Kali linux wpa_supplicant cli config

Kali linux wpa_supplicant cli config. To setup a wifi connection using wpa_supplicant on the cli in kali, first you have to bring up your network interface

ifconfig wlan0 up

Next, we create a config file

wpa_passphrase 'router_ssid' 'wifi_password' > /etc/wpa_supplicant.conf

We need to edit the config file and remove some things

vim /etc/wpa_supplicant.conf

Change the config file so that it contains:

network={
    ssid="router_ssid"
    #psk="wifi_password"
    psk=long_hex_string_goes_here
}

Finally, we can auth with our router and obtain an ip address to access the network

sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext
sudo dhclient wlan0

Command Line Options (taken from the wpa_supplicant man page) Most command line options have global scope. Some are given per interface, and are only valid if at least one -i option is specified, otherwise they are ignored. Option groups for different interfaces must be separated by -N option.

-b br_ifname Optional bridge interface name. (Per interface) -B Run daemon in the background. -c filename Path to configuration file. (Per interface) -C ctrl_interface Path to ctrl_interface socket (Per interface. Only used if -c is not). -i ifname Interface to listen on. Multiple instances of this option can be present, one per interface, separated by -N option (see below). -d Increase debugging verbosity (-dd even more). -D driver Driver to use (can be multiple drivers: nl80211,wext). (Per interface, see the available options below.) -f output file Log output to specified file instead of stdout. -g global ctrl_interface Path to global ctrl_interface socket. If specified, interface definitions may be omitted. -K Include keys (passwords, etc.) in debug output. -t Include timestamp in debug messages. -h Help. Show a usage message. -L Show license (GPL and BSD). -p Driver parameters. (Per interface) -P PID_file Path to PID file. -q Decrease debugging verbosity (-qq even less). -u Enabled DBus control interface. If enabled, interface definitions may be omitted. -v Show version. -W Wait for a control interface monitor before starting. -N Start describing new interface.
