Can I power the Pi via POE? Yes! But you will still need to ensure you isolate the 5v connection between the Raspberry Pi and host PC to prevent backpower issues that can cause instability or damage to either the host PC or the Pi. Do I need a power splitter? Why do I need one? Yes for RPi4, No for Zerow Yes otherwise you could back power the pi and or the target You can get a Y cable from amazon and mod one of the leads - Please see getting start guide You can get a power splitter board from Tindi or PiShop (Links provided below) If you have the v3 HAT - This is built in I can't get the KVM KB to work on my ZeroW! Make sure that you did NOT modify your config.txt file, this is the default: # See /boot/overlays/README for all available options initramfs initramfs-linux.img followkernel hdmi_force_hotplug=1 gpu_mem=64 enable_uart=1 dtoverlay=tc358743,i2c_pins_28_29=1 dtoverlay=disable-bt dtoverlay=dwc2,dr_mode=peripheral Can I use a KB on my ZeroW? Yes but kb/mouse passthrough will not work. Its one or the other Host mode - Comment out dtoverlay=dwc2 Passthrough mode - Uncomment out dtoverlay=dwc2 Can you have the pi-kvm(RPi4) connected along with a monitor? If you have two outputs, you may be able to use screen mirroring from the OS but not BIOS If you have one output or need access from both a local monitor or Pi-KVM at boot time, one of the following options may work: Passthrough HDMI capture devices (sometimes referred to as a loop capture device). The Elgato devices DO NOT WORK! Look for Linux OS support when choosing a device, the expected price range is about $35-$70 US. Depending on your capture device, an HDMI splitter may work but will need what is called an EDID (Extended Device ID) generator, the monitor and capture device both generate EDID so the splitter must produce its own separate EDID for the host. Look for HDMI splitters - although there have been reports that these are not stable Please use the search function in Discord, some users have has sucess in getting this to work but your mileage may vary The better solution is to capture the stream in a dir and then use VLC to stream to that capture on another computer. This will result in fps loss. Wouldn't it be good to have different hostnames for your multitude of pi-kvms? Enter read write mode of the PiKVM by executing the `rw` command Execute: `hostnamectl set-hostname yournewhostname.domain` Optional: Edit `/etc/kvmd/meta.yaml` to alter the displayed hostname in the web UI Reboot the pikvm I can't make edits?!?!? Did you issue a `rw` before updating/editing? In the Web Terminal, how do I get root? Type `su -` Put `root` for the password Why are you using Arch Linux? The developer was more familiar with Arch Linux so this was chosen as the base operating system. As a Linux distribution, it has more in common than not with other distributions. As an appliance, users are not expected to interact with the host operating system often, if at all. There are some distribution-specific differences, by default networking is done using either systemd-networkd or netctl but NetworkManager can be used as a replacement if one prefers. Is Pi-KVM an OS? No, this is merely riding on top of an existing OS I want to do something not related to Pi-KVM It's recommended that you review Arch documents related to what you want to do, while there are several folks in discord who can help, there is no obligation...they do it for the feels. So if you don't get an answer within the time frame you are looking for, it's advised you start google searching for what you want. Can this be used in any other distro’s like Rasbian? Not at this time, maybe in the future My Pi keeps disconnecting from my wireless! What do I do? Edit "/etc/conf.d/wireless-regdom" and look for your region and uncomment it. Example: WIRELESS_REGDOM="US" I want a static IP!! You can configure systemd-networkd for a static address for ethernet NIC. Config file is /etc/systemd/network/eth0.network For wireless adapter, config file is /etc/netctl/wlan0- See pikvm/wifi_config.md at master · pikvm/pikvm · GitHub for details on how to get basic wireless config with DHCP going. Afterwards, you’ll need to edit the /etc/netctl/wlan0- file changing the IP=dhcp line with the following lines updated to reflect your network: IP=static Address=('192.168.X.XXX/24') Gateway=('192.168.X.X') DNS=("192.168.X.X 1.0.0.1 1.1.1.1") You can also reserve the IP in your dhcp server (Quicker) Why do I keep getting a different IP? The most likely reason is piKVM root FS is RO, so it cannot cache its lease and ask for the same one next time DHCP servers look at a variety of things to determine if the same host is asking for the same IP, some look at MAC addresses, some look at the session string Add to, /etc/systemd/network/eth0.network [DHCP] ClientIdentifier=mac Help! I ran out of room! What now? You’ve cached package updates you no longer need. Enter read/write mode by executing rw as root Execute the following as root to clear the package cache rm -rf /var/cache/pacman/pkg/* Exit read/write mode by executing ro as root You can also use gparted to resize partitions without losing data, although Can you connect a camera to this and still make pikvm functional? Yes, any cheapo webcam can be used in place of the usb dongle, please use the usb image I have a question that is not answered here!! Now what? Please look at all pins on Discord Please look in #news on Discord I want the v3 hat!! Where do I get it?? At this time it is not available, due to the current pandemic the factories are running at a much slower rate HELP!! I can't find the IP on the ZeroW Open a browser and type: pikvm, still doesnt work? Use the FING mobile app to scan your network, its free Install Angry IP scanner, tools/preferences/Display results in the results list/Select Alive hosts, modify IP range, hit start Using FF, navigate to https://pikvm Open web terminal and go to root, rw then nano /etc/issue add ‘IP: \4’ Once you reboot, you will now see the IP in the upper right HELP!! Something isn't working!! What was the last thing or most recent thing you did? Did you undo it? Did you hook this to anything else? If not why not? Did you try different cables? Troubleshooting Did you connect a monitor to the target? Does it work? Did you connect the PIKVM to the target directly? Does it work? Common Commands for troubleshooting Pi-KVM journalctl -u kvmd journalctl -u kvmd-vnc journalctl -u kvmd-ipmi Common ARCH commands search - pacman -Ss `the thing` install - pacman -S `the thing` Common wifi commands iwconfig manipulate the basic wireless parameters iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys… iwspy allow to get per node link quality iwpriv allow to manipulate the Wireless Extensions specific to a driver (private) Some examples iw dev wlan0 scan | egrep "signal:|SSID:" | sed -e "s/\tsignal: //" -e "s/\tSSID: //" | awk '{ORS = (NR % 2 == 0)?
