SSL Bump for regex URL comparison

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

 



Good afternoon,

I have a small router onto which I have installed Squid.

I am trying to filter HTTPS urls for bad words on a blocked list. 

It will require the client on the safe side of the router to install the
certificate, this isn't an issue as it's an open process and not an
illigal MITM attack. 

Below is my squid.conf

As you will see I have been playing around with where to put the code
and what code to put in. 

I only have a small amount of flash drive so I have put the auto-gen
cert directory in /tmp/. I am aware this is volatile memory but until I
have a better solution I will be doing this. 

I have put a firewall rule in to forward 443 to 3128.

https://wiki.squid-cache.org/Features/SslBump
https://wiki.squid-cache.org/SquidFaq/SquidAcl

I also don't want to cache due to flash drive issues. Is this possible?

Its the same cert in /root/ and /certs/ before anyone points it out. 

Nothing has been appearing in the log files either but this is no
surprise.

Been up till 1am last few nights on this so you assistance is very
appreciated. 

Thank you very much,

Joe
