+  Aufgabe: Vernetzen Sie Ihre Rechner mittels TCP/IP.
+  \begin{itemize}
+    \item
+      Stellen Sie eine geeignete Hardware-Infrastruktur her.\\
+      (Kabelgebundenes Netz, WLAN, Avian Carriers, \dots)
+    \item
+      Wählen Sie geeignete IP-Adressen und prüfen Sie mittels \lstinline[style=cmd]{ping}
+      die gegenseitige Erreichbarkeit.
+    \item
+      Stellen Sie mittels Netcat (\lstinline[style=cmd]{nc})
+      TCP-Verbindungen her (Ende-zu-Ende-Chat).
+    \item
+      Bieten Sie (z.\,B.\ mittels \lstinline[style=cmd]{nc -e})
+      in diesem Netz Dienste an und testen Sie diese.
+    \item
+      Untersuchen Sie den Netzwerkverkehr mittels tcpdump und/oder Wireshark.
+    \item
+      Testen Sie, wie sich externe Dienste (Webseiten, E-Mail)
+      mittels \lstinline[style=cmd]{nc} nutzen lassen.
+  \end{itemize}
