# STRATUX QUIET HOSTAPD MANAGE #
|
|
######################################################################
|
|
# This script is almost identical to hostapd_manager.sh except all the
|
|
# screen outputs are supplressed except for error messages.
|
|
#
|
|
# Usage:
|
|
# hostapd_manager_quiet.sh -s Stratux-N12345 -p SquawkDirty! -c 5
|
|
# Command above sets the SSID to "Stratux-N12345, secures the network with the passphrase "SquawkDirty!, and changes the network channel to "5"
|
|
#
|
|
# hostapd_manager_quiet.sh -o
|
|
# Command above opens the network(removes any passphrase)
|
|
#
|
|
# hostapd_manager_quiet.sh -e
|
|
# Command above secures the WiFi network using the default passphrase "SquawkDirtyToMe!"
|
|
|
|
# Options:
|
|
# -s --Sets the SSID to ${BOLD}ssid${NORM}. -s stratux
|
|
# -c --Sets the channel to chan. -c 1
|
|
# -o --Turns off encryption and sets network to open. Cannot be used with -e or -p.
|
|
# -e --Turns on encryption with passphrase SquawkDirtyToMe!. Cannot be used with -o or -p
|
|
# -p --Turns on encryption with your chosen passphrase pass. 8-63 Printable Characters(ascii 32-126). Cannot be used with -o or -e. -p password!
|
|
#
|
|
# Important:
|
|
# After each call of this script the wifi network will disconnect and restart all associated services to apply the changes
|
|
|
|
#Set Script Name variable
|
