Question

我尝试配置squid（在openwrt上运行）作为ssl连接的透明代理。虽然＆＃34;正常＆＃34;当我尝试使用ssl连接运行它时，非ecrypted连接工作正常的鱿鱼总是崩溃。

我的配置如下：

https_port 3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/opt/ssl/ssl.pem key=/opt/ssl/ssl.pem              
ssl_bump server-first all

但每当我尝试启动鱿鱼时，我只会遇到一行错误：

Bus error

我正在使用Squid 3.5.2-2，调试日志如下所示：

所以现在我的问题是：为什么鱿鱼甚至没有开始？是什么导致了总线错误？

Answer 1

我很确定这是一个空间问题，尝试减少动态证书的大小：

dynamic_cert_mem_cache_size=1MB

你的Squid配置文件中的这个选项也很有用：

sslproxy_session_cache_size 500 KB

如果您仍然遇到总线错误，请使用 opkg 安装 strace 并尝试使用Squid。您将获得有关正在发生的事情的更多日志。
