Dear Developers & Users, we're using latest squidGuard for around 500 Users and match users against LDAP. Everything is working fine for a while and "bad pages" are blocked as they should. Randomly, squidGuard ist stopping to block the pages and the users have not limitations anymore. A reload of squid is fixing the problem. That is how we included squidguard in squid: url_rewrite_program /usr/sbin/squidGuard -d -c /etc/squidguard.conf url_rewrite_children 10 Any help or ideas are greatly appreciated. Please find attached the squidguard.conf dbhome /var/lib/squidGuard/db logdir /var/log/squidGuard ldapbinddn credentials ldapbindpass password src superprivusers { ldapusersearch correct-query } src moreprivusers { ldapusersearch correct-query } src noprivusers { ldapusersearch correct-query } dest porn { domainlist blacklists/porn/domains urllist blacklists/porn/urls log blocked_porn.log } dest ads { domainlist blacklists/ads/domains urllist blacklists/ads/urls log blocked_ads.log } dest ksi_a { domainlist blacklists/ksi_a/domains urllist blacklists/ksi_a/urls log blocked_ksi_a.log } dest ksi_b { domainlist blacklists/ksi_b/domains urllist blacklists/ksi_b/urls log blocked_ksi_b.log } dest ksi_c { domainlist blacklists/ksi_c/domains urllist blacklists/ksi_c/urls log blocked_ksi_c.log } dest warez { domainlist blacklists/warez/domains urllist blacklists/warez/urls log blocked_warez.log } acl { superprivusers { pass all redirect http://machine/sgerror.php?url=401%20site%20blocked&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u } moreprivusers { pass !warez !ksi_a !ads !porn all redirect http://machine/sgerror.php?url=401%20site%20blocked&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u } underprivusers { pass !warez !ksi_a !ksi_b !ksi_c !ads !porn all redirect http://machine/sgerror.php?url=401%20site%20blocked&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u } noprivusers { pass none redirect http://machine/sgerror.php?url=401%20site%20blocked&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u } default { pass !warez !ksi_a !ksi_b !ads !porn all # ### redirect http://localhost/block.html redirect http://machine/sgerror.php?url=401%20site%20blocked&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u } } thank you very much in advance Stefan Bauer
