If you need to increase the parameter worker_connections When configuring nginx, you need to set the file descriptor of the system, otherwise, the following error may occur: worker_connections exceed open file resource limit: 1024(1) Modify/etc/security/limits. in the conf file, add the following lines to the file: * soft noproc 65535 * hard noproc 65535 * soft nofile

System callsThe process has two modes of operation: User state and kernel state. The process is usually in the user state, when the CPU and memory can be used, and when the process needs to operate on the hardware peripherals (such as reading disk files, sending network data), it must switch to the kernel state, when the kernel-state task is completed, the process is then cut back to the user state.Because the system call involves the process from the user state to the kernel state of the switch

Using NMAP to scan and identify servicesNmap is probably the most widely used port scanner in the world. He can be used to identify active hosts, scan TCP and UDP open ports, detect firewalls, get service versions running on remote hosts, or even use scripts to discover and exploit vulnerabilities.In this cheats, we use Nmap to identify all the services running on the target application. For instructional purposes, we will invoke Nmap several times to implement it, but this can be done with a s
