I. background The current network has a pair of Juniper mxbench routers that have just been put into use. They are only interconnected with the current network's one-to-one Huawei NE40E, and the interconnection link uses optical ports. Currently, mxbench needs to connect to a Huawei NE20 instance in a remote data center through a transmission network. The commissioning has not been successful. To verify that mxbench's optical port is normal, disable the connection between RT4 and RT2, temporaril

Use ping and net view commands to test TCP/IP connection 1. To use the Ping command to test the connectivity of TCP/IP, use the ipconfig command to make sure that the network adapter is not in the "Media disconnected" status. For more information, see "NOTE ". 2. Open a command prompt and use the IP address to

Run the ping command to test the IPv6 connection. To obtain IPv6 configurations for the computer, open a command prompt and enter netsh interface ipv6 show interfaceInterfaceName, where InterfaceName is the name of the interface on the computer. For example, if you have an interface named "Local Area Connection", Type netsh interface ipv6 show interface "Local Area Connection". If IPv6 is not installed, see

Ping (Packet Internet groper) is one of the most frequently used tools in network testing, which determines whether downlevel connections between two or more network nodes are available, and provides basic network performance statistics that can help diagnose network problems related to communications.The language format for the ping command is as follows:[[email protected] ~]#

1. Requirements Description working environment, often use to ping network on the host to do network testing, such as the machine shelves, offline, testing and other needs, for a large number of machines, one by one host ping test, obviously difficult to meet the requirements, for the machine more than the scene, The IP address that needs to perform the

following judgment on the key file. If the key is in the minions_rejected directory, the connection is rejected. If the key is in the mini-ons directory, verify that the pub key is equal. If not, add it to the mini-ons_denied directory; if the key is not in the minions_pre directory, the key is written to the minions_pre Directory. If the minions_pre does not exist, if the pub key verification fails, the key is added to the minions_denied directory.Activity diagram of the minion authentication
