# Networking

 1. Today, we will learn a bit about networking.
 2. In the first half, we will look at networking from the user
    perspective.
 3. That includes a few diagnostic tools (‹ping›, ‹traceroute›),
    general-purpose utilities (‹nc› a.k.a. netcat and ‹telnet›).
 4. But also clients for well-established protocols, like HTTP
    (‹curl› and ‹wget›), SSH and DNS (‹dig›).
 5. In the second half, we will look at network (‹AF_INET›) sockets.

Let's start with ‹ping› and ‹traceroute›: ‹cat ping.sh›.
