Layer 3 switching technology: layer 2 switching technology + layer 3 forwarding technology. It solves the situation that the subnet in the network segment must be managed by the router after the division of the network segment in the local area network, and solves the network bottleneck problem caused by the low speed and complexity of the traditional router. Experimental requirements: C1 and C4 belong to VLAN10,C

How to prohibit mobile devices such as mobile phones from accessing the office network-Niu Dun Technology Co., Ltd., founded in 2009, is committed to becoming a network security equipment supplier and security provider. The main R & D members of the company come from research institutions in Silicon Valley of the United States, Taiwan and domestic universities.
Another protocol to implement * * is ipsec. To be exact, ipsec is a framework for a combination of multiple protocols. Its implementation can be divided into the following four steps: 1. Realize the filter control of data flow (controlled by acl) 2. Security proposal (implementation of working mode, selection of security protocols
Fail2ban is a well-known * protected open source framework on Linux that monitors log files for multiple systems (such as / var/log/auth.log or / var/log/secure) and detects any suspicions
How to install the original system with USB flash drive? U disk can not only store and transfer files, but also can be used to make a boot disk to install the system, and then take the U disk as an example to introduce the operation of the original system on U disk, hoping to help you. Pre-production preparation of USB disk boot disk (pay attention to operation preparation)
There is a Plugin configuration in MyBatis's Configuration configuration, which can be interpreted as "plug-in" according to its name, which in essence can be understood as "interceptor". The term "interceptor" is not unfamiliar, and there are "interceptors" in many frameworks. This Plug.

Before configuring the switch, you first need to connect the switch to the computer. Here is a detailed explanation of Huawei S5700S-28P-LI connecting to the computer. First, download a Huawei Console driver: then, use the configuration line to connect one end to the RJ45 interface of the console port of the switch.
When I first looked at the ping principle and the ICMP protocol, I always felt that the network protocol could only be encapsulated layer by layer. Although looking for information, it was said that there were IP protocol, arp protocol, ICMP and IGMP protocol on the network at the same time, but I just couldn't make a detour. Now think about it, alas. P

The previous blog wrote about how to configure NAT under the environment of VMware ESX and XenServer, which solved the problem of internal network virtual machine accessing external network, but not the problem of external network accessing internal network. It is too troublesome to add several mapping rules for each additional virtual machine, so that all the ports are mapped.
Kerberos is a service security management system developed by MIT to verify and authenticate the three parties, which well embodies the idea of separation of powers in the West. The name comes from the Greek mythology Hell's three-headed watchdog, which also passed by in Harry Potter. Yeah, jump. Jump into the pit.
WinPcap is an open source library based on Win32 platform for capturing and analyzing network packets. Most network applications access the network through widely used operating system components, such as sockets. This is a simple implementation, because the operating system has already
NBAR (Network-Based Application Recognition) means network application identification. NBAR is a technology that dynamically discovers protocols from layer 4 to layer 7. Unlike ACL, it only depends on the port number for application.
Symmetric key algorithm and asymmetric key algorithm the two common cryptographic algorithms in cryptography are symmetric cryptographic algorithm (single key cryptographic algorithm) and asymmetric cryptographic algorithm (public key cryptographic algorithm). The so-called symmetric key algorithm means that if the encryption key and decryption key of an encryption algorithm are the same, or although different, but
First, stop position stop position, that is, the position where the gradient begins. 1) different stop locations will have a transition effect. The starting position of # fb3 is 20%. Before 20%, there is only # fb3, and to 80%, it is # 58a. Div.transitio
