[squid-users] Squid + SquidGuard : static block page not working

[Nicolas Kovacs]

Hi,

I've been working with Squid + SquidGuard for a few years, though only
on Slackware. I'm currently transferring my proxy expertise to CentOS 7,
and right now I'm having a little problem with that.

Squid works perfectly so far as a transparent HTTP + HTTPS cache proxy.

The next step is to add SquidGuard, so I installed it and edited the
most basic /etc/squid/squidGuard.conf file possible.

In this setup, my workstation (192.168.2.2) is allowed to access
anything on the Web, and all other client machines on the networks are
blocked and should be redirected to the avertissement.html block page
for every request.

--8<------------------------------------------------------------------
# /etc/squid/squidGuard.conf
dbhome /var/squidGuard
logdir /var/log/squidGuard

src admin {
  ip 192.168.2.2
}

acl {
  admin {
    pass any
  }
  default {
    pass none
    redirect http://nestor.microlinux.lan/avertissement.html
  }
}
--8<------------------------------------------------------------------

I appended the following lines to /etc/squid/squid.conf:

--8<------------------------------------------------------------------
# SquidGuard
url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf
url_rewrite_children 5
--8<------------------------------------------------------------------

Now this setup sort of works. My workstation can access anything, other
clients are blocked. Unfortunately, the block page avertissement.html is
not displayed. Instead, I get a Squid error page:

  The following error was encountered while trying to retrieve the URL:
  https://http/*

  Unable to determine IP address from host name "http".

Any idea why my static block page avertissement.html is not displayed?

Cheers,

Niki
