Thanks for the reply
I've read the PPP-HOWTO, NET-3-HOWTO, IP-Masq-HOWTO and DNS-HOWTO but i
cannot find a solution. I am using RedHat 5.2 and using a ppp-on script
to dial out to the internet. The DNS Ip address i am using is the dns
of my isp and all of my hosts use the same DNS IP which works fine for
them. I am able to ping internet address by IP but not by name. My
hosts can ping the internet by both IP and Name.
Here shows some of my files in /etc
--resolv.conf--
nameserver xxx.xxx.xxx.xxx
--hosts--
127.0.0.1 localhost.name.ca localhost
192.168.0.3 486dx33.name.ca 486dx33
192.168.0.1 matthew.name.ca matthew
192.168.0.5 earth.name.ca earth
192.168.0.2 zx6r.name.ca zx6r
--networks--
loopback 127.0.0.0
localnet 192.168.0.0
--nsswitch.conf--
