Hi
i teach computer science in a high school and i want to use some pc
supporting ubuntu or other linux version;
from a security point of view i want
to prevent students from using usb flash devices to copy files from pc or
to
copy files in the pc.
I wrote this kind of rule for udev (i named it 10-
chiavetta-usb.rules)
ACTION=="add", KERNEL=="sd[b-z][0-9]*", SUBSYSTEM=="usb",
ATTRS{removable}=="True", ATTRS{product}=="?*", NAME="chiavettausb%k",
GROUP="
root" OWNER="root"
but it has a strange behavior: when an unprivileged user
(as ubuntu define it) insert a usb flash device the system mount it and
create
the directory with the owner the current user (not root as specified by the
udev rule) and when inserting a second usb flash device the system create
the
directory but with root as owner denying the access to the user: i want
that
each inserted usb flash device cannot be mounted by the unprivileged user.
What is wrong with my udev rule? I am new with linux and system
administration.
Thanks a lot, andrea
