Ssl filtering transparent and non-transparent

Nachtfalke

bytheway, we would need to remove squid 2 and upgrade to squid 3 right?
would we still be able to use squid guard?

Yes!

on pfsense 2.0.3 you need to install first squidguard and then squid3
on pfsense 2.1 the package structure is new and you can first install squid3 and then squidguard

xbipin

is squid3 and squidguard currently stable compared to squid2 on 2.1 as i only use squid2 with squiguard on it currently

First squid3.3 devel release for pfsense is out.

What I'm sure is not working is antivirus integration via i-cap.
All other features should be working.

on packages I'll describe main changes.

I am just a home user but I love pfsense and the development community. I have not done any pfsense donations for a while. Can I send you a small token for your efforts?

Please PM me with details (paypal?).

Since version 2.1.2 of squid3-dev ssl filtering is working fine on 2.1 without patches and on 2.0.x using squid 3.3.4_1 from my repo. :)

so we first uninstall squid 2.7.9 and squidguard 1.4.4 and then install squid3-dev and squidguard again?

xbipin

i tried on a remote nanobsd test box and after configuring squid3-devl, it doesnt start the service and ig et this error in system log

May 23 13:25:11 	php: /status_services.php: The command '/usr/local/etc/rc.d/squid.sh stop' returned exit code '1', the output was '/libexec/ld-elf.so.1: Shared object "libgssapi.so.10" not found, required by "squid"'

Sasl needs some extra limbs from FreeBSD that is not included on pfsense.

You can fetch it from any 8.1 FreeBSD or from my personal repo

can u add it to the package itself so my client can simply install it and get going rather than doing it manually?

marcelloc

@xbipin:

Unfortunately no :(

I can only point package files to binaries on official repo.

I'll ping jimp again to put it on files.pfsense.org.

I can send you a patch/script that download all required missing libs.
Then you paste it on command prompt.

xbipin

try if jimp can do that if not then ill do it manually so send me that script

for SSL filtering does it need to be a genuine certificate or a self signed certificate will do?

marcelloc

@xbipin:

You need a CA for that.

To do not alert each ssl site filtered, you need to install CA crt on each client.

xbipin

i didnt understand that but what i need it to do is i want to block access to all sites, http and https and only allow the listed ones using squid and squidguard. the ones allowed are a few http and few https and i dont want to go about installing anything extra on client machines, is this possible?

marcelloc

@xbipin:

On current stable package(squid2 + squidguard), if you block domains and not urls and has clients browsers with proxy settings, then you can show squidguard error.

ssl_filtering from current squid-dev includes squidguard error message on

transparente ssl connections using domains or urls acls
non-transparent mode using url acls

With CA CRT installed on clients, you do not have Browsers cert alerts.

xbipin

basically im just blocking all domains by default and allowing the ones listed in transparent mode, i dont want it to do any content filtering, its just u block all and allow the listed and for the allowed ones u dont filter or restrict, full access.

currently on squid2 i allow domains and urls and its in transparent mode with no client side config and i squidguard gives errors as required but the problem is it does to port 80 only which is http, all i need is same but for port 443 (https) as well coz other than that all other ports r blocked for client using firewall rules

xbipin

so is this possible in squi2 or squid3-dev

transparent mode
when user goes to any https site, check its domain, if allowed then allow it direct connection or through squid, if denied then block connection and/or give error message
no client side config

currently on squid2 clients r blocked http connections to all domains except allowed ones but if they try like google or facebook etc using https they get access and the reason i cant block port 443 because few of the allowed domains only work on port 443 so i need to keep that open, jsut need a way to filter https domains as well
