Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It only takes a minute to sign up. As you might have guessed from the title, I would like to know if it is possible to change a RasPis hostname from the config. I'm making a lot of SDs from a custom image, and obviously the hostnames collide when booting they are used from other apps in the network. It is not possible to set the device hostname through config.
A full list of commands can be found on the Raspberry Pi Foundation's website. You mention that you're creating a custom image. It does require a reboot assuming the RPi is currently runningbut so does changing anything in config. If you really want to get around the restart thing, it's possible, but can cause some issues. Once that's set, restart the network service with sudo service network restart.
Now, if you run hostname you should see your new hostname as active.
This change is not permanent. Okay, from your comments on the other answer, it looks like you want to change the hostname of Raspberry Pi image without actually booting it. This should be trivial. Where image. Look under the start column for the second Linux ext4 partition to find the block it starts on. Substitute that into the command below. Note that this won't change after this process, so you can change the hostname, send off the image, and then change it again, without needing to run fdisk and use a new value.
Get rid of the default and type in the hostname you want, and then hit Ctrl-x, then y, and then enter. We can now unmount the image like this. Using dd to load the image onto the SD card and booting the card in a Pi will set the Pi's hostname to the one you specified above. To automate this process and change the hostname of an image quickly between dd's, one could write a bash script:. Sign up to join this community.

Open a Terminal under Raspbian or connect in SSH to your Raspberry and then open the configuration of the interfaces file. Modify the file by adjusting the following configuration to your needs. Here is an example of configuration it will adapt to your configuration.
This configuration works fine if you plug your Raspberry Pi on another computer that is sharing its internet connection. For example, I use my Mac Mini as internet bridge time to update distribution Raspbian for images too old home automation software that do not support the WiFi of the ft3. Raspbian assigns a domain name to the Raspberry.
Default is raspberrypi. For example, SSH simply enter. Similarly if you do home automation, you can access your Domoticz box from a browser by entering the URL.
Now, we would like to be able to change the default domain name. Why not give the Raspberry name of the home automation for example box. Replace raspberrypi by domoticz for example or any other name without space, special characters or accented characters.
This is great and I can now easily access my rpi from my computer but what about if I am using my rpi as a hotspot. I want to be able to type examplename. I can type Participate in the development by downloading the test version from the Apple Store or the Google Play Store. You are already over ! Thank you! To learn more about infomaniak's commitments to the environment.You have probably already noticed that after the system installation, all Raspberry Pi on Raspbian have the same name In this post, I will explain to you what it is and how to change it as you want.

How to set a new hostname on Raspberry Pi? On a network, any device will use a few identifiers like the IP address or MAC address They also have a label, mainly to help us to identify which device has which IP the hostname. For example, when you do a network scan, it will generally give you the IP and MAC address but also a name the hostname :.
You can set almost what you want as a hostname, but you need to avoid using the same hostname on several devices Valid host names are between 1 and 63 characters, with only letters a-zdigits and hyphen. The second solution is to use raspi-config You probably already know this tool, you can use it to change many things in your Raspberry Pi configuration.
The last option I want to show you is to use the Raspberry Pi Configuration Tool on Raspbian Desktop This is probably the easiest one if you are on this Raspbian version. The wizard will change it for you. I hope this post was useful for you If you have any remaining question or a suggestion, feel free to post a comment below.

Try using hostnamectl. This command, which is available on pretty much every Linux distro including Raspbian:. If a static hostname is set, and is valid something other than localhostthen the transient hostname is not used. There are actually three hostnames: Static, transient, and "pretty"; the latter is a string that can contain any characters including those that can't be used in RFC hostnames.
The command:. Note in the above screenshot that if the pretty hostname is specified and the static hostname wasn't then the pretty name will be made RFC compliant by replacing uppercase with lowercase and spaces with underscores, and by omitting special characters before it's copied into the static hostname. You can specifically set any of the three hostnames, for example:. Here's an example of having set the pretty hostname to "Barkometer" which is then transformed to "barkometer" for the static hostname then having set the transient hostname to something different, for example, "Test":.
Perhaps it's a bug but the transient hostname can be set to a string that isn't RFC complaint and which is then used when the hostname is required. Finally, under Raspbian, specifying an empty string "" without specifying a hostname:. Drop me a line or comment below then follow me on Twitter and Facebook.

Read on as we demonstrate by assigning an easy to remember name to our Raspberry Pi. Most likely your home network uses DHCP IP assignments, which means that each time a device leaves the network and returns a new IP address is assigned to it. Even if you set a static IP for a frequently used device e. Further, if you ever need to change the number for any reason you would have to remember a brand new one in its place.
Why bother with memorizing IP strings when you can give you local devices easy to remember names like raspberrypi. Now, some of you especially those of you with a more intimate knowledge of DNS, domain naming, and other network address structures might be wondering what the catch is. For example. That could, however, change though the chance is remote in the future if.
Conversely, the. It will never be configured as a FQDN and as such your custom local names will never conflict with existing external addresses e. Confusingly, there are actually two implementations of mDNS floating around, one by Apple and one by Microsoft. The mDNS implementation created by Apple is what undergirds their popular Bonjour local network discovery service. The Microsoft implementation was never widely adopted thanks to its failure to adhere to various standards and a security risk related to which domains could be captured for local use.
The first order of business is to either pull up the terminal on your Pi or connect into the remote terminal if you have a headless machine via SSH.
Once at the terminal, take a moment to update and upgrade apt-get. Enter the following command at the prompt:. The particular machine we used for this test is the same Raspberry Pi we turned into an ambient weather indicator, and then later changed the local hostnameso when we go to look for the newly minted.

Is it possible to change the hostname of my Raspberry Pi permanently, but also have the change take effect without rebooting? Yes, it is possible using the following steps. Replace "mynewhostname" with whatever hostname you are changing to. Replace the line This is the trick to skip rebooting, issue the following command to change the currently used hostname:.

This is the trick to skip rebooting, issue the following command to change the currently used hostname: sudo hostnamectl set-hostname "mynewhostname" 4 Restart the mDNS daemon To be able to use mynewhostname.
If you're logged in and your bash prompt includes the host name, the prompt is set when bash starts. So using hostnamectl won't change your prompt.
To check the new prompt, enter "bash" to start a subordinate bash process". Or you can log out and log in. I just wrote an almost identical script. Even without the "without rebooting" requirement, this is a glaring omission from Raspbian! I just wanted to programmatically set the hostname on multiple devices.
