Squid ClamAV Not Reporting Virus'

mtarbox

I decided to test mine and it too is not triggering the warning or the blocked pages.
I am not using HTTPS/SSL Interception, but I would expect it to block the http files.
I've uninstalled squid, rebooted, and then re-installed squid, however still no dice.

2.4.2-RELEASE (amd64)
built on Mon Nov 20 08:12:56 CST 2017
FreeBSD 11.1-RELEASE-p4

c-icap and clamd both show a green light status.

C-ICAP Server Table shows as empty, even after downloading the eicar test file which it doesn't catch.

And upon further discovery on the web, this was my solution. Not sure if it is correct, but it is once again working. https://www.ceos3c.com/2017/06/23/install-squid-clamav-pfsense-2-3-3/ except I did not have to set the proxy on my browser since it was already in transparent mode.

So it makes me wonder what exactly I did to knock c-icap offline and not scan traffic, even though it was showing the green light status. I can't remember testing it after updating to 2.4.2, or even the prior release.

No sure why we need FW rule it used to work before w/o it?

Tried as was suggested by @mtarbox https://www.ceos3c.com/2017/06/23/install-squid-clamav-pfsense-2-3-3/ and still no love

??!!

If I were to guess I'd say that Transparent Proxy Settings stopped working roughly at the time of upgrading to 2.4.1

I don't get the response page but it is blocked and I don't use a firewall rule.

I have squid setup with mitm and transparent.

When I check the real time tab the (clamd table) show's the eicar file is found instream
and also the C-ICAP server is showing that it generated a response page even though
none appeared.

I had just assumed it was a conflict between one of the other package's I have installed.

Just updated squid to 4.42_1 and I am now getting the response page with http and https.

Hi Yuri,

Sorry for the response delay. I have pfsense 2.4.1 running and the virus test files are well detected.

So to clear you cache proceed as follow:

Stop Squid service: on the "Package / Proxy Server: General Settings / General" interface uncheck "Enable Squid Proxy" checkbox and save the configuration. This will stop the service.

Execute command: rm -rf /var/squid/cache/*, the cache is destroyed.

Rebuild the cache space using: /usr/local/sbin/squid -z (type enter again to have the prompt). The swap space is rebuild.

Restart the service from the Web interface by activating the "Enable Squid Proxy" checkbox and save the configuration.

Works fine, pfsense is a great product.

Interesting, what did you do? and it did not work before 2.4.2p1 ?

Thx

i did exact those 4 steps… all thru "command promp" webGUI page.

I originally was on 2.3.4p-something........ upgrade to 2.4.2 broke everything, so I had to fresh install, and restore the XML file.

Once the backup file was restored, I could download all the HTTP EICAR files no problem.

then followed those 4 steps, and i get the virus redirect page. (could not download the EICAR files)

Oops you are right, works for me too now!!!

So seems like 2.4.2-RELEASE-p1 fixed it (and last time I tried on previous version).

Thanks :)

I'm now on pfSense:
2.4.2-RELEASE-p1
FreeBSD 11.1-RELEASE-p6

Using a Mac mini and MacBook Pro both using Firefox to test the EICAR HTTP files, I completed the 4 steps, twice, and I can still download the HTTP files. I haven't configured for HTTPS yet.

Another interesting factoid…Using Debian 9 Stretch Linux with Firefox installed, I couldn't download the HTTP files but I still didn't receive the red colored virus message.
