SETTINGS FOR THE MOUSE ON REDHAT LINUX 7.2
When connecting the server switch unit to the server on which RedHat Linux 7.2 is installed via the
dedicated cable K410-118, RedHat Linux 7.2 may fail to detect the mouse device.
In such a case, change the settings of RedHat Linux 7.2 as described below.
1. Check if the symbolic link for the device has been created on the shell prompt.
(Enter the underlined character strings.)
[root@localhost]# ls -l /dev/mouse <Enter>
If the message "No such file or directory" is displayed, create the symbolic link as shown
below.
2. Create the symbolic link for mouse device.
[root@localhost]# cd /dev <Enter>
[root@localhost]# ln -s input/mice mouse <Enter>
Tips
You need to log in the system as the user with administrator authority (root) to
create the symbolic link.
