An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the

I came back again, the last two articles introduced the Huawei Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.First, the topological enviro

Vswitch span technology Overview + Cisco configuration example 1. Introduction to span The span technology is mainly used to monitor data streams on vswitches. It can be divided into two types: Local span and remote span.---- Local Switched Port Analyzer (SPAN) and remote span (rspan) have slightly different implementation methods. Using the span technology, we c

file (that is, the configuration of the SSHD service is enabled on the computer), and Ssh_config is a global client profile. For example, two of the lines in Ssh_config define the path of the default private key key for each user: # Identityfile ~/.ssh/id_rsa# Identityfile ~/.SSH/ID_DSAIf multiple private key files a

supports SSH. log on to your vro or vswitch and check whether you have loaded an IPSec IOS image that supports SSH. In our example, we will use the Cisco IOS command. Run the following command: Router> Show flash This command displays the name of the loaded IOS image. You can use the result to compare the list of supp

iOS supports SSH for high-end products such as the 7200 series, 7500 series, and 12000 Series (GSR) in the Cisco routers product family. The iOS version of the general support SSH file name is K3 or K4 words, K3 for 56bit SSH encryption, K4 represents 168bit SSH encryption.

Set an instance for SSH on a Cisco device Http://www.pcdog.com unknown When using telnet for remote device maintenance, SSH should be used instead of Telnet because passwords and communications are in plain text and are ea

port is 22. By using SSH, all transmitted data can be encrypted, which is not possible in the "man-in-the-middle" attack mode above, and can also prevent DNS and IP spoofing. In addition, it also has an additional advantage that the transmitted data is compressed, so it can speed up transmission. 3. SSH deployment Based on the above tests and SSH security featur
