Fix for “Cannot open master raw device ‘/dev/rawctl’ (No such device or address) “

Tags: ,

For some reason the device /dev/rawctl has a habit of disappearing. This can be fixed by creating the device file /dev/rawctl with the major/minor number 162,0

mknod /dev/rawctl c 162 0
 

This will allow /dev/raw devices to be created. However /dev/raw/raw0 cannot be used since 162,0 is used by /dev/rawctl.

    Hey, thanks for the tip! It’s been a long time since I had to use mknod.
