If you are logged in with another use, you can change it directly and recover access to this session. Another option could be to change the default username on your Raspberry Pi. A similar way is to use the root user directly. What you can also do, is removing the password requirement on another session.

As reminder, here is how to log in as root on Raspberry Pi. Unfortunately, there is no other way. As the root user is not enabled by default, you can start in single user mode or anything like that which I use on Linux from time to time. I'm the lead author and owner of RaspberryTips.

It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I have recently changed my Raspberry Pi login password from "raspberry" to something more specific and now when I try to connect the VNC I get an "Authentication Failure" message.

Use the command vncpasswd man page. If you can log into the Pi using an actual monitor, then get X running startx , open the VNC Server app, go to Options, then Users and Permissions, click on Password, and confirm a new password to use.

You can share any folder you want, but for this example, simply create a folder called share. 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.

Select the same settings as the Permissions tab, adding the chosen user if necessary. Select Custom and set the required permissions, and click OK , then Finish. Mounting in Linux is the process of attaching a folder to a location, so firstly we need that location. Now, we need to mount the remote folder to that location. The remote folder is the host name or IP address of the Windows PC, and the share name used when sharing it.

We also need to provide the Windows username that will be used to access the remote machine. In order to fix this a version entry needs to be added to the mount command. By default Raspberry Pi OS will only use versions 2. Older devices, including some NAS, may require version 1. Firstly, create a folder to share. This example creates a folder called shared in the home folder of the current user, and assumes the current user is pi.

Now we need to tell Samba that there is a pi user when accessing that folder. When asked, enter the password of the pi user - this can be the default password, but that is well known and should be changed for better security. In the same file, find the workgroup line, and if necessary, change it to the name of the workgroup of your local Windows network.

That should be enough to share the folder. On your Windows device, when you browse the network, the folder should appear and you should be able to connect to it. Sometimes it is not convenient to work directly on the Raspberry Pi.

Maybe you would like to work on it from another device by remote control. VNC is a graphical desktop sharing system that allows you to remotely control the desktop interface of one computer running VNC Server from another computer or mobile device running VNC Viewer. You will see the desktop of the Raspberry Pi inside a window on your computer or mobile device. You must enable VNC Server before you can use it. By default, VNC Server gives you remote access to the graphical desktop that is running on your Raspberry Pi, as though you were sitting in front of it.

However, you can also use VNC Server to gain graphical remote access to your Raspberry Pi if it is headless or not running a graphical desktop. For more information on this, see Creating a virtual desktop , further below. You can enable VNC Server at the command line using raspi-config :. There are two ways to connect to your Raspberry Pi. You can use either or both, depending on what works best for you. For example, this might be a wired or wireless network at home, at school, or in the office.

For best results, use the compatible app from RealVNC. 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.
