can i know how to set up dns cache server?
do you have any useful website?
for your use, dnsmasq would do nicely. with the rpmforge repo configured...
# yum install dnsmasq # chkconfig dnsmasq on # service dnsmasq start
*done*
dnsmasq has some configuration options in /etc/dnsmasq.conf as well as man pages explaining more. there's some notes on it here, http://www.thekelleys.org.uk/dnsmasq/doc.html
