11/13/2023 0 Comments Debian change hostnameIn this tutorial, we learned how we can change the hostname of a Debian system by editing the etc/hostname file. It should display the new hostname you set. You can verify the changes by opening a terminal and running the following command: hostname You can do this by running the following command: sudo rebootĪfter the system restarts, it should have the new hostname you set. To apply the new hostname, you need to restart your system. Update the hostname part in that line to match the new hostname you set in the /etc/hostname file. In the file, you'll see a line starting with 127.0.1.1. Different commands are used to change the hostname using the terminal which are explained in the next section. Method 1: Using the Command Utilities To change the hostname by executing some commands, a terminal of Debian 12 can be used. Open it with the text editor using the following command: sudo nano /etc/hosts Using the GUI method Changing Hostname by all above methods has been explained in detail. Next, you need to update the /etc/hosts file. In nano, you can do this by pressing Ctrl+O to write the file and then Ctrl+X to exit. For example, if you want to change the hostname to "myhostname", your /etc/hostname file should contain only the following: myhostname Replace it with the new hostname you want to set. In the editor, you'll see the current hostname. For example, to use nano, run the following command: sudo nano /etc/hostname Use a text editor like nano or vim to open the file. In the terminal, you need to edit the /etc/hostname file. You can do this by clicking on the "Activities" button in the top-left corner, searching for "Terminal," and selecting the terminal application. To change the hostname in Debian 11, you can follow these steps: 3.1 Overview 3.2 Ensure that the new hostname can be resolved using /etc/hosts 3.3 Alter the file /etc/hostname to contain the new hostname 3.4 Activate the. It is used to distinguish one machine from another in a networked environment. So my conclusion is that all I was doing above was correct, but somehow it mystically take a great amount of time for my Ubuntu 17.04 to realized it.Īnyway, I'll accept Giacomo1968's answer as he has something new in how to use sysctl and hostname is a label or identifier assigned to a computer or device on a network. $ uptimeĢ1:33:36 up 2 days, 1:36, 5 users, load average: 0.22, 0.43, 0.29Īnd the above (network) delay to connecting to my sendmail server is gone too. Moreover, even when everything is working, my sysctl kernel.domainname is still reporting (none). So now it is working, and I still do not know why it is working now, and why it didn't work before. I should have traced to a new file, but I didn't. I didn't do anything, except I traced again the hostname -f. Today, the hostname -f, hostname -d & dnsdomainname are all working fine now. I can put it here if anyone interested.Īs a consequence, there is an extensive (network) delay to start and stop my sendmail server. I did a trace on hostname -f, but can't figure any problem out of the log. Here are details of the machine I want to access using its hostname: hostname hostname cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 hostname It's a default Debian 6 (Squeeze) install, so I didn't fiddle with anything yet.I didn't put my host name (coral) in /etc/hosts because I don't want my host name to resolve to 127.0.0.1 but to real IP instead, which I obtained from my DNS server. Using alias the host name in /etc/hosts to specific the FQDN seems to be the correct answer, however, I've already done that see the above localhost.my. entry.I've rebooted several times, and my domainname is still blank now. Display the current hostname for Debian Linux Change the Hostname use hostnamectl set-hostname Verify the Change Changing Debian host names remotely using. I have never been able to fully understand how to change Linux hostname and domainname, and now it comes back and bites me again - my Linux domainname is blank ( domainname gives (none)) and I just cannot change it back: $ hostnameġ27.0.0.1 localhost.my. localhost
