If I am correct, ESS is the union of a set of BSS's. ESSID and BSSID are just their IDs respectively.
How can I tell if a wireless network has essid, bssid or ssid? What differences are between usages of essid, bssid and ssid? When to use which?
Which one should apply to the wireless network created by my router in my apartment: ESSID, BSSID, or SSID?
Some examples of commands that use ESSID, BSSID or SSID as their arguments. But I am not sure why they use one not the others.
The manpage of
iwconfig
saysNAME iwconfig - configure a wireless network interface SYNOPSIS iwconfig [interface] iwconfig interface [essid X] [nwid N] [mode M] [freq F] [channel C][sens S ][ap A ][nick NN ] [rate R] [rts RT] [frag FT] [txpower T] [enc E] [key K] [power P] [retry R] [modu M] [commit] iwconfig --help iwconfig --version
Why does it have an argument
essid
rather thanbssid
? Does a wireless network interface always work with a ESS not a BSS?wpa_cli
has a commandbssid <network id> <BSSID> set preferred BSSID for an SSID
Why does it use BSSID instead of ESSID as
iwconfig
does?wpa_passphrase
uses an argument for a SSID, does it mean the argument can be either BSSID or ESSID?SYNOPSIS wpa_passphrase [ ssid ] [ passphrase ]
wicd-wired-settings.conf
has the following settings:bssid = <BSSID_of_network> This value can be found using iwconfig(8). essid = <ESSID_of_network> This value can be found using iwconfig(8).
Can
iwconfig
tell if a network is ESS or BSS?
Thanks!
