error: permission denied on key 'dev.parport.parport0.autoprobe'
 

Hi Guys,

When I execute command ' sudo sysctl -a | grep autoprobe'

I get

error: permission denied on key 'net.ipv4.route.flush'
error: permission denied on key 'net.ipv6.route.flush'
error: permission denied on key 'dev.parport.parport0.autoprobe'
error: permission denied on key 'dev.parport.parport0.autoprobe0'
error: permission denied on key 'dev.parport.parport0.autoprobe1'
error: permission denied on key 'dev.parport.parport0.autoprobe2'
error: permission denied on key 'dev.parport.parport0.autoprobe3'

Why is sudo getting permission denied? Do I have to explicitly set permissions somewhere? If yes can you please help where, I am bit new to linux.


I am on Ubuntu 8.04

Thanks,
Amit.
