Configure the Samba service for the RHCE simulated test and share the/home/movie file directory. Only 192.168.0.0/24, 192.168.1.0/24, and 127.0.0.1 can be accessed. The shared file name is [Movie File]. the user cannot view it. Only the student group has the write permission. At the same time, you must share the home directories of every user in the student group, and set Netbiosname = GUEST200X # rpm-iv Configure the Samba service for the

The multi-path DM-Multipath of the device mapper in a Linux cluster allows you to configure multiple I/O paths between the server node and the storage array as a single device. These I/O paths are physical SAN connections that can contain independent cables, switches, and controllers. Multi-path sets the I/O paths and generates new devices composed of these integrated paths. This video shows the tutorial of the Linux cluster in the old studio and explains the DM-Multipath and Its configuration.
