First steps

!!! note "Before this guide"

* PiKVM V4 device: please follow this [first](v4.md)
* PiKVM V3 HAT/Pre-Assembled: follow [this](v3.md)
* DIY V0-V2: follow [this](https://github.com/pikvm/pikvm)

First power on

Optional: setting up Wi-Fi before booting.
There is nothing more reliable than wired Ethernet, so it's better to use a cable.
Power up the device.
Do not turn off the device until it's fully booted for the first time.
After turning on the power, PiKVM OS will generate unique SSH keys and certificates and perform all necessary operations on the memory card.

Getting access to PiKVM

By default, PiKVM receives a dynamic IP address via DHCP. V3+ devices show IP on the built-in display. If you don't have a display, use the tips below:

??? example "Finding PiKVM in the network" To determine the IP address of your PiKVM, use one of the following methods:

* **Common way:** Open the web interface of your router and find the list of issued IP addresses there. It depends on the router model.
* **Linux-only:** Use command `arp-scan --localnet`.
* **Linux, MacOS, Windows:** Download and run [Angry IP Scanner](https://angryip.org).
* **Windows PowerShell:** Use command `arp -a`.

In order to find your RaspberryPi using the arp commands, you need to look for the following MAC Address's: B827EB, DCA632 or E45F01

For future examples, let's assume that your PiKVM has received the address 192.168.0.100, which you have successfully detected using the instructions above. Then your device was assigned a hostname: pikvm.

??? example "Access to PiKVM Web Interface" In most networks you should be able to reach PiKVM via any browser with the URL https://192.168.0.100/ OR https://pikvm/. Google Chrome (Chromium), Firefox and Safari work best with 0 extensions enabled, if one works but the other does not, this might be a browser/extension issue. Its advised you use private window or incognito mode. Internet Explorer and the pre-Chromium version of Microsoft Edge are not supported.

**The default user is `admin`, the password is also `admin`, and no 2FA code.** After logging in, you will get access to the menu with the main functions. Using the Web Terminal, you can change system settings and passwords.

*The latest versions of Chrome on Mac OS do not allow access to the page with a self-signed certificate, which is used in PiKVM by default. You can proceed by typing `thisisunsafe` and Chrome will then load the page.*

??? example "Access to PiKVM via SSH" SSH is the most common remote access method in the Linux world. PiKVM is accessible via SSH. This method is used to manage the device:

* **Linux, MacOS:** Open any terminal application and run: `ssh root@192.168.0.100` or `ssh root@pikvm`.
* **Windows:** Use [PuTTY](https://www.putty.org/) for this.

**The default `root` password is `root`.**

??? example "OPTIONAL: Update PiKVM software" This part is not nessessary for a working OOB experience and should only be performed if you are physically at the PiKVM to recover it, you however, may benefit from performing the below actions. These are the instructions:

```
rw
pacman -Syu
reboot
```

{!_passwd.md!}

Configuring PiKVM

Most of the PiKVM settings are done through configuration files. All configuration changes must be made from under the root user (= the administrator).

!!! tip "Obtaining root access" * If you have logged in via SSH, then most likely you are already root. * To get root in the Web Terminal, use command su - and enter the root password.

The PiKVM memory card is mounted in read-only mode. It protects the filesystem from damage in case of sudden power outage. To edit any files and make changes, it is necessary to remount the file system to the read-write mode.

!!! tip "Enabling write mode" * To enable write-mode, run command rw (under root). * To disable it, run command ro. * If you receive the message "Device is busy", perform reboot.

In this handbook, you will often find instructions for editing configuration files. The simplest and most beginner-friendly text editor is nano, but you can also use vim.

??? example "Editing files in the Web Terminal" $ su - # rw # nano /etc/kvmd/override.yaml # ro

Structure of configuration files

Most of the PiKVM configuration files are located in the /etc/kvmd directory.

The /etc/kvmd/main.yaml file defines the platform config and you should never edit it. To redefine system parameters use the file /etc/kvmd/override.yaml. All other files that are also not recommended for editing have read-only permissions.

In the /etc/kvmd/meta.yaml file you can specify some information regarding the host that this PiKVM manages.

!!! tip A complete list of all parameters can be viewed using the kvmd -m command.

Files with the suffix *.yaml uses the YAML syntax and describes a parameter tree with key-value pairs of different types. To define the parameters within one section, an indent of 4 spaces is used. Comments starts with the # symbol.

!!! warning "Only 4 spaces should be used for indentation" Be careful when editing YAML and follow this rule. Invalid indentation or tabs instead of spaces will cause an error when starting the services.

??? example "Sections under the same keys should be merged" * Wrong:

    ```yaml
    kvmd:
        gpio:
            drivers: ...
    kvmd:
        gpio:
            scheme: ...
    ```

* **Correct:**

    ```yaml
    kvmd:
        gpio:
            drivers: ...
            scheme: ...
    ```
