ipv6 ping test

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

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] ~]#

Shell script ping test (Code instance), shellpingShell script ping Test Principle: use shell scripts to execute a ping command. 1) The destination_ip variable is the IP address of the target host. 2) The-c1 parameter after ping

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

27.3 "Linux learning is not difficult" Linux Network Command (3): ping command to test connectivity to the target computerUse the ping command to test connectivity to the target computer. The ping command uses the ICMP transport protocol to emit information that requires a r

The ping command is not able to test the port, Ping is only testing network connectivity and packet send and receive status.

This example is used to detect the normal communication between the host and the Ping class. Delay how many milliseconds, etc...

The simplest way to test the computer's network speed is to directly use ping to solve this problem, For example, in Nanchang, you only need to enter Ping 202.101.224.69-T in the running state to view your network speed, If you are in Jiangsu, ping the DNS server address in Jiangsu. As follows:202.102.29.3202.102.13.14

Because the friend said the port is not connected, deliberately tried the ping test with PHP, the result is quite satisfactory. The code and the run diagram are as follows: (if there is a great God to improve the better) $host = ' www.php100.com '; $port = ' 80 '; $num = 3; Ping times Get time function Mt_f () { List ($usec, $sec) = Explode ("", Microt
