FC6 - DNS not remaining [Archive]

Hello,

I recently installed FC6 in the office of one of my friend, meaning that I did not use my own internet access. Each time I reboot the box, the primary and the secondary DNS have been erased and the only IP address which remains is 192.168.1.1 as the primary DNS. The major difference is that it takes about 15 secs to load an internet page :mad:

Each time I manually put both of the IP addresses in system, administration, network, it's erased during the next reboot, even if I use the save function available in the menu.

I think that a file is reinitialise during the reboot sequence but I too newb to solve this alone.

:(

I have been trying to set my DNS servers to OpenDNS, I'm also having this problem.

Under the System ->Admininstration ->Network, Highlight the interface your using and select "Edit". Under this screen make sure the box that allows user to configure the interface is checked, also there are 2 other selections, one is "Use DHCP" the other is "Obtain DNS Info", Uncheck the "Obtain DNS Info" then enter your own DNS server info. The primary should be your LAN interface on the router/switch etc, The Secondary should be the WAN DNS either your ISP/OPENDNS etc, and you could even put a third DNS ip in.

First of all thanks for your answer.

It seems that the box "allow user to configure the interface" remains checked after the reboot as well as the "obtain DNS info" one remains unchecked. Unfortunately, the DNS I put manually have been erased as usual

I finally add in /etc/sysconfig/networking/profiles/default/resolv.conf my provider's IP addresses and it works fine :)

There is also /etc/resolv.conf

There is also /etc/resolv.conf

that's right and it has been updated when I did the modification on the other one.
