Cloud connections are convenient and encrypted end-to-end. They are highly recommended for connecting to your Raspberry Pi over the internet. You must use the compatible app from RealVNC. By default, these credentials are pi and raspberry. In the command line, run sudo vncpasswd -service. This will prompt you to set a password, and will insert it for you in the right config file for VNC Server running in Service Mode.

You can remotely access apps which use a directly rendered overlay such as; the text console, the Raspberry Pi Camera Module, and others. Please note that direct screen capture is an experimental feature. If your Raspberry Pi is headless i. VNC Server can create a virtual desktop for you, giving you graphical remote access on demand.

Apache is a popular web server application you can install on the Raspberry Pi to allow it to serve web pages. Browse to the default web page either on the Raspberry Pi or from another computer on the network and you should see the following:. This default web page is just an HTML file on the filesystem. In order to edit the file, you need to change its ownership to your own username.

Change the owner of the file the default pi user is assumed here using sudo chown pi: index. You can now try editing this file and then refreshing the browser to see the web page change. Type the following command to install these:. Now save and refresh your browser. You should see "hello world". This is not dynamic but still served by PHP. Try something dynamic:. The instructions assume that you have an existing home network, and that you want to use a Raspberry Pi for the server.

You will also need an additional Raspberry Pi 3 or 4 as a client to be booted. Only one SD Card is needed because the client will be booted from the server after the initial client configuration. Next, enable USB boot mode with the following command:.

Reboot the Raspberry Pi with sudo reboot. The client configuration is almost done. Finally, shut the client Raspberry Pi down with sudo poweroff. Network boot can be enabled on the Raspberry Pi 4 using the raspi-config tool. First, run raspi-config as follows:. Once the Raspberry Pi has rebooted, check that the boot order is now 0xf21 :.

Plug the SD card into the server Raspberry Pi, and then boot the server. Find the settings of your local network. You need to find the address of your router or gateway , which can be done with:. The first address is the IP address of your server Raspberry Pi on the network, and the part after the slash is the network size. Also note the brd broadcast address of the network.

Note down the output of the previous command, which will contain the IP address of the Raspberry Pi and the broadcast address of the network. Finally, note down the address of your DNS server, which is the same address as your gateway. You can find this with:. Configure a static network address on your server Raspberry Pi via the systemd networking, which works as the network handler and DHCP server.

In this example, the gateway address is Additionally, if you have a fallback DNS server, add it there as well. Connect the client Raspberry Pi to your network and power it on. Now you need to modify the dnsmasq configuration to enable DHCP to reply to the device. Where the first address of the dhcp-range line is, use the broadcast address you noted down earlier. You should substitute the IP address here with the IP address you have noted down. Then, add the boot partition back in:.

Good luck! It can take a minute or so for the Raspberry Pi to boot, so be patient. We have created a Python script that is used internally to quickly set up Raspberry Pis that will network boot. There is also a --list option which will print out the IP address of the Raspberry Pi, and a --remove option. We found that we needed to restart the nfs server after using pxetools for the first time.

Do this with:. The bootloader loads the firmware via TFTP and hands over the boot process to the firmware, passing it the details of the network. The kernel boots the rest of the system, loading the root filesystem rootfs via NFS or some other mechanism. To boot via IPv6 you need an updated version of the firmware e. To mount rootfs over the network the IPv4 netboot tutorial suggests using nfsroot.

The first thing the bootloader does is send a router solicitation to get the details of the network. The router responds with an advertisement packet identifying its ethernet address, which the bootloader might need if the TFTP server is on a different network. The router advertisement includes a flag which tells it whether to use stateful managed or stateless unmanaged configuration for its IP address. Stateless configuration means that the device configures its own IP address.

Currently the bootloader generates an address derived from its ethernet MAC address and a network prefix supplied by the router. This involves the device sending a solicitation request to a DHCP server which responds with an advertisement.

The client then requests the address before getting a reply acknowledgement from the server. We send the client architecture type value 0x29 to identify a device. It downloads the firmware binary start4. The firmware is passed the IP address and TFTP server details so it can download the kernel and boot the rest of the system. With IPv4 netboot, nfsroot is used to mount rootfs over the network. It might involve a small RAM file system that can mount the appropriate network location before switching to the proper rootfs contents.

The host test-rpi4 line tells DHCP to give a test device a fixed address. There are sites on the internet that can check this for you or alternatively run the following command. This sends a router solicitation to your router asking for your network details such as the network prefix, router ethernet address and whether to use DHCP for addressing.

You might be able to configure your router for stateful configuration, which means it will use DHCP to obtain an IP address. If the boot uart is enabled you should see something like this from the serial port. The lines starting RX6 indicate that IPv6 is in use. Resolving raspberrypi.

Copy to Clipboard. If the Raspberry Pi is reachable, ping will show its IP address:. PING raspberrypi. On Linux , type hostname -I into a terminal window On macOS , go to System Preferences then Network and select your active network connection to view the IP address On Windows , go to the Control Panel, then under Network and Sharing Center , click View network connections , select your active network connection and click View status of this connection to view the IP address.

Starting Nmap 6. Nmap scan report for Gordons-MBP Nmap scan report for ubuntu Nmap scan report for raspberrypi Nmap done: IP addresses 4 hosts up scanned in 2. Some newer systems expect the interface ID behind the multicast address. Getting the IP address of a Raspberry Pi using your smartphone The Fing app is a free network scanner for smartphones.

You are now connected to the Raspberry Pi remotely, and can execute commands. Keep this on your computer. Copying Files to your Raspberry Pi Copy the file myfile. Copying Files from your Raspberry Pi Copy the file myfile. Copying Multiple Files Copy multiple files by separating them with spaces:. Alternatively, use a wildcard to copy all files matching a particular search with:. Using rsync Edit this on GitHub.

Using rsync over SSH allows you to transfer files to your computer automatically. Linux file and directory permissions mounting and unmounting filesystems. Portmap lockdown optional The files on your NFS are open to anyone on the network. Configuring an NFS Client Now that your server is running, you need to set up any clients to be able to access it.

On the client, we can mount the complete export tree with one command:. Package installation and configuration Install the necessary packages:. Restart services By default, rpcbind only binds to the loopback interface. Security items to consider Aside from the UID issues discussed above, it should be noted that an attacker could potentially masquerade as a machine that is allowed to map the share, which allows them to create arbitrary UIDs to access your files.

Troubleshooting Mounting an NFS share inside an encrypted home directory will only work after you are successfully logged in and your home is decrypted. Create an alternative directory to mount the NFS shares in:. This is quite a convoluted process! Turn on sharing Open the Networking and Sharing Centre by right-clicking on the system tray and selecting it Click on Change advanced sharing settings Select Turn on network discovery Select Turn on file and printer sharing Save changes.

Share the folder You can share any folder you want, but for this example, simply create a folder called share. Create the folder share on your desktop. Right-click on the new folder, and select Properties. Click on the Sharing tab, and then the Advanced Sharing button Select Share this folder ; by default, the share name is the name of the folder Click on the Permissions button For this example, select Everyone and Full Control you can limit access to specific users if required ; click OK when done, then OK again to leave the Advanced Sharing page Click on the Security tab, as we now need to configure the same permissions Select the same settings as the Permissions tab, adding the chosen user if necessary Click OK.

Mount the folder on the Raspberry Pi Mounting in Linux is the process of attaching a folder to a location, so firstly we need that location. You should now be able to view the content of the Windows share on your Raspberry Pi. You may need to try different versions to match up with the server version. Possible values are:.

Sharing a Folder from your Raspberry Pi Firstly, create a folder to share. Now we need to tell Samba to share this folder, using the Samba configuration file. If you are not using a desktop you can install it from the command line as follows:. Ensure VNC is Enabled. Navigate to Interfacing Options. Restart VNC Server. Using Directly Rendered Applications You can remotely access apps which use a directly rendered overlay such as; the text console, the Raspberry Pi Camera Module, and others.

This will also stop any existing connections to this virtual desktop. Installing Apache First, update the available packages by typing the following command into the Terminal:. Regenerate SSH host keys on the client filesystem by chrooting into it:. Enable systemd-networkd and then reboot for the changes to take effect:. Note: comment out port if you want DNS services for systems on the network. Then type the following:.

Using pxetools We have created a Python script that is used internally to quickly set up Raspberry Pis that will network boot. When prompted about saving iptables rules, say no. There are 4 stages to booting a Raspberry Pi computer over the network:. The firmware loads the kernel and command line via TFTP. The bootloader and firmware stages 1 to 3 have been enhanced to support booting over IPv6. How it works To boot via IPv6 you need an updated version of the firmware e. Network addresses The first thing the bootloader does is send a router solicitation to get the details of the network.

Kernel Boot With IPv4 netboot, nfsroot is used to mount rootfs over the network. Alternatively you can use a standalone TFTP server like tftpd-hpa. Soliciting ff ff on eth Hop limit : 64 0x40 Stateful address conf. Debugging Logs and Traces If the boot uart is enabled you should see something like this from the serial port. Finally the bootloader hands over to firmware which should load the kernel. Stateful configuration You can examine network activity with tcpdump. Router sends a response telling the device to use stateful configuration.

TFTP requests are made by the device which should now boot over the network. Stateless configuration Below is an extract of a tcp dump for a stateless non-DHCP network configuration. If you are using a display with your Raspberry Pi and if you boot to the command line instead of the desktop, your IP address should be shown in the last few messages before the login prompt. You will need to note down the IP address of your Raspberry Pi in order to connect to it later.

Using the ifconfig command will display information about the current network status, including the IP address, or you can use hostname -I to display the IP addresses associated with the device. For headless setup, SSH can be enabled by placing a file named ssh , without any extension, onto the boot partition of the SD Card.

When the Raspberry Pi boots, it looks for the ssh file. If it is found, SSH is enabled and the file is deleted. The content of the file does not matter; it could contain text, or nothing at all. When enabling SSH on a Raspberry Pi that may be connected to the internet, you should change the default password to ensure that it remains secure. If you receive a connection timed out error it is likely that you have entered the wrong IP address for the Raspberry Pi.

In the event your Raspberry Pi has taken the IP address of a device to which your computer has connected before even if this was on another network , you may be given a warning and asked to clear the record from your list of known devices. Following this instruction and trying the ssh command again should be successful.

X11 is no longer installed by default on macOS , so you will have to download and install it. You can also send files over SSH using the scp secure copy command. Names like this need to be enclosed in quotes: Copy to Clipboard scp "my file. The SMBv2. Microsoft Windows 7 and Windows Server R2. The SMBv3. Microsoft Windows 8 and Windows Server Microsoft Windows 8. Microsoft Windows 10 and Windows Server Existing connections must be restarted in order for these changes to take effect.

You will come across VNC in there. Make sure you log in with your RealVNC account. Even with a Home license, you will have access to both Cloud and Direct Connections. This is no different from the way you would connect to any other machine running VNC Server. Note that this does not need a logged-in RealVNC account. By default, the account is pi and the password is whatever you have set it to.

You can do other tasks, such as printing or transferring a file, as you normally would in Viewer. Then, search for that machine and connect as usual. You can even create and remote into a virtual desktop. This is very handy if your Raspberry Pi is not connected to a monitor. To this, run the command vncserver on your Raspberry Pi and write down the IP address and display number.

Next, enter it into VNC Viewer and you will be able to connect. Stopping the remote virtual desktop is also easy. To sum it up, remote controlling a Raspberry Pi is just as easy as it is on any other device. You can also find out more detailed information regarding this on our help page.
