SquidGuard can be redirect the client to the block page using two different ways:
  • returning back a 302 HTTP code, the client than takes care to do the new request
  • faking the client and loading the block page then returning it back to the client

See this document for more info: http://wiki.squid-cache.org/Features/Redirectors

First scenario has one major drawback: the client must always be allowed to access the block page. This isn't true if the block page has the IP address of the green interface and the client does requests from the blue network. Beside this, if the client can't access sites with IP addresses (squidGuard ip-addr acl), the browser is forced to an infinite loop.
The second scenario addresses above problems, but it doesn't work correctly with TPROXY because part of the TCP connection is made by the proxy itself, so the client can't display the block page.

The best solution is to switch to a transparent proxy implementation based on DNAT and use the second scenario for squidGuard configuration.

#16 Updated by Giacomo Sanchietti about 5 years ago

This is not related to this package.
I just added the same note to #2967

You should see something like:
Category: unknown blacklist

The first unknown is the category for the source, and blacklist is the name of destination category.

Please can you post the matching lines from /var/log/squidGuard/urlfilter.log?

Maybe we can hide the unknown case.

#22 Updated by Giacomo Sanchietti almost 5 years ago

  • NEEDINFO changed from No to Yes

test case 2 : ok but blocked sites are not logged on urlfilter.log (may be this is the normal behavior in this filtering mode)

Yes, it is.

test case 4 : global whitelist override doesn't work (can't enable website access using the global whitelist)

What is the configuration? Can you paste the extract from squidGuard.conf and contentfilter db?

With this configuration, if a site is inside a blocked category and inside the whitelist, the site is still blocked. Should the whitelist always win? Even over custom categories?


[root@localhost ~]# db contentfilter show
blocked=category
    Description=
    Domains=www.nethesis.it

    BlackList=enabled
    BlockAll=disabled
    BlockFileTypes=disabled

    Description=Default filter
    Removable=no
    WhiteList=enabled
default_profile=profile
    Description=Default profile
    Filter=filter;default

Extract from squidGuard.conf:

    default {
        pass !blocked  !in-addr  whitelist  !blacklist  all
        redirect     http://192.168.5.246/cgi-bin/nethserver-block.cgi?clientaddr=%a&clientname=%n&clientident=%i&srcclass=%s&targetgroup=%t&url=%u
    }

test case 5: auth with local users: the authentications work, but I can't choose users when configuring profiles, just hosts and hosts groups

I can't reproduce the problem. Have you used the latest package? Current web interface always displays hosts and users, no matter how the proxy is configured.

[root@server ~]# db contentfilter show

    Description=Default profile

squidguard.conf:

    default {
        pass !test_category  whitelist  !blacklist  all
        redirect     http://192.168.56.115/cgi-bin/nethserver-block.cgi?clientaddr=%a&clientname=%n&clientident=%i&srcclass=%s&targetgroup=%t&url=%u
    }

With this configuration, if a site is inside a blocked category and inside the whitelist, the site is still blocked. Should the whitelist always win? Even over custom categories?

I think the most intuitive and easy to use behavior is : the global whitelist always win, also over custom categories and global blacklist

I can't reproduce the problem. Have you used the latest package? Current web interface always displays hosts and users, no matter how the proxy is configured.

I don't know how but I didn't have the latest package, after upgraded now I can see the users and hosts on dropdown menu.
