resolv.conf is not updated automatically
 

hello all.

first, I have a strange problem with my fedora core 2 with kernel 2.6.6. at first, the problem was simply not to open any web site after connecting the internet. as soon as typed the address and pressed enter, mozilla gave the error "... could not be found" as if i am not online.

i asked this in general forum, and got no reply. then tried to connect to the internet using knoppix, and yep, i got it. I have the internet with knoppix.

I checked /etc/resolv.conf after booting knoppix, and it was nothing except a comment line. but right after connecting to my ISS, it automatically updated to:

and my conglusion was "this file should be updated automatically somehow." I noted down the server adresses there.

Now, I booted my system normally to fedora core 2, connected to the internet and checked the /etc/resolv.conf. OK, we have found the real problem; it is not updated... It always stays the same: nothing except the comment line, no nameservers defined there. I edited the file, and added the server addresses I noted down when connected to the net on knoppix, and OK, I can do it now.

now, anyone has any idea? why does this happen? how can I overcome this? do I have to edit the resolv.conf file every time I connect to the net?

your help will be greatly appriciated.

You don't say how you're getting your Internet connection.

Whatever programme you use to make the Internet connection, you need to set its option "use DNS server provided by ISP". I'm guessing that whatever you are using is set up not to do this.

Tell us more about your configuration and we'll see if we can help.

Cheers

dear kbcnetau, first of all thank you for your response.

I use a dial-up connection with a standard 56K external modem, and -as you can guess- kppp is the dial-up tool I use.

I sought for any options of kppp as you said something like "use DNS server provided by ISP", but I couldn't get one. does it have such an option? or should I seek it anywhere else?

Although it's been quite a while since I used KPPP I do remember it having a place to enter your DNS servers.

* Start kppp and make sure that the account you are using is selected.

* Select Setup.

* With the account you are using highlighted, select Edit.

* You should see a tab labelled "DNS" - you can either set this to "Automatic" (recommended) or, if it does not work, you can select "Manual" and enter the IP addresses of your DNS servers.

This information is based on the kppp 2.1.2 which I have on my machine.

Hope this helps.

go to networking (used to be redhat-config-network)

OK I KNOW you are using dial up (like me) however select your ETH0 and click edit. Somewhere around there is a radio butteon that goes something like 'resolve dns names...' make sure its checked.
Its located below the dhcp and above static ip options.

Yes again I know your on dial up but this allows the dns/nameserver to edit the /etc/resolv.conf as needed....

A buddy of mine showed me this and it worked on fc2

doesn't work
 

Mr_C, i tried it.

I have an onboard ethernet card, but it was deactivated by bios' default settings. to do what you said i activated it, and kudzu configured it on startup.

then i did what you said, but it didn't work either. (the checkbox you mentioned was "Automatically obtain DNS information from provider") i also tried to restart the system, nop.

any other ideas?

but but I worked for me!
I don't really know where else to look :(

Ask you ISP for the nameservers that you should be using - try setting these manually in kppp (see post #5 in this thread).

thank you all guys.

i just wanted to have a solution to have the changes done automatically. I already edited resolv.conf manually. but this is not the matter. i am unsatisfied because i couldn't find the why, and couldn't solve this problem.

anyways, thank you very much again!

PS: if you have new suggestions about this, i will be waiting :)
