Hard interrupts:1. Synchronous interrupt (internal interrupt/exception)The interrupt that is triggered within the core when the interrupt occurs. Wait for the pipeline to complete before you can perform the interrupt. Contains soft interrupt instructions. The broken flag is set by the software or hardware.2. Asynchronous interrupt (external interrupt/interrupt)The interrupt that is triggered by the core outside when the interrupt occurs. Does not wait

)Enable the virtual user. The default value is No.Guest_username=ftpThis is used to map virtual users. The default value is FTP.Virtual_use_local_privs=yes/no (NO)When this parameter is activated (YES), the virtual user uses the same permissions as the local user. When this parameter is closed (NO), the virtual user uses the same permissions as the anonymous user. By default, this parameter is off (NO).16. Other Settingstext_userdb_names= yes/no (NO)Sets whether a UID, GID, or a specific user na

Jmpi is an inter-segment jump instruction for x86 real mode,such as: Bootseg = 0x0c70Jmpi 4, #BOOTSEGIf the current segment cs==00h, then the execution of this instruction will jump to the segment Cs==0x0c70, of course, the value of CS is also changed to 0x0c70, followed by the instructions 0x0c70:0004 instructions.Real-mode addressing is to be compatible with 8086 processors, 8086 is 16-bit CPU (the data width of the Alu), and 20-bit address bus addr

The Apachectl command in Linux is designed to help administrators control the functionality of the Apache httpd daemon. The Apachectl script has two modes of operation. First, as a simple httpd front-end program, set all the necessary environment variables, then start the httpd, and pass all command-line arguments. Second, as a SYSV initialization script, accept simple arguments for one word, such as start, restart, stop, and send them as appropriate signals to httpd. Below and small weave toget
