Fedora 19 USB automount doesn't work : SOLVED

Having installed Fedora 19 Schrodinger's Cat recently, a problem came up that the USB that used to get auto detected in earlier versions stopped working......and could not be seen anywhere in the file manager...and the disk showed the following screen which has no USB disk.

(CLICK ON THE IMAGE TO ENLARGE)

But the good thing is that on doing LSUSB at the terminal it was being shown as follows :

Bus 001 Device 002: ID 4033:0042 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 4051:0030 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 3d4b:0008 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1f6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0f6d:081b Logitech, Inc. Webcam C310
Bus 001 Device 004: ID 0c61:4d0f Primax Electronics, Ltd HP Optical Mouse
Bus 002 Device 005: ID 03f0:5201 Sandisk 

so mounted it the terminal way..

make a directory in home by the name of usb

mkdir usb

and

at the terminal type lsblk that will give you where to mount.In my case it is sdc1. My output comes as follows :

NAME            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda               8:0    0 931.5G  0 disk 
├─sda1            8:1    0 488.3G  0 part 
└─sda2            8:2    0 443.2G  0 part

└─sdc1            8:33   1    30G  0 part /home/kalama/usb
sr0              11:0    1  1024M  0 rom 

now at the terminal simply type

mount -t vfat /dev/sdc1 /home/kalama/usb/


thats it ..now it will start showing when you do df -h as shown below :

[root@localhost ~]# df -h

Spying your friend at WhatsApp : Cause of concern

1.   In my last post here,I discussed about the growing lure of using WhatsApp and the basic security concerns that comes with it from point of a naive user.Now will take you one step higher to the level of a script kiddie....

2.  How does WhatApp identify you in billions?The answer is the unique MAC address that each digital device on this earth holds. If any one changes his/her device,then automatically the MAC address also changes and the user is requested to re-verify their WhatsApp account. Means he/she cannot access same WhatsApp account from two devices. But is MACSPOOFING not existing ?So,if the Mac is spoofed,then who stops from seeing your friends traffic that includes his/her chats,downloads etc!!!although for a naive user this may be look of some technical nature but for the young gen which has lots of techno enthusiasts there should be no stopping....that would include rooting your phone and installing Busybox. How to get your friends MAC address,here it goes :

For Android phone users simply go to settings—> About phone—> Status—> Wi-Fi MAC address.

For iPhone users go to Settings—> General—> About—> Wi-Fi address.

For Windows Phone users go to Settings—> About—> More info—> MAC address.

and for BlackBerry users go to options—> Device—> Device and Status info—> WLAN MAC.

3.   And the best part is that your Andorid can be anyone starting from 1.6 on wards till date.
