In the following sections, we’ll go over the most commonly used ping command options. This can be useful when using the ping utility in a shell script.

Otherwise, it will exit with code 1 or 2. On success, the ping command exits with code 0. Some hosts may have a firewall that is blocking the ICMP traffic or set to not respond to ping requests. When this happens, it doesn’t always mean that the destination IP is not active. PRTG monitors the website network traffic and detects load peaks.

It comes with a Cisco IP SLA Sensor that measures the rate of packet loss on the devices. The Quality of Service (QoS) Round Trip Sensor allows you to monitor the network to measure packet loss and reduce it. If ping does not return a reply, it means that the network communication is not established. PRTG Ping Sensor is used to measure packet loss on a percentage basis. Packet Sender can also send SSL (encrypted TCP) packets. If there is a packet loss, you can use the traceroute command to identify where the packet loss occurs. Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. The packet loss means the data was dropped somewhere in the network, indicating an issue within the network. Once the command stops, it displays a statistic, including the percentage of packet loss. To stop the command, just hit the Ctrl+C key combination. The ping command will continue to send ICMP packages to the Destination IP address until it receives an interrupt. time=41.4 ms.īy default, the interval between sending a new packet is one second. The ping time, measured in milliseconds which is the round trip time for the packet to reach the host, and the response to return to the sender.The ICMP sequence number for each packet.The IP address of the destination - from (172.217.22.206).The default is 56, which translates into 64 ICMP data bytes - 64 bytes. If the destination IP is reachable it will respond back and the ping command prints a line that includes the following fields: The ping command resolves the domain name into an IP address and starts sending ICMP packages to the destination IP. To better illustrate, how the ping command works let’s ping : ping
