| Summary | 0002848: SQUID/Dansguardian shows a Access Denied page when page not exists | ||||||||
| Description | When we try access a page with a explicit permission in access policy the Squid shows a page informing "The dnsserver returned: Name Error: The domain name does not exist." However, our default policy is to use a Content Filter. When we try a page without the explicit permission the message is "Access Denied." | ||||||||

Nothing? |

I agree, this is misleading message. |

This happens with proxy set to non-transparent , when proxy is set to transparent the default browser message is displayed instead of the error "access denied" page. |

found the cause of the issue, but no solution, yet: our catch-all acls are these: acl all src 0.0.0.0/0.0.0.0 acl from_all src 0.0.0.0/0.0.0.0 acl to_all dst 0.0.0.0/0.0.0.0 which match all, but only ip addresses. in this case, we have a DNS resolving issue, so no ip address for the request. those catch-alls need to match also when there is no ip address. |

(0005557) peter-endian (administrator) 2011-01-31 12:11 |
acl all dstdomain none ?? probably, let's try. |

(0005575) peter-endian (administrator) 2011-02-01 10:30 |
good to know.. a line in squid.conf: debug_options ALL,1 33,2 or debug_options ALL,1 33,2 28,9 makes squid log in cache.log *why* a request has been blocked http://wiki.squid-cache.org/SquidFaq/SquidAcl#I_set_up_my_access_controls.2C_but_they_don.27t_work.21__why.3F [^] |

this is the problem: http_access allow from_localhost [...] http_access allow from_all to_rule0 within_timeframe_rule0 http_access allow from_all to_all within_timeframe_rule1 http_access deny from_all squid does: 2011/02/01 11:33:47| aclCheck: checking 'http_access allow from_all to_all within_timeframe_rule1 ' 2011/02/01 11:33:47| aclMatchAclList: checking from_all 2011/02/01 11:33:47| aclMatchAcl: checking 'acl from_all src 0.0.0.0/0.0.0.0' 2011/02/01 11:33:47| aclMatchIp: '192.168.11.55' found 2011/02/01 11:33:47| aclMatchAclList: checking to_all 2011/02/01 11:33:47| aclMatchAcl: checking 'acl to_all dst 0.0.0.0/0.0.0.0' 2011/02/01 11:33:47| aclMatchAclList: no match, returning 0 the to_all acl, is 0/0, but the request is no ip address in this case, but the unresolved domain. |

adding a rule which allows every domain helps. don't know if this is the best solution however: acl to_alldomains dstdom_regex .* http_access allow from_localhost [...] http_access allow from_all to_rule0 within_timeframe_rule0 http_access allow from_all to_all within_timeframe_rule1 http_access allow from_all within_timeframe_rule1 to_alldomains http_access deny from_all # http reply access rules http_reply_access allow from_localhost http_reply_access allow from_all to_all within_timeframe_rule1 http_reply_access allow from_all within_timeframe_rule1 to_alldomain http_reply_access deny from_all |

http_reply_access allow within_timeframe_rule1 instead of: http_reply_access allow from_all within_timeframe_rule1 to_alldomain is even better :) thank's to suggestions on squid mailinglist |
