General :: Change Dns Nameserver - Ubuntu 9.10
Feb 22, 2010When I edit /etc/resolv.conf, it is overwritten right away with the old configuration. How do I really change the nameserver on Ubuntu Server 9.10?

Ubuntu :: ISP Change Blocks Nameserver Access?
Jan 29, 2011I just switched ISPs from a local vendor to Wild Blue. All my Windows boxes adopted automatically. My Ubuntu 10.10 workstation can find no sites, period. My old resolv.conf said:
# Generated by NetworkManager
domain sdc.org (<- my old local ISP)
search sdc.org (<- my old local ISP)
nameserver 192.168.0.1 (<- correct IP V4 address for my router's front end)
This has not changed, and I guess my IP stack is searching for sdc.org domain addresses on WildBlue.net, which don't exist there. After many hours trying to speak with WildBlue Tech Support people, I've decided that domain search questions are beyond their ability to comprehend or discuss. If I could ascertain the domain(s) to search I'd just edit the silly file.
Has anyone else connected with Ubuntu 10.10 on WildBlue?
General :: Host(1) Command Only Uses First Nameserver?
Aug 30, 2011According to the man page, host ought to query "the server or servers listed in /etc/resolv.conf," but it only uses the first entry in that file:

Ubuntu Networking :: Nameserver Not Working
Dec 25, 2010I have a own firewall which is also acting as a nameserver for my own network.

Networking :: How Would One Specify One's Own Nameserver
Aug 19, 2010A server at which I have an account has changed things. The new /etc/resolv.conf fails to resolve a lot of addresses. I can use dig @ with OpenDNS and resolve them successfully, but how do I get apps, such as sendmail, to use a nameserver I specify? It'd be nice if a user could have his own additions to resolv.conf, but I don't see that in the docs, or a way to get sendmail to use a specified nameserver.

Ubuntu Servers :: OpenSSH Reverse Lookup Using /etc/hosts Before Nameserver?
Apr 6, 2010Like many others I'm running into some reverse lookup issues with SSH. Setup is as follows:
localnet setup
myserver - 192.168.0.x
myworkstation - 192.168.0.y
[Code].....
nslookup tests show that my reverse lookup is functioning correctly. However, if I use "myworkstation" to connect to myserver.mydomain.com using an external nameserver SSH says: "Address 84.162.xx.yy maps to myserver.mydomain.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!"
On myserver the /etc/hosts has the internal address for the server which seems the normal way to go to me. Changing this to the servers external address solves the issue.
Apparently a connection originating from myworkstation arrives from/with my external address, and when its reverse is checked by the server it apparently finds its own internal address for that name in /etc/hosts before doing a nameserver query and thus concludes that internaladdress <> externaladdress which gives the error.
Is there any way to have the server check external DNS before /etc/hosts? Another solution would probably be running an internal DNS, so myworkstation doesn't connect through the 'outside'.

Server :: SOA For Nameserver Can't Be Retrieved, Possible Port Or BIND Misconfiguration?
Aug 24, 2010My configuration: CentOS in a VPS environment, I have 2 static IPs at my disposal.I'm having trouble setting up my nameservers. I've registered the nameservers with my registrar and supplied the GLUE records, however my registrar has not yet applied this information into the DNS zone, because my nameservers fail to generate a response on port 53.DNS check says the following about my nameserver address:Checking SOA records for domain. Domain server is not answering to UDP requests on port 53. Possible problems: A firewall is blocking port 53, server is down, server is not running software for handling dns requests.So the only two possibilities I see is that my port 53 is somehow blocked or not properly set to accept and send the correct traffic or that I've misconfigured BIND.
View 2 Replies View RelatedFedora Networking :: Name Resolution: Resolv.conf - NetworkManager - Nameserver
Mar 22, 2009I just installed F10 from a Live download iso on a Sony VAIO laptop with an Intel PRO/Wireless LAN2100 3B Mini PCI Adapter. The linux driver is ipw2100 and functions without problems.
After the install I accepted the update downloads offer and downloaded somewhere around 170 updates. The kernel version is 2.6.27.19-170.2.35.fc10.i686.
I am using a Linksys WRT55AG as a DHCP server. Using NetworkManger it assigns IP addresses without incident.
My problem is that I can't get name resolution to function without manual intervention.
I can ping other wireless nodes on my network and the response to $ dig -q www.yahoo.com is: ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 30153
The /etc/resolv.conf file contains no entry for 'nameserver=' and if I manually edit /etc/resolv.conf, it is overwritten on reboot or restarting the NetworkManager service. I am aware of /etc/sysconfig/networking/profiles/default/resolv.conf.
Additionally, in the var/log/messages file I can see that NetworkManager makes links between /etc/resolv.conf and the default version.
However, after either rebooting or restarting the NetworkManager service, if I manually enter a DNS address 192.168.1.1 (my wireless router) under the DNS tab of the system-config-network 1.5.95 application. This address does not persist after either rebooting or restarting NetworkManager.
If I disable NetworkManager, I can't get the WRT55AG to assign the wilreless adapter an IP address.
So the bottom line and my question is what do I need to do in order to simply boot and have wireless connectivity?
To what file does system-config-network 1.5.95 write the DNS address entered from it's GUI?

May 19, 2010I recently installed Ubuntu 10.04 Netbook Remix on my Gateway LT3103u. I noticed shortly into using it that it has a graphics bug every so often. Especially when I change the background image. Everything will change to a warped mix of colors and pixels. Everything is affected. My mouse, the bar at the top of the screen, text and all. My netbook runs on an AMD Athlon 64-bit processor with ATI Radeon X1270 HyperMemory up to 256MB graphics.

Ubuntu Installation :: Unable To Change BIOS Settings Due To Which Can"t Change Boot Preference?
Mar 24, 2011I currently have a Windows XP OS which i want to dual-boot with Ubuntu Linux 10.10 . I put the disk in the drive and chose the option to install Linux through Windows. But it hangs in the middle. I am also unable to change my BIOS settings due to which i can"t change my boot preference. My first Boot is the HDD. I want to change it to CD-ROM. Any suggestion? I also have another PC where i can boot through the CD...I tried installing there by booting from the CD but i get this error message after seeing the purple Linux screen with the loading dots. "(Process:286):Glib warning**:getpwuid:failed due to unknown user id (0)
P.S.- I am not able to see any options while the boot is going on
Ubuntu :: Change File Permissions To Change Background Screen?
Feb 21, 2010I'm new to Ubuntu Linux but have many years on windows platform. Please can someone help me with how to change the following items.
No.1 I would like to change the HORRIBLE!! YAK!! brown background color behind the word Ubuntu in the start up screen when the machine loads up (before the login). I have located the image file for this which I have found to be: /usr/share/images/xsplash/bg_2560x1600. jpg but the OS says that root is the owner and that I don't have permission to change this. So how can I change this for a color I do like.
No.2 I would also like to change the login dialogue screen style. I know this is possible but again I'm fumbling to see how I can do this. I have tried with the start up manager but every attempt fails, the settings don't take. Once again I suspect permissions are at the bottom of the problem?
No.3 Would like to have a colorful splash screen image on boot up, I've managed to remove the old one (small white 3 ring ubuntu logo on black background) but havent been able to install or replace with a new one. Its been incredibly frustrating, I'm feel sure I'm missing something simple here. Wondering if its permissions yet again?
Anyone who can offer help on any of the above, guidance or advise me would be much appreciated. Please bear in mind that I'm still very much feeling my way with Linux so keep it simple.
