Dear All, I have problem with SQUID-2.5STABLE9-7 in Fedora Core 4, sometimes browser in our client display "unable to determined IP Address from host name for www.google.co.id ", dnsserver returned " Timeout" but when i try to resolve using dig tools in SQUID proxy itself, the machine can resolve the query. Problem can be solved by restarting squid service. I install squid using RPM on P4-3 Ghz, 512 MHz. Here is my squid.conf http_port 8080 cache_dir ufs /var/spool/squid 1000 16 256 dns_nameservers 202.127.97.18 202.127.18.19 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 net1 src 10.100.0.0/255.255.0.0 acl net2 src 10.150.0.0/255.255.0.0 acl net3 src 10.10.0.0/255.255.0.0 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 http_access allow manager localhost http_access allow localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow net1 http_access allow net2 http_access allow net3 http_access allow localhost http_access deny all http_reply_access allow all icp_access allow all visible_hostname xxx.xx.xx my vmstat when dns error's displayed # vmstat procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 0 844 6148 17920 387332 0 0 4 49 44 48 3 1 96 0
