 Posted: Sat Apr 01, 2006 8:49 pm Post subject: changing dns with dhcp [SOLVED :D] |
 |
|
I would like to try a different dns server. Currently my router gets the dns servers automatically from my isp and my computer gets the dns servers from the router through dhcp. My /etc/conf.d/net was and I changed it to | Code: | config_eth1=( "dhcp" )
dhcp_eth1=( "nodns" )
dns_servers_eth1=( "193.205.245.5 193.205.245.8" ) |
Is this correct? How can I know if I'm actually using those dns servers? I tried to put some random numbers instead of a working dns server and I was still able to browse the web, so I think I did everything wrong and I am still using the dns obtained from my isp. Thanks in advance.

I think i can help you.
Changing the /etc/conf.d/net file isn't going to change anything until you do a
| Code: |
/etc/init.d/net.eth1 restart
|
Now the current dns server usually is gonna be in /etc/resolv.conf. If you edit this manually (no initscript restarting is necessary i think) you will use whatever you put in your /etc/resolv.conf. I think it's the first entry that gets tried first.
does that help?
oh yeah, btw are you sure you want to use a different dns server? I have trouble imagining why that would be a good idea... |

Hi erik and thanks for the answer, first of all, I already restarted net.eth1 when I tried the first time. Looking at /etc/resolv.conf confirmed that I am not using the dns server that I specified, but the one provided by the router through dhcp: | Code: | # cat /etc/resolv.conf
# Generated by net-scripts for interface eth1
nameserver 192.168.1.1
|
This is the ip address of my router, which is running his own dns server 
The reason why I want to change it is because I have this problem: http://bani.anime.net/banimod/forums/viewtopic.php?p=61777#61777 and I also have the impression that navigating in internet has become slow, mainly when I want to connect to a certain new domain, but then navigating in the pages inside that domain is fast as usual, so I thought that the cause could be a very slow name resolving...
EDIT: I manually edited my /etc/resolv.conf file, and the result is an impressive speedup in internet navigation, and the solving of the problem linked above. I think that the dns server of my router is teh borken
FINAL EDIT: ok perfect, the dns_servers_eth1 option didn't work as I expected, but the nodns option works perfectly: now /etc/resolv.conf doesn't get overwritten when I start net.eth1, so after maually editing it the problem is basically solved. Thanks again for your help  |
