고쳐 쓰다

저는 오징어 프록시가 https와 작동하도록 하려고 머리를 쥐어짜고 있었습니다. SSL 범핑을 지원하고 활성화되어 있는지 확인했습니다. 나는 또한에 따라 인증서 등을 설정했습니다.https://support.kaspersky.com/KWTS/6.1/en-US/166244.htm하지만 여전히 작동하지 않습니다.

다음이 있으면 작동합니다: acl blacklist_ssl ssl::server_name "/etc/squid/blacklist.acl" http_access denial blacklist_ssl

그러나 내 url_regex가 작동하지 않는다는 사실은 ssl-bump에 여전히 문제가 있음을 나타냅니다.

내 구성 옵션은 ('--with-openssl' '--enable-ssl-crtd')입니다.

그런 다음 내 로그에 다음이 표시됩니다(작동해야 한다고 나와 있나요?).

저는 Ubuntu 20.04와 Squid 버전 5.2를 실행하고 있습니다. 여기서 무엇이 잘못되었는지 알 수 있는 사람이 있습니까?

고쳐 쓰다

좋습니다. 이제 다음을 통해 이 작업을 수행할 수 있습니다.

ssl_bump bump ssl_force_bump
ssl_bump bump all

그러나 여전히 원하는 동작을 얻지 못합니다. 만약 내가 가지고 있다면:

acl whitelist url_regex ^http(s)://bitbucket.org/products
acl blacklist url_regex ^http(s)://bitbucket.org/*

http_access allow whitelist 
http_access deny !whitelist blacklist

이제 모든 것이 블랙리스트에 등록되었습니다.https://bitbucket.org

URL의 하위 집합만 블랙리스트에 추가하려면 어떻게 해야 하나요?https://bitbucket.org

고쳐 쓰다
