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
