp 프록시 = 클리어 "모든 프로토콜에 이 프록시 사용" = 클리어. ocks 호스트 127.0.0.1 포트 1080 에이전트가 없는 로컬 호스트, 127.0.0.1
그런 다음 http 요청을 수행할 때 아무 일도 일어나지 않습니다(브라우저가 정지될 뿐입니다). Tor(Socks5Proxy 127.0.0.1:1080 구성)를 시도했지만 동일한 작업을 수행했지만 ssh 터널은 아무 말도 하지 않았습니다(상세 모드에서는 출력이 없음).
tcpdump -i wlp2s0 port 1080
-> 트래픽이 전혀 없으면 다음을 시도합니다.
nc 127.0.0.1 1080
-> 아무 일도 일어나지 않는다
마지막 테스트이지만 관련성이 있는지 확실하지 않습니다. 터널을 종료하고 다음을 수행합니다.
nc -l -p 1080
인터넷 통계는 다음과 같이 말합니다.

iptables가 비어 있습니다.

결론: 문제의 원인이 ssh나 브라우저 때문이 아닌 소켓(?) 때문인 것으로 보입니다.
나는 거기에서 붙어 있었다.
당신의 도움을 주셔서 감사합니다! 작동하려면 이것이 정말 필요해요!
답변1
내 생각엔 이것이 읽기 전용 설정으로 인해 Lo 인터페이스가 시작되지 않는 것과 관련이 있는 것 같습니다. 이 테스트는 다음 증상과 일치합니다.
root@stretch-amd64:~# ip link set lo down
root@stretch-amd64:~# tcpdump -n -i lo
tcpdump: lo: That device is not up
root@stretch-amd64:~# nc -l -p 1080
당신은 단지 잘못된 인터페이스를 보고 있을 뿐입니다. lo는 localhost용입니다(IP에 관계없이 모든 로컬 연결에도 해당).
두 번째 터미널에서:
root@stretch-amd64:~# nc -w 5 -v -n 127.0.0.1 1080
nc: connect to 127.0.0.1 port 1080 (tcp) timed out: Operation now in progress
다시 첫 번째 터미널:
ip link set lo up
nc -l -p 1080
다시 두 번째 터미널:
root@stretch-amd64:~# nc -w 5 -v -n 127.0.0.1 1080
Connection to 127.0.0.1 1080 port [tcp/*] succeeded!
/etc/network/interfaces에 이 항목이 있는지 확인하거나 추가하십시오.
auto lo
iface lo inet loopback
그것이 있다면 읽기 전용 시스템으로 인해 ifup이 작동하지 않는다고 가정할 수 있습니다. ip link set lo up시작 시 어디에서나 실행할 수 있는 스크립트 가 있습니다 .
