Using ping command send message

The ping command in Linux serves the purpose of testing the accessibility and round-trip time of a network host or IP address. By sending ICMP Echo Request packets to the designated destination and awaiting ICMP Echo Reply packets in return, it becomes a widely utilized tool for verifying network connectivity and assessing network latency.

Explore how to convert the simple text message “” into its hexadecimal representation and then send the hexadecimal message using the Ping command. Understanding hexadecimal representation is crucial for working with low-level data and network protocols. Let’s get started!

Step 1. To initiate the process, we will use the ping command from the first device to send a packet to the target device.ping -p [hexcode of message] [IPaddress of the other device]

Step 2. On the second device, we will employ the tcdump command to capture the incoming packets from the first device, enabling us to monitor the communication.

tcpdump -X        

Step 3. Once the packets are successfully captured, we will be able to examine the messages contained within them, which will be displayed on the right side of the captured data. This information will provide insights into the communication exchanged between the two devices.

conclusion, the process outlined above allows us to send packets from one device using the ping command and capture these packets on the other device using tcdump. By analyzing the captured packets, we can access the messages contained within them, gaining valuable information about the communication between the two devices. This approach enhances our understanding of network interactions and facilitates troubleshooting and monitoring tasks.
