Hi, Squid-2.5-STABLE12 + ip_gre WCCP + RHEL v4 U2 + 4Gigs RAM + Cache Dir to be 45 Gigs, but only 20Gigs now I have a high volume network ( /19) I had to increase the number of file descriptors and rebuild squid. Now it works Ok, But I notice a major slowness in browsing the internet. Plus site with streaming media take too much time to load. From some parts of my network, I get "Unable to reach Website answer" This is my config, --------------------------- iptables -nL -t nat Chain PREROUTING (policy ACCEPT) target prot opt source destination DNAT tcp -- [MyNet]/19 ![MyNet]/19 tcp dpt:80 to:[Cache IP]:3128 ----------------------------------- http_port [Cache IP]:3128 icp_port 3130 hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY cache_mem 256 MB cache_swap_low 90 cache_swap_high 95 maximum_object_size 4096 KB minimum_object_size 0 KB maximum_object_size_in_memory 8 KB cache_dir ufs /usr/local/squid/var/cache 20240 16 256 cache_access_log /var/log/squid/access.log cache_log /var/log/squid/cache.log cache_store_log /var/log/squid/store.log mime_table /usr/local/squid/etc/mime.conf pid_filename /var/run/squid.pid auth_param basic children 5 auth_param basic realm Squid proxy-caching web 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 443 563 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews 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 CONNECT method CONNECT acl myacl src [MyNET] http_access allow myacl http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports acl our_networks src [MyNET] http_access allow our_networks http_access deny all http_reply_access allow all icp_access allow all icp_access allow all tcp_outgoing_address [CacheIP] cache_mgr postmaster@xxxxxxxxxx cache_effective_user squid cache_effective_group squid visible_hostname cache.domain.com httpd_accel_host virtual httpd_accel_port 80 httpd_accel_with_proxy on httpd_accel_uses_host_header on logfile_rotate 10 forwarded_for on cachemgr_passwd ***************** snmp_port 3401 snmp_access deny all wccp_router [Router IP] wccp_version 4 wccp_outgoing_address [CacheIP] coredump_dir /usr/local/squid/var/cache How can i improve it ? so the all the serveices ate allowed without restriction ?
