NAME

networking, wifi – quickstart guide to connecting to a network

CONTENTS

DESCRIPTION

In the following examples, it is assumed that we are connecting to Ethernet with the first interface found by the ix(4) driver, and Wi-Fi with the first interface found by the iwlwifi(4) driver, though your hardware will vary.

EXAMPLES

Example 1: Connecting to an Ethernet network with DHCP
 

Ask for a DHCP lease on the first Intel 10Gb Ethernet interface: 

 # dhclient ix0
Example 2: Connecting to a cellular network with USB tethering
 

Ask for a DHCP lease on the first USB tethering interface: 

 # dhclient ue0
Example 3: Connecting to a Wi-Fi network
 

Identify your Wi-Fi hardware: 

 % sysctl net.wlan.devices

Create the wlan0 interface with the first Intel Wi-Fi adapter: 

 # sysrc wlans_iwlwifi0="wlan0"

Set that interface to ask for a DHCP lease with wpa_supplicant(8): 

 # sysrc ifconfig_wlan0="WPA SYNCDHCP"

Enter the details of the Wi-Fi network: 

 # cd /etc/
 # wpa_passphrase dqmyssiddq dqmypassphrasedq >> wpa_supplicant.conf

Restart the network interface daemon: 

 # service netif restart
Example 4: Scanning for Wi-Fi networks
  
 % ifconfig wlan0 scan
Example 5: Airplane mode
  
 # service netif stop

CAVEATS

Shell Special Characters in the SSID or passphrase will need to be escaped for wpa_passphrase(8), commonly using ‘\’, see the manual page for your shell for more details.

Stopping the network interface service also stops internal networking.

“ "I liken starting one's computing career with Unix, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases. But, as far as young East Africans can tell, this is simply the natural condition and they live within it. By the time they find out differently, it is too late. They already think that the writing of shell scripts is a natural act." ”
