Hi all, I'm new to squid so bare with me. I just setup squid according to these instructions: http://www.howtoforge.com/dansguardian-with-multi-group-filtering-and-squid-with-ntlm-auth-on-debian-etch-p2 The setup is working but my logs are fill with these errors for every connection: 2009/02/03 17:20:15| WARNING: Forwarding loop detected for: Client: 127.0.0.1 http_port: 127.0.0.1:3128 GET internal://lis.moonlight.lan/squid-internal-periodic/store_digest HTTP/1.0 Accept: application/cache-digest Accept: text/html Via: 0.0 lis.moonlight.lan:3128 (squid/2.7.STABLE3) X-Forwarded-For: unknown Host: 127.0.0.1:8081 Authorization: Basic Kjpub3Bhc3N3b3Jk Cache-Control: max-age=259200 Connection: Close I know that these error is because of my cache_peer line iv been searching the web for the solution of this issue and i tried to separate the configs of the 2 squid instances but wen i did it the setup stop working. Does this error will hurt the performance of Squid how can i fix it without breaking the squi1+DG+squid2 setup? regards, --Ricardo Squid Cache: Version 2.7.STABLE3 DansGuardian 2.8.0.6 My dansguardian.conf changes: filterip = filterport = 8081 proxyip = 127.0.0.1 proxyport = 3128 usernameidmethodproxyauth = on forwardedfor = on Below is my squid.conf: http_port 127.0.0.1:3128 transparent http_port 8080 hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? cache deny QUERY acl apache rep_header Server ^Apache broken_vary_encoding allow apache cache_mem 1024 MB maximum_object_size 8096 KB cache_dir ufs /cache/squid 20000 16 256 access_log /var/log/squid/access.log squid cache_peer 127.0.0.1 parent 8081 0 no-query login=*:nopassword auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 15 auth_param ntlm keep_alive on auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Proxy Server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 # https acl SSL_ports port 563 # snews acl SSL_ports port 873 # rsync acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl Safe_ports port 631 # cups acl Safe_ports port 873 # rsync acl Safe_ports port 901 # SWAT acl purge method PURGE acl CONNECT method CONNECT acl NTLMUsers proxy_auth REQUIRED acl rede_interna src 192.168.20.0/24 acl h_trabalho time MTWHF 08:00-18:00 acl downloads url_regex -i .exe .mp3 .vqf .zip .rar .avi .mpeg .mpe .mpg .qt .ram .rm .iso .raw .wav .mov .iso http_access allow manager localhost http_access deny manager http_access allow purge localhost http_access deny purge http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost http_access allow NTLMUsers http_access deny all http_reply_access allow all icp_access allow all forwarded_for off cache_effective_user proxy cache_effective_group proxy coredump_dir /var/spool/squid
