hello,
I am using RH9. my problem is that I have only squid configured on proxy machine and when i ping www.google.com from any internal host i am not able to ping it rather i can ping to google by specifying its ip address. what should i do? i have all machies with thier internal static ips.

Have you configured a DNS address in /etc/resolv.conf on the network boxes? If you are using a dsl connection then your modem/router probably has dns caching and you can use the router address to resolve the dns.

does that mean i have to add only one line on all internel pcs in resolve.conf like nameserver xxx.xxx.xxx.xxx where ip address is of routers static IP or else what?

Check your router. It should pickup the isp DNS address and have a DNS proxy. I only discovered recently that these routers do DNS caching and can be used. Enter the router ip address in /etc/resolv.conf in the form nameserver <ip_address> on each box. If that is not working check the DNS address the router is picking up and use that address. I have noted that since I specified the router address on my boxes that name resolution has been much quicker.

i have hardware router. how to get DNS proxy server IP? Router is connected to proxy server that i configured.

previously when i was runnig windows proxyserver with contents of resolve.conf
nameserver PROXY_SERVER_IP
search localdomain

I am able to ping any website by its name but when i boot proxy server to linux and start there squid i am unable to use ping with name of website instaed if i know ip of any site i am ping directly to that website.

Investigate installing dnsmasq on the proxy server then use the proxy server as the dns cache.
