The original Article is from BlackSun. It is translated in sleep hours. This is a very good article and I am very happy to share it with you! Warning: Do not use this to damage the cisco system or access the system illegally. This article is for the purpose of learning. It can only be used for legal actions and cannot damage any system. This article will show you step by step how to use the discovered defects to obtain illegal access. If you break int

One, the internal components of the Cisco routerIn order to configure, Cisco Internetwork and troubleshoot, we must first understand the major components of the Cisco routers and understand these componentsThe respective function.Table 7-1 gives a description of the major components of the Cisco

Configuration mode for Cisco routers Configuration mode Prompt Enter command Description User mode Route> User mode is the default mode when the router starts, provides limited access to the router, allows for non-destructive operations such as viewing the configuration parameters of the

Cisco routers use many methods in configuration. Using SSH instead of Telnet cisco makes it easier for us to understand the configuration of cisco routers and other knowledge points. Replacing Telnet with cisco router configuration using SSH　The Telnet protocol is a member o

We will discuss the record and storage of Cisco router logs in the following steps. First, display the log information for the line, then save the log information to the log server, and finally send the log information to the SNMP Management Terminal. Configure the option for sending log information Log information is generally the alarm information generated by the system in

Users using Cisco routing, many of them do not pay much attention to doing Cisco router configuration work, in fact this is a very important part, especially for our network security. There are several ways to do Cisco router configuration. The configuration can be done by t

Many junior network administrators ignore security settings when using Cisco routers, and the following three are ideal for novice users to configure network security when using Cisco routers. One, the security configuration of the router "access control" 1, the administrator who can access the router is strictly con

This article describes the upgrade steps for Cisco IOS software mirroring on the access router platform. The upgrade instance for the 2600 and 3600 series routers also applies to the router platforms listed below. Cisco IOS software filenames may vary according to Cisco IOS

A Cisco router is a network device that connects multiple networks or CIDR blocks. It can translate data from different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network. A vro consists of hardware and software. The hardware is mainly composed of physical hardware and circuits such as the central processor, memory, interface, and control port. The software is main

After decades of development, from the first four-node ARPANET to the ubiquitous Internet, computer networks have penetrated into our lives. With the explosive growth of the computer network scale, as a router to connect devices also become more important. When a company builds a network, how to reasonably configure and manage the router becomes one of the important tasks of the Network Manager. This topic

I would like to introduce how to obtain the IP traffic of a Cisco router. Many people may not know how to retrieve the IP address of a Cisco router. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. A

I have learned some useful questions about the password of a Cisco router. So I have studied how to use the password to protect a Cisco router. I would like to share it with you here and hope it will be useful to you. The most serious cause of security problems is often because people ignore the most basic security mea

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in Cisco routers has many

A Cisco router is a commonly used routing product in large and medium-sized networks. As a core router, It is the soul of the entire network. If the Administrator is improperly set, the security deployment may be taken over by attackers if it is not in place. In that case, all the networks under it will fall, and the extent of its harm is self-evident. 1. One Sec

Which command standard do you want Cisco to use on each vro? Each administrator configures the commands of each vro correctly. The ten commands in this article are what I think you should configure on each vro, with no special order. 1. configure a Logon account on the vro I strongly recommend that you configure a real user name and password account on the vro and vswitch. This means that you need a user and a password to gain access. In addition, we

The features of Cisco Wireless routers have previously been introduced to you. Today, we are trying to better understand the source of the vulnerabilities and the inner relationship between the vulnerabilities and functions. Recently, it was found that Cisco Wireless Router allows hackers to easily access the network configuration page of the
