Hi Amos, Thanks for your reply. Ill try to explain better what im trying to do here. | You don't appear to have a: | Squid1->DG->Squid2 setup | | you do appear to have a: | Squid1 -> Internet or DG -> Squid1 -> Internet setup. | | Is there any particular reason you need to have two squid? | The current feedback config appears to be needlessly complicated for any | use I can think of right now for having two instances of squid running. In the scenario DG(port 8081) --> Squid(port 3128) Clients are using the proxy on proxy_ip:8081 Since Dansguardian cant handle NTML auth if I don't use 2 Squid instances then it will show on DG access log only the IP of the client and not the username. DG access log will look like this (only IP is logged): 2009.2.4 15:12:01 - 192.168.20.11 http://adimgs.sapo.pt/2009/odisseias/massagem.jpg *SCANNED* GET 1956 and on the Squid access log it will always show the localhost since the connenction comes from DG: 1233760323.286 8 127.0.0.1 TCP_MISS/200 1597 GET http://h.s.sl.pt/pub/botao.html?rand=&tile=36871 - DIRECT/213.13.146.180 text/html This would prevent me of doing reports on users usage and use I think delay pools. In the scenario Squid1(port 3128 for ntml_auth) -> DG(port 8081) --> Squid2(port 8080 for cache) Clients are using the proxy on proxy_ip:3128 DG access log will look like this (now user and IP are logged): 2009.2.4 16:01:12 rnuno 192.168.20.11 http://imgs.sapo.pt/images/footer/pt.gif *SCANNED* GET 804 and on the Squid access log: 1233763558.911 0 192.168.20.11 TCP_DENIED/407 2169 GET http://cache02.stormap.sapo.pt/vidstore02/thumbnais/66/91/02/15666_eDQus.jpg - NONE/- text/html 1233763558.917 21 127.0.0.1 TCP_MISS/200 2860 GET http://cache01.stormap.sapo.pt/vidstore02/thumbnais/05/64/67/ma_swing.jpg - DIRECT/212.55.154.131 image/jpeg So basically this setup is working in a way that allows me to do my reports and use delay pools but the error keeps on my log I thought that I has doing something wrong on the cache_peer line. 2009/02/04 16:09:15| WARNING: Forwarding loop detected for: Client: 127.0.0.1 http_port: 127.0.0.1:8080 GET http://cache03.stormap.sapo.pt/vidstore03/thumbnais/57/ed/03/731347_L4An1.jpg HTTP/1.0 Accept: */* Referer: http://videos.sapo.pt/ Accept-Language: en-US UA-CPU: x86 Accept-Encoding: identity,gzip,deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727) Host: cache03.stormap.sapo.pt Cookie: _swa_v=158287575757761020; _swa_uv=3752565023748371500 Via: 1.1 squid-ntml:8080 (squid/2.7.STABLE3) X-Forwarded-For: 192.168.20.11 Proxy-Authorization: Basic cm51bm86bm9wYXNzd29yZA== Cache-Control: max-age=259200 X-Forwarded-For: 192.168.20.11 I made some changes according to your advice but i still get the error. Do you have any suggestion on how to fix it or maybe another way to do what i want? Below is the conf's files im using now.
