Now, we must convince Congress to stop the FCC. Can you display an alert?

To find all the saved WIFI passwords and Ethernet connection information on your Linux desktop or laptop, navigate to this directory.

/etc/NetworkManager/system-connections

Here are the connections on my laptop.

┌─[root@parrot][/etc/NetworkManager/system-connections]
└──╼ #ls -hula
total 20K
drwxr-xr-x 2 root root 4.0K Aug 24 13:36 .
drwxr-xr-x 7 root root 4.0K Aug 24 13:29 ..
-rw------- 1 root root  369 Aug 24 13:33 NetComm Wireless
-rw-r--r-- 1 root root  191 Aug 24 13:30 NetworkManager-USRP
-rw------- 1 root root  375 Aug 24 13:19 OPTUSVD3AEDEA

This is what a WIFI connection file looks like. This stores the Pre Shared Key in plain text.

┌─[root@parrot][/etc/NetworkManager/system-connections]
└──╼ #cat NetComm\ Wireless 
[connection]
id=NetComm Wireless
uuid=2a64036c-fa4f-48db-9f7e-c93fc9eb066a
type=wifi
permissions=user:jason:;
 
[wifi]
mac-address=F4:B7:E2:C9:1B:E3
mac-address-blacklist=
mode=infrastructure
ssid=NetComm Wireless
 
[wifi-security]
auth-alg=open
key-mgmt=wpa-psk
psk=a1b2c3d4e5
 
[ipv4]
dns-search=
method=auto
 
[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

So this is how to recover a WIFI password if you have forgotten it. A very useful Linux tip. Recovering passwords in Android is similar. The passwords on an Android phone are stored in the wpa_supplicant.conf file in the /data/misc/wifi directory, but this is not accessible unless you are using a rooted phone. Linux is easy though, the files are not accessible unless you are using a root prompt or sudo.

┌─[jason@parrot][~]
└──╼ $cat /etc/NetworkManager/system-connections/NetComm\ Wireless 
cat: '/etc/NetworkManager/system-connections/NetComm Wireless': Permission denied

So, this is relatively secure. This is what the Ethernet connection configuration looks like.

┌─[][root@parrot][/home/jason]
└──╼ #cat /etc/NetworkManager/system-connections/NetworkManager-USRP 
[802-3-ethernet]
duplex=full
 
[connection]
id=USRP
uuid=f6a7696d-4958-48f4-b1eb-c2ab9de0a838
type=802-3-ethernet
 
[ipv6]
method=auto
 
[ipv4]
method=manual
addresses1=192.168.10.1;24;0.0.0.0;

Here is how to get the passwords on Windows 7 or 8.1.
