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. If you can login to your router configuration page, you shall also find the ip address of the raspberry pi devices under the attached device section.There are a number of common requirements that require configuration. Here you can see a device with hostname raspberrypi has IP address 192.168.1.7. Nmap done: 256 IP addresses (4 hosts up) scanned in 2.41 seconds Nmap scan report for raspberrypi (192.168.1.7) Nmap scan report for ubuntu (192.168.1.5) Nmap scan report for Gordons-MBP (192.168.1.4) Nmap scan report for hpprinter (192.168.1.2) For each device that responds to the ping, the output shows the hostname and IP address like so: Starting Nmap 6.40 ( ) at 12:46 GMT Ping scan just pings all the IP addresses to see if they respond. This may take a few seconds: nmap -sn 192.168.1.0/24 Now use the nmap command with the -sn flag (ping scan) on the whole subnet range. Now you have the IP address of your computer, you will scan the whole subnet for other devices. 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.On Mac OS, go to System Preferences then Network and select your active network connection to view the IP address.On Linux (or Mac OS terminal), type hostname -I into a terminal window.First find your own IP address, in other words the one of the computer you’re using to find your Pi’s IP address: To use nmap to scan the devices on your network, you need to know the subnet you are connected to. To install on Mac OS or Windows, see the download page.To install on Linux Debian or ubuntu or Raspbian, install the nmap package e.g.The nmap command (Network Mapper) is an open-source network discovery tool, available for Linux, Mac OS, and Windows.
