Install Net-tools by running the following commands: make && make update If you want to accept all the default answers, you can run these commands instead: yes "" | make && make update If you don't know what to answer to all the questions asked during the make phase, then just accept the defaults, which will be just in fine in the majority of the cases. What you are asked here are a bunch of questions relating to the kind of network protocols that you have enabled in your kernel. The default answers will enable the tools from this package to work with the most common protocols such as TCP, PPP and a bunch of others. You still need to actually enable these protocols in the kernel. What you do here is merely telling the programs to be able to use those protocols but it's up to the kernel to make it available to the system.
