This is the simple script used for the wireless connection attempts:
ifdown <device_name>
ip link set <device_name> up
pkill wpa_supplicant
wpa_passphrase <essid> <password> > <conf_file>
wpa_supplicant -B -c<conf_file> -i<device_name>
rm -f /run/network/ifstate.<device_name>
ip link set <device_name> up
sleep 1
ifup <device_name>
Maybe, the lines nº 6 and nº7 are superfluous. The line nº8 (that is,
"sleep 1") is important, believe it.
As sysadmins, what do you think about the use of "pkill wpa_supplicant"?
Aitor.
This script needs granted permissions; so, it's included in a suid
binary. Once i talked about a security key for this binary.
The security key would be generated during the compilation of the
application in a way that only those binaries built *together* with the
suid binary will know it.
First of all, i have to deal with the add_custom_command() function of
CMake, in order to control the preference of the targets.
The first step should be to generate this key, before all the executables.
Cheers,
Aitor.
