Your redirection is not run as root, only cat
does.
Try the following:
sudo sh
# cat > /dev/rb
Once it works, combine into a single command line (most probably: sudo "cat > /dev/rb"
)
سؤال
I am trying to write a block device driver that reads/writes off of the network. In essence, I have modified the example here for ram disks. And Here is my code. When I try to write to the block device using the command sudo cat > /dev/rb
, I get premission denied.
$ sudo cat > /dev/rb
bash: /dev/rb: Permission denied
Can Anyone help me fix this??
I can see nothing suspicious in the kernel log.
Thanks in advance!
