Written:Modprob drv------Modprobe is used to load the kernel module like insmod.However, modprobe is intelligent and can be automatically loaded for you based on module dependencies;Insmod cannot do this.

Cobbler remotely installs CentOS and cobbler installs centosThis article explains how to remotely install CentOS through IPMI and PXE.1. First, use Cobbler to add a system

the Cobbler configuration, a configuration file specifies Domain=mydomain.com, and each machine that uses the configuration file specifies its name in the machine_name variable. All machines in the configuration file are installed with the same kickstart and configured for domain=mydomain.com, but each machine has its own machine name. You can still use the Kickstart template to install other machines in different domains and use different machine names.To assist with the management system, the
The previous period took part in a tournament, which was broadly applied and extended OpenStack, as shown in the requirements:Ironic manages and controls the physical machine by periodically executing the Ipmitool command on the physical machine to obtain the SEL (System event log) information for the physical machine, ironic sends the collected SEL information to the Ceilometer via the AMQP protocol, Ceilometer persists the collected SEL information

There are two loading methods for Linux Device Drivers: insmod and modprobe. The following describes their usage differences.
1. insmod can only load a specific device driver at a time, and the specific address of the driver is required. Written:
Insmod DRV. Ko
2. modprobe can load all dependent drivers to the kernel at a time. Without the specific driver address, you must install the driver module in the make modues_install method when installing the file system. The driver is installed unde

Refer to the lldp protocol standards. As long as this protocol is enabled on the switch end, I can capture and locate my switch model and port on the client. However, this is not suitable for Automatic Topology statistics.
Check the Cabinet location:
The location of the Cabinet is unknown on the server side, but the general location of the cabinet can be verified through the switch. Because the switch is located on a previously known port, then mac
