Gyakorlat =
- A fenti ábrának megfelelően a hálózat tartalmazzon egy munkállomást és egy szervert!
- A router DHCP-n adjon hálózati paramétereket a munkaállomásnak!
- A szerver IP címe legyen 192.168.0.10, ezt a router nem oszthatja ki munkaállomás számára!
- Készítsünk webszervert, amely a nevünket jeleníti meg!
- Készítsünk DNS szervert, amely a www.facebook.com névvel jeleníti meg ezt a weboldalt!
- Készítsünk alternatív DHCP szervert!
