test ping lol

The ping command is not able to test the port, Ping is only testing network connectivity and packet send and receive status. Format: Ping IP address or host name [-T] [-a] [-N count] [l size] Parameter meaning:-t keep sending data to the target host;-A to display the network address of the target host in the IP addre

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

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

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