    Use Third Party Products: 1. This service is developed to assign IP addresses to the devices connected to the network. Ideally, this service is managed by your home router. Bear in mind; this address is dynamic. The router assigns a new address once after lease period elapsed. This nature of DHCP may force you to set up a remote connection each time your Pi gets a new address.

    And, you may lose control over your Pi if you are outdoors. This may create a hassle for you. To avoid this mess, it is better to configure Pi with a static IP address to make your settings more stable. This configuration allows the router to never expire the lease and keep the IP static.

    You may need to manually track to avoid accidentally assigning the same IP address with more than one device on the network. Follow these steps to configure a static IP address on the Raspberry Pi. Reboot the Pi so that all changes can take effect. All right, now we are set to go. There are several ways to connect Pi remotely.

    We are going to tell you the five most commonly used methods in this article. The only limitations are that you should have access to the network to which the Pi is connected and this gives access to the only command-line interface.

    Make sure SSH is enabled on the Pi. Connecting from Linux: There is nothing additionally required from a Linux to connect. Up to my knowledge, a command-line SSH client is loaded with all Linux distributions. If taking Raspberry Pi as an example. SSH supports plenty of different options to login. We recommend to check out the SSH protocol for more information. Install and run the Putty, Supply the hostname or IP address of the Pi with 22 in the port number field.

    This session asks you to enter the username and password. After a successful login, it gives you a command-line prompt.

    Most users want to use the GUI desktop over the network. There is a simple solution for this, XRDP. It is an open-source remote desktop protocol which allows you to connect remote desktop from any platform. This is a cross-platform protocol works on standard port. Just you need to allow this port on the system firewall.

    One downside is it can be used only inside the network. Open the terminal if you have direct access. Time needed: 5 minutes. You can install the application by issuing the below command. It may take a couple of minutes depending on your system and internet speed. It works only on the GUI desktop environment. This is a very cool application. Credentials could be supplied later as well.

    There is a verity of products available on the market. Few products are free and few are commercial. This allows you to connect Pi not only within the network but also over the internet. RealVNC gives users the freedom to connect from anywhere. This flexibility makes this option more prominent than others. To keep this post simple we have created another dedicated blog post to show you how to set up the VNC on the Raspberry Pi.

    Open VPN: The last piece of our remote connectivity puzzle is how to access our Pi when you are out of your home. If your router provides VPN services on its own than you might consider that option. To shorten this post we have created another dedicated blog post to show you how to set up the Open VPN on the Raspberry Pi. There are a wide set of tools available in the market to connect Pi remotely. We recommend not to leave this option unchecked. My favourite tools are chrome desktop.

    I love this because of its simplicity and light weight nature. All you need to have is a chrome browser with signed into it. The procedure is as simple as a couple of clicks. To access the Pi over the internet, launch the chrome browser on the machine from where you want to access your Pi and visit the same page and select Remote Access. There you are going to see your Pi as an icon, click to connect. Thank you for reading this article. Please visit the below links to read more such interesting articles.

    Create a wifi hotspot with Raspberry Pi 3 and Fedora

    In addition to this error message, red colored stars appear. Behind it runs a counter that counts about 1 minute and 30 seconds down. Nothing happens until then, which increases the total boot time of the Raspberry Pi by this time.

    The reason why this does not continue here is that one of the network interfaces still has no connection to the network. The problem also occurs when there is a network configuration but there is no network connection. You have to connect Raspberry Pi to the network.

    Either by cable or WiFi. The fastest way is by cable, because the interface is then ready at boot time. For wifi, it can take longer, because the interface must first authenticate against the wifi access point.

    If the correct DNS server is then entered manually, the file is overwritten after a reboot. Making manual changes has only temporary effects. Most of the changes are gone after a reboot. Sometimes they also last for hours or days. Which is the exception. There are services that configure this file. The question now is, what do you do when you do a static configuration? Then such services are counterproductive.

    The first thing to do is find out which service spits you into the soup. There are multiple possibilities. You can choose between various DHCP clients and network managers.

    Both have the task of providing the network interfaces with an IP configuration. If yes, then disable. After that, a reboot is recommended.

    Before you have to enter the DNS server manually. But that does not fix the basic configuration error. This solution should be chosen only in exceptional cases.

    If the system is not mobile, that would not be a big disadvantage. An effect may be that an interface has two IP addresses or an IP configuration that was not intended. Sometimes you do not notice it. And it does not necessarily have any effect. Nevertheless, one must expect network problems. Analysis This is because one unknowingly runs two different types of IPv4 configuration in parallel. One you forgave yourself and a second, which was somehow allocated via DHCP.

    Both can be pinged and connected via SSH sometimes not. To determine if the problem really exists, we check to see if a DHCP client is installed and running. Note: This solution is not recommended. You then have to live with the advantages and disadvantages. It must be remembered that the syntax differs from each other.

    If you do not want to deactivate the DHCPCD because you need it for an interface, you can also exclude or explicitly release the configuration for an interface. Note: That would be the best of all solutions. In that case, one should prophylactically uninstall all possible DHCP clients. Analysis: Check formatting A missing IP configuration can result from having a format error in one of the configuration files, so they could not be processed correctly.

    Thus, invisible control characters may have been inserted by editing with an inappropriate editor. Solution 2 temporary.

    Raspberry Pi Not Connecting to Wi-Fi

    In a previous tutorialI explained how to establish an SSH connection to your Raspberry Pi over ethernet without using an external keyboard or monitor.

    How to solve “No wireless interface found” on a Raspberry Pi 3

    Connecting with an ethernet cableis great if you want to leave it connected to your router with a physical cable. Be careful when choosing a WiFi adapter for the Raspberry Pi though, because not all of them will work out of the box. I found that this one on Amazon works great without any driver installations needed. Still, there are a couple things that need to be set up for any WiFi adapter to work properly with your Raspberry Pi.

    You should already have set up the SSH connection over ethernet, as described in this post. It covers all of the steps and commands you need to get started.

    This video will walk you through the steps, but see below for more details: Edit the Network Interfaces File With your USB WiFi adapter plugged into the Pi, power up the Pi and connect it to your internet router with an ethernet cable just like we did in the last tutorial. Now press Ctrl-X and Y to exit and save changes to the file. The first thing to do is find out which service spits you into the soup.

    There are multiple possibilities. You can choose between various DHCP clients and network managers. Both have the task of providing the network interfaces with an IP configuration.

    If yes, then disable. After that, a reboot is recommended. Before you have to enter the DNS server manually. But that does not fix the basic configuration error. This solution should be chosen only in exceptional cases.
