Where is the DNS configuration stored in Linux?

Where is the resolv conf file in Linux?

I mean where in Linux machine is the resolv.

Conf? If I use ping mymachine, what should be in resolv.conf, nameserver 1. //mymachine domain myfakedomain? search myfakedomain: options all? A) nameserver 2.2 B) nameserver 1.1 C) domain myfakedomain. D) search myfakedomain. E) option all? What exactly is the right answer here? Where is resolv.conf file? Does anyone know? NOTE: It works fine if I ping my IP, but I thought name server does the job here not ip address. So I wanted to do this.

PS. If you think there's anything other than resolv.conf which plays similar role, please let me know.

The resolv.conf file is now moved from /etc/resolv.conf to /run/resolvconf/resolv.conf and /etc/resolvconf/resolv.d/tail

The resolv.conf file is a configuration file containing a single name server definition for this domain. The path is /etc/resolv. The default location of the domain name server is /etc/resolvconf/resolv.d/tail and /run/resolvconf/resolv. Any file that ends in tail is considered a configuration file. The name server defaults to google.com and 127.0. The nameserver
definitions in resolv.

How to config DNS in Linux?

To configure DNS in Linux, one of the first thing one need to understand is that when you're using network communication in any operating system you need to take some care.

Most of times, these protocols need some form of security to avoid a man-in-the middle attacks, where other devices can see all the data going between two device and also alter them, as we see the majority of this kind of attack right now against Bitcoin community. In this post, I will be telling how to configure a DNS server on our Linux server.

If we talk about IPv4, we need to look for a few settings and make sure that they should be correct, especially the name servers that would be used when requesting an ip address from a server (usually what we are after). For example: Setting Name-Servers and Subnet-Interfaces: We'll need to start up the server by doing this command: sudo service dnsmasq start If your ISP doesn't give you the list of the nameservers it uses, you can ask for a specific one at least, like 8.8 for Google DNS or 208.67.222 for OpenDNS: echo nameserver 208.222 > /etc/resolv.conf Adding the resolvconf package and changing the dns setting: As Linux always starts with a basic configuration that includes a dns, we need to add a special config to tell the resolvconf to include the resolv.conf that we just set. So: sudo apt-get install resolvconf && sudo resolvconf -u You can then edit the /etc/resolv.conf like so: domain example.com search example.com servers 8.8 8.4 Optionally you can add other DNS servers, to do so use: nslookup -query=nameservers 8.4

We could then test the changes on our linux by running: nslookup if we want to see how it goes. Now let's move to how to add a new virtual interface and assign one specific IP to it. So what we'll do is: sudo ifconfig eth0 1.3.
