First power on¶
For v2 DIY owners, please follow this first
For v3 HAT OR Pre-Assembled Users, please follow this first For both to work and display a video, your target system needs to be configured for the following: 1920x1080p50Hz (In some rare instances, try 30hz) 1600x1200p60Hz 1280x720p60Hz
Optional setting up Wi-Fi
Please read the following caveats
- There is nothing more reliable than wired Ethernet, so it's better to use the cable. But who are we to stop you... :)
- Adding FIRSTBOOT=1 or FIRSTBOOT-1 will erase the msd partition, if used afterwords as a means of switching wifi networks, do not include this option. Instead, use different supplicant files for each wifi SSID, mv files to the supplicant dir as needed and reboot.
pikvm.txtwill be removed once its been used. You will need to recreate it again if you did not provide the correct info
If you want to connect PiKVM to a Wi-Fi network, you need to tell the device ESSID and password before first boot.
To do this, mount the first partition of the memory card (FAT32) and edit or make the
pikvm.txt file there.
Do not remove line
FIRST_BOOT-1 for first time booting, just add your wifi settings like this:
FIRSTBOOT=1 WIFI_ESSID="mynet" WIFI_PASSWD="p@s$$w0rd"
There is a possibility that, in countries that support CH13, the device will not connect. You will need to configure your router to disable channels 12-14 or disable Auto scan mode so it will connect.
Save, unmount and follow the next step.
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 will perform the necessary operations on the memory card.
Getting access to PiKVM¶
By default, PiKVM receives a dynamic IP address via DHCP.
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
- Linux, MacOS, Windows: Download and run Angry IP Scanner.
- Windows PowerShell: Use command
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.
Access to PiKVM Web Interface
In MOST networks you should be able to reach PiKVM via any browser with the URL
https://pikvm/. Google Chrome (Chromium), Firefox and Safari work best with 0 extensions enabled, if one works but the others do not, this is a browser/extension issue. Its advised you use Private window or Incog mode. Microsoft Edge and Internet Explorer are not supported.
The default user is
admin and the password is also
admin. 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.
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:
- Windows: Use PuTTY for this.
root password is
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 benifit from performing the below actions. These are the instructions:
rw pacman -Syu reboot
✮ ✮ ✮ CHANGE THE PASSWORDS! ✮ ✮ ✮
PiKVM comes with the following default passwords:
- Linux admin (SSH, etc.): user
- PiKVM Web Interface: user
These are two separate entities with independent accounts. To change passwords, you will need to use the terminal (read below) access via SSH or Web Terminal. If you are using the Web Terminal, use the
su - command to get root access (enter the root user password).
# rw # passwd root # kvmd-htpasswd set admin # ro
# kvmd-htpasswd set <user> # Sets a new user # kvmd-htpasswd del <user> # Removes/deletes a user
Most of the PiKVM settings are done through configuration files. All configuration changes must be made from under the
root user (that is, the administrator).
Obtaining root access
- If you have logged in via SSH, then most likely you are already
- To get
rootin 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.
Enabling write mode
- To enable write-mode, run command
- To disable it, run command
- If you receive the message "Device is busy", perform
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
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/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.
/etc/kvmd/meta.yaml file you can specify some information regarding the host that this PiKVM manages.
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
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.
Sections under the same keys should be merged
