IP/DNS problem? Ubuntu server+desktop = "no valid net connections found"
location: linuxquestions.com - date: November 25, 2009
i'm a server newbie. i set up a box with ubuntu DNS/Firewall server per the excellent instructions @ http://linuxgazette.net/141/lazar.html. Great article Shane! The ubuntu 9.1 desktop connected to the server says "no valid network connections found" and the live network icon does not appear on the upper right hand corner. But! when i run ethtool eth0 in the terminal I get "Link detected: yes". I can ping the server and other boxes in my network. I cannot ping the internet. I can ping the internet from the DNS server and another server behind the firewall. thank u!
Setting up BIND DNS server on Ubuntu server
location: linuxquestions.com - date: April 12, 2007
I am trying to set up bind DNS server on Ubuntu server edition and this is a pitched battle where I have already spent hours. Well, the issue is that I have to provide BIND DNS server to 4 other clients and it's killing me. Can someone help me on this. Any help will be appreciated. Also, one more thing before setting up BIND DNS, I tried to secure my server by using SHOREWELL firewall and after installing it, it asked me to change the value from 0 to 1. Now, I have changed the value and I am wondering is that already running. Also,
I am not sure how to use iptables, like, I have two ethernet ports eth0 for the internet and eth1 for local network. I want to stop local traffic from accessing the internet. Any ideas. Looking for some help.
Why does basic UBUNTU act as a Router with DNS
location: linuxquestions.com - date: March 1, 2006
I installed ubuntu with apache web server (no modules loaded yet).
I now have one machine with XP and one machine with ubuntu.
Both maachines direct to the same gateway.
If i configure the gateway and the dns-IP on windows XP with the IP of the ubuntu machine , my internet works just fine. Why is that?
Question 2 relates to the fact that I can remove the dns-IP on the ubuntu machine and internet still works fine with just an IP, mask and gateway. On XP that is def not the case, if you remove the dns-IP there, it simply won't work...ever. Why is that?
Hope someone can come up with a decent answer.
DNS problem. Errors on named.conf.local [SOLVED]

I have a problem with my DNS on Ubuntu 9.10
I have a domain called 'linuxer.com' for my local network (just for practise), but the file named.conf.local gave me some errors. I put here the output of the named-checkzone for this file:
Firefox slow dns lookup due to IPv6 in Ubuntu 13.04
location: ubuntuforums.com - date: July 8, 2013
Just installed a fresh copy of Ubuntu 13.04 64 and ran into a very strange problem. Chrome is working fine but Firefox 22 sometimes connects to sites very slow. It can take around 10 seconds before Firefox starts to load something(I can see something like 'connecting to' or look up).
I actually found out how to fix it. Just went to about:config and set network.dns.disableIPv6 to true and Firefox started loading pages very fast
But my question is what's changed since Ubuntu 12.10. In my Ubuntu 12.10 network.dns.disableIPv6 is set to false and Firefox works properly.
localhost as dns server?
location: ubuntuforums.com - date: October 4, 2012
After upgrading my desktop to Ubuntu 12.04 Precise Pangolin I observed that, though I have configured my network connection (cable Ethernet) including a primary DNS server address, which hapens to be my ADSL router to the Internet, I always get my localhost as my DNS server:
~$ nslookup ubuntuforuns.org
~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
Why doesn't it just uses the nameserver I have specified? Can I tunr off this local service? How?
I have missed in 12.04 an utility to enable/disable services at boot time, showing all services installed, as there were in previous Ubuntu versions, such as 10.04.
Thanks for any help.
/etc/resolv.conf vs /etc/network/interfaces DNS?
location: ubuntuforums.com - date: August 7, 2012
What is the point of /etc/resolv.conf if /etc/network/interfaces contains dns-nameservers for each interface that specifies the DNS? Does one override the other?
dhclient dns info from ISP not reaching resolvconf
location: ubuntuforums.com - date: August 5, 2012
I have 12.04 on a gateway machine with 2 interfaces and eth0 gets its IP address and the DNS server IP addresses for the whole LAN from the ISP via the ADSL modem.
I want dhclient from isc-dhcp-client to pass the ISP DNS info to resolvconf to put into the /etc/resolv.conf but this isn't happening.
I know the DNS IPs are coming in from the modem at DHCP time because I put some debugging into /etc/dhcp/dhclient-enter-hooks.d/resolvconf and I can see them coming through. The IP addresses just never make it into /etc/resolv.conf.
Up until now, I've been using another machine as the lan's gateway with debian etch and I want to get it running on this new machine with ubuntu.
I installed the standard ubuntu and it had network-manager installed, so I de-installed that since I'll be using this box with no changes to the network in the long term.
I've dpkg-reconfigured both isc-dhcp-client and resolvconf but still no joy.
My guess is that the issue is either a) due to remo
DNS (bind9) on Ubuntu not working right
location: linuxquestions.com - date: December 14, 2007
I have a server running Ubuntu Edgy (6.10). It stands between the Internet and about 20 Windows desktop machines running Vista, XP, and 2K.
It runs a iptables firewall, bind9, squid, and squidGuard (among other things) and for the most part, it's happy.
However, clients on the network cannot reach the three websites that we own - and are hosting off-site. For some reason it seems to be just those three sites, all the rest of the Web seems to work. The problem is the names are not resolving.
My Ubuntu server's ip address is 192.168.1.1, which is what it assigns as the DNS server to clients that are using DHCP. As I stated - for the most part this works. The server connects to the Internet via ADSL using "pon" and gets two DNS server addresses from the ISP which it puts into its /etc/resolv.conf file.
FROM THE SERVER (via ssh) I can connect to the three "rogue" websites using ping, nslookup, and lynx (there is no GUI on the server).
