Dynamic DHCP update to DNS
location: linuxquestions.com - date: December 31, 2011
Ok, I've thrown everything at this, and I cannot get my Ubuntu 10.04 server to handle dynamic DNS updates from DHCP. The IP lease itself is fine. It's only the DNS update.
Unfortunately, that's worse than where I used to be. In earlier attempts to get it working, I saw error messages about dynamic updates timing out. But now, I get nothing at all.
The last try for dynamic updates gave these messages from the DHCP server's syslog:

IPv6 DNS server using BIND
location: linuxquestions.com - date: July 14, 2009
hi,
I am trying to setup BIND as a DNS server for local IPv6 name resolution within a LAN.
heres the network:
Ubuntu 8.10 running BIND 9.5.0-P2
IPv4 - 192.168.1.8
IPv6 - fe80::a00:27ff:fe56:7f27/64
hostname - dnsserver
Windows XP SP2
IPv4 - 192.168.1.7
IPv6 - fe80::a00:27ff:fea8:81ed%5
hostname - winclient
Both the IPv6 are autoconfigured, while IPv4 addresses are via DHCP.
As long as iam working with IPv4, things work. I forced dnsserver's IPv4 address on winclient's DNS settings.
i can ping winclient and it resolves its IPv4 address. (i get replies from the IPv4 address)
However, as soon as i add dnsserver's IPv6 address as DNS using

Ubuntu dns server SRV records
location: linuxquestions.com - date: April 11, 2011
I am quite interested in one thing. I am trying to code my dns server that when i connect to one of my subdomains it connects not only to an ip adress but to an ip : port adress.
For this i tried using SRV record, but with lack of success.
Dns server specification:
OS Ubuntu server 10.10 and using bind9
I have configured everything so that my subdomains work on an ip address, but i need some of them to work on ip : port too.
in my brfconcept.lv.db file i used: (what i mentioned below isn't the full content of the file)

[SOLVED] DNS lookup failed ubuntu server routing between subnets.
location: linuxquestions.com - date: March 18, 2013
So, I'm routing traffic between subnet .0.0/24 and .1.0/24
From Dev. A, I can get a ping to reach Google using an IP, and can obviously get to the site using the IP, -but- whenever I use the URL, a DNS lookup fails.
I've spoken to someone who thinks that it's something to do with DHCP not passing on DNS information to the leased IP's. And that the Device will be looking for DNS information from the access point, and not the router.

^^ link to a visual example of what I'm talking about.
Basically, ping from Dev all the way through the network to the internet works. But DNS fails.
Any clues as to what might be causing it? I'll do some work on it later and keep you all informed.
Thanks in advance for the replies.

Ubuntu Server manually set DNS
location: linuxquestions.com - date: October 9, 2012
Hey LQ,
Quick question here. I have a ubuntu server up and running with a static IP address, no issues there. The problem I'm having is that whenever I reboot the machine it seems to lose it's DNS settings. I can set the DNS settings manually by doing a sudo nano /etc/resolv.conf and manually adding in "nameserver 192.168.1.254" and then DNS begins to work, but for some reason I lose this configuration upon reboot.
How do I get around this?

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.

Setting up BIND DNS server on Ubuntu server
location: linuxquestions.com - date: April 12, 2007
Hello Friends,
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.
Thanks

Why does basic UBUNTU act as a Router with DNS
location: linuxquestions.com - date: March 1, 2006
Hello,
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.
Thanx
All-in-One
please wait...
