ipc 4300

These days, for work reasons, a PHP-written background program needs to be re-serialized to parallel execution. This inevitably involves multi-threaded/multi-process related technologies. PHP seems to have no mature multi-threading mechanism, and a relatively mature process mechanism. Multi-process programming inevitably involves the IPC (inter-process communication). The IPC Technology of PHP is still quit

I. Concepts A message queue is a linked list of messages. A process with write permission on a message queue can add new messages to it according to certain rules. A process with read permission on the Message Queue can read messages from the message queue. Message Queues continue with the kernel. The following three concepts are introduced: 1. Continuous with process: IPC always exists until the last process that opens the

I wanted to make a client-server application that wocould run both on WinCE/Windows Mobile 5.0 PPC/SP and windows. Here is what I wanted to make: §ServerEXE which wowould have to run, both on a Win CE based device and on a desktop machine. §ClientEXE which wocould talk to the server. The scenario involved running several instances of client EXE running both on desktop and device. The obvious choice was to write a common server/client code which wocould run both on device and for desktop. So

1. pipelines: pipelines are one of the original Unix IPC formats supported by Linux. They have the following features: pipelines are half-duplex and data can only flow in one direction. Two pipelines need to be established when both parties need to communicate; it can only be used between parent and child processes or brothers (kinship processes). It forms an independent File System: An MPs queue is a file for processes at both ends of the MPs queue,

How to Establish an IPC connection? I don't need to say that everyone knows: Net use // ip // IPC $ password/User: user. Here, we should find a way to get the account and password for administrator permissions. There are many methods: (1) Traffic Scanning (2) null. printer Buffer Overflow (3) ms SQL Empty Password (4) Unicode Vulnerability ⑸ Remote Terminal Input Method Vulnerability ⑹ Idq. dll Vulnerabili

1. Binder (IPC) Linux processes must communicate with each other to share resources and information. Therefore, the operating system kernel must provideInter-process communicationMechanism (IPC, inter-process communication ). IPC Mechanism types: Named Pipe (name pipe), Message Queue (Message Queue), signal (signal), and Memory Sharing (share memory ); The commun

In Android, each application is made up of activity and service that are likely to run in the same process or run in different processes. So how do you communicate with an activity or service that is not in the same process? This is the binder interprocess communication mechanism to be introduced in this article. We know that the Android system is based on the Linux kernel, and the Linux kernel inherits and is compatible with the rich Unix system interprocess communication (

Take advantage of ipc$ intrusion related commands: We will inevitably encounter the time of the invasion to forget the order, now I know some of the commands summed up to provide you. These commands can solve a large part of the Novice's problem. 00:net use Role: Connect the computer or disconnect the computer from the shared resource, or display the connection information for the computer. Command format: NET USE [devicename | *] [\\\\computername\\s

Android uses the binder mechanism to implement IPC, Binder communication is achieved with the help of Linux binder driver, two interprocess IPC feel like a process to enter another process to execute code, and locally can return the result of the remote function. Binder user space maintains an available thread pool for each process, the thread pool is used to process incoming call requests, including the re

I often hear people talk about the IPC vulnerability on the Internet. What is the IPC vulnerability? How do network hooligans exploit this vulnerability? With such a problem, let's take a look at the author's wonderful articles! What is an IPC vulnerability? IPC is a resource that shares Named Pipes and is important fo

The original post of a series of articles about Linux IPC published on the IBM developerworks website is a series of articles by Zheng yanxing, I have demonstrated the use of several IPC methods in Linux Through Explanations and examples. I think it is very good to make a reservation here. If you can finish reading it, the foundation of Linux IPC is no problem.

In interprocess communication mode, each IPC object has a unique name, whether it is using message queue, shared memory, or even semaphores, it is called a key ). Through the "key", the process can identify the objects used. The relationship between the "key" and the IPC object is like the file name in the file. Through the file name, the process can read and write data in the file, and even multiple proces

System V shared memory is similar to POSIX shared memory, and System V shared memory is called the Shmget function and the Shamat function.The Shmget function creates a shared memory area, or accesses an existing memory area, similar to the system calling the open and POSIX shared memory shm_open functions of shared memory. The Shmget function prototype is: #include #include int Shmget (key_t key, size_t size, int shmflg); Key: Function Ftok return value, or ipc_pri

POSIX interprocess communication: includes POSIX Message Queuing, POSIX semaphore, POSIX shared memory. In Linux, IPC-related commands include: IPCS, IPCRM (release IPC), The IPCS command is a tool for displaying the state

First, let's get to know what ipc$ is. ipc$ (Internet Process Connection) is a resource that shares a named pipe, which is a named pipe that is open for interprocess communication, by providing a trusted username and password, where both parties can establish secure channels and exchange encrypted data with this channel. This enables access to the remote computer. Ipc
