Kubuntu is an entirely open source operating system built around the Linux kernel. The Kubuntu community is built around the ideals enshrined in the Ubuntu Philosophy: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit.

Network Configuration in Kubuntu
Most ethernet configuration is centralized in a single file, /etc/network/interfaces. If you have no ethernet devices, only the loopback interface will appear in this file, and it will look something like this:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
iface lo inet loopback
If you have only one ethernet device, eth0, and it gets its configuration from a DHCP server, and it should come up automatically at boot, only two additional lines are required:
iface eth0 inet dhcp
The first line specifies that the eth0 device should come up automatically when you boot. The second line means that interface (“iface”) eth0 should have an IPv4 address space (replace “inet” with “inet6” for an IPv6 device) and that it should get its configuration automatically from DHCP. Assuming your network and DHCP server are properly configured, this machine's network should need no further configuration to operate properly. The DHCP server will provide the default gateway (implemented via the route command), the device's IP address (implemented via the ifconfig command), and and DNS servers used on the network (implemented in the /etc/resolv.conf file.)
To configure your ethernet device with a static IP address and custom configuration, some more information will be required. Suppose you want to assign the IP address 192.168.0.2 to the device eth1, with the typical netmask of 255.255.255.0. Your default gateway's IP address is 192.168.0.1. You would enter something like this into /etc/network/interfaces:
iface eth1 inet static
In this case, you will need to specify your DNS servers manually in /etc/resolv.conf, which should look something like this:
The search directive will append mydomain.com to hostname queries in an attempt to resolve names to your network. For example, if your network's domain is mydomain.com and you try to ping the host “mybox”, the DNS query will be modified to “mybox.mydomain.com” for resolution. The nameserver directives specifiy DNS servers to be used to resolve hostnames to IP addresses. If you use your own nameserver, enter it here. Otherwise, ask your Internet Service Provider for the primary and secondary DNS servers to use, and enter them into /etc/resolv.conf as shown above.
