Linux servers start with a number of system services that provide local and network users with a system-functional interface for Linux that is directly targeted to applications and users. The programs that provide these services are executed by daemons running in the background (daemons). A daemon is a process that has a long lifetime. They are independent of the control terminal and periodically perform certain tasks or wait to handle certain occurrences. They often start when the system

　Method One:GRUB: On the boot loader menu, type [e] to enter edit mode. You will face a list of boot projects. Look for a line that resembles the following output: kernel/vmlinuz-2.4.18-0.4 ro root=/dev/hda2 Press the arrow key until the line is highlighted, and then press [E]. You can now empty a box at the end of the text and add a single to tell the GRUB boot-user Linux mode. Press the [Enter] key to make the edit result effective. You will be brought to the edit mode screen, from here, press

Intro-----The daemon, which is usually called the daemon process, is the background service process in Linux. It is a long-lived process, usually independent of the control terminal and periodically performs some sort of task or waits to handle certain occurrences. Daemons often start when the system boots, and terminate when the system shuts down. Linux systems have many daemons, most of which are implemented through daemons, while the daemon can acc

, while the PXE client is in the ROM of the NIC. When the computer boots, the BIOS directs the PXE client into memory and then the files that are placed at the remote end by the PXE client are downloaded locally to run on the network. Running the PXE protocol requires setting up a DHCP server and a TFTP server. The DHCP server assigns an IP address to the PXE client (the host that will install the system), and because it assigns an IP address to the P

memory.Another simple mention of two data structures:Each file system type that is registered to the kernel is represented by a struct FILE_SYSTEM_TYPE structure, and each file system type has a linked list that points to all the super blocks belonging to the file system of that type.When a file system is mounted on a directory tree of the kernel file system, a mount point is generated to manage the information of the mounted file system. The mount point is represented by a struct VFSMOUNT stru

own network settings and ARP are not a problem. The routing table can be displayed by the command "Route-n", and then the address of the gateway is obtained. If the default gateway is not set in the routing table, there is a problem with the routing settings and you need to set the default gateway.Sometimes, there are ARP attacks in the LAN or other reasons, so that the MAC address of the gateway IP in the native ARP cache is wrong, which can also cause the gateway to ping. At this point, you c

network port type driver also has a specialized interface:Register_netdev (Ndev);After registering the network port is managed by the kernel.Second, there is no special driver registration functionThis type of driver registration is straightforward and follows the generic character-driven function. such as the watchdog class driver.
