Squid and SSLBump

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I'm trying to configure my Centos 7 running:
Squid Cache: Version 3.5.28
configure options:  '--with-openssl' '--enable-ssl-crtd' --enable-ltdl-convenience

The certs/keys are legit from my company.

My squid.conf is very simple since it's for proof of concept

acl localnet src 172.16.0.0/12  # RFC1918 possible internal network

Browsing http sites works fine, but I am having issues with https

In my access.log I get:
1574346211.538     30 172.16.84.241 TAG_NONE/200 0 CONNECT www.cnn.com:443 - HIER_DIRECT/www.cnn.com - [User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko\r\nContent-Length: 0\r\nDNT: 1\r\nProxy-Connection: Keep-Alive\r\nPragma: no-cache\r\nHost: www.cnn.com:443\r\n] [-]


In Internet explorer I get the following:
