I haven’t tried this What is the Name of the GUI Used for Configuring Networking? However you can switch back to using the interfaces file by disabling the dhcpcd and enabling the networking daemon sudo systemctl disable dhcpcd It’s a good idea to change it back but it doesn’t seem to have any effect. I’ve edit the /etc/network/interface File What should I do? The go to a command prompt and change to the /etc folder and type : If for example you have an IP address of 192.168.1.41 and don’t know where this is coming from. You use the ifconfig command to bring the network Interface down and then up and the change will take affect use: sudo ifconfig wlan0 down #wi-fi When you make a change to the IP address or any of the network settings they are not automatically applied you can apply then using the ipconfig config. See this thread – dhclient vs dhcpcd Implementing IP Address Changes ![]() This is the file that the GUI changes Dhclient and dhcpcd DaemonsĪgain most tutorials on the Internet have you changing the /etc/dhcp/nf file and also show commands lineĭoing this on PI has no effect as it uses dhcpcd daemon and not the dhclient daemon. The file you need to edit for Jessie,Stretch and Buster is the /etc/nf file. It seems that most of the tutorials you find on the Internet are not longer valid as they were written for Debian Wheezy and all use the /etc/network/interfaces file. In the screen shot below you can see that on my upgrade Pi (Stretch to Buster) both the dhcpcd and the wicd daemons are running. To find out what daemons you have running use the command: service -status-all Over the years they have moved from the original daemon which used the /etc/networking/interface file to the now more common dhcpd.īut there are other like the wicd which is apparently a wrapper over dhcpd and I found running on my PI that I had upgraded from Stretch to Buster. It seems that there are many different networking daemons that you can use on Linux and PI. Well all my searching wasn’t in vain, as I stumbled across this article by Scargill which related his tribulations with configuring networking and included a very useful bit of history. What a Happened to the /etc/networking/interface file You may also find that it the /etc/nf is empty if you haven’t made any network changes. You will also notice the IPv6 addresses which I disabled! I’ll work that out another day. You will notice the Wi-fi has the correct address the Ethernet port doesn’t has I haven’t got a cable plugged into the port but the card is present as you see a MAC address. If I do an ifconfig then this is what I see. If I look at my /etc/nf file and right at the bottom I see these entries which correspond to my GUI entries. Well after spending hours searching online I’d finally found the answer. If you look for the static IP address you’ve just configured in the GUI and which works then it is nowhere to be found. If you go to these files they are either mainly empty or mainly commented out. So the settings you change in the GUI are stored in one of those files is the logical conclusion that I came to. If you do some Goggling on configuring static IP addresses etc then you will come across many tutorials that take you through either editing the /etc/networking/interface file or /etc/dhcp/nf file. I have also disabled ipv6 on these interfaces. I’ve also enable the checkbox Automatically configure empty options and because of this the default Gateway (router) and the DNS server addresses will come from the DHCP server. In the screen shot below I have configured the Wireless Interface to use a static IP address of 192.168.1.42 and the Ethernet Interface to have an IP address of 192.168.1.41 To make changes you first need to select the Interface using the drop down box. However for most of us using a GUI is easier and PI provide one in the top right task bar. They are:īeing Linux then there are several commands and configuration files that need to be used/edited. There are a number of common requirements that require configuration. ![]()
