I'm having an intermittent squid issue. It's plagued me with CentOS 5.x, Fedora 6, and now Fedora 11 (all using the RPM build that came with the OS). My DD-WRT router forwards all of my outgoing port 80 requests to my transparent proxy using IP tables. For some reason, squid will hang when opening a URL for up to two minutes. It doesn't always happen and sometimes restarting squid will correct the problem (for a while). The system is pretty hefty 3ghz P4 with 2G of RAM with a SATA II drive. That should be plenty for a small home network of about 10 clients. When I test DNS lookups from the host, requests are returned within less than a second. I'm pretty sure that's not the problem. Here is my squid.conf, any input would be greatly appreciated! acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl SSL_ports port 443 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 CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access allow localnet http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localnet http_access allow localhost http_access deny all htcp_access allow localnet htcp_access deny all http_port 3128 transparent hierarchy_stoplist cgi-bin ? cache_mem 32 MB maximum_object_size_in_memory 128 KB cache_replacement_policy heap LRU cache_dir aufs /var/spool/squid 4096 8 16 max_open_disk_fds 0 minimum_object_size 0 KB maximum_object_size 512 KB access_log /var/log/squid/access.log squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern (cgi-bin|\?) 0 0% 0 refresh_pattern . 0 20% 4320 visible_hostname doug-linux.dougware.net unique_hostname doug-linux.dougware.net coredump_dir /var/spool/squid cache_mgr admin@xxxxxxxxxxxx dns_nameservers 10.0.0.254 10.0.0.253 69.197.163.239 store_avg_object_size 64 KB memory_replacement_policy heap LRU tcp_outgoing_address 10.0.0.254 udp_outgoing_address 10.0.0.254 Thanks Doug Eubanks admin@xxxxxxxxxxxx 919-201-8750
