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:
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**.
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.*
Most of the PiKVM settings are done through configuration files. All configuration changes must be made from under the `root` user (i.e. the administrator).
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`.
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](https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html)
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.
