A malicious user may use a Sniffer tool like Sniffer to perform local monitoring on the Administrator host or an appropriate interface to obtain the Administrator's password for logging on to the Cisoc router. So how can we use SSH to enhance the remote management of Cisco routers? 1. Security Testing I installed sniffer locally and used Telnet to log on to the Cisco router. Stop sniffing and decode it. 1 shows that the user logs on to the vro in user

Nowadays, many companies and enterprises are connected to their own networks. Especially for small enterprises with small size and few employees, it is unnecessary to apply for high-capacity fiber-optic bandwidth, therefore, using ADSL has become the choice of many leaders. The entire company only needs to buy a Broadband Router and then complete the company's network requirements through simple configuration.However, because the hardware inside the Broadband Router is very simple and its functi

Sometimes, when the distance between the subsidiary company and the company is not far from each other, you can directly connect the two routers with serial lines. This method can save the cost of laying optical fiber, but the transmission speed will be affected, and the distance between the two routers must not be too far.As shown in network topology 1, two vrouters A and B are connected to their S0 ports

Users who have been familiar with broadband routers generally know that the ports on the broadband routers are divided into WAN ports and LAN ports. A Broadband Router has the following features during work: data streams from the LAN to the WAN are not restricted by default through the router, and data streams from the WAN to the LAN are not allowed by default. Note: The wireless access part of the Wireless

When laying an IPv6 network, we must improve the existing routers. Now, let's introduce the IPv6 core router launched by Huawei. Based on the devices, we can also set up corresponding networking solutions. ; Huawei recently launched the first 10 Gigabit IPv6 core router NetEngine 5000E (NE5000E) in China ). Adhering to the fifth-generation router concept, this device adopts distributed and scalable design based on advanced network processor technology

Source: bkjia.com As more and more users choose wireless to improve the mobility of their work, wireless security has also attracted much attention. It can be said that wireless networks are more difficult to protect than wired networks, because the number of fixed physical access points is limited, and any point that wireless signals can achieve may be used. At present, major brand manufacturers have added a variety of methods in the configuration design of wireless

Environment In a small office, you can activate China Telecom ADSL Broadband and use a NETGEAR wireless router to share the Internet. In the corner of the meeting room, the signal is weak. How can we effectively improve the coverage of wireless networks? Solution Confirm that the original model supports the wireless relay (WDS) function, purchase a new Netgear wireless router, and perform wireless relay with the existing wireless routes. Note]If the original wireless router in the office belongs

In modern office life, the network environment is complex. Generally, several networks are connected to the network, such as routers and switches. It is quite simple to add a switch, it can be used almost as long as it is connected, but it is troublesome to add a vro. If it is not set, it will cause a lot of trouble, this article describes how to connect two H3C routers. I. Preparations before connection 1.
