What is my Hostname in Linux?

For most of you, your hostname in Linux is going to be the same as your username. This article will help you figure out your hostname in Linux, and it should be a relatively short article. If this article looks familiar, it’s because it existed at the old site, but with far less information.

Let’s start at the beginning, by learning what a hostname is.

A hostname is generally meant to be a human-readable way to identify a computer. Yes, the computer is truly identified by the associated IP address, but the hostname resolves to that computer. It is meant to be easily remembered instead of having to remember a bunch of IP addresses. Without it, the web (and your own local networks) would be more difficult to navagate.

In many instances, it’s a FQDN (Fully Qualified Domain Name), such as a domain name like linux-tips.us. However, this site doesn’t have a dedicated IP address, so it’s known by a virtual hostname as a FQDN. If the site had been constructed differently, you’d be able to access it with the IP address. For example, https://172.217.10.14 will take you to Google (after some warnings).

So, your hostname in Linux isn’t always going to be the same as your username. For most of the readers here on L-T.us, it will be. You probably don’t really need to worry a whole lot about things like virtual hosts and stuff like that. But, even as a home user, you can make use of this information.

How is it useful? Well, if I want to SSH into my MSI laptop, I don’t have to use the IP address. Not only that, if the IP address changes then I don’t need to look it up. I just connect with something like:

How to get the computer name (not its hostname)?

All the results of my searches end up having something to do with hostname or uname -n . I looked up the manual for both, looking for sneaky options, but no luck. I am trying to find an equivalent of OSX’s scutil —get ComputerName on Linux systems. On Mac OS X, the computer name is used as a human-readable identifier for the computer; it’s shown in various management screens (e.g. on inventory management, Bonjour-based remote access, . ) and serves as the default hostname (after filtering to handle spaces etc.).

I might be wrong, but defining the name of the computer as its network name means that it doesn’t have a fixed name, right? When you install a Linux or OSX on a machine, you usually choose a name for that computer (which is the default network name I assume). For example my laptop might be named «FooBar» but when I connect to a network at work I get a hostname such as «machine42.work.localnetwork».

@Sh3ljohn what purpose does computername is osx serve? I don’t think there’s any equivalent in linux system.

Did you give some name other than hostname when installing that computer? Try searching for that name in /etc: grep -ri ‘name’ /etc

@Bibek_G I would like to use this to identify the machine on which I am running from a software of mine. UUID is insufficient because there might be several OS’s installed on the same disk which in turn run on the same machine.

The closest equivalent to a human-readable (and human-chosen) name for any computer running Linux is the default hostname stored in /etc/hostname . On some (not all) Linux distributions, this name is entered during installation as the computee’s name (but with network hostname constraints, unlike macOS’s computer name). This can be namespaced, i.e. each UTS namespace can have a different hostname.

Systems running systemd distinguish three different hostnames, including a “pretty” human-readable name which is supposed to be descriptive in a similar fashion to macOS’s computer name; this can be set and retrieved using hostnamectl ’s —pretty option. The other two hostnames are the static hostname, which is the default hostname described above, and the transient hostname which reflects the current network configuration.

Systemd also supports a chassis type (e.g. “tablet”) and an icon for the host; see systemd-hostnamed.service .

But this file is often used to set hostname and uname -n , and @Sh3ljohn explicitly wanted to avoid the output of those two commands.
