[ubuntu] DNS IP address configuration

linux-howto

http://ubuntuforums.org – Hi, I am using Ubuntu 9.04 (x86-64). My internet connection is not working, i've tried to fix it and the issue seems to be with DNS. I can ping google's IP, but i can ping it URL. I have used the GUI network manager(from Gnome's equivalent of the Windows system tray), to add the DNS IP addresses to the IPv4 wired connection - that hasn't helped. I have checked Code: /etc/resolv.conf and the IP addresses show up there. Code: # Generated by NetworkManager nameserver 208.67.222.222 nameserver 208.67.220.220 I have also checked Code: /etc/dhcp3/dhclient.conf for Code: prepend domain-name-servers 192.168.1.1,208.67.222.222,208.67.220.220; IP address assignment is via DHCP, i need to "force" the DNS Server IP addresses on the ethernet connection. How can this be done? thanks :) (HowTos)

Stories similar to [ubuntu] DNS IP address configuration

I just got FIOS, MI242WR router hooked to my desktop using DHCP over ethernet.

a `ping google.com` succeeds, but it takes ~10 seconds for each ping to succeed.

If I ping the google IP, the ping runs every second, as I would expect.

Here is my resolv.conf:

Code: me@me:~$ cat /etc/resolv.conf # Generated by NetworkManager

Hey all! I installed XBMC live and stupidly skipped the networking configuration. So I manually added the entries for eth0 in /etc/network/interface, which looks like this now:

Code: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).

# The loopback network interface

Resolv.conf Issue 8 weeks 6 days ago

Two things I can think of that overwrite /etc/resolv.conf. The first is dhclient which obtains an IP address from a DHCP server and that can also supply nameserver addresses. The second is NetworkM... [by TrevorH]

Hi...I am new ubuntu user. NM reports that my wireless connection has been established, but I am not able to connect to internet. I am not even able to ping any of my DNS servers...not even to my gateway (192.168.1.1).

My wired connection works fine.

Any help would be appreciated.

I upgraded to 12.10 yesterday and now I can't seem to resolve domain names. Connection Information seems to provide proper DNS server addresses from DHCP, but "ping" and "nslookup" both immediately fail with "unknown host" errors. I have tried external servers (google.com, ubuntu.com) as well as internal network host names, and none work.

BIND on Fedora 10 3 years 47 weeks ago

I've used BIND under Fedora 8 and many previous versions, configuring it with Webmin. I now have a Fedora 10 installation, and am unable to get it working. The Webmin interface seems to have changed a bit, but not enough that I cannot figure out what to do. When I look at my named files, I don't see anything wrong.

Hi All,

I have been plagued by an annoying DNS issue for a long time and was wondering if anyone has any solutions.

Our corporate LAN has a DHCP server which assigns my PC's IPs as well as a domain suffix details. My resolv.conf ends up like this:

# Generated by NetworkManager domain aa.domain.local search aa.domain.local

Issue on resolv.conf 22 weeks 6 days ago

Hi all, :(

I am facing issue while I have updated in resolv.conf, after nework service restart, it was automatically deleted IP from resolv.conf file. Could you please let me know what is the reason resolv.conf deleted any IP which I have manually updated, but it store only my router IP permanently.

Advance thanks for helping..

Hi All,

I'm becoming more and more frustrated with Ubuntu. :( I'm using the Precise Pangolin distro.
