The problem is that the Ping command requires a direct network connection between the nodes. It is the man in the middle who makes the request directly to another node. The destination node can be specified by an IP address or a hostname.Ī proxy is a server or application that acts as an intermediary for the connection between two points on a network.
No matter how many packets the command has sent or received. -w: Specifies a time in seconds that the execution of the command will end.-s: This option allows you to change the default size of the packets.
-c: With this option, you can specify how many packets to send.Some of the most useful and used options of the ping command are the following: The syntax of the command is as follows: ping However, the information that the command will generate will judge whether the network is in good or bad condition. Then, after you send the packet, the command verifies and measures the time it takes to receive a response from the destination node.Īs you may expect, the response time may be affected due to conditions such as the geographical location between the connection points or any piece of the hardware used between the two nodes.įor example, in wired private networks, the command will get better times than with a network with multiple routers or bridges. You can test this node using either the IP address or the hostname.
#LINUX PACKET SENDER EXAMPLE SERIES#
The command sends a series of small packets to a specific node. In Linux, the functioning of the ping command is quite simple to explain. It allows knowing if there is a connection with specific equipment.Īs you can see, it is a necessary command for the administration of networks and servers.The ping command can be used in a bash script to perform automatic checks with network nodes.We can use this feature on both the Internet and in a private network. We will also be able to identify the IP address of a specific host.Measure the time taken by two network nodes to communicate.On the other hand, it is also useful to perform other diagnostic tasks such as the following: In this way, it is possible to know if a network node has lost connectivity. Its purpose is to diagnose network connection errors. The ping command is one of the most basic tools for working with networks.
