# Configuring Hostname

Configuring a custom hostname is important in many environments. This is easily done by editing the file

```plaintext
/opt/fmadio/etc/hostname
```

## Step 1) Confirm current hosname

The default hostname looks similar to below

```plaintext
fmadio@fmadio200v4-636:/opt/fmadio/etc$ cat hostname
fmadio200v4-636
fmadio@fmadio200v4-636:/opt/fmadio/etc$
```

## Step 2) Edit the hostname

Edit the file to update the hostname as required

```plaintext
sudo vi /opt/fmadio/etc/hostname
```

OR use nano

```plaintext
sudo nano /opt/fmadio/etc/hostname
```

## Step 3) Reboot to ensure hostname is persistent

Reboot the system to ensure the name change is persistent

```plaintext
sudo reboot
```

NOTE: /etc/hostname is volatile and will not be changed between reboots. It requires updating of /opt/fmadio/etc/hostname
