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.
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.
But in the mean time i am getting below logs in my /var/log/messages file when i insert any usb storage device.
