Pokročilá konfigurace jádra GNU/Linux prostřednictvím NetLink Socket

Abstract

This thesis is focused on explaining how we can use Netlink socket to configure the GNU/Linux kernel's networking subsystem. It is kernel that directly communicates with computer hardware, so when user wants to change something, e.g. an IP address on some interface, s/he will probably use some special utility. These utilities then use a certain method to pass these new configurations to kernel. Netlink socket is one of these methods. My goal in this thesis was to write a program(s) that use Netlink socket and are able to create network tunnels. Founded solution is afterwards documented and tested.
