How things could be solved...

Exercise 6

Assignment 6.1

Assignment 6.2

I'll try pinging specific computers. It used do be possible to ping the broadcast address (i.e. ping -b, however nowadays every computer is configured to ignore broadcast pings.

Assignment 6.3

I add the following lines to /etc/network/interfaces
auto eth0
iface eth0 inet static
and if I really want to, I can also add gateway (this solves me assignment 7.6 for free).

Assignment 6.4

It should be sufficient to use route add -net netmask gw

Priklad 6.5

Ping and be happy panda ;-).

Priklad 6.6

I'll use route add default gw and miraculously I can instantly see the rest of (virtual) world. If I wanted, I could delete the route added in assignment 7.4, given that the new route also covers this old one.
