Enter the following code in the shell to establish br0 and eth0:Brctl ADDBR br0brctl addif br0 eth0ifconfig br0 192.168.0.10 netmask 255.255.255.0 upThen execute the tap.c file we wrote in another shell terminal, with the following code:GCC tap.c-o taosudo./tap tap100program execution, and then write the code in the first shell:sudo ip link

Here the IP is the server's public network IP.This allows the device side to execute shell commands on the server side.Asynchronously initiating a reverse shellIn Project practice we used MQTT, and the client and the server

peripherals, not all peripherals use I/O ports to access peripherals, such as most PCI devices map their registers to a memory address segment, allowing access to these peripherals directly through memory. In contrast, the use of memory to access peripherals is better, because it does not require the use of special instructions, CPU access to memory is more efficient. 1.2 access to hardwareWhen accessing a hardware register, you must avoid unexpect

working with the use of Tap/tun devices to achieve virtual networks, see the online examples are implemented in C. The main thing to try to do with Python is to reuse the ctypes definition of the relevant structure. code GitHub Address: Https://github.com/happyAnger6/network_programming This git library will continue to use Python to implement network-related programming. if_tun.py: Is mainly related to the definition of structural body.

Therefore the measuring script must be efficient. How does compiled the code compare with interpreted code in terms of speed? The ARM platform may be like this: # cat/sys/devices/virtual/thermal/thermal_zone

Doing these things before is done through Virt-manager. However, because this graphical interface is not very convenient, and can not open now (the specific reason is not known, each turn prompts some methods do not realize what), so try to use Libvirt command Virsh to handle the increase of USB devices. This time to add shuffle, previously found that gtkpod can not put music to the inside, only to try the virtual machine with itunes. The first lo

Secondly, when the designer realizes, it needs to do input mode analysis for each input field, then adjust, call or design the corresponding input means to reduce the user's interactive cost and improve the usability. When you log into Gmail and enter the account domain, the iphone offers @ but when you log on to Sina Weibo (3g), it's not, is Sina Weibo supposed to solve it? Third, devices, operating systems and browsers, the underlying module

Mobile control of Asp+ If media news and advertising are to be believed, we will be using small phones or other mobile devices to access the Internet in the near future. OK, this one is a more optimistic estimate, but one thing is certain that visitors to your site already have a lot of people who are not using traditional browsers , and the number is still increasing (SINA news: According to statistics, the global mobile phone users have exceeded com

This document describes the dynamic DNS VPN in IPSec VPN, where two fortigate devices establish a communication channel between them, allowing the servers or hosts that the FortiGate protects to access each other. One of the fortigate uses static IP while the other fortigate uses static domain names and dynamic IP. Before you configure, you need to unify VPN policies and parameters such as schemas, encryption algorithms, authentication methods, DH gr

a high quality capacitor recognizer. Microsoft says OEMs will deploy this recognizer in future keyboards, notebooks, tablets, and other devices. Hallum did not give a specific release time, but revealed that consumers will see it before the end of the year. In addition, he revealed that the surface keyboard would probably be the first hardware to use the technology. Unlike the existing recognizer, Microsoft's upcoming recognizer will identify whethe

Apple's official website gives detailed instructions on how to use Apple's devices to grab packets, which are handy for using remote virtual Interface (RVI). Using the RVI functionality requires a Mac system, and the Mac system on hand does not have the Wireshark software installed, in order to easily see the packet, using the Android system mentioned in the previous blog is similar to the grab method, that is, the use of Netcat (NC) The software esta

RAR for Android is an old WinRAR free Android tool that allows you to compress and decompress files on Android devices. Via @Xang Azu WinRAR, who ranks ahead of the piracy rate in China, has released a free decompression tool to support RAR, ZIP, TAR, GZ, BZ2, XZ, 7z, ISO, ARJ formats. RAR for Android also supports the choice of compression rate, volume compression. Unfortunately, there is no sharing tool inside, and there are other tools to shar
