Hello Amos, I changed my squid.conf according your recommendations. I'm facing a trouble that all IPs on unlimited_bandwidth file bypass authentication.
If I remove my ip from unlimited_bandwidth file and check the access.log working well: [04/Oct/2012:08:20:25 -0300] leonardo.abrantes xxx.xxx.xxx.xxx CONNECT TCP_MISS 200 www.google.com:443 (It's what I need) however, if I put my ip that file, the authenticaiton is being ignored: [04/Oct/2012:08:22:39 -0300] - xxx.xxx.xxx.xxx CONNECT TCP_MISS 200 www.google.com:443 #### http_port 3128 append_domain .contoso.local cache_effective_user squid cache_mem 2 GB cache_effective_group squid forwarded_for off httpd_suppress_version_string on visible_hostname proxy.contoso.local retry_on_error on pipeline_prefetch on auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp --domain=contoso auth_param ntlm children 30 auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic --domain=contoso auth_param basic children 20 auth_param basic realm Para prosseguir e necessario digitar seu login de rede. auth_param basic credentialsttl 1 hours acl localnetwork src 192.168.10.0/25 acl AuthorizedUsers proxy_auth -i "/etc/squid/default_access.acl" acl unlimitedBandwidth src "/etc/squid/unlimited_bandwidth" acl localhost src 127.0.0.1 acl java browser Java/1.4 Java/1.5 Java/1.6 cache_dir ufs /var/spool/squid 6144 16 256 coredump_dir /var/spool/squid maximum_object_size_in_memory 1 MB maximum_object_size 64 MB minimum_object_size 0 KB acl manager proto cache_object acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 8080 # 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 1025-65535 # unregistered ports acl purge method PURGE acl CONNECT method CONNECT delay_pools 1 delay_class 1 2 delay_parameters 1 -1/-1 65536/65536 delay_access 1 deny unlimitedBandwidth localhost delay_access 1 allow localnetwork delay_access 1 deny all logformat combined [%tl] %un %>a %rm %Ss %Hs %ru access_log /var/log/squid/access.log squid access_log /var/log/squid/gerencia.log combined cache_store_log /var/log/squid/store.log redirect_program /etc/squidGuard/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf redirect_children 30 http_access deny CONNECT !SSL_ports http_access allow unlimitedBandwidth http_access allow java http_access allow AuthorizedUsers http_access deny all cache_swap_low 90 cache_swap_high 95 dns_nameservers 192.168.10.2 192.168.10.3 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (zip|rar|tar\.gz|exe)$ 0 50% 259200 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 request_header_access All allow all #### can you help me please ? many thanks!!
