Box is fully updated CentOS 5.5 (32 bit). DHCP is from the ADSL modem 192.168.1.1. After I update the DNS settings and restart the network, the DNS changes do not hold. I have tried using this GUI, as a regular user, after giving the root password, and, also, logged in as the root user.
When I begin, the Primary DNS is shown as 192.168.1.1 the IP of the ADSL modem. I move that IP to the Tertiary DNS and insert the Primary and Secondary DNS IP's I want to use. Then, I save the file, quit, and restart the network (service network restart). I see messages that the file has been saved and suggesting that I restart the network or the box.
The DNS I want to use is that of OpenDNS.com and I saw it work, briefly.Then,it stops working and when I launch the system-config-network GUI again, I see it has reverted to the original configuration, with only the Primary DNS of 192.168.1.1 (the ADSL modem) shown.
Questions: The "DNS Search Path" is blank. Is there something I should insert there?
If it appears that I am using the system-config-network GUI properly, what configuration file can I modify, to make these DNS changes hold permanently?
TIA! Lanny http://www.magazines-magazine.com/
Hi Lanny,
What if you manually edited resolv.conf and hard coded the dns info you want to use and in the /etc/sysconfig/network-scripts/ifcfg-eth0 file add "PEERDNS=NO" without the quotes. Restart network service or ifdown/up eth0.
May help.
