How to set DNS by command line?

I'm trying to set DNS settings for all devices on my network by command line but I'm not sure how to do it.

I've tried "ping google.com -t" and it says the device is connected to "192.168.0.x" and 192.x and the gateway is "192.1". My router's address is "192. How can I change it? Thanks

If you're using BIND, you can use the command zone to set the dns servers: zone "example.com" in ; };
You have to set the DNS server(s) to your router/DHCP server. You should look at the interface where you have an IP and which is connected to your DHCP. It can be ethernet, wifi or whatever. The command is "sudo /etc/init.d/networking restart".

You should check the interface with "ifconfig". Then you have to add a new DNS entry, for example "8.8" which is Google's DNS.

Then you restart the network with "sudo /etc/init.

How to configure DNS in switch Cisco?

The topic of configuring DNS has a reputation of being somewhat complex, but the following example should be able to get you started.

DNS is available for both BSD and Linux. This example uses BSD DNS.

A couple of DNS servers will be used to manage the network. These servers are called authoritative servers. The servers responsible for managing queries are called resolvers.

The resolvers maintain a cache of recently resolved IP addresses in case a server is not available. The resolver uses the cache to ensure that it returns the correct IP address when asked to resolve an address.

The resolvers can also resolve addresses without consulting the cache. In this example, a Cisco 2960 switch is configured as a resolver and the other endpoints are configured as authoritative servers. To help us better understand the configuration, we will be using the following naming convention: In the following example, the resolvers will be named r1, r2, and r3. We will start with the resolvers. Resolvers. We will create three resolvers. This is just for the sake of the example. There is no need to have three resolvers. You can easily configure more resolvers if you desire.

We need to assign an IP address to each resolver. The addresses assigned are 192.168.15.2 through 192.10.

We will use the subnetmask assigned to the switch, so we do not need to enter the subnet mask. The resolvers will need to know the resolver's address. We will use a static command to set the address of the resolvers.

The resolvers are then assigned the resolver's address. The command is shown below.

After configuring the resolvers, we will need to make sure that they are active. The following commands are used to do so.

We can now verify that the resolvers are all active by using the following commands. The resolvers should be active and the IP addresses assigned are displayed as shown below. Authoritative Servers. An authoritative server is responsible for maintaining the DNS database. An authoritative server can be an external host or a switch. We will use a second switch for the purposes of this example.

What is the command for DNS?

k1l: what is "ip6?

". ipv6. that is a new type of ip v4 or v6. do you mean "IPv6 Address Configuration"? tomreyn: I tried to find some information about this issue, but all I found was someone talking about not being able to find the firmware, not the device :). B0bsF1sh: tomreyn: oh, thanks, I guess I missed that issue then. what is the reason for getting a permission denied when using sudo on crontab? I have created a root user and give it privileges, and used su to run as this user. And still get this error msg coconut: no user running cron needs a root privilege. Thats how ubuntu/linux works coconut: your user needs sudo privs to be able to run a cron job with sudo. This is the default, since sudo can open a security hole.
But if you want to run the crontab command as another user, you need to use su and pass the username to be su -, like so sudo su - . I tryed this as cron user and still same error msg (no idea why). sudo su -m. is that right? I tryed just with su -m and it is ok. but is this right, from my current user account? that is a bad idea.
