Introduction
wifi-select is a console tool for selecting wireless networks in "real-time" (in NetworkManager fashion). The tool might be convenient to use in Internet cafés or other places you are visiting for the first (and maybe the last) time. With wifi-select you do not need to create a profile for a new network, just type:
$ sudo wifi-select wlan0
and choose the network you need. In order not to type "wlan0" every time, you can set it (or make sure it is already there) in $WIRELESS_INTERFACE in /etc/conf.d/netcfg
wifi-select is currently packaged and available in the community ArchLinux repository. To install it, please run:
# pacman -S wifi-select
Synopsis
Usage: wifi-select [-p | --show-pass] [-x | --pass-in-hex] [--use-dhclient] [-h | --help] [interface]
Shows a list of available wireless networks and interactively connects to
the network you select, asking for a password if needed.
Arguments:
-p, --show-pass show password characters instead of '*' while typing a password,
(by default it shows '*')
-x, --pass-in-hex store the entered WPA password as a hexadecimal string
(using wpa_passphrase)
--use-dhclient use "dhclient" instead of "dhcpcd" in generated profiles
-h, --help show this help
interface a wireless interface to use
(if omitted, uses WIRELESS_INTERFACE from /etc/conf.d/netcfg)
Functionality
wifi-select does the following and nothing more:
-
parses
iwlist scanresults and presents a list of networks along with their security settings (WPA/WEP/None) and signal quality using "dialog" tool -
if a user selects a network with an existing profile -- it uses this profile to connect with "netcfg"
-
if the user selects a new network (which doesn't have a profile yet), wifi-select automatically generates a new profile with corresponding $SECURITY and asks for the key (if needed). The key for WPA may be stored as a hex string generated by
wpa_passphrase. wifi-select uses DHCP as $IP by default -
if a network connection succeeds, the profile is saved for later usage
-
if a network connection fails, the user is asked whether he/she wants to keep the generated profile for further usage (for example to change $IP to static or adjust some additional options)
