During connection, you may be prompted "whether to connect to an insecure wireless network ". First confirm the connection, and then perform security encryption after the wireless LAN connection is successful. After a normal connection, the current signal strength is displayed in the network properties. Software f

You can simply add them directly. Other projects mainly remove comments. In fact, you can directly copy the following content to the configuration file:Net. ipv4.ip _ forward = 1 Net. ipv4.conf. all. send_r

I saw a good article about the pseudo-terminal. I posted it and studied it in another day. Many network service applications such as L2TP, PPTP, and Telnet on Linux use pseudo terminals. Some may ask about this concept and write down what I know for discussion. I. TerminalTo understand the Pseudo Terminal, let's take a look at what is the terminal ). A terminal is a type of terminal device. It has multiple types and generally uses tty for short. 1. Se
