HI,<br>
<br>
This is my first mail to this mailing list.I want to block external
usb storage completly on my server running on centos 5 having
confidiential data.<br>
<br>
For that i used udev and blocked the external usb storage by creating
the udev rule mentioning any usb storage will get mounted to /dev/null
so that users cant mount as well.<br>
<br>
But in the mean time i am getting below logs in my /var/log/messages file when i insert any usb storage device.<br>
