How to add DNS in command line?

This is a discussion on ?

Within the Linux Programming forums, part of the Platform Specific Boards category; Is it possible to add a dns server for a programmatic way of adding a dns server like my IP address . Is it possible to add a dns server for a programmatic way of adding a dns server like my IP address in the hosts file, or like I can enter it in the /etc/hosts file?cfg www.whatever.com
So in the file myconfig.cfg, I have a few config variables that I want to use, like my IP address, or the page's DNS that I want to change to, but I also want to use those values in a DNS resolution on that page.

Like if I used wget, it uses my DNS, but if I don't, is there a programmatic way to enter the DNS as an argument and use that for resolving? Like this: I think I already know how to use the resolv.conf, but that's not what I want. I want to have this programmatically so that if I used this program many times, I just add the DNS for each wget, so I don't have to manually edit the file each time.

Also, I need it to be DNS not A or CNAME. This will actually be for all DNS that I need to use in this program. So I'm looking for a way to make a simple command in the linux command line that will do what I want.

What if I used "wget", but not "wget --config-file /path/to/file/myconfig. Does "wget" not use the value in the hosts file, or is there another programmatic way to do it? If you're in windows you should be able to use winsock.

What is the command for DNS in Linux?

DNS is short for Domain Name System.

The DNS server has a small database of hostnames and the IP addresses they correspond to. When you type in "www.google.com" into your browser, it asks the DNS server what "www.com" actually is. The DNS server tells the browser the IP address of "www. If you type that same "www.com" into your browser again, the browser makes a new request to the DNS server and the DNS server returns the same IP address back to the browser.

How to add DNS server on Linux?

How to do it?

I don't know which version of Linux is installed in the system. It is the new virtualized server. I need to add DNS server before the Virtual Machine boot.

Thanks for the answer. I already had installed DNS server (8.8).

There was problem that the name of my computer was changed with some Chinese. So in my host file in my network router I added following line and I works! 168.100.14 www.cxh.com

Thanks for that! Now I have another question how to change the DNS server or ip address of the virtual machine for other applications. I'm using Apache server, php and mysql server. I need to change these values from 192.1 for 192.2 and my local IP for the IP of the virtual machine. How to change that?

How to add DNS entries in Linux?

Let me walk you through this.

You can also find this and some other excellent guides in the official ArchWiki page for DNS: Arch-Linux-DNS, although you will likely. Need to dig out a couple of items that you'll need to put in your local. Syslog config. First, you need to setup your dnsmasq daemon like so. I'm using Fedora 8 so I'll give you the fedora specific way. Sudo nano /etc/dnsmasq.conf Here's my complete config: I have the dnsmasq daemon running on my fedora box at the address 127.0.1
With nothing defined in its dnsmasq.conf file.

Second, you need to add a line to the /etc/rc.conf in addition to your existing line that says something like "rocm" or whatever domain name your system is running. And the reason for doing so is that even if your system doesn't use an. LDAP authentication method, it'll check to see if the domain name is set. In /etc/resolv. The name given for DNS server is defined in either /etc/dnsmasq.conf or in /etc/rc. The one above is the more common /etc/dnsmasq.conf option, and has the effect that dnsmasq will bind to all interfaces rather than just loopback. Note the following: B is a flag. That specifies if dnsmasq binds on any interface. You can use -b or --bind-interfaces. To override that option. For example, to set it to an interface only like so: B lo eth0. You would put that above the other configuration settings. If there is more than one server listed in the "options" argument, then. That will override everything else. For example, if you are using two nameservers that are listed like so, then if both nameservers return. A record with the same A/CNAME record for the same host, then the last one in the list will win. The next paragraph details what happens if you have multiple DNS servers that return. The same A/CNAME record, and how to work around that.
