Hi There are instances in which my machine is connected to a mobile hotspot. And in some situations, it's connected to a smartphone via USB tethering. And when I'm in the office, I may connect it to a LAN cable.
Below are the contents of my /etc/network/interfaces file: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug enx61s07 #iface enx60a4b79d7f48 inet static # address 192.168.1.35/24 # gateway 192.168.1.1 # dns-* options are implemented by the resolvconf package, if installed # dns-nameservers 1.1.1.1 8.8.8.8 # The primary network interface for USB tethering allow-hotplug usb0 iface usb0 inet dhcp static address 192.168.42.35 gateway 192.168.42.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 1.1.1.1 8.8.8.8 # The primary network interface for wireless connections #allow-hotplug wlo1 #iface wlo1 inet dhcp static # wpa-ssid Osia27 # wpa-psk string-of-alphanumberice-characters # address 192.168.43.28 # gateway 192.168.43.1 # dns-nameservers 1.1.1.1 8.8.8.8 Questions: 1. At the moment, if I wish to change to using a mobile hotspot from USB tethering, I'll edit the /etc/network/interfaces file, uncomment the applicable lines under #The primary network interface for wireless connections and place a # in front of all the lines under #The primary network interface for USB tethering Instead of carrying out the above steps, is there a neater and simpler way? 2. What is the command to type in a terminal after I have made changes to the /etc/network/interfaces file without rebooting my machine? Best regards. Stella
