    Anyone interested in it?

    I'm trying to fix dansguardian code to support it.

    I would be interested in such a feature but I need to use it with squid + squidguard ;-)

    I'll start tests with squid too.  ;)

    which version of squid?

    starts working on squid 3.1

    Are you talking about full content (not just connect host) using dansguardian for ssl including the dynamic certificate generation to avoid the security warnings?  I understand that the clients would have to trust my root via other means.  Also I'd need to keep all the current functionality that your squid3 package has.  If so I could put up $100 for this.

    0
  • marcelloc

    Yes, full content filtering. On squid3, full URL filtering with squidguard.  dansguardian will need more work as the source does not has a full working config.

    So yes, then I'd put up $100.  How much are you looking for to get dansguardian set up with it?

    Oh, I haven't done a bounty before.  I wasn't sure if you needed more people to put some money up first or not.  Is the $100 enough to be worth it for you to do it?  If so I can send it to you tomorrow.  If not then would I send to the escrow to see if we get some other people to get it high enough?  I know you already put a lot of work into your packages for free which is great.  I wish I had more to offer but I'm trying to get this set up for home so no company backed funds. :(

    It will be great if more sysadmin that needs this feature donate a value.
    I'm not asking for a specific value, but how nice a ssl filtering feature will be on pfsense gui?
    BTW If you have in mind that this donation is to help on development instead of be sure it will be fixed, you can send it to me.

    Thanks for your help on it.

    I asked about an escrow but I guess you have to have the full required amount before they will do an escrow.  However right now we don't have a goal for it.

    i need this for squid and squidguard, dont require it much but will support development - $25

    bytheway the current squid in packages is 2.7.9 pkg v.4.3.3 so would this be also upgraded to 3?

    on behalf of a client add another $25

    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

    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.

    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.  :)

    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?

    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.

    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.

    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?

    @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.

  • X

    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
