I. Introduction
When the Linux kernel crashes or the server hangs, kdump (kernel crash dump: the kernel crash dump device) generates the vmcore file, and analyzes the vmcore information to determine the cause, crash is a widely used kernel crash dump file analysis tool, which requires the system to install the crash tool and kernel debugging tool kernel-debuginfo.
Ii. Tool installation and debugging
1. The version of the installation package must be consistent with that of the Linux kernel. view

process of active FTP is as follows:1. The customer issues a command to establish a data connection.2. the customer usually selects a temporary port number for the data connection on the client host. The customer publishes a passive open request from the port.3. The customer uses the PORT command to send the port of the data channel to the server from the command channel.4. The server receives the port number on the Command Channel and sends an active open request to the port on the client host

The day before yesterday, a netizen asked about the design mode of the adapter mode (Adapter), said not very good understanding. Can insus.net give a simple example to illustrate. The following animation is the result of insus.net:
The above demo, two lamps of the same specification, requires the input voltage of 15 volts.
LIGHT1 is used directly, while LIGHT2 is using adapter (power adapter). So Light1 can only receive 15 volts of voltage, less than 15 volts, will prompt the voltage is too lo

Four, add a slash after the URL
Some URLs, such as "www.kenengba.com/220", take time to determine the file type of the address when the server receives such an address request. If 220 is a directory, you may want to add a slash after the URL,
to identify network ports on the extended network card.The new naming scheme is opened by default on the supported Dell PowerEdge platform. Passing the ' biosdevname=0 ' kernel command-line argument during installation disables the new naming scheme and retains it at run time.Existing scripts that hard-code the ETHN name may need to be changed to recognize the network device name.

In the Intramfs kernel boot file, we can see the boot script 01parse-kernel.sh in the cmdline/directory. The script is executed before the driver is loaded through the udev mechanism. In this script, you can see parsing kernel parameter rdloaddriver, that is, the kernel first loads the rdloaddriver in the parameter.
The code is as follows
