The first step in setting up our network is to determine the name of
the network device that we are going to connect with. We're goind to
start by running the
ip command to list our interfaces, and then once
that is done we can move on to setting up our connection in one of the
following subsections for wired or wireless as appropriate.
ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether dc:a6:32:2a:97:94 brd ff:ff:ff:ff:ff:ff 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DORMANT group default qlen 1000 link/ether ca:d0:a4:6c:cf:5d brd ff:ff:ff:ff:ff:ff permaddr dc:a6:32:2a:97:95
The results for
1: lo ... represent the loopback interface. We also
see an ethernet device
eth0 and a wireless device
wlan0. To configure
the ethernet interface
eth0 go ahead to the section
wired. If instead you intend to use the wireless interface
wlan0 proceeed to section wireless.
