The user checks network security and requires SSH logon to the core device. Previously, the device used Telnet logon, and the user name and password are transmitted in plaintext, which does not meet the security check requirements. In fact, the SSH login configuration is very simple, mainly divided into the following steps: 1. Configure the Domain Name Sd_core_r7

When we use Telnet to log on to the device, the user name and password are transmitted in clear text, in order to ensure the security of the data, we recommend the use of SSH login device. The following is the configuration of the Cisco router SSH:1. Configuring hostname and Domain-nameR1 (config) #hostname R1R1 (confi

Cisco routers play a very important role in the routing industry, and there are also a lot of user groups. It is very important to understand some Cisco router security configurations. Currently, most enterprises and departments connect to the Internet. Generally, a router is connected to an ISP. This router serves as a bridge between the external Internet and the internal network. If this router can proper

The market demand for Huawei routers and CISCO routers is very high. So I studied the differences between the configurations of Huawei routers and CISCO routers. I would like to share with you here, hoping to help you. The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are e

There are many things worth learning about in the configuration of a Cisco Wireless Router. Here we mainly introduce how to use a vro to set up a PC to share the Internet, including knowledge about DHCP, security, TCP/IP network protocols, and so on. As a product designed specifically for broadband Internet sharing, a Broadband Router has the advantages of simple and convenient Internet sharing, high securi

Comments: This article describes the basic configurations of Cisco routers. The configuration process of Cisco routers is still complicated, and there are many factors to consider, especially in terms of security. In fact, there is no need to make the router think so complicated. In fact, the router is a computer with multiple ports, but it plays a different role

The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are exactly the same, and some of them have also been improved according to the needs of domestic users. For example, the configuration and debugging interface that can be switched between Chinese and English makes Chinese u

This article mainly introduces how to configure the vro for Cisco IOS configuration lock to prevent configuration disorder. I believe this article will help you. If multiple network administrators connect to the vro at the same time to modify the configurations, the changes may be lost or only part of the content can be executed, resulting in problems in the oper

. Setting up TelnetTelnet has a version of the change. Before the PIX OS 5.0 (the version number of the PIX OS), the PIX can only be accessed via Telnet from hosts on the internal network. In PIX OS 5.0 and later versions, Telnet to PIX Access can be enabled on all interfaces. When you want to telnet to the PIX firewall from the external interface, the Telnet traffic needs to be protected with IPSec, which means that the user must configure the PIX to establish an IPSec tunnel to another pix, ro

that you need a user and a password to gain access. In addition, we recommend that you use a secret password for your username, instead of a common password. It uses MD5 encryption to encrypt passwords, and greatly improves security. Example: Router (config) # username root secret My $ Password After the user name is configured, you must enable the port using the user name. Example:◆ Router (config) # line
