Recently, the company has made the following changes to security settings:

The/dev/null file is changed to a common file with the permission of 000. As a result, glance cannot be used.

After HP Beijing 800 diagnosis, the file was indeed changed. The steps to change back are as follows:

1. RM/dev/null

2. mknod/dev/null C 3 0x000002

3. chown bin: Bin/dev/null

4. chmod 600/dev/null
